Mentors and mentees usually have many things on their table with work, personal projects, and their training paths. Learning opportunities are infinite, but the time available is not. How can we foster productive mentoring relationships without consuming our time communicating and aligning our expectations? Read on to learn how a mentoring agreement can help you streamline the mentor-mentee relationship, making communications more efficient, and setting the — sometimes hidden — expectations on both sides of the deal. My struggles navigating the mentorship program At Eventbrite, we run an engineer. During six months, developers and leaders both mentor and receive mentorship from their peers. A committee matches participants depending on the skills they want to learn or teach. The program has happened a couple of times already, and I have always had hardworking mentees and great mentors. However, during the initial cycle, I struggled with several aspects of the relationship. The first issue was accountability and commitment: How could I motivate my mentees to get things done and make the most of our time? Also, how could I do it without coming off as pushy or too demanding? Other challenges I faced were inefficient communications or lack of clarity in the goals and expectations. As a mentee myself, I assumed my mentors might be experiencing similar challenges. With these issues in mind and craving to improve, I did some research looking for solutions. The mentoring kickoff meeting The mentoring kickoff meeting is a quick gathering where mentor and mentee set goals and talk about how they will measure their achievement. However, the most critical part of the kickoff meeting is to read, understand and clarify the points of the mentoring agreement. What is a mentoring agreement? A mentoring agreement is a reference document where mentor and mentee agree what are their commitments during the period they work together. The agreement highlights what mentor and mentee are going to do, establishing a two-way relationship. It also makes accountability an official part of the mentorship experience and helps identify areas where either mentor or mentee need extra support. The agreement specifies how communication happens between the two participants, establishing the channels you are going to use and striving for openness and transparency in the communication. Discussing what the mentee will do and by what date is essential to make the mentoring experience productive. You need to know what success looks like to achieve it. I like to keep the mentoring agreement short, with five to eight bullet points per role. Some points are intentionally vague, leaving room for interpretation and ongoing discussion. Although you could say this is all common sense, there is value in making it explicit. It is more efficient, as you compress several conversations into one. Moreover, you demonstrate the value you bring to the mentorship experience by running it like a pro. In my first try, this agreement has worked well: it reduced communication overhead, and my relationships have been more productive. I will admit that from time to time I have let a deadline slide for fear of affecting the relationship. Would you add anything else to this agreement? Is there something you think is helpful to mention? Drop me some lines below or ping me on Twitter. Photo by Mimi Thian on Unsplash Tagged , Raquel was mindlessly browsing Instagram on her Pixel 3. Her thumb repeating the same gesture over and over again — until she found an image that intrigued her and then tapped the hashtag octoberfest in the comments. Read on to learn how we did it. It all starts with data At Eventbrite, we have two sides to our marketplace-based business: the business organizer side and the consumer attendee side. With 3 million events published in 2017, there is a huge user experience problem with trying to show an increasing amount of events onto your mobile screen — all at the same time. So my team and set out to improve the event discovery experience, which started with our home screen — a simple feed of upcoming events. The event discovery funnel With a need to understand how people physically wanted to explore events the team first needed to understand the consideration process for attending the event. Understanding these three core influences is necessary to power the backend response and put the app in a position to show a high-possible conversion event. While seemingly straightforward, the three influences are relational to each other in that if one of the influences is problematic in regards to attendance , then the others can overcome the adverse effect of it. The event itself is the draw inventory , but the level of commitment needed to travel to Burningman means that I need lots of good friends going to make it happen attributes. We wondered if the transition between the two mobile gestures swiping and tapping was fluid back-and-forth or if it was funnel-based goes one-way and if these gestures correlate with intent to attend an event. Qualitative assessments showed that the Home Feed with its vertical-infinite scroll was highly used with a swiping gesture. As users would find events or canned searches that interested them, they would move to a tapping gesture to dive deeper. Moreover, once a user wanted to find a specific event they would leverage the keyword input for search and begin typing. Interacting with push notifications complemented this discovery experience. Top-level user interactions with push notifications also complemented this discovery experience. This is the least amount of effort a user can provide since it is virtually none and corresponds with zero intent. This browse experience is a simple repetitive action that the user can do even if they are bored and looking for something to do an everyday use case and corresponds with a low level of intent. They take out their second hand and enable the keyboard with the maximum amount of physical effort that can with the highest level of intent. These four gestures map back to the physical patterns expressed during the serendipitous event discovery moments — without all four any product is missing a fundamental discovery use case needed to be successful. What does this mean for me? However, once you look to improve upon that initial output make sure to design the navigation elements of your user experience to correspond to the intent of the user — then pair with qualitative research to understand the variables in decision making for users and how they compliment each other.

Tagged , , , , , , , , , , PyConES is the main event for Python developers in Spain and a must-attend for the engineering team based in Madrid. We meet the Python community every year, so we have a chance to catch up with fellow developers from other parts of the country. We learn a lot from them as we share our most recent experiences, either through our sessions or while hanging out with a coffee in hand. The trip to Málaga PyConES is celebrated at a different location every year so that everybody gets to attend at least once, to share the hard work among various members of the community, and —why not— to showcase beautiful Spanish cities. This year we attended PyConES at Málaga. That allowed us to meet some attendees before the event. Once at the conference, we were glad to see that 25% of the attendees and 33% of the speakers were female! One of our Britelings, Federico Mon , was a mentor for the workshop and he enjoyed it. While this was the first time for Eventbrite to attend the conference, the Spanish team in Madrid had participated many times in the past years. We were committed to satisfying the curiosity of everyone visiting our booth —which was a lot, by the way. Eventually, people got to know the brand and gained interest in it not as a platform, but also as a nice place to work in the center of Madrid. We met lots of people who want to come and visit us at our office! When people visited our booth we had the chance to chit-chat with many of them, give them some Eventbrite goodies very cool ones if you allow me , and discover their interests. We met many young people, a more significant amount of female attendees than at any other conference we attended this year. Among them were some non-devs that wanted to start with programming, and many data scientists as well. We can assert that the Python community is — hands down — one of the healthiest ones out there. Also, we are hiring! First of all, we want to thank the organizers of Python Spain, speakers, sponsors, and attendees for making it a great conference every year. We are looking for passionate React and Django developers and also Site Reliability Engineers. For more about other conferences Eventbrite has been attending so far,!

The atmosphere Set in the Melia hotel, overlooking the Mediterranean coast and its rocky shores, the conference venue location was enviable. Inside, a small group of sponsor tables lined the conference room lobby. We had 14 Britelings in the house and our very own speaking at the event. The Lonely and Dark Road to Styling in React Sara Vieira walks us through the dark alleys of styling with CSS in ReactJS apps. Sara starts her talk by reassuring us that CSS is hard. We know all about that here at Eventbrite, where we use a design system to speed up our development process. This often keeps us from having to walk The Lonely and Dark Road to Styling in React. She walks us through the pros and cons of everything from link tags to, and her main focus, The Year of Web Components Dominik Kundel reminded us, once again, that web components are out there and this is their moment! What are web components and why should you care? Web components are a set of building blocks, defined as WC3 web standards, that allow the browser to natively interpret the reusable components we frontend developers love so much. We often think of frameworks like ReactJS or when componentizing our code, but what if we could write reusable components that were framework agnostic? Next Generation Forms with React Final Form Here at Eventbrite, we know the joys and pains of working with forms inside of ReactJS. When Erik Rasmussen hit the stage to offer one Form to rule them all, our ears perked up. The author behind went back to the drawing board and iterated a new solution for forms. My React app is slowwwww! Last but not least, our very own Principal Software Engineer, Ben Ilegbodu , hit the stage and got our blood pumping with a quick workout. As a premier ticketing platform, the last thing we want is for our website to feel slow for our users. Ben covers everything from breaking up component markup to combining Redux dispatch calls. The best talk Choosing from the long list of great talks is hard. Which talk was your favorite? Drop us some thoughts in the comments or ping me in Twitter. Some even think that with good code, tests are unnecessary. For a small project you are working on, that might be ok. You know the definition, the implementation details, and the desired behavior because you created them. Keep on reading and learn why unit tests are an essential part of your development workflow and how you can start writing them for your new and legacy projects. For those who are unfamiliar to unit testing, you might want to start with a. Eventually, I opened the code and faced what I had left undone the day before. No tests whatsoever, of any kind. Nobody in particular, of course. We need to prevent this from happening again. I usually forget what I broke — and, especially what I fix— these missing tests should be the first to start with. Unit tests are the definition. By testing, I force myself to make it extendable and parameterizable, allowing me to think about any possible input and output. If I have tests that cover my particular case, it is easy to cover the next ones. By testing, we realize how difficult it could be for others to extend our first implementation. Tests are proof that it works, your best friend and lawyer. Moreover, if someone messes up and your code is included somewhere, chances are developers summon you to illuminate the situation. Probably your tests will guide you to narrow the issue. Writing tests first, before actually writing any real code is the fastest and most reliable way to accomplish that. I can estimate how much time I spend writing tests. I cannot estimate how long I will spend in front of the debugger trying to figure out where things went south because I made the whole thing a little too complicated. Now I want to write unit tests. Maybe they think there is still too much work to do, of that if you were to write all the missing tests, that would take weeks, even months! How can you explain this to your Product Owner? Just ensure that you add a couple of tests will every time you merge code. This means that when you test a component which affects others, you can ignore them. Make the component testable instead of testing everything around it. Rather, try to split it into smaller pieces and test each individually. Run tests using different languages and time zones, for instance. The fewer components involved, the easier it is to test yours. Create compelling public APIs and test them. Ignore implementation details, as they are likely to change, and focus on input and outputs. Remember, these tips work well for a codebase with no tests. The very first time you are about to fix, refactor or change the behavior of any part of the code, you must write the tests first to ensure you are not breaking anything. However, when working with legacy code, you would likely see the test coverage increase as the code changes. Conclusion In this blog post, we included some pieces of advice taken from our own experience with unit testing. There are other types of tests, but if you and your team want to start testing, unit tests suit you best. One nice thing about testing is that you make a massive leap towards coding from the outside out — instead of from the inside out, which is usually better for the implementer, and never for the user — which turns out to create a more elegant, comprehensive, and extendable code. It goes without saying that. Is there any other tip you would suggest to newcomers? Drop us some lines in the comments or ping me directly in Twitter.

Tagged , , Making the leap to being a manager is one of the most challenging transitions an individual contributor IC can choose to make in their career. In front of an audience of peers and senior engineers — some friendly faces, but mostly all strangers — I shared how dropping the ball as a new manager was, in fact, an invaluable lesson. You can hear me expand on these points as my presentation was graciously captured on video and you can see it here: Radical Transparency: Biggest Learnings From Transitioning to Management About 10 minutes in, I flip to being the interviewer, navigating a fantastic discussion packed with insights between four esteemed panelists — Yi Huang, Sue Nallapeta, David Murray, and Hala Al-Adwan — who hold engineering leadership roles at Facebook, Zoosk, doctor. I hope others also benefit from my shared tale of woe when navigating their own transitions into the next level. Tell us about it in the comments. Tagged , , I just came back from the , where I joined another 22,000 women in the world largest gathering of women technologist. Keep on reading to learn about the most inspiring, surprising, outstanding and best career advice I got from the 2018 event. My VP at the time recommended I attend. Unfortunately, it was way too late to register, but I tuned into the live stream of the keynotes and felt inspired just by watching remotely. On the day registration opened, I blocked off my calendar to refresh the site until the magic registration button appeared. When I got my ticket, it was almost surreal! There were several learning tracks this year, and the most popular were artificial intelligence AI , mentorship, and career development. There are five different session types — panel, workshop, presentation, mentoring circles, and poster sessions. Most Inspiring Jessica Matthews, CEO of , gave an inspirational keynote about how she started a company that develops kinetic energy storing products. She immediately connected with the audience when she admitted that she strives to be the perfect love child of Beyonce and Bill Nye the Science Guy. Over her lifetime she visited her family several times a year in Nigeria and noticed a severe infrastructural problem in the community. Villages and even cities would frequently lose power for extended periods of time and their solution during these periods was the required use of kerosene lamps or diesel generators, which poses a significant health hazard from the fumes. For the class project, she developed a short-term solution. Her idea was to use a soccer ball to store kinetic energy as you play. When she started distribution of her new product, she learned that girls in refugee camps were not allowed to play soccer or play outside past the age of 12. To solve that challenge, she applied the same technology in the soccer ball to a jump rope. Jessica is building the cities of tomorrow and building them faster, more cost-effectively, and more durable. Without having her background or feminine perspective, none of this would be possible. In fact, her background has enabled her to have a unique perspective, to think about solving problems differently. Each one had a unique story to tell, and all of them either moved into a role where they had limited experience or had someone advocating for them to open up key opportunities. For example, one woman described asking for a discount for a recent purchase and she got the discount! One woman applied for a job she never felt qualified for but was invited for a job interview. In your career, it is about taking the right calculated risk. As you enter into the door, the displays resemble that of an amusement park with large signs, lights, and entertainment. Hundreds of recruiters were happily buzzing around their colorful and interactive booths with freebies ready to talk about their company. You could easily spend your entire week interviewing and take home an entire suitcase full of swag. As you pass by each booth, you can talk to one of the available recruiters about potential openings as you would at a typical career fair. If there is mutual interest, an interview will be scheduled later the same day. If interviewing is your intention when attending Grace Hopper, you can upload your resume to the Grace Hopper resume database. Companies are so eager to find talent; two attendees received job offers on the spot. This rate hit close to home as I submitted a presentation for this year that was not accepted, but after attending this session, I have a new strategy. The track is most important! You must choose a track that aligns to the content you want to present. Pro tip: Presentation or panel formats are ideal for first-timers. Career, mentorship, and AI stood out as essential themes for this year. Excited to see what will be hot for 2019. You must provide a catchy title, abstract, and detailed information to get your talk accepted. The organizers need more submissions for senior and executive women sessions. There is also a need for more advanced technical topics. Submitting in these areas help increase your chance of getting accepted. Most Outstanding Experience The best experience was meeting people. I met women from all over the world — DC, the Bay Area, Boston, and even Ireland. If either of us is in the same city, we each have an open invitation to meet in person. While the celebration is over, the inspirational message and excitement remain. Will I see you there? Tagged , , A couple of years ago I had an opportunity to be promoted. I evaluated the role. I had a plan for how I would implement in that role. I talked to the hiring manager my manager at the time. I talked to my network inside the company. I knew the competition and, in my estimation, I was a better fit for the role and for the direction the organization should take. I was certain I had the position in the bag. One of my peers got the position and became my new boss. I was devastated, humbled, and felt rejected by the organization. Looking back now, with the benefit of hindsight and many conversations while I was still employed at that organization , I know that I was suffering from a few key self-deceptions. I could not see the possibility of failure. I only talked with people in my network who would be most likely to confirm my assumptions. I left no room in my mind for doubt. Doing so, I blocked out the possibility of addressing any weaknesses I presented to the hiring manager. The result is emotional discomfort that we then attempt to resolve. Often, the resolution comes to us through further self-deception. What followed were additional self-deceptions to mitigate the weight of heavy emotions and soothe the pain I was feeling. One of the greatest gifts of this experience was the ability to look back and identify ways I self-deceive and the further turmoil those behaviors cause. In truth, we all struggle through moments of cognitive dissonance. To create cognitive harmony, we usually engage in self-deceptive strategies. Sometimes, our self-deceptions are incredibly useful. More often, self-deception is toxic. Like when organizations believe their plans are truth despite data that shows we never deliver work when we say we will, which results in a myriad of poor behaviors throughout organizations. Self-deception is subtle and hard to spot in ourselves. Joe Willful Ignorance Willful ignorance is a choice not to see information that contradicts our core beliefs. Every unresearched Facebook debate or meme provides an opportunity to identify this particular self-deception. At work, this looks more like picking a deadline without validating it against empirical evidence or without leveraging the wisdom of the teams doing the work. It can also be things like believing you are the best team member or worst without asking your teammates for feedback. Reality Denial Reality denial has a lot of overlap with willful ignorance. They are close cousins. Whereas willful ignorance is avoiding the consumption of information that conflicts with your beliefs, reality denial is refuting new information because it flies in the face of what you want or believe. Example 2 Though everything the team is telling me indicates that we will not meet the deadlines, as a leader, I will continue to insist that we still have to meet the deadline without any change to scope because I believe this is the only way we can succeed. Example 3 As an organization, we design open space offices because we believe our employees will be more productive, despite the data that currently indicates a reduction in productivity in open environments. Overconfidence Overconfidence is a lie we tell ourselves to elevate ourselves in our own perception. It can have significant benefits in that it helps us do things like public speaking or stretching our skills. It can also cause us to underestimate risks and difficulties in our efforts. My opening story was filled with overconfidence. The result was that I did not prepare the way I should have for that role and those around me easily saw that lack of preparation. Self-enhancing Self-enhancing deceptions are a close cousin to overconfidence. In this case, we enhance ourselves to prove to others how awesome we are. Blustering, exaggerating, and one-upping tend to live here. Self-handicapping On the other side of the spectrum, we have self-handicapping. Insecurity and can play an essential role in perpetuating this deception. We use it to protect ourselves from the perception of inevitable failure due to our belief we lack the skills or knowledge to reach our goals. You might even walk away with a clearer understanding of what work you need to do. Alternatively, you could get the role. Confirmation Bias Confirmation Bias is the act of ingesting all the facts but only seeing those that support or confirm what we already believe. This can show up in offices when we only select articles that support our viewpoints to make our points with colleagues. We can also see this in the people we choose to spend time with by creating an echo chamber of agreeable opinions. The latter is particularly troublesome if the person creating the echo chamber is in leadership and is only hiring and promoting people that agree with their choices and vision. Self-serving Bias Self-serving bias is when we credit our success to our hard work and our failures to external factors. In my opening example, I allowed a self-serving bias in my thinking to soothe my hurt feelings. The belief that what people do is representative of who people are is what prompts this error. Self-deception, at its core, is a lie. Generally, other people are better at seeing reality than the person in the throes of self-deception. This interplay undermines trust between individuals, on teams, and inside organizations. Trust is necessary for psychological safety. Psychological safety is necessary for high productivity and effectiveness. Also, in individuals, the ability to grow is stunted. Either they do not see their flaws or they do not see their strengths. In leaders, this can be exacerbated since organizations can only grow as far as their leaders have grown. Sometimes, self-deception is just what we need to be a little more humble or to spur us to act courageously. An individual might enhance herself through her personal brand to find a new job. It comes down to self-awareness, choice, and a little bit of humbleness to encourage the positive outcomes of self-deception and discourage the negative ones. Choosing Right Action over Passive Self-Deception Practice Self Awareness Self-awareness is a mental muscle. Like other muscles, we can exercise and make it stronger over time. How is this deception hurting me? You may not be able to catch yourself in the moment. Sometimes looking back at a situation can be enough. As you evaluate the self-deceptions we covered, was there one that brought forward a clear example for you? Leverage that experience and hold these questions up to it. Often, our self-deceptions are well-worn paths of habit. By looking at your patterns in one situation, you can find your patterns in the present and future. Get out of your echo chamber. Welcome opinions that are uncomfortable. Surround yourself with people who challenge you to question your beliefs, values, and intentions. Once you do that, then you have to listen. Be ready to be challenged. To do that takes vulnerability and it is easy to fall back into self-deception in the midst of dropping our guard. It will feel unsafe. It is easy to become defensive and leverage self-deceptions to protect your perception of self or diminish negative emotions. Go courageously into the midst of your closest friends and loved ones anyway. Tagged , , My first day as a junior software engineer was one of the most mentally draining days of my life. I remember thinking, What did I sign up for? Read on to learn what your company needs to provide to avoid overwhelming situations for junior engineers and to make it easy for them to be a contributing member of your organization. Being a junior engineer I had been coding since I was twelve, but coding was fun. Working as a software engineer was something else. I felt like everyone else in the room was reading Shakespeare and I was trying to get through a copy of Goodnight Moon. I was the first junior engineer that my company hired. After that, I worked on a small app for fun applying the same framework the company used. Ticketfly made a meaningful investment in my career, and also took a significant risk in hiring a new junior engineer. However, it paid off for them — and for me. I stayed with Ticketfly through two acquisitions and was promoted to senior software engineer. With the lack of senior engineers available in the hiring pool, many companies are now hiring junior engineers — often hiring them right out of coding bootcamps — or creating apprenticeship programs within the company. This is a smart strategy to add talent to an engineering team, but while hiring an experienced or senior engineer adds a contributing member to your team, hiring a junior engineer is a long-term investment. If companies rush to hire junior engineers before determining the company has the support system, resources, senior team members willing to mentor new engineers, and a realistic timeline for when a junior engineer will add value to the team — everyone suffers. Eventbrite runs a mentorship program where we match mentees to a mentor based on what they want to learn. We also host weekly Code Labs where senior engineers teach a new topic each week. The Code Lab is a comfortable environment for the junior to ask questions without feeling incompetent. Take away Do you have a knowledgeable engineer willing to take the time to mentor and pair with the new hire? Onboarding and teaching a junior engineer is a considerable responsibility. Managing expectations One of the incredible things about my current company is its focus on jumpstarting the careers of junior engineers. Eventbrite has hired more bootcamp graduates from Hackbright an all women coding bootcamp than any other company out there. Most of the hires are still at the company years later, and are exceptional contributors to the codebase. Take away Before hiring a new junior engineer, think about your timing. Would you have time to mentor this engineer? Pair programming Having a culture of pair programming is a great benefit when hiring a junior engineer. One of the great things for me when I started out my career was that my mentor would pair with me when I got stuck on an issue, but he also encouraged me to go figure things out on my own. We practice driving and navigating pairing at Eventbrite. It helps to keep both members of a pair actively engaged in solving the problem. Take away Try assigning an easy task to the junior engineer to take a stab at it first. If they run into problems, try pairing on the problem. Eventbrite buddies have regular check-ins with new hires to make sure things are running smoothly. Training Eventbrite hosts an incredible training session on with our principal Front-End engineer,. The session walks you through building out an application in React and provides solutions in separate branches if you get stuck so that anyone can keep up with the pace. Most companies tailor their onboarding programs toward engineers with years of experience. This practice can be frustrating to a junior engineer. One of the great things that Eventbrite does to support junior engineers is to provide a buddy just for setting up your dev environment. Another side of it could be online training. Eventbrite provides accounts for all employees. Take away Creating a small repository with tests that your junior engineer needs to get passing can get someone onboarded quickly. Find an interesting conference that offers a workshop. While I was their first junior engineer, they had a strategy, realistic expectations, provided me with a strong support system, and invested in my learning.

Tagged , , , , The Event Creation team at Eventbrite needed a React based image uploader that would provide flexibility while presenting a straightforward user interface. The image uploader components ought to work in a variety of scenarios as reusable parts that could be composed differently as needs arose. Read on to see how we solved this problem. In the past, if you wanted to get a file from your web users, you had to use a. That identifier is then immediately associated with a database record or put into a hidden form field. This new strategy provides tremendous flexibility over traditional upload processes. For example, decoupling file transportation from form submissions enable us to upload directly to third-party storage like Amazon S3 without sending the files through our servers. The tradeoff for this flexibility is complexity; drag-and-drop file uploaders are complex beasts. We also needed our React uploader to be straightforward and usable. Finding a path to provide both flexibility and ease-of-use was no easy task. Identifying Responsibilities Establishing the responsibilities of an uploader seems easy… it uploads, right? If the user drags a file over it, it should indicate this change in state. Either way, our uploader must show a file chooser when the user clicks or taps. It must show a meaningful error to the user so they know to try again or give up. These responsibilities are just a short list, but you get the idea, they can get complicated very quickly. Moreover, while uploading images is our primary use case, there could be a variety of needs for file uploading. So, how can we structure our React Image Uploader to get maximum flexibility and reusability? Separation of Concerns In the following diagram you can see an overview of our intended approach. Instead, they can reuse as much or as little as they need. So we took our list of responsibilities and created a stack of components, ranging from most general at the bottom to most specific at the top. Foundational Components UploaderDropzone This component is the heart of the uploader UI, where action begins. It has no state itself, only knowing how to normalize and react see what I did there? It accepts callbacks as props so it can tell its implementer when things happen. It listens for files to be dragged over it, then invokes a callback. The following is an example of UploaderDropzone using React: Drag a file here! UploaderDropzone has very little opinion about how it looks, and so has only minimal styling. For example, when they occur on deep descendants of the target node. To address this problem the dropzone uses a single transparent div to cover all its descendants. UploaderLayoutManager The UploaderLayoutManager component handles most state transitions and knows which layout should be displayed for each step of the process, while accepting other React Components as props for each step. This allows implementers to think about each step as a separate visual idea without the concern of how and when each transition happens. Supporters of this React component only have to think about which layout should be visible at a given time based on state, not how files are populated or how the layout should look. The LayoutManager itself has little or no styles, and only displays visuals that have been passed as props. This is because the implementing component needs to define the state in which the uploader starts. For example, if the user has previously uploaded an image, we want to show that image when they return to the page. This is also a great place to do validation file type, file size, etc. Supporters of this tool can focus almost entirely on the visual look of the uploader. This component maintains very little logic since state transitions are handled by the UploaderLayoutManager. We can change the visuals fluidly with very little concern about damaging the function of the uploader. We want this ImageUploader component to live in our component library and be decoupled from API specific behavior, so we need to remove that. If file fails validation, return a rejected promise. One part of your application can upload images directly to a third party like Amazon S3 , while another can upload to a local server for a totally different purpose and handling, but using the same visual presentation. And now because all that complexity is compartmentalized into each component, the ImageUploader has a very clean implementation: With this foundation applications can use this same ImageUploader in a variety of ways. New wrappers can be built upon UploadLayoutManager to handle other file types or new layouts. In Closing Imagine image uploaders which were purpose-built for each scenario, but contain only a few simple components made of presentational markup. They can each use the same upload functionality if it makes sense, but with a totally different presentation. Or flip that idea around, using the same uploader visuals but with totally different API interfaces. In what other ways would you use these foundational components? What other uploaders would you build? More often, self-deception is responsible. I would not have purchased the service if I knew this. However, I am not ready to date. I asked if I could talk to the manager and they said this was their policy. If you want to re-build trust and loyalty, admit your mistakes. Solo are other types of tests, but if you and your team want to start testing, unit tests suit you best. It's seems appropriate for SEO and human-memorability.
