So I get an error showing a white box and a red box. The white box is inside the red one. What is it telling me? The interior text has gutter of. I have no idea what the problem is. There isn't even a place to drop the question? No tech support? So why not post it as a different question? Regardless of that, I assume you're uploading your own cover in what format?

    In the case of my medically confirmed death, doctors can take out my liver, lungs or heart and give them to someone else, if it helps them. Our Austrian neighbors, however, boast a staggering How the hell is that even possible?

    Simple: In Austria, being an organ donor is the default. Sticking with the default is one of the biases at play in our decision-making, which make relying on common sense unstable.

    Two other, but similar biases are priming and anchoring.

    Non-Obvious Summary

    Priming means exposing you to certain stimuli to influence your later decisions. Therefore, relying on common sense is a bad strategy, especially when making important decisions, for example concerning business strategy. Have you ever considered abandoning predicting altogether and just living, deciding and reacting to the present, based on your own observations? Zara has. The people who work in HR! This is called local knowledge and you should use it whenever you can.

    Every decision has performance implications, and the project would hugely benefit from front-end developers properly communicating performance values to the whole team, so that everybody would feel responsible for it, not just front-end developers.

    Map design decisions against performance budget and the priorities defined in the checklist. Setting Realistic Goals millisecond response time, 60 fps.

    Any longer than that, and the user perceives the app as laggy.

    Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. RAIL , a user-centric performance model.

    Because the browser needs time to paint the new frame to the screen, your code should finish executing before hitting the Be pessimistic in performance expectations, but be optimistic in interface design and use idle time wisely. Obviously, these targets apply to runtime performance, rather than loading performance.

    Although it might be very difficult to achieve, a good ultimate goal would be First Meaningful Paint under 1 second and a Speed Index value under The former is the earliest point after the main content has rendered where there is at least a 5-second window where the page is responsive.

    The latter is the point where the page can be expected to always be responsive to input thanks, Philip Walton! We have two major constraints that effectively shape a reasonable target for speedy delivery of the content on the web. To achieve the goals stated in the first paragraph, we have to consider the critical file size budget for JavaScript.

    Front-End Performance Checklist 2019 [PDF, Apple Pages, MS Word]

    Opinions vary on what that budget should be and it heavily depends on the nature of your project , but a budget of KB JavaScript gzipped already would take up to 1s to parse and compile on an average phone.

    On a middle-class mobile device, that accounts for seconds for Time-To-Interactive. We could also go beyond the bundle size budget though. Tools such as Calibre , SpeedCurve and Bundlesize can help you keep your budgets in check, and can be integrated into your build process. Performance budgets should adapt depending on the network conditions for an average mobile device. Stick to your environment for building, be it Grunt, Gulp, Webpack, Parcel, or a combination of tools.

    Among the build tools, Webpack seems to be the most established one, with literally hundreds of plugins available to optimize the size of your builds. Getting started with Webpack can be tough though. Both of them are great introductions for diving into Webpack. Webpack Fundamentals is a very comprehensive 4h course with Sean Larkin, released by FrontendMasters. Webpack examples has hundreds of ready-to-use Webpack configurations, categorized by topic and purpose.

    Bonus: there is also a Webpack config configurator that generates a basic configuration file. Use progressive enhancement as a default.

    Keeping progressive enhancement as the guiding principle of your front-end architecture and deployment is a safe bet. Design and build the core experience first, and then enhance the experience with advanced features for capable browsers, creating resilient experiences. If your website runs fast on a slow machine with a poor screen in a poor browser on a sub-optimal network, then it will only run faster on a fast machine with a good browser on a decent network.

    Choose a strong performance baseline. With the performance bottlenecks moving away from the server to the client , as developers, we have to consider all of these unknowns in much more detail. The first render tends to warm up a bunch of lazily compiled code, which a larger tree can benefit from when it scales. The second render is basically an emulation of how code reuse on a page affects the performance characteristics as the page grows in complexity.

    Evaluate each framework and each dependency. Now, not every project needs a framework and not every page of a single-page-application needs to load a framework. It might sound obvious but worth stating: some projects can also benefit benefit from removing an existing framework altogether. Inian Parameshwaran has measured performance footprint of top 50 frameworks against First Contentful Paint — the time from navigation to the time when the browser renders the first bit of content from the DOM.

    You could examine your framework candidates and the proposed architecture, and study how most solutions out there perform, e. Baseline performance cost matters. According to a study by Ankur Sethi , "your React application will never load faster than about 1. Your Angular app will always take at least 2. The users of your Vue app will need to wait at least 1 second before they can start using it.

    In exchange, your team gains maintainability and developer efficiency, of course. But this consideration needs to be deliberate. A good starting point is to choose a good default stack for your application. When building a web app, look into the PRPL pattern and application shell architecture. The idea is quite straightforward: Push the minimal code needed to get interactive for the initial route to render quickly, then use service worker for caching and pre-caching resources and then lazy-load routes that you need, asynchronously.

    PRPL stands for Pushing critical resource, Rendering initial route, Pre-caching remaining routes and Lazy-loading remaining routes on demand.

    Have you optimized the performance of your APIs? APIs are communication channels for an application to expose data to internal and third-party applications via so-called endpoints. When designing and building an API , we need a reasonable protocol to enable the communication between the server and third-party requests. Representational State Transfer REST is a well-established, logical choice: it defines a set of constraints that developers follow to make content accessible in a performant, reliable and scalable fashion.

    Non-Obvious Summary, Review PDF

    As with good ol' HTTP requests, when data is retrieved from an API, any delay in server response will propagate to the end user, hence delaying rendering.

    When a resource wants to retrieve some data from an API, it will need to request the data from the corresponding endpoint.

    A component that renders data from several resources, such as an article with comments and author photos in each comment, may need several roundtrips to the server to fetch all the data before it can be rendered.

    Furthermore, the amount of data returned through REST is often more than what is needed to render that component. GraphQL provides a performant solution to these issues.

    Per se, GraphQL is a query language for your API, and a server-side runtime for executing queries by using a type system you define for your data. In addition, because GraphQL is using schema metadata that tells how the data is structured , it can already organize data into the preferred structure, so, for example, with GraphQL, we could remove JavaScript code used for dealing with state management , producing a cleaner application code that runs faster on the client.

    You can achieve good performance without them, but AMP does provide a solid performance framework with a free content delivery network CDN , while Instant Articles will boost your visibility and performance on Facebook. For content-heavy websites that are dealing with a lot of third-party content, these options could potentially help speed up render times dramatically. Unless they don't. AMP is not what makes the biggest difference from a performance perspective.

    Obviously, a presence in a walled garden places developers in a position to produce and maintain a separate version of their content, and in case of Instant Articles and Apple News without actual URLs thanks Addy, Jeremy! Choose your CDN wisely. Depending on how much dynamic data you have, you might be able to "outsource" some part of the content to a static site generator , pushing it to a CDN and serving a static version from it, thus avoiding database requests.

    You could even choose a static-hosting platform based on a CDN, enriching your pages with interactive components as enhancements JAMStack. In fact, some of those generators like Gatsby on top of React are actually website compilers with many automated optimizations provided out of the box.

    As compilers add optimizations over time, the compiled output gets smaller and faster over time. Notice that CDNs can serve and offload dynamic content as well.

    So, restricting your CDN to static assets is not necessary. Double-check whether your CDN performs compression and conversion e.
