Weekly Platform News: Apple Deploys Web Components, Progressive HTML Rendering, Self-Hosting Critical Resources
In this week’s roundup, Apple gets into web components, how Instagram is insta-loading scripts, and some food for thought for self-hosting critical resources.
Apple deploys web components built using Stencil
that are built using Stencil, a web component compiler.
Stencil is a build-time tool that generates standard web components with minimal overhead, while providing core features such as templating, state management, and routing, as well as performance features such as code-splitting and lazy-loading.
Apple just deployed into production nearly 50 web components powering a major app they have a significant amount of revenue and strategic value riding on. You can’t say that “no one uses web components” or they are “solving problems that don‘t exist or have been solved better in user land” with a straight face anymore.

Instagram makes use of chunked transfer encoding and progressive HTML rendering
Instagram’s website uses HTTP chunked transfer encoding to stream the contents of the HTML document to the browser as each part of the page is generated on the server.
We can flush the HTML
to the browser almost immediately … This allows the browser to start downloading scripts and stylesheets while the server is busy generating the dynamic data in the rest of the page.
They also use this technique to flush JSON data to the page in
elements. The client script waits for this data (using
Promise) instead of requesting it via XHR.

Consider self-hosting your critical resources
One section of University of Notre Dame’s website used to load jQuery from Google’s CDN, which could result in very long loading times (100+ seconds) when visiting the site from China. They’ve resolved the issue by self-hosting jQuery instead.
