Must say I’m quite excited about Snowpack (formerly known as @pika/web, which I covered here) which just got released.
With Snowpack you can build modern web apps (with React, Vue, etc.) without a bundler (like Webpack, Parcel, Rollup). No more waiting for your bundler every time you hit save. Instead, changes are ready in the browser instantly.
You only have to run Snowpack once. By doing so it will generate ES Modules for all of your dependencies, which you can then directly use in the browser.
Dynamic import() introduces a new function-like form of import, which allows one to import on demand. It returns a promise for the module namespace object of the requested module, which is created after fetching, instantiating, and evaluating all of the module’s dependencies, as well as the module itself.
Say you have a lightbox or dialogbox. You could offload its importing to the very moment it is needed:
Stage-3 is the Candidate Stage where the feature is considered complete and only critical changes will happen based on implementation experience. If all goes well the proposal will advance to Stage 4 without any changes, after which it will to become part of the ECMAScript Specification.
