π Under the Wave
A dev server that relies on ECMAScript Modules. π§ WIP π§.
How it works
The idea is to use JavaScript modules, that were introduced in ECMAScript 2015 Language Specification and already implemented by major browsers. Using JavaScript modules we can skip a bundling step, which combines all dependant javascript files into a single one that we can run in the browser, and let browser to load all the dependant files itself on its own.
As a benefit:
- Get feedback earlier, since we don't need to wait for server to prepare initial chunk or to update existing one.
- Spend less time on a proper tooling setup.
Concerns:
- Browser will make way more network requests to load a page. However, it be addressed by HTTP/2.
- Existing packages still may use CommonJS modules, thus it takes additional effort to convert them. Good news, we do it for you π
Try it yourself
Install package:
npm install under-the-wave
Create index.html
and use <script type=module src='..'></script>
to embed modules. Use import
and export
keywords to declare additional dependencies and module's exports inside of module.
Start server:
