This is a boilerplate for [ScalaJS](https://www.scala-js.org) + [React](https://reactjs.org) apps using [Slinky](https://slinky.dev/).

Most boilerplates and tutorials for ScalaJS out there use [scajajs-bundler](https://scalacenter.github.io/scalajs-bundler/), which wraps [Webpack](https://webpack.js.org) and is probably great, but not for me. I don't like _Webpack_, but would be fine if it worked, however I get very confused about it, get different errors every time I try and I don't like that I don't understand what it is doing.

Apparently all _scalajs-bundler_ does is bundle together the [npm](https://www.npmjs.com) packages into the same file that results from the _ScalaJS_ compilation.
|

|

Here instead we have two files: one is the one that comes from _ScalaJS_, `target/scala-2.13/app-fastopt/main.js` and the other is one that comes from `globals.js` when built with [esbuild](https://esbuild.github.io/), `globals.bundle.js`. These two are included in `index.html`.
|
||
|
|
|
||
|
|
To start building your app, run `yarn start` (or `npm run start`) and it will bundle the dependencies then start watching the Scala files and rebuilding the main app.
|
||
|
|
|

|
|
If you want to add a new _npm_ dependency, modify `globals.js` and restart `yarn start`.
