Babel and TypeScript both can produce ESM modules, but they **fail with transforming references within the source code**
like `new URL("./pool.worker.ts", import.meta.url)`. There exist some Babel plugins, but none of them is stable.
like `new URL("./multithreaded-pool.worker.ts", import.meta.url)`. There exist some Babel plugins, but none of them is stable.
Therefore, we actually need a proper bundler which supports outputting ESM modules.
The only stable solution to this is Parcel. Parcel also has good documentation around the bundling of WebWorkers.

## Web (WebGL, WebGPU)
If you have a browser which already supports a recent version of the WebGPU specification then you can start a
development server using the following commands.
You need to first build the library for WebGL or WebGPU. Optionally, you can also enabled multi-threading support,
which requires that the library is used in a secure environment:
[isSecureContext](https://developer.mozilla.org/en-US/docs/Web/API/isSecureContext)
and [crossOriginIsolated](https://developer.mozilla.org/en-US/docs/Web/API/crossOriginIsolated).
The demo runs this such an environment.
If you have a browser which already supports a recent version of the WebGPU specification then you can build the library
with WebGPU:
```bash
cd web
npm run start
just web-lib build # WebGPU
```
If you want to run maplibre-rs with WebGL which is supported on every major browser, then you have to use the following
command.
If not, then you must enable WebGL support:
```bash
just web-lib build --webgl # WebGL
just web-lib build --webgl --multithreaded # WebGL + multithreaded
```
Instead of building it is also possible to watch for changes. The same flags like with `web-lib build` are supported:
```bash
just web-lib watch --webgl
```
After building the library you can run the demo server:
```bash
just web-lib build
just web-demo start
```
