# wasm
|
||
|
|
|
||
|
|
The engine of [`../gpx-rs`](../gpx-rs) for the browser: WebAssembly, exposed to the page through
|
||
|
|
`wasm-bindgen`. Each exported function is a thin wrapper over `gpx_engine::api` (see `../gpx-rs/src/api`)
|
||
|
|
that parses what the page sends and turns the result into JS objects (`src/convert.rs`, with
|
||
|
|
`serde-wasm-bindgen`) or typed arrays. The storage in the browser (IndexedDB) is here too, as it
|
||
|
|
is specific to the browser.
|
||
|
|
|
||
|
|
```
|
||
|
|
wasm-pack build --target bundler
|
||
|
|
```
|
||
|
|
|
||
|
|
The website imports the result as `gpx-wasm` (`pkg/`). The functions are tested in Node (it needs
|
||
|
|
`wasm-pack`, which fetches the test runner the first time):
|
||
|
|
|
||
|
|
```
|
||
|
|
wasm-pack test --node
|
||
|
|
```
|
||
|
|
|
||
|
|
`src/ts.rs` declares the TypeScript types of the objects that cross.
