## wasmtest
21+
22+
Library crate to verify that various DataFusion crates compile successfully to the `wasm32-unknown-unknown` target with wasm-pack.
23+
24+
Some of DataFusion's downstream projects compile to WASM to run in the browser. Doing so requires special care that certain library dependencies are not included in DataFusion.
25+
26+
## Setup
27+
28+
First, [install wasm-pack](https://rustwasm.github.io/wasm-pack/installer/)
29+
30+
Then use wasm-pack to compile the crate from within this directory
31+
32+
```
33+
wasm-pack build
34+
```
35+
36+
## Try it out
37+
38+
The `datafusion-wasm-app` directory contains a simple app (created with [`create-wasm-app`](https://github.com/rustwasm/create-wasm-app) and then manually updated to WebPack 5) that invokes DataFusion and writes results to the browser console.
39+
40+
From within the `datafusion/wasmtest/datafusion-wasm-app` directory:
41+
42+
```
43+
npm install
44+
npm run start
45+
```
46+
47+
Then open http://localhost:8080/ in a web browser and check the console to see the results of using various DataFusion crates.
48+
49+
**Note:** In GitHub Actions we test the compilation with `wasm-build`, but we don't currently invoke `datafusion-wasm-app`. In the future we may want to test the behavior of the WASM build using [`wasm-pack test`](https://rustwasm.github.io/wasm-pack/book/tutorials/npm-browser-packages/testing-your-project.html).
50+
51+
## Compatibility
52+
53+
The following DataFusion crates are verified to work in a wasm-pack environment using the default `wasm32-unknown-unknown` target:
54+
55+
- `datafusion-common` with default-features disabled to remove the `parquet` dependency (see below)
56+
- `datafusion-expr`
57+
- `datafusion-optimizer`
58+
- `datafusion-physical-expr`
59+
- `datafusion-sql`
60+
61+
The difficulty with getting the remaining DataFusion crates compiled to WASM is that they have non-optional dependencies on the [`parquet`](https://docs.rs/crate/parquet/) crate with its default features enabled. Several of the default parquet crate features require native dependencies that are not compatible with WASM, in particular the `lz4` and `zstd` features. If we can arrange our feature flags to make it possible to depend on parquet with these features disabled, then it should be possible to compile the core `datafusion` crate to WASM as well.

## About
22+
23+
This template is designed for depending on NPM packages that contain
24+
Rust-generated WebAssembly and using them to create a Website.
25+
26+
- Want to create an NPM package with Rust and WebAssembly? [Check out
27+
`wasm-pack-template`.](https://github.com/rustwasm/wasm-pack-template)
28+
- Want to make a monorepo-style Website without publishing to NPM? Check out
29+
[`rust-webpack-template`](https://github.com/rustwasm/rust-webpack-template)
30+
and/or
31+
[`rust-parcel-template`](https://github.com/rustwasm/rust-parcel-template).
32+
33+
## 🚴 Usage
34+
35+
```
36+
npm init wasm-app
37+
```
38+
39+
## 🔋 Batteries Included
40+
41+
- `.gitignore`: ignores `node_modules`
42+
- `LICENSE-APACHE` and `LICENSE-MIT`: most Rust projects are licensed this way, so these are included for you
43+
- `README.md`: the file you are reading now!
44+
- `index.html`: a bare bones html document that includes the webpack bundle
45+
- `index.js`: example js file with a comment showing how to import and use a wasm pkg
46+
- `package.json` and `package-lock.json`:
47+
- pulls in devDependencies for using webpack:
48+
- [`webpack`](https://www.npmjs.com/package/webpack)
49+
- [`webpack-cli`](https://www.npmjs.com/package/webpack-cli)
50+
- [`webpack-dev-server`](https://www.npmjs.com/package/webpack-dev-server)
51+
- defines a `start` script to run `webpack-dev-server`
52+
- `webpack.config.js`: configuration file for bundling your js with webpack
