Advanced tools
WASM Arrow 
This package compiles the Rust library of Apache Arrow to WebAssembly. This might be a viable alternative to the pure JavaScript library. Right now, this library is incomplete and the API will change so we recommend using JavaScript library.
You can try this library in Observable at https://observablehq.com/@domoritz/apache-arrow-in-webassembly.
Documentation
Coming later. The API is somewhat similar to the Rust version (https://docs.rs/arrow/3.0.0/arrow/) although there are some differences to make the API more familiar to JavaScript users.
Building and testing
Node
Run with wasm-pack build --target nodejs && node example/flights.js.
To use a debug build, run wasm-pack build --target nodejs --dev && node example/flights.js.
Browser
Build with wasm-pack build --target web. Then run python3 -m http.server and open http://localhost:8000/examples/.
Publishing
Run npm publish to build a bundle and release it to NPM.
Linting
Run cargo fmt && cargo clippy before committing.
Check file size
We can check how large the WASM file is after compression (which every web server probably does).
gzip -9 <pkg//arrow_wasm_bg.wasm | wc -c
