Tokay (WASM)

July 23, 2025 · View on GitHub

This is the web-assembly package of the Tokay programming language for NPM.

Tokay is a programming language designed for ad-hoc parsing. It is written in Rust, and can be found officially here.

Important

Tokay (WASM) is in an early project state, therefore things on the package as well as the bindings may change! The package is kept synchronous to the current Tokay release version.

Usage

import { run } from 'tokay';

console.log(run("Int * 3", "123 456 789"));
// (369, 1368, 2367)

Althought this crate and repo is called tokay-wasm, the released npm package is called just tokay. This is ensured by the Makefile. Run make pkg and make publish to perform the required steps.

Invoking manual builds:

for bundlers like vite: wasm-pack build --target=bundler --out-name=tokay
for nodejs: wasm-pack build --target=nodejs --out-name=tokay
