jq-web-wasm

This is a fork of jq-web to support Node v18+ and TypeScript.

Usage

1. Install

``bash
npm i jq-web-wasm
# or from Github
npm i github:eGust/jq-web-wasm
# or
yarn add jq-web-wasm
# or
pnpm i jq-web-wasm
`

2. Use with TypeScript

`ts
// demo.ts
import { assert } from 'node:console';
import { promised } from 'jq-web-wasm/jq.wasm';

const demo = async () => {
const foo = await promised.json({ foo: 'bar' }, '.foo');
const baz = JSON.parse(await promised.raw(JSON.stringify({ baz: 'bar' }), '.baz'));
console.debug({ foo, baz });
assert(foo === 'bar', foo is not "bar" (got ${foo}));
assert(baz === 'bar', baz is not "bar" (got ${baz}));
};

demo();
`

`bash
# run it in shell
❯ tsx demo.ts # tsx
{ foo: 'bar', baz: 'bar' }
`

Motivation

Due to Node v18 introduced fetch API, the original jq-web uses fetch to detect whether it's running in a browser env. Unfortunately, this way no longer works since Node v18.

This package simply replaced typeof fetch === "function" with (typeof global !== 'object' && typeof fetch === "function") to get it work. In theory it should work for any version that support WASM. However, Node v14 is almost reaches its EOL, so I put the engine to require Node >= 16.

Compile by yourself

Please check scripts in package.json:

1. run pnpm i to install dependencies.
2. run pnpm copy-wasm-to-dist to copy jq.wasm.wasm to dist/.
3. run pnpm reformat:jq.wasm.js to generate readable dist/reformatted-jq.wasm.js.
4. update dist/reformatted-jq.wasm.js and replace dist/jq.wasm.js with it.
5. run pnpm minify to create dist/jq.wasm.min.js

> Sure you can use npm or yarn` instead.
