Currently this uses the walrus rust crate to parse a custom section of a wasm binary.
not published on NPM yet, so install as GH dep.
With npm:
npm i -S wasm-walrus-tools@AhaLabs/wasm-walrus-tools#v1.0.0
With yarn:
yarn add wasm-walrus-tools@AhaLabs/wasm-walrus-tools#v1.0.0
Then use it in your app:
import { readCustomSection } from 'wasm-walrus-tools'
// Now, given a `wasm` variable that contains a Wasm binary with a custom
// section called 'json':
console.log(readCustomSection(wasm, 'json'))
