Provides a Javascript wrapper for some of the high-level functionality provided by schnorrkel.

npm install @substrate/schnorrkel-js

The functions exposed via wasm are explained here(rust) or [here(js)]. You can clone the repo and run the following to see the details:

cargo docs --open 

Current experimental setup is created using wasm-pack and webpack/node/npm. Make sure to have both of them, alongside the latest nightly version of Rust installed.

In the root of the project run:

wasm-pack build --target browser

A directory named pkg should be created. Then:

cd pkg
npm link 

This creates a local binding to npm, instructing it to use this folder whenever schnorrkel-js was imported as an npm module using require() or import.

Next, create head to the provided www folder (experimental test folder created via npm: npm init wasm-app www) and:

# Run just once
npm link schnorrkel-js
npm install
npm run start

The current index.js does absolutely nothing. It just binds the compiled wasm blob as a parsed object to the window object so that it can be easily tested in the console.

import * as schnorrkel from 'schnorrkel-js'
window.schnorrkel = schnorrkel

To make any further changes, given that the linking with npm link is correct, just re-compile with wasm-pack build and let the npm run start be running in a separate process. It should automatically reload.

Run the tests in Node.Js environment via

wasm-pack test --node 

or to run them directly in the browser:

add this line to the tests module in lib.rs

wasm_bindgen_test_configure!(run_in_browser);

Then

wasm-pack test --chrome
