run-wasm
run-wasm is an easy to use tool for running WASM based code executions in the browser.
Brought to you by Slip and our amazing OSS contributors.
Install
npm
npm i @run-wasm/run-wasm
yarn
yarn add @run-wasm/run-wasm
Usage - Python
After installing run-wasm you'll need to import the run-wasm python package
Install run-wasm python package
npm i @run-wasm/python
yarn
yarn add @run-wasm/python
@run-wasm/python
uses Pyodide to execute Python. We recommend using the latest version of Pyodide and bringing it into your project via a script.
import React, { useEffect, useState, useRef } from 'react'
import { createPythonClient } from '@run-wasm/python'
import Script from 'next/script'
import CodeRunnerUI from '../components/CodeRunnerUI'
declare global {

Goal of the project
The goal of this project is to build an easy way to execute various programming languages in the browser via WebAssembly.
People should be able to use this project to embed executable code snippets on their websites easily!
We're building this as a new component to be used inside the Slip authoring tool.
