.Harvey

Harvey is a simple transpilled language that I created to help me learn about compliation and web frameworks. The language comes bundled with a inbuilt simple framework which is modelled after react, but is much simpler. It does not need to use the webframe work and can be used just to produce JS to run on a server.

Create Project

    npm init -y
    npm i harvey-language
    npx harvey-language create-app

Run Development Server

This runs a simple express server which will auto refresh on update, and watches files for updates

    npx harvey-language watch

Build For Production

Production does not come with a server, you can make your own using express, or just upload the src folder to a static host.

    npx harvey-language compile

Express server to serve site

// Example Production Server
const express = require('express');
const app = express();
const PORT = 4000;

app.use(express.static('dist'));

app.get('*', (req, res) => {
    res.sendFile('dist/index.html');
});

app.listen(PORT, () => console.log(`Server listening on port: ${PORT}`));
