npm install rexprsOr with other package managers:
# Using yarn yarn add rexprs # Using pnpm pnpm add rexprs # Using bun bun add rexprsCreate your first rexprs server:
const { Rexprs } = require('rexprs'); const app = new Rexprs(); app.get('/', (req, res) => { res.json({ message: 'Hello from rexprs!' }); }); app.listen(3000, () => { console.log('Server running on http://localhost:3000'); });Want more examples?
