felt-rollup

0.1.2 verified Mon Apr 27 auth: no javascript deprecated

Rollup plugin for the Felt web development framework (v0.1.2). This package provides middleware that integrates Rollup bundling into Felt's asset pipeline, processing JavaScript files with custom Rollup plugins (e.g., buble, resolve, commonjs). It targets legacy projects using Felt (unmaintained) and is not recommended for new development; alternatives like Vite or native Rollup are preferred. No recent updates or active maintenance expected.

Quickstart

Shows how to integrate felt-rollup middleware with Express, Felt, and Rollup plugins.

const express = require('express');
const felt = require('felt');
const rollup = require('felt-rollup');
const buble = require('rollup-plugin-buble');
const resolve = require('rollup-plugin-node-resolve');
const commonjs = require('rollup-plugin-commonjs');

const app = express();
app.use(felt({
  src: 'public',
  handlers: {
    '.js': rollup({
      plugins: [
        resolve({ jsnext: true, main: true, browser: true }),
        commonjs(),
        buble()
      ],
      sourceMap: true
    })
  }
}));
app.use(express.static('public'));
app.listen(3000);
