rg-rollup

0.1.8 verified Mon Apr 27 auth: no javascript deprecated

A Gulp plugin for Rollup that provides clean, minified builds via simple configuration. Current stable version is 0.1.8, with low release cadence (last update 2018). It wraps Rollup and common plugins (e.g., babel, uglify) for Gulp-based workflows. Differentiator: minimal configuration compared to manual Rollup setup, but outdated and not actively maintained.

Common errors

error TypeError: rgRollup is not a function ↓

cause Importing { rgRollup } instead of default import.

fix

Use: import rgRollup from 'rg-rollup';

error Error: Cannot find module 'rg-rollup' ↓

cause Package not installed or misspelled name.

fix

npm install rg-rollup --save-dev

Warnings

deprecated Package is no longer maintained. Last update was in 2018. ↓

fix Migrate to modern alternatives: use rollup directly or @rollup/plugin-gulp.

breaking rg-rollup is ESM-only. Cannot be required() in CommonJS modules without dynamic import. ↓

fix Use import syntax; if on Node <13.2, use esm package or upgrade Node.

gotcha Plugin configuration expects nested object under 'plugins' key, not array of Rollup plugins. ↓

fix Use format shown in quickstart, not Rollup's official plugin array format.

Install

npm install rg-rollup

yarn add rg-rollup

pnpm add rg-rollup

Imports

default

wrong

const rgRollup = require('rg-rollup');

correct

import rgRollup from 'rg-rollup';

ESM default import. No CJS exports provided.

rgRollup
wrong
```
import { rgRollup } from 'rg-rollup';
```
correct
```
import rgRollup from 'rg-rollup';
```
Package exports a default function, not named export. Wrong import will result in undefined.

gulp

wrong

var gulp = require('gulp');
var rg = require('rg-rollup');

correct

import gulp from 'gulp';
import rgRollup from 'rg-rollup';

Both gulp and rg-rollup are ESM-only. Mixing require() with import may cause errors if project uses ESM.

Quickstart

Shows a basic Gulp task using rg-rollup to bundle and minify a JavaScript file, assuming ESM imports.

import gulp from 'gulp';
import rgRollup from 'rg-rollup';

gulp.task('build', function() {
  return gulp.src('src/index.js')
    .pipe(rgRollup({
      format: 'iife',
      plugins: {
        babel: {
          presets: ['@babel/preset-env']
        },
        uglify: {}
      }
    }))
    .pipe(gulp.dest('dist'));
});
