angular-rollup

2.0.5 verified Mon Apr 27 auth: no javascript deprecated

CLI tool for building Angular applications with Rollup and Closure Compiler, extending @angular/cli. Version 2.0.5 (last release) targets Angular 2+ projects, offering optimized production builds via Closure Compiler or Rollup. Key differentiators include integration with @angular/cli, Angular Package Format library builds, and an Express server. Low release cadence; effectively replaced by Angular CLI's built-in optimization and Ivy. Suitable for legacy Angular builds needing minimal bundle sizes.

Common errors

error Error: Cannot find module '@angular/cli' ↓

cause @angular/cli not installed globally.

fix

Run: npm install -g @angular/cli

error 'ngr' is not recognized as an internal or external command ↓

cause angular-rollup not installed globally or not in PATH.

fix

Run: npm install -g angular-rollup. On Windows, restart terminal after install.

error Error: Java not found. Please install Java JDK 8 or higher. ↓

cause Java runtime missing for Closure Compiler.

fix

Install Java JDK 8+ and ensure java is in PATH.

Warnings

gotcha Requires Java JDK 8+ installed on system for Closure Compiler. Missing Java leads to obscure errors. ↓

fix Install Java JDK from https://www.oracle.com/java/technologies/javase/jdk8-downloads.html

deprecated Package is unmaintained; last release 2018. May not work with Angular versions >5 or Node >8. ↓

fix Migrate to @angular/cli with Angular CLI's production build (--prod) which includes optimization.

gotcha Global install required; 'ngr' command will not be found if @angular/cli is not also installed globally. ↓

fix Ensure @angular/cli is globally installed alongside angular-rollup.

gotcha Build command 'ngr build prod' may fail if environment.ts is not properly configured or missing. ↓

fix Ensure environment files exist in src/environments/ or use --env to specify path.
