angular2-rollup

5.0.0-beta.6.1 verified Mon Apr 27 auth: no javascript

Angular 2 starter using AOT compilation with ngc, Rollup bundling, and Closure Compiler optimization. Version 5.0.0-beta.6.1. Provides CLI commands (ngr) for JIT/dev/prod builds, testing with Jasmine/Karma, e2e with Protractor, SASS/PostCSS stylesheets, and Express server with LiveReload. Build scripts use ShellJS for cross-platform support. Differentiates by focusing on production optimization with Rollup+Closure Compiler and providing a boilerplate for component libraries.

Common errors

error ngr: command not found ↓

cause angular2-rollup not installed globally or not in PATH.

fix

Run: npm install -g angular2-rollup

error Cannot find module 'typescript' ↓

cause Missing TypeScript dependency; scaffold may not install it.

fix

Run: npm install typescript --save-dev

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

cause Required Angular compiler packages are missing.

fix

Run: npm install @angular/compiler-cli @angular/compiler --save-dev

Warnings

deprecated Angular 2 is long deprecated; projects should use Angular 17+. ↓

fix Use a modern Angular CLI project (e.g., @angular/cli) instead.

gotcha CLI commands require global installation; running 'ngr' without global install fails. ↓

fix Install globally: npm install -g angular2-rollup

gotcha Node version must be v6.5.x+; newer Node versions may cause incompatibilities with dependencies. ↓

fix Use Node v6.5.x (or use a version manager like nvm).

gotcha Scaffold command creates files in current directory; running in wrong directory can overwrite files. ↓

fix Create a new directory first: mkdir my-app && cd my-app && ngr scaffold

deprecated Protractor and Karma are outdated; modern Angular uses Cypress or Playwright for e2e and Jest for unit tests. ↓

fix Consider migrating to modern testing tools.

Install

npm install angular2-rollup

yarn add angular2-rollup

pnpm add angular2-rollup

Imports

ngr
wrong
```
npm install angular2-rollup --save-dev
```
correct
```
npm install -g angular2-rollup
```
The cli is installed globally; local install is not typical.
scaffold
wrong
```
ngr --scaffold
```
correct
```
ngr scaffold
```
CLI command is 'ngr scaffold' (no leading dashes), but older docs show --scaffold may also work.
build
wrong
```
ngr build --prod
```
correct
```
ngr build prod
```
Commands are like 'ngr build jit', 'ngr build dev', 'ngr build prod' – not flags.
