Understanding Angular CLI Output: A Developer's Guide to `ng version`

Angular CLI: Understanding ng version Output (Angular 19.2) The ng version command is one of the first diagnostics any Angular developer should run. It reveals detailed information about the Angular framework version, CLI tools, and the Node/npm environment installed locally. Here’s a breakdown of a sample output and what each section means for you as a developer: Angular CLI: 19.2.8 Node: 22.14.0 Package Manager: npm 11.2.0 OS: win32 x64 Angular: 19.2.7 ... common, compiler, compiler-cli, core, forms ... platform-browser, platform-browser-dynamic, router Package Version --------------------------------------------------------- @angular-devkit/architect 0.1902.8 @angular-devkit/build-angular 17.3.16 @angular-devkit/core 19.2.8 @angular-devkit/schematics 19.2.8 @angular/cli 19.2.8 @schematics/angular 19.2.8 rxjs 7.8.2 typescript 5.7.3 zone.js 0.15.0 CLI Header Block Angular CLI: 19.2.8 The version of the Angular CLI (Command Line Interface) globally installed or running in the local workspace. It defines what commands are available (ng generate, ng build, etc.) and aligns with the core Angular framework. Node: 22.14.0 The Node.js runtime version used. Angular 19 supports Node 18 and above. Newer versions improve performance, compatibility with npm, and ECMAScript features. Package Manager: npm 11.2.0 This tells you which package manager is being used and its version. Angular supports npm, yarn, or pnpm. npm 11 is the latest and works well with modern dependency trees and workspaces. OS: win32 x64 Your operating system and architecture (in this case, 64-bit Windows). Angular Core Packages Angular: 19.2.7 The version of the main Angular packages in your project. Following that, these core packages are grouped: ... common, compiler, compiler-cli, core, forms ... platform-browser, platform-browser-dynamic, router Package Purpose @angular/core Core framework functionality @angular/common Common directives like NgIf, NgFor, pipes, etc. @angular/forms Template-driven and reactive forms support @angular/compiler Compiles HTML templates into JS @angular/platform-browser Browser rendering setup @angular/router Routing module for SPA navigation @angular/compiler-cli Required for AoT (Ahead-of-Time) compilation @angular/platform-browser-dynamic Used during development for JIT compilation Tooling Packages @angular-devkit/* The DevKit is Angular’s underlying build and project configuration infrastructure: Package Role @angular-devkit/architect Defines how projects are built/tested @angular-devkit/build-angular Implements the build process (Webpack/Vite bridge) @angular-devkit/core Utilities shared across the devkit packages @angular-devkit/schematics Enables code generation via ng generate @angular/cli This package provides the core command-line interface functionality. @schematics/angular Contains schematics (code blueprints) for Angular CLI like components, services, pipes. Runtime & Compiler Tools rxjs: 7.8.2 Reactive Extensions for JavaScript. Angular relies heavily on RxJS for reactive forms, HTTP calls, and event handling. typescript: 5.7.3 The version of TypeScript used to compile your code. Angular 19 supports up to TypeScript 5.7. zone.js: 0.15.0 Angular uses zone.js for change detection. It patches async APIs like setTimeout, Promise, and DOM events. Summary Table Category Tool Purpose Angular Framework @angular/core App logic + DI Compiler @angular/compiler-cli AoT, Ivy, SSR CLI Tools @angular/cli Project scaffolding Build Tools build-angular Webpack/Vite builder Reactive Streams rxjs Observables, Streams Language Support typescript Type-safe JS Zone Handling zone.js Auto change detection
