angular 命令

常用示例

说明

ng is the command-line interface for Angular, a platform for building web applications. It provides tools for creating projects, generating code, building, testing, and deploying Angular applications. The CLI automates common development tasks through schematics - templates that generate boilerplate code for components, services, modules, and other Angular constructs. The generate command supports creating components, directives, pipes, services, classes, guards, interfaces, enums, and modules. Projects are configured through angular.json, which defines build targets, file paths, and environment-specific settings. The CLI supports multiple projects within a single workspace, enabling monorepo-style development. The serve command provides a development server with hot module replacement, automatically rebuilding and refreshing the browser when source files change. Production builds use build --configuration production which enables optimizations like ahead-of-time compilation, tree shaking, and minification.
