ng build
Compiles an Angular app into an output directory named dist/ at the given output path. Must be executed from within a workspace directory.
ng build <project> [options]
ng b <project> [options]
说明
The command can be used to build a project of type "application" or "library". When used to build a library, a different builder is invoked, and only the ts-config, configuration, and watch options are applied. All other options apply only to building applications.
The application builder uses the webpack build tool, with default configuration options specified in the workspace configuration file (angular.json) or with a named alternative configuration. A "production" configuration is created by default when you use the CLI to create the project, and you can use that configuration by specifying the --configuration="production" or the --prod="true" option.
The configuration options generally correspond to the command options. You can override individual configuration defaults by specifying the corresponding options on the command line. The command can accept option names given in either dash-case or camelCase. Note that in the configuration file, you must specify names in camelCase.
Some additional options can only be set through the configuration file, either by direct editing or with the ng config command. These include assets, styles, and scripts objects that provide runtime-global resources to include in the project. Resources in CSS, such as images and fonts, are automatically written and fingerprinted at the root of the output folder.
For further details, see Workspace Configuration.

|---|---|
<project> | The name of the project to build. Can be an application or a library. |
选项
| 选项 | 说明 |
|---|---|
--aot=true|false | Build using Ahead of Time compilation. 默认值： |
--baseHref=baseHref | Base url for the application being built. |
--buildEventLog=buildEventLog | EXPERIMENTAL Output file path for Build Event Protocol events |
--buildOptimizer=true|false | Enables '@angular-devkit/build-optimizer' optimizations when using the 'aot' option. 默认值： |
--commonChunk=true|false | Use a separate bundle containing code used across multiple bundles. 默认值： |
--configuration=configuration | A named build target, as specified in the "configurations" section of angular.json. Each named target is accompanied by a configuration of option defaults for that target. Setting this explicitly overrides the "--prod" flag 别名： -c |
--crossOrigin= | Define the crossorigin attribute setting of elements that provide CORS support. 默认值： |
--deleteOutputPath=true|false | Delete the output path before building. 默认值： |
--deployUrl=deployUrl | URL where files will be deployed. |
--es5BrowserSupport=true|false | Deprecated: This will be determined from the list of supported browsers specified in the 'browserslist' file. Enables conditionally loaded ES2015 polyfills. |
--evalSourceMap=true|false | Deprecated Output in-file eval sourcemaps. 默认值： |
--experimentalRollupPass=true|false | Concatenate modules with Rollup before bundling them with Webpack. 默认值： |
--extractCss=true|false | Extract css from global styles into css files instead of js ones. 默认值： |
--extractLicenses=true|false | Extract all licenses in a separate file. 默认值： |
--forkTypeChecker=true|false | Run the TypeScript type checker in a forked process. 默认值： |
--help= | Shows a help message for this command in the console. 默认值： |
--i18nFile=i18nFile | Deprecated: Use 'locales' object in the project metadata instead. Localization file to use for i18n. |
--i18nFormat=i18nFormat | Deprecated: No longer needed as the format will be determined automatically. Format of the localization file specified with --i18n-file. |
--i18nLocale=i18nLocale | Deprecated: Use 'localize' instead. Locale to use for i18n. |
--i18nMissingTranslation= | How to handle missing translations for i18n. 默认值： |
--index=index | Configures the generation of the application's HTML index. |
--lazyModules | Deprecated: 'SystemJsNgModuleLoader' is deprecated, and this is part of its usage. Use 'import()' syntax instead. List of additional NgModule files that will be lazy loaded. Lazy router modules will be discovered automatically. |
--localize=true|false | |
--main=main | The full path for the main entry point to the app, relative to the current workspace. |
--namedChunks=true|false | Use file name for lazy loaded chunks. 默认值： |
--ngswConfigPath=ngswConfigPath | Path to ngsw-config.json. |
--optimization=true|false | Enables optimization of the build output. |
--outputHashing= | Define the output filename cache-busting hashing mode. 默认值： |
--outputPath=outputPath | The full path for the new output directory, relative to the current workspace. By default, writes output to a folder named dist/ in the current project. |
--poll | Enable and define the file watching poll time period in milliseconds. |
--polyfills=polyfills | The full path for the polyfills file, relative to the current workspace. |
--preserveSymlinks=true|false | Do not use the real path when resolving modules. 默认值： |
--prod=true|false | Shorthand for "--configuration=production". When true, sets the build configuration to the production target. By default, the production target is set up in the workspace configuration such that all builds make use of bundling, limited tree-shaking, and also limited dead code elimination. |
--profile=true|false | Deprecated: Use "NG_BUILD_PROFILING" environment variable instead. Output profile events for Chrome profiler. 默认值： |
--progress=true|false | Log progress to the console while building. |
--rebaseRootRelativeCssUrls=true|false | Deprecated Change root relative URLs in stylesheets to include base HREF and deploy URL. Use only for compatibility and transition. The behavior of this option is non-standard and will be removed in the next major release. 默认值： |
--resourcesOutputPath= | The path where style resources will be placed, relative to outputPath. 默认值： |
--serviceWorker=true|false | Generates a service worker config for production builds. 默认值： |
