# Angular Workspace Configuration
|
||||
|
||||
A file named `angular.json` at the root level of an Angular [workspace](guide/glossary#workspace) provides workspace-wide and project-specific configuration defaults for build and development tools provided by the Angular CLI.
|
||||
Path values given in the configuration are relative to the root workspace folder.
|
||||
|
||||
## Overall JSON structure
|
||||
|
||||
At the top level of `angular.json`, a few properties configure the workspace, and a `projects` section contains the remaining per-project configuration options.
|
||||
|
||||
* `version`: The configuration-file version.
|
||||
* `newProjectRoot`: Path where new projects are created. Absolute or relative to the workspace folder.
|
||||
* `defaultProject`: Default project name to use in commands, where not provided as an argument. When you use `ng new` to create a new app in a new workspace, that app is the default project for the workspace until you change it here.
|
||||
* `projects` : Contains a subsection for each project (library, app, e2e test app) in the workspace, with the per-project configuration options.
|
||||
|
||||
The initial app that you create with `ng new app_name` is listed under "projects", along with its corresponding end-to-end test app:
|
||||
|
||||
<code-example format="." language="none" linenums="false">
|
||||
projects
|
||||
app_name
|
||||
...
|
||||
app_name-e2e
|
||||
...
|
||||
</code-example>
|
||||
|
||||
Each additional app that you create with `ng generate application` has a corresponding end-to-end test project, with its own configuration section.
|
||||
When you create a library project with `ng generate library`, the library project is also added to the `projects` section.
|
||||
|
||||
<div class="alert is-helpful">
|
||||
|
||||
Note that the `projects` section of the configuration file does not correspond exactly to the workspace file structure.
|
||||
* The initial app created by `ng new` is at the top level of the workspace file structure, along with its e2e app.
|
||||
* Additional apps, e2e apps, and libraries go into a `projects` folder in the workspace.
|
||||
|
||||
For more information, see [Workspace and project file structure](guide/file-structure).
|
||||
|
||||
</div>
|
||||
|
||||
## Project configuration options
|
||||
|
||||
The following top-level configuration properties are available for each project, under `projects:<project_name>`.
|
||||
|
||||
<code-example format="." language="json" linenums="false">
|
||||
"my-v7-app": {
|
||||
"root": "",
|
||||
"sourceRoot": "src",
|
||||
"projectType": "application",
|
||||
"prefix": "app",
|
||||
"schematics": {},
|
||||
"architect": {}
|
||||
}
|
||||
</code-example>
|
||||
|
||||
| PROPERTY | DESCRIPTION |
|
||||
| :-------------- | :---------------------------- |
|
||||
| `root` | The root folder for this project's files, relative to the workspace folder. Empty for the initial app, which resides at the top level of the workspace. |
|
||||
| `sourceRoot` | The root folder for this project's source files. |
|
||||
| `projectType` | One of "application" or "library". An application can run independently in a browser, while a library cannot. Both an app and its e2e test app are of type "application".|
|
||||
| `prefix` | A string that Angular prepends to generated selectors. Can be customized to identify an app or feature area. |
|
||||
| `schematics` | An object containing schematics that customize CLI commands for this project. |
|
||||
| `architect` | An object containing configuration defaults for Architect builder targets for this project. |
|
||||
|
||||
## Project tool configuration options
|
||||
|
||||
Architect is the tool that the CLI uses to perform complex tasks such as compilation and test running, according to provided configurations. The `architect` section contains a set of Architect *targets*. Many of the targets correspond to the CLI commands that run them. Some additional predefined targets can be run using the `ng run` command, and you can define your own targets.
|
||||
|
||||
Each target object specifies the `builder` for that target, which is the npm package for the tool that Architect runs. In addition, each target has an `options` section that configure default options for the target, and a `configurations` section that names and specifies alternative configurations for the target. See the example in [Build target](#build-target) below.
|
||||
|
||||
<code-example format="." language="json" linenums="false">
|
||||
"architect": {
|
||||
"build": { },
|
||||
"serve": { },
|
||||
"e2e" : { },
|
||||
"test": { },
|
||||
"lint": { },
|
||||
"extract-i18n": { },
|
||||
"server": { },
|
||||
"app-shell": { }
|
||||
}
|
||||
</code-example>
|
||||
|
||||
* The `architect/build` section configures defaults for options of the `ng build` command. See [Build target]{#build-target} below for more information.
|
||||
|
||||
* The `architect/serve` section overrides build defaults and supplies additional serve defaults for the `ng serve` command. In addition to the options available for the `ng build` command, it adds options related to serving the app.
|
||||
|
||||
* The `architect/e2e` section overrides build-option defaults for building end-to-end testing apps using the `ng e2e` command.
|
||||
|
||||
* The `architect/test` section overrides build-option defaults for test builds and supplies additional test-running defaults for the `ng test` command.
|
||||
|
||||
* The `architect/lint` section configures defaults for options of the `ng lint` command, which performs code analysis on project source files. The default linting tool for Angular is [TSLint](https://palantir.github.io/tslint/).
|
||||
|
||||
* The `architect/extract-i18n` section configures defaults for options of the `ng-xi18n` tool used by the `ng xi18n` command, which extracts marked message strings from source code and outputs translation files.
|
||||
|
||||
* The `architect/server` section configures defaults for creating a Universal app with server-side rendering, using the `ng run <project>:server` command.
|
||||
|
||||
* The `architect/app-shell` section configures defaults for creating an app shell for a progressive web app (PWA), using the `ng run <project>:app-shell` command.
|
||||
|
||||
In general, the options for which you can configure defaults correspond to the command options listed in the [CLI reference page](cli) for each command.
|
||||
Note that all options in the configuration file must use [camelCase](guide/glossary#case-conventions), rather than dash-case.
|
||||
|
||||
{@a build-target}
|
||||
|
||||
## Build target
|
||||
|
||||
The `architect/build` section configures defaults for options of the `ng build` command. It has the following top-level properties.
|
||||
|
||||
| PROPERTY | DESCRIPTION |
|
||||
| :-------------- | :---------------------------- |
|
||||
| `builder` | The npm package for the build tool used to create this target. The default is `@angular-devkit/build-angular:browser`, which uses the [webpack](https://webpack.js.org/) package bundler. |
|
||||
| `options` | This section contains defaults for build options, used when no named alternative configuration is specified. See [Default build options](#build-props) below. |
|
||||
| `configurations`| This section defines and names alternative configurations for different intended destinations. It contains a section for each named configuration, which sets the default options for that intended environment. See [Alternate build configurations](#build-configs) below. |
|
||||
|
||||
{@a build-configs}
|
||||
|
||||
### Alternate build configurations
|
||||
|
||||
By default, a `production` configuration is defined, and the `ng build` command has `--prod` option that builds using this configuration. The `production` configuration sets defaults that optimize the app in a number of ways, such bundling files, minimizing excess whitespace, removing comments and dead code, and rewriting code to use short, cryptic names ("minification").
|
||||
|
||||
You can define and name additional alternate configurations (such as `stage`, for instance) appropriate to your development process. Some examples of different build configurations are `stable`, `archive` and `next` used by AIO itself, and the individual locale-specific configurations required for building localized versions of an app. For details, see [Internationalization (i18n)](guide/i18n#merge-aot).
|
||||
|
||||
{@a build-props}
|
||||
|
||||
### Additional build and test options
|
||||
|
||||
The configurable options for a default or targeted build generally correspond to the options available for the [`ng build`](cli/build), [`ng serve`](cli/serve), and [`ng test`](cli/test) commands. For details of those options and their possible values, see the [CLI Reference](cli).
|
||||
|
||||
Some additional options (listed below) can only be set through the configuration file, either by direct editing or with the `ng config` command.
|
||||
|
||||
| OPTIONS PROPERTIES | DESCRIPTION |
|
||||
| :------------------------- | :---------------------------- |
|
||||
| `fileReplacements` | An object containing files and their compile-time replacements. |
|
||||
| `stylePreprocessorOptions` | An object containing option-value pairs to pass to style preprocessors. |
|
||||
| `assets` | An object containing paths to static assets to add to the global context of the project. The default paths point to the project's icon file and its `assets` folder. |
|
||||
| `styles` | An object containing style files to add to the global context of the project. Angular CLI supports CSS imports and all major CSS preprocessors: [sass/scss](http://sass-lang.com/), [less](http://lesscss.org/), and [stylus](http://stylus-lang.com/). |
|
||||
| `scripts` | An object containing JavaScript script files to add to the global context of the project. The scripts are loaded exactly as if you had added them in a `<script>` tag inside `index.html`. |
|
||||
| `budgets` | Default size-budget type and threshholds for all or parts of your app. You can configure the builder to report a warning or an error when the output reaches or exceeds a threshold size. See [Configure size budgets](guide/build#configure-size-budgets). (Not available in `test` section.) |
