# Angular Monorepo Tutorial - 3: Task-Running
|
|
|
|
Common tasks include:
|
|
|
|
- Building an application
|
|
- Serving a local web server with the built project
|
|
- Running your unit tests
|
|
- Linting your code
|
|
- Running e2e tests
|
|
|
|
When you ran your generators in Part 1, you already set up these more common tasks for each project.
|
|
|
|
## Defining Targets
|
|
|
|
Here's the `project.json` file for your `common-ui` project:
|
|
|
|
```json {% fileName="libs/common-ui/project.json" %}
|
|
{
|
|
"name": "common-ui",
|
|
"$schema": "../../node_modules/nx/schemas/project-schema.json",
|
|
"projectType": "library",
|
|
"sourceRoot": "libs/common-ui/src",
|
|
"prefix": "myorg",
|
|
"targets": {
|
|
"test": {
|
|
"executor": "@nrwl/jest:jest",
|
|
"outputs": ["{workspaceRoot}/coverage/{projectRoot}"],
|
|
"options": {
|
|
"jestConfig": "libs/common-ui/jest.config.ts",
|
|
"passWithNoTests": true
|
|
}
|
|
},
|
|
"lint": {
|
|
"executor": "@nrwl/linter:eslint",
|
|
"options": {
|
|
"lintFilePatterns": [
|
|
"libs/common-ui/**/*.ts",
|
|
"libs/common-ui/**/*.html"
|
|
]
|
|
}
|
|
}
|
|
},
|
|
"tags": []
|
|
}
|
|
```
|
|
|
|
You can see that two targets are defined here: `test` and `lint`.
|
|
|
|
The properties inside each of these targets is defined as follows:
|
|
|
|
- `executor` - which Nx executor to run. The syntax here is: `<plugin name>:<executor name>`
|
|
- `outputs` - this is an array of files that would be created by running this target. (This informs Nx on what to save for it's caching mechanisms you'll learn about in [4 - Workspace Optimizations](/angular-tutorial/4-workspace-optimization)).
|
|
- `options` - this is an object defining which executor options to use for the given target. Every Nx executor allows for options as a way to parameterize it's functionality.
|
|
|
|
## Running Tasks
|
|
|
|
|
|
|
|
Run the `test` target for your `common-ui` project:
|
|
|
|
```{% command="npx nx test common-ui" path="~/myorg" %}
|
|
|
|
> nx run common-ui:test
|
|
|
|
PASS common-ui libs/common-ui/src/lib/banner/banner.component.spec.ts
|
|
BannerComponent

|
|
|
|
```
|
|
|
|
Next, run a lint check on your `common-ui` project:
|
|
|
|
```{% command="npx nx lint common-ui" path="~/myorg" %}
|
|
|
|
> nx run common-ui:lint
|
|
|
|
|
|
Linting "common-ui"...
|
|
|
|
All files pass linting.
|
|
|
