# Step 11: Build Affected Projects
|
|
|
|
## Build Affected Apps
|
|
|
|
**Once again, make a change to `libs/ui/src/lib/todos/todos.tsx`:**
|
|
|
|
```typescript jsx
|
|
{
|
|
props.todos.map(t => <li className={'todo'}>{t.title} !!</li>);
|
|
}
|
|
```
|
|
|
|
**Run `npm run affected:build`**
|
|
|
|
Nx will rebuild `todos` app. Why didn't it rebuild `ui`?
|
|
|
|
By default, Nx only builds libraries in the context of an application.
|
|
|
|
## Affected:\*
|
|
|
|
You can run any target against the affected projects in the graph like this:
|
|
|
|
```bash
|
|
# The following are equivalent
|
|
npm run affected -- --target=build
|
|
npm run affected:build
|
|
```
|
|
|
|
!!!!!
|
|
Run "npm run affected -- --target=invalid --base=master". What do you see?
|
|
!!!!!
|
|
No projects to run invalid
|
|
An error message saying that the "invalid" target is invalid
|
