Step 11: Build Affected Projects

Build Affected Apps

Once again, make a change to libs/ui/src/lib/ui.ts:

this.innerHTML = `<ul>${this._todos
  .map(t => `<li class="todo">${t.title} !!!</li>`)
  .join('')}</ul>`;

Run nx 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:

# The following are equivalent
nx affected --target=build
nx affected:build

!!!!! Run "nx affected --target=invalid --base=master". What do you see? !!!!! No affected projects to run target "invalid" on An error message saying that the "invalid" target is invalid
