Run Tasks in Parallel

If you want to increase the number of processes running tasks to, say, 5 (by default, it is 3), pass the following:

npx nx build myapp --parallel=5

Note, you can also change the default in nx.json, like this:

{% tabs %} {% tab label="Nx >= 17" %}

{
  "parallel": 5
}

{% /tab %} {% tab label="Nx < 17" %}

{
  "tasksRunnerOptions": {
    "default": {
      "runner": "nx/tasks-runners/default",
      "options": {
        "parallel": 5
      }
    }
  }
}

{% /tab %} {% /tabs %}
