Lerna 6: Obsolete Options
Nx and Lerna work together seamlessly in the same workspace.
When Lerna is running tasks with Nx and detects Nx target configuration, Lerna will respect this configuration during
and delegate dependency detection to the Nx task runner.
Nx will run tasks in an order and with a concurrency that it determines appropriate based on the task graph that it creates. For more information, see Nx Mental Model: The Task Graph.
This behavior allows Nx to run tasks in the most efficient way possible, but it also means that some existing options
lerna run become obsolete.
When Nx targets are configured, Lerna will always run tasks in the order it deems is correct based on its knowledge of
project and task dependencies, so
--no-sort have no effect.
Lerna will use the task graph to determine which tasks can be run in parallel and do so automatically, so
has no effect.
If you want to limit the concurrency of tasks, you can still use the concurrency global option to accomplish this.
Lerna 6 will automatically run dependent tasks first when necessary, so
--include-dependencies is obsolete. However,
the flag can still be used to include tasks that are not required (e.g., running the tests of all the dependent
When used with Nx,
--ignore will never cause
lerna run to exclude any tasks that are deemed to be
required task graph.
The effects on the options above will only apply if:
nx.jsonexists in the root with the
"nx"property is found in the package.json of a target package.
Otherwise, they will behave just as they would with Lerna's legacy task runner (if
