feat(core): add commands for debugging cache inputs / outputs by AgentEnder · Pull Request #34414 · nrwl/nx

AgentEnder · 2026-02-11T22:29:20Z

Current Behavior

There's not a great way to troubleshoot or test inputs and outputs configurations on tasks.

Expected Behavior

Adds nx show target to enable users to debug inputs and outputs. It has flags --inputs, --check-input, --outputs, and --check-output to list or test specific file patterns.

Can we make this...

nx show target nx:build
nx show target inputs nx:build
nx show target inputs nx:build --check path/to/blah
nx show target outputs nx:build
nx show target outputs nx:build --check path/to/blah

Important

At least one additional CI pipeline execution has run since the conclusion below was written and it may no longer be applicable.

Nx Cloud is proposing a fix for your failed CI:

These changes complete the deterministic rendering fix for the nx show target command. The previous commit added sorting to renderInputs() but missed the expandInputsForDisplay() function, causing snapshot test failures due to non-deterministic input ordering when named inputs were expanded.

Note

⏳ We are verifying this fix by re-running a subset of the 2 failed tasks that were analyzed.

Sort inputs by category (regular strings → dependency inputs → objects) to avoid locale-dependent ordering of ^ prefix vs letters.

localeCompare produces different orderings for special characters like * vs . across different locales/environments.
