fix(core): unregister in-process ts transpilers when projectGraph is created #19187

@Cammisuli Cammisuli commented Sep 15, 2023

Current Behavior

When running CI=true we register ts transpilers in the main nx process. Usually this registration happens in the daemon, and has no effect on other processes that get spawned from the main nx process. But when registered in the main process, all child processes get the same registered transpiler.

This causes issues with NX_BATCH_MODE=true with jest for Nx Plugin tests because jest tried to load jest configuration files (which are in .ts), and when reading these files swc will transpile these to a format that is not supported in jest.

Expected Behavior

When we're done reading the workspace files, unregister transpilers so that child processes do not have their require functions patched.

Would the transpiler not just get re-registered when creating the dependencies? It seems like this should be done at the end of createProjectGraphAsync or similar as well.
