This PR adds run-lerna script to allow LERNA_ROOT_PATH to be passed into lerna commands.

The run-lerna script adds the following logic:

  • Set LERNA_ROOT_PATH env var

Fixes #1010

+1 for adding bin/run-lerna.js, it's a decent workaround for lerna/lerna#1343.

-1 for implementing bin/run-env.js, it feels like reinventing a wheel to me. Have you tried cross-env? What are the arguments against cross-env in favor of maintaining our own implementation?

Besides my comment above, please update loopback/build's README to mention the new script(s).

If you are ok with removing isVSCode per my comment above, then the part of this patch adding LERNA_ROOT_PATH only can be landed without further review.

bin/run-lerna.js Outdated
process.env.LERNA_ROOT_PATH = rootPath;
let args = argv.slice(2);

// Force lerna command runs in non-parallel mode for VSCode builds

I am not very happy with this solution, it will significantly slow down builds triggered from VS Code. Can we either leave this part out of this initial pull request?

Here is what I would like us to eventually implement:

  • At minimum, have two VSCode tasks - one for the usual "fast" build that reports broken error paths, anther for a "slow" build that works well with PROBLEMS window.
  • Ideally, we should invoke typescript in parallel via some sort of a tool that can merge the output in a clever way, or perhaps tell Lerna to not print those prefixes.

Either way, I'd like to have the option to run the build in parallel mode, it stays my default mode most of the time.

I misunderstood what you want for VSCode.

Here is what I found out:

I'll remove the VSCode check for now.

I contributed a patch to lerna - lerna/lerna#1352

@raymondfeng
chore: add run-lerna script to run lerna with repo root
7a620b2 
The script sets `LERNA_ROOT_PATH` to the root directory of loopback-next
monorepo and run `lerna` commands. It also detects VSCode and disables
parallel mode.
