The yarn.lock file should be placed into node_modules

The yarn.lock file should be placed into node_modules.
Or SourceTree or WebStorm will prompt to add it to cvs.
And I metioned a .yarn-integrity file existed in node_modules, and place the yarn.lock into it should be also OK?

Why not committing yarn.lock file? Basically, this will assure to have a deterministic and reproducable build. I am aware of the bad thing, that yarn.lock also stores URLs, which I would like to see parameterized over any env variable.
However, this is the only way to be totally sure, that the build will run on any machine with the same result.

@cnyyk node_modules is typically gitignored. Project config files, like a lock file, are typically at the root of a repo. yarn.lock should be committed, that's the whole point.

You're supposed to commit yarn.lock. See #1067 for more discussion on this.

Got. Thanks so much.
