rules_nodejs produces several repositories for you to reference.
Bazel represents your workspace as one repository, and code fetched or installed from outside your workspace lives in other repositories.
These are referenced with the @repo// syntax in your BUILD files.
This repository is created by calling the nodejs_repositories function in your WORKSPACE file.
It contains the node, npm, and npx programs.
As always, bazel query is useful for learning about what targets are available.
$ bazel query @nodejs//...
@nodejs//:node
...
You don’t typically need to reference the @nodejs repository from your BUILD files because it’s used behind the scenes to run node and fetch dependencies.
Some ways you can use this:
bazel run @nodejs//:node path/to/program.jsbazel run @nodejs//:npm(Note: for backward-compatibility, the @nodejs repository can also be referenced as @nodejs_host).
