Bazel Commands

All these commands assume you are running them from the root of the project.

Build everything

bazel build //...

Build specific thing

bazel build //cmd/cli-demo:cli-demo

Run something

bazel run //cmd/cli-demo:cli-demo

Update BUILD.bazel files

bazel run //:gazelle

Update WORKSPACE file for new dependencies

bazel run //:gazelle -- update-repos -from_file go.mod

Note if you go mod tidy it's always a good idea to update-repos at the same time.

Testing methods

Running CLI commands which were just built is a little awkward as they live in the bazel-bin folder and are buried under a large folder structure. To make this is a little easier you can create a simple symbolic link under the /usr/local/bin folder (which should already be in the PATH) making it easy to rerun the command every build.

sudo ln -s ~/Repos/golang/bazel-bin/cmd/cli-demo/cli-demo_/cli-demo /usr/local/bin/cli-demo

which cli-demo # should return /usr/local/bin/cli-demo

Then you can easily run cli-demo to execute the command after each bazel build \\...

Avoid broke stuff...

bazel build --build_tag_filters=-excluded //...
