echo

Echo

A minimal but complete example of using buf with bazel via rules_buf.

Generation

We generate the files using buf directly, this lets us use remote plugins and managed mode. We can do so from within bazel:

bazel run @rules_buf_toolchains//:buf -- generate

Everytime we generate the files we can run, gazelle to auto generate the BUILD files:

bazel run //:gazelle

This will generate the language rules based on the configured gazelle plugins.

Running the server

The server can be started using bazel run //cmd/echo:echo and we can use buf curl to test:

buf curl http://localhost:8080/echo.v1.EchoService/Echo --schema
