@gorilainvest/nx-buf v1.1.3

nx-buf

An Nx plugin for performing codegen from Protobuf/gRPC projects using Buf.

Installation

To install this plugin, run the following command:

npm install @gorilainvest/nx-buf

And add it to the list of plugins in nx.json:

{
  // ...
  "plugins": [
    // ...
    "@gorilainvest/nx-buf"
  ]
}

Features

This plugin assumes that you have a separate Nx project in your workspace that contains your .proto files, as well as buf.yaml and buf.gen.yaml in that project root.

Linting

To enable linting a buf project, use the @gorilainvest/nx-buf:lint executor in that project's project.json:

{
  // ...
  "targets": {
    "lint": {
      "executor": "@gorilainvest/nx-buf:lint"
    }
  }
}

Codegen

To generate source files from a buf project into another project, use the @gorilainvest/nx-buf:generate executor in the destination project:

{
  // ...
  "targets": {
    "proto-gen": {
      "executor": "@gorilainvest/nx-buf:generate",
      "outputs": ["{projectRoot}/{options.copyTo}"],
      "options": {
        "srcProject": "proto",
        "copyFrom": ["gen/*"],
        "copyTo": "src/gen",
        "options": "--include-imports"
      }
    },
    "build": {
      "dependsOn": ["proto-gen"],
      // ...
    }
  }
}

The options are as follows:

• srcProject: the project from where to grab the generated sources after running buf generate.
• copyFrom: a list of glob patterns to copy from that project, relative to its root.
• copyTo: the destination folder, relative to the target project.
• options: (optional) additional command-line arguments to pass to buf generate.

Dependency graph

This plugin will automatically establish a dependency between any project that contain a @gorilainvest/nx-buf:generate target and the respective project specified in options.srcProject.
