Getting Started ​

pothos-protoc-gen is a Buf plugin that generates TypeScript code for creating a Protobuf-first GraphQL schema using Pothos GraphQL.

This plugin works with protoc-gen-es to transform your Protocol Buffer definitions into a fully-typed GraphQL schema.

Why pothos-protoc-gen? ​

When building GraphQL APIs that work with Protocol Buffers, manually creating GraphQL types that match your Protobuf definitions can be tedious and error-prone. pothos-protoc-gen automates this process by:

  • Maintaining type consistency: Ensures your GraphQL schema accurately reflects your Protobuf definitions
  • Reducing boilerplate: Automatically generates the TypeScript code needed to build your GraphQL schema
  • Improving developer experience: Leverages Pothos GraphQL's type-safety while working with Protocol Buffers
  • Simplifying updates: When your Protobuf definitions change, regenerate your code to keep everything in sync

This approach provides a clean, type-safe bridge between your Protocol Buffer services and GraphQL API, while minimizing manual code maintenance.
