## README

# @bufbuild/protoplugin

This package helps you create your own code generator plugin using the
Protobuf-ES plugin framework.

**Protobuf-ES** is a complete implementation of [Protocol Buffers](https://protobuf.dev) in TypeScript, suitable for web browsers, Node.js, Deno, and Bun.

In addition to a full Protobuf runtime library, it provides the [`protoc-gen-es`](https://www.npmjs.com/package/@bufbuild/protoc-gen-es)
code generator, which uses a plugin framework to generate base types from
your Protobuf schema. It is fully compatible with both `buf` and `protoc` compilers.

And now, you can write your own **Protobuf-ES** compatible plugins using this same
plugin framework with the `@bufbuild/protoplugin` package.

With `@bufbuild/protoplugin`, you can generate your own TypeScript code tailored
to your project or needs. You also have various options for producing
JavaScript and TypeScript declaration files:

- Exercise full control by writing your own JavaScript and declaration file
  generators in addition to TypeScript.

- Generate TypeScript files only and let the framework generate JavaScript and
  declaration files automatically using our internal TypeScript compiler.

- Generate TypeScript files only and bring your own TypeScript compiler, using
  it to generate JavaScript and declaration files with your own version of
  TypeScript and your own compiler options.

With `@bufbuild/protoplugin`, you have all the tools at your disposal to produce
ECMAScript-compliant code.
