Interactive gRPC API Documentation

</div>

We're like Swagger UI, but for gRPC APIs. Give us a star if you like the project.

Live demo

Live demo is available at https://gendocu-demo.web.app/.

Quickstart

docker run -rm --network host \
  -v <your-proto-root>:/input \
  -v $(pwd)/output:/output \
  gendocu/grpc-docs

Install

Only for node 12+ (you can check your node version with node -v)

npm install --save grpc-docs

yarn add grpc-docs

Usage

You can find all the integration types in example/src/App.tsx file.

You can use this widget standalone or with GenDocu Cloud gRPC CI/CD. Feature comparison is below.

Running example

Clone this project
Go to example directory and use yarn start to run the frontend
In case you want be able to modify the library open the repository root directory in second terminal and run yarn start

Standalone within existing react frontend

Install grpc-docs - instruction in Setup section
Generate json description from protobuf api with project protoc-gen-doc: protoc --doc_out=./ --doc_opt=json,description.json *.proto
Inside your React project create API Reference component - you can see example of usage in example/src/App.tsx

import React from 'react'

import { GRPCSelfGeneratedAPIReference } from 'grpc-docs'

const Example = () => {
  // return <GRPCSelfGeneratedAPIReference file='url-to-json-description-of-api'/>

  // return <GRPCSelfGeneratedAPIReference definition='A json string definition that got generated by protoc'/>

  return <GRPCSelfGeneratedAPIReference file='example-descriptors/description.json'/>
}

[optional] You can also provide the environments and authentication description - add scheme='path-to-scheme-file.yaml'. Use GenDocu Cloud Api Specification Scheme. You can find example file here.

Hosting the generated protoc JSON behind auth.

You can provide a protoc definition as text directly to the <GRPCSelfGeneratedAPIReference /> component. So you should be able to fetch your hosted json with the correct headers and provide it to the compoenent in the definition prop.

import React from 'react'

import { GRPCSelfGeneratedAPIReference } from 'grpc-docs'

const Example = async () => {
  const resp = await fetch('my-company.com/protoc.json')
  const definition = await resp.text()

  return <GRPCSelfGeneratedAPIReference definition={definition}/>
}

With GenDocu

Install grpc-docs - instruction in Setup section
Create a project on Gendocu Cloud
Use component inside your React project

import React from 'react'

import { GRPCGenDocuAPIReference } from 'grpc-docs'

const App = () => {
  //return <GRPCGenDocuAPIReference project='your-gendocu-project' organization='your-organization'/>
  return <GRPCGenDocuAPIReference project='LibraryApp' organization='gendocu'/>
}
export default App;

You can also implement your own backend wrapper - API documentation is available here.

Customize style

To create your own styled documentation change the implementation in style/default - you can find there all the files implementing the UI of documentation. We strongly recommend to create own style directory, like style/my-style instead of overwriting the style/default components.

Troubleshooting

... is not allowed. Add this origin in your documentation settings. You have to add the host in your GenDocu project settings. If the project is not owned by you, ask project owner.
