Overview

Organize OpenRPC doc into files and directories and compile a complete OpenRPC document.

Directory structure

📂 openrpc/  
├── 📂 components/  
|   └─── 📂 schemas/  
│        └─── 📄 jointPosition.json  
│───📄 info.json  
└───📂 methods/  
    └── 📂 tags/  
         └── 📂 motion/  
              └── 📄 getJointPosition.json  

Example Info file

./info.json

{
    "version": "0.1.0",
    "title": "Motion Controller API"
}

Example Schema File

./components/schemas/jointPosition.json

{
    "type": "object",
    "properties": {
        "jointIndex": {
            "type": "integer"
        },
        "position": {
            "type": "integer"
        }
    }
}

Example Method File

Note, by placing a method file inside a tags subdirectory, the name of the subdirectory will be assigned as a tag for the method.

./methods/tags/motion/getJointPosition.json

{
    "name": "getPosition",
    "description": "Get current joint positions",
    "params": [],
    "result": {
        "name": "jointPositions",
        "description": "updated joint positions",
        "schema": {
            "type": "array",
            "items": {
                "$ref": "#components/schemas/jointPosition"
            }
        }
    },
    "examples": [
        {
            "name": "getPosition",
            "params": [],
            "result": {
                "name": "jointPositions",
                "value": [
                    {
                        "jointIndex": 1,
                        "position": 393
                    },
                    {
                        "jointIndex": 5,
                        "position": 1829
                    }
                ]
            }
        }
    ]
}

Install

npm install open-rpc-compiler --no-save

Compile into a single openrpc.json document

open-rpc-compile > openrpc.json
