ramldt2jsonschema

This repository contains a node implementation that converts a RAML data type into JSON schema, and back.

Usage

Global (CLI)

npm install -g ramldt2jsonschema

This will install two command-line tools:

• dt2js: RAML data type <> JSON schema
• js2dt: JSON schema <> RAML data type

dt2js

dt2js <ramlFile> <ramlTypeName>

Options

• <ramlFile> Path to a file containing at least one RAML data type (e.g. path/to/api.raml)
• <ramlTypeName> RAML type name to convert to JSON schema

js2dt

js2dt <jsonFile> <ramlTypeName>

Options

• <jsonFile> Path to a JSON schema file (e.g. path/to/schema.json)
• <ramlTypeName> RAML type name to give to the exported RAML data type

Locally (JavaScript)

npm install ramldt2jsonschema --save

dt2js

var raml2json = require('ramldt2jsonschema')
var join = require('path').join
var fs = require('fs')

var filePath = join(__dirname, 'api.raml')
var ramlData = fs.readFileSync(filePath).toString()

raml2json.dt2js(ramlData, 'Cat', function (err, schema) {
  if (err) {
    console.log(err)
    return
  }
  console.log(JSON.stringify(schema, null, 2))
})

js2dt

var raml2json = require('ramldt2jsonschema')
var join = require('path').join
var fs = require('fs')

var filePath = join(__dirname, 'schema.json')
var jsonData = fs.readFileSync(filePath).toString()

raml2json.js2dt(jsonData, 'Person', function (err, raml) {
  if (err) {
    console.log(err)
    return
  }
  console.log('#%RAML 1.0 Library\n')
  console.log(raml)
})

Limitations

• in js2dt,

  • the following JSON schema properties are not supported and as a result, will not be converted:
    • format, title, not
    • number and integer's exclusiveMaximum and exclusiveMinimum
    • object's patternProperties and dependencies
    • array's additionalItems
  • the JSON schema oneOf property is processed the same way as the JSON schema anyOf property, it is converted to the RAML union type
  • the JSON schema type: 'string' with media and binaryEncoding: 'binary' is converted to the RAML file type
  • the JSON schema type: string with a pattern that matches exactly one of the RAML date types will be converted in the matching RAML date type
  • the JSON schema media property with anyOf, elements of which have the property mediaType will be converted to fileTypes in RAML

• in dt2js,

  • the following RAML properties are not supported/converted:
    • pattern properties, annotations
    • displayName
