ramldt2jsonschema

CLI & Library to convert a RAML 1.0 DataType to a JSON Schema Draft 6, and back. (dt2js can still be used to produce draft04 documents if used programatically)

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

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

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

const schema = raml2json.dt2js(ramlData, 'Cat')
console.log(JSON.stringify(schema, null, 2))

NOTE: when the inputed RAML contains !includes and those includes are not in the same directory as the script it is being ran from, you can use dt2js.setBasePath() to specify a different base path.

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

const filePath = join(__dirname, 'api.raml')
const includesPath = '/different/path/to/includes/'
const ramlData = fs.readFileSync(filePath).toString()

raml2json.dt2js.setBasePath(includesPath)
const schema = raml2json.dt2js(ramlData, 'Cat')
console.log(JSON.stringify(schema, null, 2))

js2dt

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

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

const raml = raml2json.js2dt(jsonData, 'Person')

console.log(`#%RAML 1.0 Library\n${yaml.safeDump({ types: raml }, {'noRefs': true})}`)

Limitations

• in js2dt,

  • the following JSON schema properties are not supported and as a result, will not be converted:
    • not (or false when used as a schema boolean)
    • object's dependencies
    • array's additionalItems
    • the propertyNames keyword
    • the contains keyword
  • JSON schema number and integer's exclusiveMaximum and exclusiveMinimum properties are converted to raml 'maximum' and 'minimum'
  • 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:
    • annotations
