CLI & Library to convert a RAML 1.0 DataType to a JSON Schema Draft 4, and back. Uses webapi-parser under the hood.
```
npm install -g ramldt2jsonschema
This will install two command-line tools:
- dt2js: RAML data type <> JSON schemajs2dt
- : JSON schema <> RAML data type
#### dt2js
``
dt2js
Options
* Path to a file containing at least one RAML data type (e.g. path/to/api.raml)
* RAML type name to convert to JSON schema--draft
* Optional JSON Shema draft version to convert to. Supported values are: 04, 06 and 07 (default)--validate
* Validate output JSON Schema with Ajv. Throws an error if schema is invalid. Requires "ajv" to be installed. (default: false)
#### js2dt
``
js2dt
Options
* Path to a JSON schema file (e.g. path/to/schema.json)
* RAML type name to give to the exported RAML data type--validate
* Validate output RAML with webapi-parser. Throws an error if it is invalid. (default: false)
``
npm install ramldt2jsonschema --save
#### dt2js
`js
const r2j = require('ramldt2jsonschema')
const join = require('path').join
const fs = require('fs')
const filePath = join(__dirname, 'complex_cat.raml')
const ramlData = fs.readFileSync(filePath).toString()
async function main () {
let schema
try {
schema = await r2j.dt2js(ramlData, 'Cat')
} catch (err) {
console.log(err)
return
}
console.log(JSON.stringify(schema, null, 2))
}
main()
`
#### js2dt
`js
const r2j = require('ramldt2jsonschema')
const join = require('path').join
const fs = require('fs')
const yaml = require('js-yaml')
const filePath = join(__dirname, 'complex_cat.json')
const jsonData = fs.readFileSync(filePath).toString()
async function main () {
let raml
try {
raml = await r2j.js2dt(jsonData, 'Cat')
} catch (err) {
console.log(err)
return
}
console.log('#%RAML 1.0 Library\n')
console.log(yaml.safeDump(raml, { 'noRefs': true }))
}
main()
`
#### Resolving references
When the input contains external references (!include, uses:, $ref, etc.) and the referred files are not in the same directory as the script it is being ran from, you may provide a third argument to both dt2js and js2dt. The argument must be an object with a basePath key. All references will then be resolved relative to that base path.
Example of using basePath argument in dt2js:`js
// Script below ran from /home/john/where/ever/
// Reference is located at /home/john/schemas/simple_person.json
const raml2json = require('ramldt2jsonschema')
const ramlStr =
#%RAML 1.0 Library
types:
Person: !include simple_person.json`
const basePath = '/home/john/schemas/' // or '../../schemas/'
const schema = raml2json.dt2js(ramlStr, 'Person', { basePath: basePath })
console.log(JSON.stringify(schema, null, 2))
- in js2dt
- the following JSON Schema properties are not supported and as a result, may not be converted as expected:
> dependencies, exclusiveMaximum, exclusiveMinimum, items (array value), allOf, oneOf, not, format (email, hostname, ipv4, ipv6, uri), readOnly
- the following JSON Schema properties won't be converted at all:
> $schema, additionalItems, contains, id, $id, propertyNames, definitions, links, fragmentResolution, media, pathStart, targetSchema
- array items` property is not properly converted to RAML when it's value is an array of schemas (see #111)
