A parser for swagger object properties ,mock data returned by chancejs


version 1.2.0

break change: object parser use JSON.stringfy to break circular references in schema

version 1.1.14

add useObjectKey option,set this true ,String parser will return the key name;

version 1.1.13

add fixedArray option,set this true ,array parser will return only one child array

version 1.1.12

detect and fix circular references in schema and return null object

version 1.1.8 ~ 1.1.11

add useExample option,set this true parser will return defined example first

version 1.1.7

break change: return string instead of throw error,objectParser canParse add "node.type == object" judge condition


An example for mocking swagger definition schema

// basic usage
var Parser = require('swagger-mock-parser')
var parser = new Parser();
var schema = definition.schema;
return parser.parse(schema);
// useExample option
var Parser = require('swagger-mock-parser')
// set useExample true will return every property's example which has already defined
var parser = new Parser({useExample: true});
var schema = {type: 'string', example: 'will return example first'}
return parser.parse(schema);
// useObjectKey option
var Parser = require('swagger-mock-parser')
// set useObjectKey true will return every Object property's name as the string value,but useExample is prior
var parser = new Parser({useExample: true, useObjectKey: true});
var hasExampleSchema ={
    type: 'object',
    properties: {
        objectKeyName: {type: 'string', example: 'useExample prior'}
var noExampleSchema ={
    type: 'object',
    properties: {
        objectKeyName: {type: 'string', example: ''}
// this will return { objectKeyName: 'useExample prior' }
return parser.parse(hasExampleSchema);
// this will return { objectKeyName: 'objectKeyName' }
return parser.parse(noExampleSchema);

Specifying custom Chance options

Swagger specifies only a few primitive types; for scenarios where specific chance methods are needed, use the x-chance-type field.

        type: string
        x-chance-type: name
        type: string
        x-chance-type: guid

Most of the chance methods allow some fine-tuning of the returned data. For example, the integer method allows specification of minimum and maximum output values. These options can be configured in the Swagger YAML file with the x-chance-options block:

      $ref: '#/definitions/NewPet'
        - id
            type: integer
            format: int64
              min: 1
              max: 1000

A note on types:

All of the primitive types defined in the Swagger specification are supported except for file and password. Currently, the format property is ignored; use x-chance-type instead. The server will error on any request with a type other than one of the primitive types if there is no valid x-chance-type also defined.

Returning Fixed Values

Although not a chance method, support has been added for returning fixed values using x-chance-type: fixed. Any value given for the custom tag x-type-value will be returned; below is an example where an object is returned:

      type: object
      x-chance-type: fixed
        type: 'adopted'
