Swagger-parameters NPM

swagger-parameters

Validate and parse request data using swagger parameters arrays

swagger-parameters turns your Swagger/OpenAPI parameters into a full JSON schema that can be used to parse and validate HTTP request data. The library is fully server-agnostic. You're responsible for converting your request paths and queries into key-value data. swagger-parameters will perform validation and type coercion and return a copy of your parsed data (if valid).

Install

$ npm install --save swagger-parameters

Usage

var Parser = require('swagger-parameters')
// var Schema = require('swagger-parameters/schema')

// /users/{id}/orders?page={page}
var parse = Parser([
  {
    name: 'id',
    in: 'path',
    type: 'integer',
    required: true
  },
  {
    name: 'page',
    in: 'query',
    default: 1,
    type: 'integer'
  },
  {
    name: 'token',
    in: 'header',
    required: true
  }
])

parse({
  path: {id: '1'},
  query: {page: '5'},
  headers: {token: 't'}
}, function (err, data) {
  if (err) throw err
  console.log(data)
  //=> {path: {id: 1}, query: {page: 5}, headers: {token: 't'}}
})
