Package Exports

jsonapi-query-parser

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (jsonapi-query-parser) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

node-jsonapi-query-parser

JsonApiQueryParser class to parse endpoint and its query string parameters to a usable request object.

To be used for ES6 node projects that make use of JSON API

Installation

Install using npm install jsonapi-query-parser

Usage

Require the module 'JsonApiQueryParser' into your application and use the 'parseRequest' function to convert the request.url to an easy usable requestData object.

let JsonApiQueryParser = require('JsonApiQueryParser');

http.createServer(function (request, response) {
  let requestData = JsonApiQueryParser.parseRequest(request.url);
}).listen(1337, '127.0.0.1');

Return data information (requestData)

The object returned by the JsonApiQueryParser.parseRequest will always be the same structure. Below you can see 2 parsed examples:

//EXAMPLE 1
let url = '/article/5/relationships/comment'
let requestData = {
  resourceType: 'article',
  identifier: '5',
  relationships: true,
  relationshipType: 'comment',
  queryData: {
    include: [],
    fields: {},
    sort: [],
    page: {},
    filter: []
  }
};

//EXAMPLE 2
let url = '/article/5/?include=user,comment.user&fields[article]=title,body&page[limit]=20&sort=-createdon'
let requestData = {
  resourceType: 'article',
  identifier: '5',
  relationships: false,
  relationshipType: null,
  queryData: {
    include: ['user', 'comment.user'],
    fields: {
      article: ['title', 'body']
    },
    sort: ['-createdon'],
    page: {
      limit: 20
    },
    filter: []
  }
};

Important

If your endpoints contain versioning or other application specific pointers please remove them before parsing! Here are some examples of a request url:

  let CORRECT1 = '/article/'
  let CORRECT2 = '/article/5?include=comments'
  let CORRECT3 = '/article/5/relationships/comments'
  let CORRECT4 = '/article/?include=user,comment.rating&fields[article]=title,body&fields[user]=name'
  let WRONG = '/v1/api/article?include=user

Missing implementation

Filters are not properly parsed since there are no proper specifications on this part yet! I hope to update this package as soon as filtering specs are set.
