JSON API Query Param Parser

Provides a function to parse the include JSON API query parameter into an object.

Installation

$ npm i json-api-query-parser

Description

The JSON API specification provides ways to request a resources relations (include) via query parameters. These relations are provided as a comma separated string, which this module transforms into an object.

Usage

const { includeParser } = require('json-api-query-param-parser');

console.dir(includeParser('author'), { depth: null });
// { author: [] }

console.dir(includeParser('author.comments'), { depth: null });
// { author: ['comments'] }

console.dir(includeParser('author.comments.author'), { depth: null });
// { author: [ { comments: ['author'] } ] }

console.dir(includeParser('author.comments,author.books'), { depth: null });
// { author: ['comments', 'books'] }

console.dir(includeParser('author.comment-logs,author.books', { convertCase: 'camelCase' }), { depth: null });
// { author: ['commentLogs', 'books'] }

You can also provide an object with the following options:
