Nested Groupby

Nested Groupby is a node module to group objects in an array similar to Lodash's groupBy method, but to group the objects by more than one key.

Examples

See this Codepen for demo.

        import nestedGroupby from 'nested-groupby';
        // For commonjs
        // const nestedGroupby = require('nested-groupby');

        const data = [
          { type: 'apple', color: 'green', quantity: 1000 },
          { type: 'apple', color: 'red', quantity: 2000 },
          { type: 'grape', color: 'green', quantity: 1000 },
          { type: 'grape', color: 'red', quantity: 4000 },
        ];

        nestedGroupby(data, ['type', 'color']);

        // output will be the following
        // {
        //   apple: {
        //     green: [ { type: 'apple', color: 'green', quantity: 1000 } ],
        //     red: [ { type: 'apple', color: 'red', quantity: 2000 } ]
        //   },
        //   grape: {
        //     green: [ { type: 'grape', color: 'green', quantity: 1000 } ],
        //     red: [ { type: 'grape', color: 'red', quantity: 4000 } ]
        //   }
        // }
