A module that merges the passed in objects recursively while concatenating internal arrays. The procedure is completely functional, so it does not mutate any argument.
-
Run
npm install --save https://github.com/techiedod/merge-concat, oryarn add https://github.com/techiedod/merge-concat
-
// ES6 import mergeConcat from 'merge-concat' // It can take any number of arguments // with the latter taking precedence. mergeConcat( { a: { b: 0 }, d: [ 'z' ] }, { a: { b: 1, c: 2, e: [ 'x', 'y' ] } }, { a: { c: 3, e: [ 'u' ] }, d: [ 'v' ] } ) //=> { a: { b: 1, c: 3, e: [ 'x', 'y', 'u' ] }, d: [ 'z', 'v' ] } // Any non-object arguments will be converted // to empty objects. In other words, it's // simply ignored. mergeConcat( { a: 2, b: { c: 4 } }, null, { b: { c: 6 } }, undefined, { a: 8 }, 'String', ['array'] ) //=> { a: 8, b: { c: 6 } } // ES5 var mergeConcat = require('merge-concat') mergeConcat({ /*...*/ }, { /*...*/ }, /*...*/)

Just include
./dist/merge-concat.jsbefore the closing<body>tag and then simply callmergeConcatorwindow.mergeConcatwith the objects you want to deep merge.
