Use powerful dot notation (dot path + wildcard) to access properties of JSON.
If you need to do set or delete, use dot-wild which has all functions.
$ npm install dot-wild-tiny --save # or $ yarn add dot-wild-tinyimport * as dot from 'dot-wild-tiny'; /** * Getter */ dot.get({ foo: { bar: 'baz' } }, 'foo.bar'); // => 'baz' dot.get({ 'foo.bar': 'baz' }, 'foo\\.bar'); // => 'baz' dot.get({ 'foo.bar': 'baz' }, 'notfound', 'default'); // => 'default' const authorData = { authors: [ { username: 'tsuyoshiwada', profile: { age: 24 } }, { username: 'sampleuser', profile: { age: 30 } }, { username: 'foobarbaz', profile: { age: 33 } } ] }; dot.get(authorData, 'authors.*.username'); // => ['tsuyoshiwada', 'sampleuser', 'foobarbaz'] dot.get(authorData, 'authors.*.profile.age'); // => [24, 30, 33] /** * Collection helpers (forEach, map) */ dot.forEach(postData, 'data.posts.*.id', (value, key, context, path, data) => { // value => 1, 2 // key => 'id', 'id' // context => { id: 1, title: 'post 1' }, { id: 2, title: 'post 2' } // path => 'data.posts.0.id', 'data.posts.1.id' // data => postData... }); dot.map(postData, 'data.tags.*.name', (value, key, context, path, data) => { return `${dot.get(data, path)} === ${value} (${key})`; }); // => ['tag 1 === tag 1 (name)', 'tag 2 === tag 2 (name)']- Fork it!
