Safely extract deeply nested properties – because safety is number one priority
npm install diggsA lightweight utility to safely dig into nested properties – because safety is number one priority.
To install diggs:
```
npm install --save diggs
That's it!
?diggs allows you to access deeply nested properties without having to worry about undefined properties, null, or TypeErrors.
`javascript`
// Uncaught TypeError: Cannot read property 'foo' of null
// Uncaught TypeError: Cannot read property 'foo' of undefined
`javascript
import { get } from 'diggs';
let data = {
a: {
b: {
c: ['foo', { d: 'bar' }],
}
},
z: null,
}
// retrieve deeply nested properties
get(data, 'a.b.c') // => ['foo', { d: 'bar' }]
// even array items
get(data, 'a.b.c[1].d') // => 'bar'
// returns undefined instead of throwing TypeErrors
get(data, 'z.a') // => undefined
// returns a default value
get(data, 'z.a', false) // => false
`
