Access nested object properties via strings, with existential operator (?) support.
var deep = require('deep-access');
var obj = {
foo: 'bar',
bar: {
baz: {
beep: 'boop'
}
}
};
console.log(deep(obj, 'foo'));
// => "bar"
console.log(deep(obj, 'bar.baz.beep'));
// => "boop"
console.log(deep(obj, 'foo.beep.boop'));
// throws
console.log(deep(obj, 'foo.beep?.boop'));
// => undefinedAccess obj's property prop. The property string may contain key names, dots
and question marks. If a key ends with an question mark but doesn't
exist, the algorithm aborts and returns what it last got.
With npm do:
npm install deep-access(MIT)
