transform-object-dot-notation

Transform object string dot notation into object reference

Example

Accessing deeply nested properties

const obj = {
  foo: {
    bar: {
      baz: {
        val: 'hello world',
      },
    },
  },
};

const val = obj['foo.bar.baz.val']  // hello world

Calling deeply nested functions

const obj = {
  foo: {
    bar: {
      baz: class {
      },
    },
  },
};

const baz = new obj['foo.bar.baz'] // baz instance

Constructing deeply nested classes

const obj = {
  foo: {
    bar: {
      baz: function() {
        return 'hello world'
      },
    },
  },
};

const baz = obj['foo.bar.baz']() // hello world

With Optional Chaining Proposal

const obj = {
  foo: {
    bar: {
      baz: 30,
    },
  },
};

const safe = obj['foo?.quiz?.baz'] // undefined

In this case, transform-object-dot-notation should be placed before @babel/plugin-proposal-optional-chaining
