ES6 将两个变量组合成一个现有的 javaScript 对象

Question

I'm currently returning createdAt and updatedAt outside of the data object, I want to add them to the data object so I can return a single object.

I've also noticed I'm getting $init: true from somewhere, how to get rid of this?

  static profile = async (req: Request, res: Response) => {
    try {
      const { username } = req.params;
      const account = await userModel
        .findOne({ 'shared.username': username })
        .exec();
      if (account) {
        const {email, loggedIn, location, warningMessage, ...data} = account.shared;
        const { updatedAt, createdAt } = account;
        res
          .status(200)
          .send({ data, updatedAt, createdAt }); // <=== How to combine updatedAt & createdAt into data?
      } else res.status(400).send({ message: 'Server Error' });
    } catch (error) {
      res.status(400).send({ message: 'Server Error', error });
    }
  };

The current result is

createdAt: "2019-12-13T12:15:05.031Z"
data: {
 $init: true // <=== why is this here, where did it come from?
 avatarId: "338fcdd84627317fa66aa6738346232781fd3c4b.jpg"
 country: "AS"
 fullName: "Bill"
 gender: "male"
 language: "en"
 username: "bill"
}
updatedAt: "2019-12-14T16:07:34.923Z"

Answer 1

Use spread operator:

{ ...data, updatedAt, createdAt }

Be warning, your variable name gonna be your index

Answer 2

To remove $init but nothing else.

const {$init, ...cleanData} = data;

To create a data object with createdAt and updatedAt

const finalData = {...cleanData, createdAt, updatedAt}

Happy coding!

Answer 3

Just use .toObject() like so:

static profile = async (req: Request, res: Response) => {
try {
  const { username } = req.params;
  const _account = await userModel
    .findOne({ 'shared.username': username })
    .exec();
  const account = _account.toObject()
  if (account) {
    const {email, loggedIn, location, warningMessage, ...data} = account.shared;
    const { updatedAt, createdAt } = account;
    res
      .status(200)
      .send({ data: { ...data, ...{ updatedAt, createdAt }} });
  } else res.status(400).send({ message: 'Server Error' });
} catch (error) {
  res.status(400).send({ message: 'Server Error', error });
}

};
