Get inserted document directly in RethinkDB

Question

I have been starting with RethinkDB. I have gone through the documentation. I have a simple use case of returning the inserted document when a POST call is made. This is something I have done so far.

router.post('/user', jsonParser, async (req: Request, res: Response) => {
  const connection = await conn;

  const { name, email, employeeId } = req.body;
  // Email is primary key
  consumerTable.insert({
    name,
    email,
    employeeId,
  }).run(connection, (err: any, result: any) => {
    if (err) {
      throw err;
    } else {
      consumerTable.get(email).run(connection, (innerErr: any, userResult: any) => {
        if(innerErr) {
          throw innerErr;
        } else {
          res.send({
            data: {
              ...userResult
            },
            responseCode: 200,
          });
        }
      });
    }
  });
});

Is there any way to get the inserted object in the insert result itself. I read a lot of documentation, but didn't find anything useful.

Any help would be great. Cheers!

You may use the returnChanges option of the insert command as specified in the documentation. It should look like this:

consumerTable.insert({
    name,
    email,
    employeeId,
}, { returnChanges: true }).run(connection, async (err: any, cursor: any) => {
    const data = await cursor.toArray();
    // .error should be undefined, unless... an error happened!
    // not sure about the format though, console.log data to check it really is an array
    res.send({ data: data[0].new_val, error: data[0].error });
});
