Mongodb – How can I get the total count of records in mongo db database using Express.js

Here is my Controller

    const getCountofCenters = async (req, res) => {
        
        const result =  Center.countDocuments();
            
        await result.then(() => res.status(200).send(result))
            .catch((err) => {
                res.status(200).send(err)
            });   
    }

This is the Api call

    router.get("/count", CenterController.getCountofCenters);

This is the output which I get from the Postman test, empty array

    {}

    Try this:

    const getCountofCenters = async (req, res) => {
  try {
    const result = await Center.countDocuments();
    return res.status(200).json(result);
  } catch {
    return res.status(400).json({ success: false });
  }
}

    model.countDocuments returns a promise that you need to resolve so you can get the value of count
    so the correct implementation on this within an async function is

    await Center.countDocuments()

    then sequentially you can return the response
