Retrieve and display all records from a MongoDB collection using a function, then showcase them using express

Is there a way to retrieve and display all documents from MongoDB by creating a function that establishes a connection to the client and retrieves values? I attempted to use the toArray method, but unfortunately, the ID does not show up in the response when I test it on Postman.

database.js

exports.getFromDb = (uri) => {
 MongoClient.connect(uri, (err, db) => {
    if (err) throw err;
    var dbo = db.db("ToDoList");
     var documents = dbo.collection("ToDo").find({});})}

index.js

app.get("/", (req, res) => {
    return res.json(getFromDb(uri))
});
 

Answer №1

Patience is key when retrieving data from the database.

Here's an example:

app.get("/data", async (request, response) => {
    try {
        const information = await fetchDataFromDatabase(url);
        return response.status(200).json(information);
    } catch (error) {
        ...
    }
});
