QUESTION
I know this has been asked a lot but I can't seem to use the existing answers to get my code to work. I am trying to use mongojs to make a single query, then put the results in a global (relative to the scope) variable to avoid nesting multiple callbacks. However, I can't seem to get the code to wait for the query to end before continuing.
...ANSWER
Answered 2021-Apr-05 at 18:04Inside your async function, you use findOne method() in callback style, so it's totally normal that console.log(currentDoc) shows undefined, because it executes before
currentDoc = doc;
You can promisify the findOne method, to use it with async/await keyword.
I found a tutorial to promisfy a callback style function here, hope it help : https://flaviocopes.com/node-promisify/
--- EDIT ---
I rewrite your code when promising the findOne method, as suggested by O.Jones
QUESTION
I am learning to implement API using Node.js, Express and MongoDB. I am on early learning phase. I have added cors package using npm i cors to the project. And I am using cors as middleware in my project as follows.
ANSWER
Answered 2020-Dec-10 at 06:10Based on your question and your subsequent comment, it sounds like there a couple things going on here:
CORS protections are only enforced by an actual browser engine. If you're making the requests from a non-browser client, then there are no CORS limitations.
To trigger a CORs protection from a browser, you have to be making an actual cross origin call. If everything is on
localhost, then that won't be cross origin.

I am at the early stages of a simple tasks manager that I want to build with the MEAN Stack. I can figure/resolve a simple routing issue. I don't see any error message in the terminal or console except for the 404 client error.
the root path is ok. I get a response back I use html docs to render the ui for both.
this is how I have set up my server.js
ANSWER
Answered 2017-Sep-22 at 05:18This error occurs because there's no route that handles the endpoint /api. What you can do here is create a middleware that will handle the /api. You can do it in your tasks.js like this:
tasks.js
QUESTION
This is the code I used as I've been learning fullstack online as this is the code they used, but I keep getting the error message that req.checkBody is not a function. I've tried reverting back to an earlier version of express-validator but can't seem to do that either. Apparently express-validator was updated which is why req.checkBody is no longer a function but I can't seem to fix my code.

And then you can try running this

I'm stuck. I keep getting the same cb is not a function error. Here's my error:
TypeError: cb is not a function
I just started learning javascript a few days ago, so I'm very new. I'm simply watching youtube videos that do what I need done for my application and I write what they write. So far it's been going well, had a few problems that I managed to fix on my own. But this one I can't figure out. So a little help would be very much appreciated.
...ANSWER
Answered 2019-Jul-08 at 01:26Welcome to Stackoverflow, the cb is usually referred as callback function to pass to another function, I think in your code you don't need this. Probably you referenced the code from the documentation of Socket.io or MongoDB where they often use to pass a callback function as result.
I see from your code that you just need to pass true/false as result of db operation, so just remove the cb parameter from your functions and return just true/false:
