only one object being set to app.set() Expressjs

Asked 2021-Jun-11 at 19:25

Good Afternoon, I am using the MERN stack to making a simple invoice application. I have a function that runs 2 forEach() that goes through the invoices in the DB and the Users. if the emails match then it gives the invoices for that user. When I log DBElement to the console it works, it has the proper data, but when I log test1 to the console (app.get()) it only has one object not both.

...

ANSWER

Answered 2021-Jun-11 at 18:59

app.set('test', DBElement); overrides the existing DBElement, so only the last matching DBElement is shown in test1.

If you want to have test correspond to all matching DBElement, you should set it to an array, and then append a new DBElement to the array each time it matches inside the for-loop:

Good Evening, I am using the MERN stack to create an application. I am using the Stripe API to gather invoices and save some information about the invoice in MongoDB. Right now I have a function that updates my DB with any object that does not exist and I have a delete function that deletes any documents in my DB that have the paid: true. when an invoice is paid Stripe marks it paid, when its paid I want to delete it from my DB. What happens now is that I delete it and then update function runs and just puts it right back.

The data in my DB and from stripe are an array of objects:

The save function takes in the data gathered from the findCommonId() function and if the id doesn't exist it adds the stripe object to the DB.

You should check your Node version on the server. Most probably it's older and you're using ES6 exports.

If you got the right version that supports ES6, then you should make sure you've enabled that (as CommonJS is the default option). From the docs:

Files ending in .mjs.
Files ending in .js when the nearest parent package.json file contains a top-level "type" field with a value of "module".
Strings passed in as an argument to --eval, or piped to node via STDIN, with the flag --input-type=module.

QUESTION

Do creating a React app enables ES Modules?

Asked 2021-Jun-10 at 12:10

I am learning MERN and starting of the backend section I learned that we have to enable ESM in package.JSON to use import and export but in building frontend with react nothing has to be done

...

ANSWER

Answered 2021-Jun-10 at 12:10

React itself doesn't care.

Whether you do or don't need to configure anything depends on the tools you use for your frontend development.

Eg. create-react-app and Vite configure the bundlers they use to work with ESM, but if you start from scratch, with e.g. your own Webpack configuration, you'll need to figure out the configuration yourself.

QUESTION

How could I filter product by price in react?

Asked 2021-Jun-09 at 14:54

I'm working on a MERN stack project where users can filter products by price. Products are coming from a database and each has a price. How could I do this with react? I've no idea about how to get started working on this feature, so no code snipper is attached.

...

ANSWER

Answered 2021-Jun-09 at 14:54

I recommend you to filter this in the backend because this could be expensive in terms of computing resources and time (they could be thousands of product records).

So, when the user fires an event to filter by price, then a API request should be sent to your backend to filter the products in the the MongoDB collection and returns only the products the client needs.

How to format a mysql duplicate entry error?

Asked 2021-Jun-06 at 13:53

I'm using express.js with mysql2.

When a duplicate entry error happens on insertion I get the error in the global error handler and that works as expected.

When I log it to the console, the error looks like this:

ANSWER

Answered 2021-Jun-06 at 13:53

I actually came up with a decent solution.

Because the sqlMessage will always be in the same format, I first split the sqlMessage into an array, and then extracted the value entered, and then I also extracted the field, but since the field is in a format "database.field_UNIQUE", I had to extract the field that is in between the "." and "_" characters.

The code looks like this:
