I'd like to give this a go..... :)

@emma-r-slight thank you, please make it dynamic and any meta data you want to add to course model or user model please let me know, I'll assign you

Do you have any preference for a template(view) engine? express-handlebars, pug, dots.....? What information do you want to be listed from the course routes? Do you want just a list with name and tags, do you want to include an external link to the course?

I was thinking about ejs but never used it, also I was planning to learn React
As a first step we can show their names and tags maybe we can edit the model too to add photos or another metadata
What do you think?

Ok, I have used express handlebars before, which is quite a good stepping stone to react. It separates parts of the page into components similar to React.

For the courses I was looking at the Udemy page, it looks like there's an image( at this point I don't think it needs to be saved in the db, just use a random image from unsplash.com), Title, name of creater and then topic(tags).

Do you have a problem if I add some tests using Jest?

Do you have a problem if I add some tests using Jest?

No, I know jest and was planning to have tests but i don't know how until now and will we apply unit or integration testing, what do you think ?

At this point unit testing, I haven't used Nosql databases before (only SQL Databases) so wanted to write tests for the 'courses' db and api route.
This is a great article about testing 'login' if you were interested. It shows how to setup a Mongodb.config file for testing
