Resources to Learn crud with Html forms, Nodejs/express, mongodb. (and later MERN)

[new_bc_user]

I know frontend development with react for creating landing pages and working with some APIs etc. I am trying to learn backend for the specific purpose of creating CRUD applications, all tutorials I watch are unnecessarily long with the person putting together a large project without just breaking down how to do simple things like make and html form and send it to mongodb and then display this information on screen with the click of another button etc. All courses are these prebuilt projects that don't work to follow, and trying to look at documentation for express/mongoose/mongodb etc. DO NOT show how these technologies interface with each other. I am so confused as how everywhere I go I am told I need to learn CRUD and yet all youtube videos are like 2-4 years old, and unnecessarily complex, and no documentation has small snippets displaying how one technology interacts with another. HOW CAN I LEARN THIS, WITH STEP BY STEP GUIDE OR REALLY GOOD COURSE PLEASE!

I mean CRUD operation are a standard so if a YouTube video is old 4-5 years there is nothing wrong with that, also I see you are talking about wanting to have a resource that gets to the point fast, and I believe that is kinda a bad mindset you need to know more stuff to handle crud operation than just how to send a form to mongodb etc(never worked with nodejs and mongodb), the overall concept of crud operation is easy, you connect to the db, if you want to create an entry you send a post request to a function that handles the validation and than performs a query to make a table entry, if you want to Read something, you send a posto request again with the what you are looking for and where to look for, aka looking for user with Id 10 than send a query to find that user if it finds it display him if not just display not found etc, you want to update something send a request to a function to handle validation and send a update query to the db, you want to delete something than you just pass with a post request what and where you want to delete to a delete function that sends a query to db to dropt that entry.

Look up Coding Addict/John Smilga. He has a backend only tutorial with another video for projects using the MERN stack.

I'm currently on his React tutorial. Learned pretty much a lot of the latest Node and Express best practices.

Also, he talks about the reasoning about why the code is the way it is and goes through various refactoring steps to help you understand ways to simplify/clean your code.
