I’m a big believer that database systems share similar core fundamentals at their storage layer and understanding them allows one to compare different DBMS objectively. For example, How documents are stored in MongoDB is no different from how MySQL or PostgreSQL store rows.
Everything goes to disk, the trick is to fetch what you need from disk efficiently with as fewer I/Os as possible, the rest is API.

In this video I discuss the evolution of MongoDB internal architecture on how documents are stored and retrieved focusing on the index storage representation. I assume the reader is well versed with fundamentals of database engineering such as indexes, B+Trees, data files, WAL etc, you may pick up my database course to learn the skills.
Let us get started.

We are going to cover how to create a restful api using node.js express and mongodb together with mongoose.

Rest apis help us decouple our backend code from our front end so we can use it across multiple application (mobile apps, web apps, etc).
We are going to learn how to build a simple blog post type api with all the useful methods(GET,POST,DELETE,PATCH).

We use Node.js as our backend language, express.js is going to help us create routes easier and middlewares and we use mongodb together with mongoose to create schemas and models that define how our data looks.

If you are a beginner with nodejs, express or mongodb I hope that this tutorial will give you a good idea of how these technologies work well together.
