Rust’s module system and the terminologies are unique to other programming languages. Understanding Rust’s module system takes a lot of reading and sometimes we are in a hurry to use the features right away. In this post, I will give you real-world examples of Rust’s module system. However, I still recommend reading the official Rust book whenever you are free.

Theory

Understanding Rust’s module system requires the knowledge of crate, modules and path.

I have been using React for the last 3 years. And every time I need to create a front-end project with React, I would open a terminal, run the create-react-app command and it would magically create a whole react project. I have also used vite to create react projects but never understood how these tools create and configure a react app.

Today I will try to understand how all of these tool chain that creates a react project scaffolding with ready to go configuration. And possibly create a react project from scratch too.
