Whether you should learn Express.js before Nest.js depends on your existing knowledge and goals. Here's some information to help you decide:
Understanding Express.js:
Express.js is a minimal and flexible Node.js web application framework that provides a robust set of features to develop web and mobile applications. It's widely used and considered a fundamental framework for building server-side applications in JavaScript.
Learning Express.js will give you a solid foundation in handling HTTP requests, routing, middleware usage, and building APIs in a Node.js environment.
Nest.js and Its Relationship to Express.js:
Nest.js is a progressive Node.js framework for building efficient, reliable, and scalable server-side applications. It is built on top of Express.js, leveraging its features and adding a layer of abstraction to enhance code organization and modularity.
Nest.js uses similar concepts to Express.js but introduces a more structured approach through decorators, modules, and dependency injection.
Choosing the Learning Path:
If you are new to backend development or have limited experience with Node.js, starting with Express.js can be beneficial. It will help you grasp the basics of routing, middleware, and handling requests in a Node.js environment.
If you already have a good understanding of Node.js and want to adopt a more structured and organized approach to building applications, you can start directly with Nest.js. You'll learn how to leverage the capabilities of Express.js within the Nest.js framework.
Learning Curve and Personal Preference:
Express.js has a simpler and more straightforward learning curve, making it a good choice for beginners or those who want to quickly start building APIs with Node.js.
Nest.js, on the other hand, has a learning curve associated with understanding its structure, modules, and dependency injection. However, many developers appreciate its organization and maintainability.
