Acerca de este curso

  • Introduction to Node.js and Express
    • This module will introduce you to Node.js and Express, two fundamental technologies for building modern web applications. You will learn how to set up your development environment, install Node.js and NPM, and create your first Node.js application.

      You will start by exploring the features of Node.js and its unique architecture, including the event loop and non-blocking I/O model. You will also learn how to use the built-in modules and NPM to install and manage dependencies.

      Next, you will dive into Express, a popular web framework built on top of Node.js. You will learn how to install and configure Express, create a simple web server, and handle HTTP requests and responses.

      In this module, you will also learn how to use middleware to add functionality to your Express application, including logging, error handling, and parsing request bodies. You will also learn how to use template engines to render dynamic views and serve static files.

      By the end of this module, you will have a solid understanding of the basics of Node.js and Express, and be ready to dive deeper into building RESTful APIs in the following modules.
  • Working with Databases and MongoDB
    • This module will teach you how to work with databases in Node.js using MongoDB, a popular NoSQL database. You will learn how to connect to a MongoDB database, create collections and documents, and perform CRUD operations using the MongoDB driver.

      You will start by understanding the basics of NoSQL databases and their advantages over traditional relational databases. You will learn how to set up and configure MongoDB, and how to interact with it using the command line and the MongoDB Compass GUI.

      Next, you will learn how to use the MongoDB driver in Node.js to perform CRUD operations on the database, including inserting, updating, and deleting documents. You will also learn how to query the database using the MongoDB query language and perform aggregation operations.

      By the end of this module, you will have the skills and knowledge to work with databases in Node.js using MongoDB. You will be able to create and interact with databases and perform CRUD operations using the MongoDB driver.
  • Advanced Topics in Node.js and Express
    • This module will cover advanced topics in Node.js and Express, including asynchronous programming, error handling, security, and testing. You will learn how to write scalable and maintainable code, handle errors and exceptions, and implement security measures to protect your application.

      You will start by understanding the importance of asynchronous programming in Node.js, and how to use callbacks, promises, and async/await to handle asynchronous operations. You will also learn how to use the async module to manage asynchronous control flow and avoid callback hell.

      Next, you will learn how to handle errors and exceptions in your Node.js and Express applications, including using try/catch blocks, error middleware, and global error handling. You will also learn how to use logging frameworks to log errors and monitor your application.

      By the end of this module, you will have the skills and knowledge to write scalable, maintainable, and secure Node.js and Express applications, and be able to write automated tests to ensure the quality of your code.
