Creating an Express Server and Understanding Routes
Description:
In this hands-on session, you will delve into the world of Express, a popular and powerful Node.js framework. You will learn how to set up a basic server using Express and define a custom route "/api/main" that will provide a comprehensive understanding of what Express is and its role in web development.
Requirements:
- Basic knowledge of JavaScript and Node.js
- Node.js and npm (Node Package Manager) installed on your machine
Additional Challenges (Optional):
- Implement error handling for the route
- Explore and incorporate middleware functions
- Experiment with different response formats such as JSON or HTML
Hints:
- Use the npm package manager to install Express if it's not already installed.
- Utilize the
expressmodule to create an instance of the Express application. - Define a route using the
app.get()method and the specified path "/api/main". - Use the
res.send()method to send a descriptive response explaining the key features and benefits of using Express in web development.
