To create a simple HTTP server in Go (Golang), you can use the built-in net/http
package. Here's a basic example:
Explanation:
- Package Import: We import
fmt
for formatting andnet/http
for HTTP server functionalities. - Handler Function: The
handler
function writes "Hello, World!" to the response. - Main Function: We set up the route and start the server on port 8080.
Differences from JavaScript in Backend Development:
- Concurrency: Go has built-in support for concurrency with goroutines, making it easier to handle multiple requests simultaneously compared to JavaScript's event-driven model.
- Static Typing: Go is statically typed, which can help catch errors at compile time, while JavaScript is dynamically typed.
- Performance: Go generally offers better performance for CPU-bound tasks due to its compiled nature.
This simple server is a great starting point for understanding how to build web applications in Go!
