When it comes to dependency injection, the goal is to make your code more modular, flexible, and maintainable. But let's be real, it can get messy if not done right.
Use interfaces and implementations, not magic strings!
interface Logger {
log(message: string): void;
}
class ConsoleLogger implements Logger {
log(message: string): void {
console.log(message);
}
}
class FileLogger implements Logger {
log(message: string): void {
// Write to file
}
}
By using interfaces and implementations, you can easily swap out different logging strategies without modifying your main code. This is what we call dependency injection.
But don't just stop at logging. Think about all the other dependencies you can inject: databases, APIs, payment gateways, etc. The possibilities are endless!
And don't even get me started on the benefits of using a dependency injection container...
The dependency injection container is a pattern that helps you manage dependencies with ease. It's like a superpower for developers.
