Key features of injection-js include:
- Support for various dependency injection methods, such as constructor injection, setter injection, and method injection.
- Multiple dependency lookup methods, including type-based and name-based lookup.
- Customizable dependency resolvers.
injection-js is designed for developers who need to implement dependency injection in JavaScript applications. It finds applications in various scenarios:
- Complex JavaScript Applications: Ideal for dependency injection in complex JavaScript applications.
- Test-Driven Development (TDD): Suitable for TDD practices involving dependency injection.
Developers can tailor the use of injection-js to meet their specific requirements.
To utilize injection-js effectively in your JavaScript project, follow these steps:
// Install injection-js
npm install injection-js
// Import injection-js
import { inject } from "injection-js";
// Create dependencies
class Foo {
constructor(bar) {
this.bar = bar;
}
sayHello() {
return `Hello, ${this.bar.name}`;
}
}
class Bar {
constructor(name) {
this.name = name;
}
}
// Use dependency injection
const foo = inject(Foo, {
bar: Bar,
});
console.log(foo.sayHello()); // Hello, world
Please exercise caution while using the code. For further details, refer to the documentation.
In summary, injection-js simplifies the implementation of dependency injection in JavaScript applications, offering a feature-rich solution with customizable dependency injection methods and lookup options.
