Sutro Diosaur
A small dependency injection for Deno
Sutro Diosaur is a small dependency injection solution written in Typescript for Denowhich aims at making you write the minimum of code, avoiding obvious bindings and other repetitive stuff.
It’s a fork of the excellent diosaur, but with the non-Deno stuff taken out. In particular, it removes the reliance on reflect-metadata
since that isn’t fully supported in Deno.
Example
import {
Service,
Parameter,
Inject,
setParameter,
getContainer,
} from "diosaur";
@Service()
class Doggo {
constructor(@Parameter("doggoName") private name: string) {}
bark() {
return this.name.toUpperCase();
}
}
@Service()
class JonSnow {
@Inject({ identifier: Doggo })
private doggo: Doggo;
yell() {
return `I'm Jon with my doggo ${this.doggo.bark()} !`;
}
}
setParameter("doggoName", "Ghost");
const container = await getContainer();
const jon = container.get(JonSnow);
console.log(jon.yell());
The key difference here is the need to provide explicit identifiers for @Inject
