Providers

You can use ctx.providers to store providers (for dependency injection). This allows to easily swap out providers (say switching caching service, image host, etc):

const users = {
  getUser(id) {
    // ...
  },
};

const app = new Routex({
  providers: {
    users,
  },
});

app.get("/", (ctx) => {
  const user = ctx.providers.users.getUser(1);
  return new JsonBody({ user });
});

You can also inject new providers in middlewares (the root providers will not be mutated):

const app = new Routex({
  providers: {
    users,
  },
});

app.middleware((ctx) => {
  ctx.providers.images = {
    getImage(id) {
      // ...
    },
  };
});

app.get("/", (ctx) => {
  const user = ctx.providers.users.getUser(1);
  const image = ctx.providers.images.getImage(1);
  return new JsonBody({ user, image });
});
