Bring in modules from around the world into your Ionic framework built with Angular

While working with the ionic framework, I have noticed that many of my pages require the same modules.

import { Http } from '@angular/http';
import { Storage } from '@ionic/storage';

Therefore, I find myself setting them in the constructor on each page like this:

constructor(public navCtrl: NavController, public navParams: NavParams, public http: Http, private storage: Storage)

I am curious if there is a more efficient way to automatically include these modules on all my pages, or if what I am currently doing is the optimal solution.

Answer №1

Is there a more efficient way to automatically include these on all of my pages?

Unfortunately, there is not a better way. One suggestion could be to create a BasePage component where you can consolidate all the necessary imports and then simply import that BasePage into the other pages to inherit the properties. However, in terms of reducing duplication, it may not offer significant advantages unless you have numerous imports common across all pages or repeated code/methods utilized by each page. In such cases, placing this code in the BasePage would make sense.

If you are interested in exploring how this approach could be implemented, you can refer to this answer on Stack Overflow.

Therefore, if your constructor only requires a few imports and properties, what you're currently doing is likely the optimal solution.
