App Catalogue In SharePoint Online

Introduction

SharePoint App Catalog is the central location to publish our Apps and we can access the same across the site collection.

App Catalog is nothing but a site collection scoped at Application level, we can have only one App Catalog in the web application. You create the App Catalog site collection from SharePoint Central Administration or from Admin site in Office 365/Online.

Creating App Catalog

In this example I am going to create an App Catalogue in SharePoint Online, and I will be publishing my custom app in that App Catalogue. Once it’s published I am going to use same in a different site collection within the Web Application.

Steps to create App Catalog

1. Login to SharePoint Online admin site. We can login admin site using admin URL, here my site URL.
   
   
2. Select Apps menu in left side and create new App Catalogue in that.
   
   
   
   
   
   
   
   
3. Create new custom App using NAPA app and publish same in your site collection.
   
   
   
   
   
   
   
   
4. Download the app and upload to App Catalogue site collection.
   
   
   
   
5. Create another new site collection to access the App from App Catalogue.
   
   
   
   
   
   
6. Create Employee List in the site collection, (My custom App is going to fetch the employee records from this site collection employee list).
   
   
   
   
7. Add app from App Catalogue (by selecting from ‘From Your Organization’ left side menu),
   
   
   
   
   
   
8. Access the custom added app.
