Beginning in November, Microsoft will begin rolling out to new features in SharePoint Modern Libraries:

• Microsoft PowerApps – rapidly build web and mobile business applications without coding
• Microsoft Flow – automate business processes through simple configuration

This means:

• You’ll be able to launch PowerApps directly from the SharePoint mobile app.
• Modern document libraries will be made available as a data source for PowerApps and Microsoft Flow.
• For Microsoft Flow, you’ll be able to run any flow on demand for a specific document or list item, in addition to waiting for an automated trigger to fire.
• Using the data gateway, PowerApps and Microsoft Flow will work with on-premises data in SQL and SharePoint as simply as cloud-based data.
