How to implement live updates in Bubble.io: Step-by-Step Guide

 

Before creating your live updates, identify which data in your app will change frequently and need to be updated for users instantly. For instance, this could be a list of messages in a chat app or real-time stock prices in a trading platform.
 

Bubble.io provides workflows that automatically run when certain events occur, for example, when a new entry is added to the database. You can set up workflows to trigger whenever relevant data changes. This could involve sending data to all connected users or updating a group’s content with the new information.
 

Custom states are temporary variables that can hold any type of data. You can use a custom state to store information that needs to be displayed live. For example, you might have a custom state for the latest message in a chat that updates each time a new message is sent.
 

Bubble’s dynamic expressions let you bind elements like text, image, or list directly to your database or custom states. If you bind a repeating group’s data source to a search for new messages, it will automatically update as new messages are added to the database.
 

Auto-binding allows elements like input fields to be directly connected to the database. When a user interacts with an auto-bound element, the changes are immediately saved to the database and subsequently, any other users viewing the data will see it update in real-time.
 

For data that doesn't need to be updated instantly but still fairly regularly (for example, every few seconds or minutes), use the "Do every X seconds" workflow event to refresh the data displayed to the user.
 

Once you have set up live updates, conduct extensive tests to ensure that changes are reflected in real-time across different user sessions. You can use Bubble.io’s preview mode to open multiple windows or use different browsers to mimic multiple users.
 

Live updates can cause additional database load and traffic, so it's important to design your database and workflows efficiently to handle this. Only update what is necessary and consider the scalability of your implementation.
