Introduction

Migrating your Bubble.io app’s backend from Bubble’s native database to an external database like Supabase can unlock powerful new possibilities for scalability, flexibility, and integration. This case study outlines a step-by-step approach for safely transitioning a Bubble database to Supabase with minimal risk and downtime, and it provides helpful strategies and resources to guide your migration. Whether you're looking to improve performance, handle larger datasets, or simply have more control over your data, this guide offers a comprehensive path forward.

Background: Why Migrate from Bubble’s Database?

While Bubble.io’s built-in database is convenient for rapid development, external databases like Supabase offer a wide range of advantages:

• Enhanced Scalability: With Supabase, you can handle larger datasets without the performance limitations that can arise with Bubble’s native database.
• Data Integrity and Security: Supabase provides advanced security features, including row-level security and data encryption.
• SQL Capabilities: Supabase is powered by PostgreSQL, allowing you to perform complex SQL queries and leverage robust data-handling features.

Given these benefits, many developers seek to migrate their apps to Supabase to enhance the backend without compromising Bubble’s no-code front end.

Step-by-Step Migration Strategy

Step 1: Plan and Organize

Define a clear migration plan to ensure your team has a shared understanding of each phase. Organize your database into functional areas, which will help you migrate components progressively while keeping the main app operational. Here’s a checklist to get started:

• Assess Your App’s Data Structure: Examine all tables, fields, and relationships to identify critical data components.
• Identify User Authentication Needs: Plan for user data migration separately to avoid disruption to user access.
• Create a Migration Timeline: Outline a timeline that accommodates testing, training, and unforeseen delays.

Tip: Plan B Backups can be a valuable resource to help you back up, analyze, and optimize your Bubble database.

Step 2: Set Up Supabase and Prepare Your Database

Sign up for Supabase and set up a new project. Supabase will provide you with an empty PostgreSQL database ready for migration. Perform initial housekeeping on your Bubble database to simplify migration:

• Rename Tables and Fields: Ensure tables and fields follow consistent naming conventions and are SQL-safe.
• Optimize Data Structure: Remove unused fields and streamline relationships in your Bubble database to make the migration cleaner.

Step 3: Practice Migration with Plan B Backups

Plan B Backups offers a quick way to copy Bubble data into Supabase. With one click, you can export all data and schema, including automatic creation of primary keys. Perform this initial migration to see how data translates from Bubble to Supabase.

• Export Data: Use Plan B to move data and schemas into Supabase, creating a base copy of your app data in the new database.
• Verify Structure: Check Supabase tables to ensure primary keys, relationships, and constraints are accurate.

Step 4: Create a Development Branch in Bubble

To make migration smoother, create a development branch within Bubble. This allows you to continue front-end development while maintaining a sync with your Supabase data migration.

• Branch Sync: Regularly sync this branch with your main Bubble app to keep changes aligned.
• Set Up Staging: If possible, set up a staging environment to test Supabase connections without affecting live data.

Step 5: Migrate Tables Incrementally

Migrate tables gradually, starting with simpler data tables that do not depend heavily on other tables. For example, tables for static or reference data (like lookup values) make excellent starting points.

• Connect Tables with Plugins: Use a plugin like No Code Garden to create CRUD (Create, Read, Update, Delete) components. Although documentation may be sparse, it is worth the time to learn and experiment with.
• Prototype Connections: Start with a simple table and test CRUD functionality in your Bubble app to confirm data flow and query accuracy.

Tip: By breaking the migration into manageable steps, you can continue to deliver a stable user experience without major disruptions.

Step 6: Implement User Authentication in Supabase

Bubble handles user authentication natively, while Supabase offers its own set of user management tools. Approach user migration as a separate task to ensure users experience no disruption during the transition.

• Parallel Authentication: Consider running Bubble and Supabase authentication in parallel, so users can log in seamlessly. Gradually migrate users to Supabase as they log in.
• Test Privacy Rules: Supabase provides row-level security and fine-grained access controls. Set up these rules to ensure data privacy and compliance.

Step 7: Complete CRUD Operations and Testing

As you migrate more tables, establish reusable components within Bubble to handle CRUD operations for Supabase tables. This approach minimizes duplication and makes the app more maintainable.

• Reusable Elements: Create reusable elements that encapsulate CRUD functionality for each table, allowing centralized updates.
• Testing: Verify data retrieval, form submissions, and user interactions thoroughly to catch any inconsistencies.

Step 8: Address Option Sets and Enumerated Types

Option sets in Bubble may need to be converted to enumerated types in Supabase, as Bubble’s option sets do not have a direct equivalent in Supabase.

• Enumerated Types: Use PostgreSQL enumerated types for fields that have a predefined set of values.
• Reference Tables: Alternatively, reference tables can be created in Supabase for values that are frequently updated.

Step 9: Final Migration and Go Live

Once the Supabase-backed functionality is thoroughly tested, perform a final data sync before taking the app live. You may need to briefly take the app offline to ensure data consistency.

• Final Sync: Use Plan B or custom scripts to perform a last data transfer from Bubble to Supabase.
• Update Database Connection: Adjust your Bubble app settings to rely exclusively on Supabase.
• Go Live: Re-enable the app, now fully backed by Supabase.

Tip: Ensure that all elements referencing Bubble tables now point to Supabase.

Conclusion

Migrating a Bubble app to Supabase doesn’t have to be a daunting process. With careful planning, incremental steps, and the right tools, you can enhance your app’s backend capabilities while keeping risks and downtime low. A Supabase backend enables better data handling, greater control, and scalability, ensuring your Bubble app is prepared for future growth.
