Integration with Bubble

Step 1: Import the specific data from Bubble to Xano

To get started with this integration, the first step is to import the users data from Bubble into Xano. There are two methods to do this smoothly:

‍

Method 1: Import CSV 

• Access the “Data” tab within Bubble and select the data set you want to export.
• Choose the "Export" option and select "CSV" as the export format.
• Then, go to Xano, access the "Database" tab and click "Add Table."
• Select the "Import" option and either drag and drop or browse for the CSV file you exported from Bubble.
• If you need to, review and customize the table schema, and then click "Upload" to import the data.

‍

Method 2: Bubble Data API

We recommend using this method when handling larger data sets and, since it will allow you to build an automated flow when importing data from Bubble to Xano. Let’s review the steps to follow:

• In Bubble, authorize the "Data API" under the "Settings" tab and copy the provided API root URL.
• In Xano, create a new API endpoint or function.
• Connect an "External API Request" function and paste the Bubble Data API root URL, and then the specific data set you want to import (e.g., `/companies`).
• Create a new table in Xano with the appropriate schema to match the data set you're importing.
• Use a "For Each" loop to iterate through the API response and connect the data to the correlative fields in your Xano table using the "Add Record" feature.
• This last step is optional, but you can convert the API endpoint to a function and schedule it as a background task in Xano to run periodically, ensuring your data stays synchronized.

‍

Step 2: Connecting Xano's API to Bubble

After conducting the process of moving your data to Xano, you will be able to connect Xano's API to Bubble, enabling seamless communication between the two platforms. Let’s review the steps to follow of this second and last step:

• First, install the "API Connector" plugin in Bubble.
• Add a new API and name it (e.g., "Xano").
• In Xano, copy the endpoint URL for the API you want to connect (e.g., `GET /companies` or `POST /companies`).
• In Bubble's API Connector, paste the copied URL and arrange any necessary headers or parameters.
• For `POST` requests, provide the request body with dynamic values mapped to the corresponding fields in your Xano data model.
• Save your changes, and then you are ready to start using Xano's API within your Bubble workflows and front-end logic.

Supabase

‍

Core features relevant to Bubble

Supabase is an open-source Firebase alternative, but instead of being built around a document-based datastore, it offers a relational database management system called PostgreSQL. As being a Firebase alternative, it shares some features with it, such as authentication, real-time database, and storage. However, as it is an open-source alternative, Supabase provides better and greater flexibility, and control over your data and applications.

If you are thinking about integrating Supabase with you Bubble app, let’s assess its core features and how they are relevant to your Bubble app:

‍

PostgreSQL database

Supabase provides a fully managed PostgreSQL database, which can be used as an external database for Bubble applications, allowing for more complex data structures and queries than Bubble's built-in database.

Real-time modifications

Supabase offers real-time features, which allows for conducting instant updates when any significant part of the data changes. This can be an advantage when integrating Supabase to Bubble since it can be handled to create Bubble applications that update in real-time without requiring page refreshes.

Authentication

Supabase provides built-in authentication services.This can be integrated with Bubble to handle user sign-ups, logins, and session management, potentially offering more advanced auth features than Bubble's native system.

Storage

Supabase includes object storage functionality. This can be used to store and serve files (like images, documents, etc.) for Bubble applications, potentially offering more flexibility or cost-effectiveness than Bubble's built-in storage.

REST API

Supabase automatically generates RESTful APIs for your database. This makes it easy to connect Bubble to your Supabase data using Bubble's API Connector or custom API calls.

‍

To integrate these features, you'd typically use Bubble's API Connector or JavaScript actions to interact with Supabase's APIs. The specific implementation would depend on your exact requirements and the features you want to leverage.

‍

Pros of Supabase

• Real-time database: Supabase offers real-time capabilities, allowing for instant updates.

• SQL support: Supabase offers a full PostgreSQL database, providing powerful querying options.

• Authentication: Built-in auth system, simplifying user management.

• Open-source: This offers more customizable and potentially cost-effective for large-scale projects.

• API auto-generation: Saves time in backend development.

‍

Cons of Supabase

• Learning curve: To establish a difference with Xano, Supabase’s learning curve is steeper, since it requires SQL knowledge to be able to set up DB and RLS policies correctly. 

• Integration complexity: In Supabase any logic has to be done using code.

• UI Issues: The UI presents an unrefined appearance and functionality, and issues may present within a short usage period.

‍

Performance and scalability

As we have reviewed, Supabase is designed to handle increasing loads and data volumes. Supabase is built on PostgreSQL, a strengthened and scalable open-source relational database system. PostgreSQL has strong capabilities for handling large data volumes and concurrent users, providing a solid foundation for Supabase's scalability. When assessing scalability, we should go through the platform’s horizontal scaling. This is, the ability to support adding more read replicas to distribute query load across multiple servers, which can significantly improve performance for read-heavy workloads. This is complemented by Supabase's use of PgBouncer for connection pooling, efficiently managing a large number of concurrent database connections.

To further enhance performance, Supabase implements various caching mechanisms, including Row Level Security (RLS) policy caching. This can reduce database load for frequently accessed data. Additionally, Supabase provides tools like PostgREST that automatically generate optimized SQL queries, helping to maintain performance as data volumes grow. It’s important to highlight that optimal performance at scale often requires careful database design, query optimization, and potentially some application-level optimizations.

Supabase's real time features are another factor in its ability to handle scale. These features use PostgreSQL's native replication system, which is designed to handle large-scale data changes efficiently. For users on Supabase's hosted platform, much of the scaling and optimization is handled behind the scenes, with automatic resource upgrades as needed.

‍

Cost of Supabase

Supabase offers four pricing plan options, starting from a free package to a large, customized enterprise tier. The free option supports simple websites, which allow up to 50,000 monthly active users. If you want to learn more about Supabase’s pricing plans, you can do it here!

‍

Integration with Bubble

There are two ways to integrate Supabase to Bubble: The first one consists in creating API calls directly on Bubble’s API Connector. The second option is installing the plugin. 

After you install the plugin, users have to fill out some basic data in order to connect to Supabase. The correct values can be obtained on the “Setting” section of the Supabase Dashboard, then click on the API tab.

After that first step is done, the second step is filling out both Public Keys in the plugin setting. This is an essential step for the integration to work properly. Once the page is correctly loaded, the Plugin will create a new “Client”, so that it can communicate with Supabase. This process will be executed for each element on the page, which is needed in order to create the API calls to Supabase for every process. The Project ID and the Anon Key will be pre-generated by Supabase when you create your project.

In order to create the Supabase URL, a RESTful endpoint will be created for querying and managing your database, which you can find in the API tab of your Supabase project Settings. Your Supabase Key, which is needed to be sent with every API request, and it's used to determine "anonymous" access to your Database based on RLS. You can find it in the “API tab” of your Supabase project Settings. The anon key is a JSON Web Token in itself, which will be used by Supabase to determine which data can the user access when they're not authenticated.

After these two steps, users will be able to use Supabase functions in their Bubble workflows. This includes operations like inserting, updating, or querying data. The creation of tables in Supabase that match your Bubble data structure, and the use of e Supabase as your backend database instead of Bubble's built-in database, is now possible. 

‍

Firebase

‍

Core features relevant to Bubble

Google developed Firebase as a comprehensive toolkit for building web and mobile applications. The platform offers several features relevant to Bubble, including realtime Database, Cloud Firestore, authentication, and Cloud Functions. The realtime database provides a NoSQL cloud database that synchronizes data in real-time across clients and supports offline functionality for mobile apps. Cloud Firestore offers more advanced querying capabilities and is designed for easier scaling. Firebase authentication supports multiple login methods, integrates seamlessly with other Firebase services, and handles user sessions and security. Cloud Functions, a serverless computing platform, allows developers to run backend code in response to events or HTTP requests, integrating with other Firebase and Google Cloud services. 

These features could potentially enhance Bubble's capabilities in areas such as real-time data synchronization, user authentication, and serverless backend logic, offering developers additional tools to create robust and scalable applications.

‍

Pros of Firebase

• Google support: As being a Google’s toolkit, Firebase benefits from Google Cloud and other Google tools and platforms that can help enhance the app development project.

‍

Cons of Firebase

• Closed source platform: Due to its closed-source architecture, Firebase doesn’t allow developers to have full control over the platform when building an app. This means that they won’t be able to modify Firebase’s code.

• No SQL database support: Firebase offers two databases, which are both NoSQL databases. This means that Firebase and Realtime databases cannot support relational database structures.

• Limited to Google Cloud: As Firebase is a Google toolkit, its infrastructure uses Google Cloud. Users who choose Firebase won’t be able to run on other cloud providers. 

‍

Performance and scalability

Firebase performance and scalability strengths lie in its real-time database and Cloud Firestore, which efficiently handle concurrent connections and high volumes of reads and writes. Firebase Cloud functions automatically scale based on demand, while its hosting uses a global CDN for quick content delivery. The platform's authentication system can manage millions of users, and its analytics are designed to process large data volumes. However, optimal performance often requires careful data structuring, especially for the real-time database. Some complex queries might be challenging, potentially impacting performance at scale. While Firebase can handle significant scale for many application types, particularly those benefiting from real-time updates, costs can increase substantially with high usage. Large-scale data migration can be challenging, and applications requiring many complex transactions might face limitations compared to traditional relational databases. 

‍

Cost of Firebase

Firebase offers a database-centric architecture, which means that as users scale their business to handle a larger number of simultaneous connections and real-time messaging between them , they will need to increase the database storage capacity. Firebase presents unwarranted rises in data storage expenses, since every modification that users perform into the database is disseminated to connected clients. Here is where users are encouraged to store every event that needs to be streamed to your users. The free plan offers only basic features that lack the advanced functions that simplify all development tasks. 

If you want to learn more about Xano’s pricing plans, you can do it here!

‍

Integration with Bubble

The first step to perform the integration is to create your Firebase project. So once you have created your account, you can start creating your project. Then, users need to set up their realtime database in Firebase. You can access that feature in the “Develop” section in the left menu. Choose the realtime database for a serverless NoSQL database. Click on Create Database in the real-time database section. Then, select a location for your Cloud Firestore. Take into consideration that this location would be used for all Firestore databases in your Firebase project.

After setting up a real-time database, click “Project Settings” and choose Service Accounts. Then, select Generate New Private Key, and confirm the prompt. A JSON file would be downloaded. Then, users are ready to access their Bubble account, or sign up if they don’t have one yet. From your user dashboard, click on New App, name it, check the boxes, and Create New App. Open your new app on your Bubble dashboard, and click on Plugins in the left sidebar. On the plugins page, click on Add Plugins, search and install the Firebase plugin by Zeroqode. After adding the plugin,  update the Api Key as private_key from the JSON file. Set Firebase url, where PROJECT_ID is also taken from the downloaded JSON file. Set Firebase User Email as client_email from the JSON file. Then, save the changes.

Finally, the Firebase plugin is configured and ready to be used in your Bubble app. Don’t forget to test all of its features to make sure the integration is working as expected.
