Vercel doesn't have a single, built-in migration system but instead relies on standard, database-specific tools. For relational databases like Vercel Postgres, you use traditional ORMs or migration libraries. For key-value stores like Vercel KV, migration is typically a manual process of data transformation.
Vercel provides a streamlined way to integrate databases into your projects, focusing on a serverless and edge-centric approach. Instead of a single database, Vercel offers a suite of storage solutions, each optimized for different use cases. The integration process is designed to be seamless, with first-class support for a range of serverless databases [1].
No, SQLite is not officially supported by Vercel for production applications because of its reliance on the local filesystem. Vercel's serverless functions are stateless and run in a read-only environment, meaning any changes to the local filesystem are discarded after the function's execution. This makes it impossible to persist the SQLite database file between function invocations. Vercel source
While you might be able to get a read-only SQLite database to work by including the database file in your deployment bundle, any attempt to write to it will fail. This limitation makes SQLite unsuitable for most dynamic web applications on the Vercel platform.
Vercel provides a suite of data storage solutions designed to complement its serverless and edge-first architecture. Instead of a single "Vercel Database," you get a selection of tools, each optimized for a specific use case. This allows you to choose the right database for the job, whether it's a simple key-value store or a full relational database.
Yes, you can define your own custom PostgreSQL roles and use them with RLS in Supabase. This is a powerful feature for implementing sophisticated Role-Based Access Control (RBAC) [1, 2].
The key is to understand that Supabase's built-in auth.uid() function and authenticated role are tied to the user's session. To use custom roles, you need to store this role information and make it accessible to your RLS policies.
There is minimal vendor lock-in with Supabase. The platform is designed to be as open as possible, leveraging established, open-source technologies. This makes it relatively easy to migrate away from their managed service if needed.
Supabase is built on a standard PostgreSQL database, giving you the flexibility to interact with it using various tools and methods. This guide explores how to integrate with Supabase, extend its functionality, and choose the right method for different tasks.
Supabase provides powerful, built-in tools to help you identify and diagnose slow queries. The key is to leverage the pg_stat_statements extension, which is enabled by default on all Supabase projects [1, 4].
Building robust applications requires more than just a functional database; it requires a disciplined approach to managing changes, testing, and deployment. This guide will focus on the DevOps side of Supabase, explaining how to handle database migrations, integrate with CI/CD pipelines, and manage test data.
Here are detailed answers and a guide on how Supabase's Real-time, Auth, and RLS policies work together to secure your application.
