PocketBase Guide: The Single-File Backend Solution
What is PocketBase?
In simple terms, PocketBase is an "all-in-one-file" backend solution.
Despite being lightweight, it comes with all the essentials:
- Database: Built-in SQLite, supporting relational data storage
- Real-time Subscriptions: Ability to receive data updates instantly, making it convenient for chat applications, real-time notifications, etc.
- User System: Includes registration, login, and permission management
- File Uploads: Can store images, documents, and more

Usage Guide
After installing the application, the first visit will prompt you to create an administrator account.
After logging in, you'll enter the main page.
Creating a Collection
Click "Collections" in the admin interface, then "New collection". For example, create a blog posts collection:
Suppose you want to build a personal blog, you would need:
- Article management
- User comments
- File uploads
With PocketBase, you can design it like this:
Collections:
- posts (Articles collection)
- title: Title
- content: Content
- slug: URL Slug
- featured_image: Featured Image
- comments (Comments collection)
- post: Relation to posts
- author: Relation to users
- content: Comment content
Top Right Area < /> API Preview: This feature is super useful!
Clicking it allows you to see the auto-generated API interface code for this collection. For frontend developers, this is extremely convenient. It shows you how to fetch, create, update, or delete user data via code, ready for copy-pasting, saving you the trouble of writing API documentation yourself.
Then the frontend can directly call the API:
You can view your operation logs in the logs section.
Using PocketBase to set up a backend, paired with a simple frontend, can get you up and running in a matter of days.
Honestly, PocketBase isn't a silver bullet. It might not be suitable for these scenarios:
- High Concurrency Scenarios: SQLite has limitations in handling concurrent requests.
- Complex Business Logic: If you need complex data processing, a professional backend framework might still be necessary.
- Large Team Collaboration: Lacks some enterprise-level features.
But for most small to medium-sized projects, it's genuinely sufficient.
Summary
The biggest advantage of PocketBase is that it's "sufficient and simple." It doesn't leave you feeling like features are missing, nor does it overwhelm you with complex configuration.
If you're looking for a lightweight yet fully-featured backend solution, I sincerely recommend giving PocketBase a try.
