PocketBase

Overview

PocketBase is an open-source backend packaged as a single binary, providing an embedded SQLite database, real-time subscriptions, file storage, and built-in authentication. It auto-generates REST APIs for collections and is ideal for shipping full-stack applications with minimal infrastructure complexity.

Instructions

When defining collections, choose the appropriate type: base collections for standard CRUD, auth collections for user management with email/password and OAuth2, and view collections for read-only SQL-backed queries.
When building client integrations, use the JavaScript/TypeScript SDK with
```
pb.collection("name").getList()
```
for queries,
```
.subscribe()
```
for real-time updates, and
```
expand
```
parameter for fetching related data in a single request.
When configuring permissions, set API rules on every collection (
```
listRule
```
,
```
viewRule
```
,
```
createRule
```
,
```
updateRule
```
,
```
deleteRule
```
) using filter syntax like
```
@request.auth.id = user.id
```
for row-level security.
When extending functionality, add JavaScript hooks (
```
onBeforeCreateRecord
```
,
```
onAfterUpdateRecord
```
) for business logic, custom routes with
```
routerAdd()
```
, and cron jobs with
```
cronAdd()
```
.
When deploying, run the single binary with
```
./pocketbase serve
```
, mount
```
pb_data/
```
as a Docker volume, and use Caddy or Nginx for HTTPS termination.
When backing up, copy the
```
pb_data/
```
directory or use the built-in backup API before running migrations.
When scaling, note that SQLite handles approximately 50,000 concurrent reads; for write-heavy workloads exceeding 100K daily active users, consider PostgreSQL alternatives.

Examples

Example 1: Build an MVP backend with authentication

User request: "Set up a PocketBase backend with user auth and a posts collection"

Actions:

Create an auth collection for users with email/password and Google OAuth2
Create a posts collection with title, body, and relation to users
Set API rules: anyone can list/view, only authenticated authors can create/update/delete their own posts
Configure the JS SDK for client-side CRUD and auth flows

Output: A fully functional backend with auth, permissions, and auto-generated REST API.

Example 2: Add real-time features

User request: "Enable live updates for a chat application using PocketBase"

Actions:

Create a messages collection with text, sender relation, and room field

Set up SSE subscription with

pb.collection("messages").subscribe("*", callback)

Configure API rules for room-based access control
Handle client auto-reconnect with exponential backoff

Output: A real-time chat backend with live message delivery via Server-Sent Events.

Guidelines

Always set API rules on every collection; default is admin-only (
```
null
```
), which breaks client access.
Use
```
expand
```
parameter instead of multiple API calls for related data.
Validate inputs in hooks (
```
onBeforeCreateRecord
```
) for business logic beyond schema validation.
Back up
```
pb_data/
```
before migrations since SQLite migrations are irreversible.
Use view collections for complex queries instead of client-side joins.
Keep hooks lightweight; heavy processing should run async or in cron jobs.
