pocketbase-presigned-urls
A PocketBase JSVM plugin that serves file uploads directly from S3 via pre-signed URLs, bypassing the PocketBase proxy.
Overview
pocketbase-presigned-urls is a JavaScript VM plugin for PocketBase that intercepts file download requests and redirects them to pre-signed URLs from S3-compatible storage. This approach offloads file serving from the PocketBase server to the object storage provider, improving performance and scalability for applications handling file uploads.
Key Features
- Direct S3 Serving — Redirects file requests to pre-signed S3 URLs, allowing downloads directly from the storage provider.
- Performance Optimization — Reduces server load and improves response times by avoiding proxying files through PocketBase.
- Configurable TTL — Allows setting a custom time-to-live for pre-signed URLs via the
PBPU_TTLenvironment variable. - Admin UI Compatibility — Includes options to control plugin behavior within the PocketBase admin interface using
PBPU_ADMIN_COMPAT. - AWS Signature V4 — Uses the standard AWS signing process to generate secure, temporary access URLs.
Philosophy
The plugin prioritizes scalability and performance by leveraging external object storage infrastructure for file delivery, adhering to the principle that dedicated storage services are more efficient for static asset serving than application server proxying.
