Bloom Supabase Core

Supabase Core Functionality for Bloom

⚡ Quick Start

# Install dependencies
pnpm install

# Configure environment
cp .env.example .env.local
# Edit .env.local with your Parse Server credentials

# Start local development (requires Docker)
pnpm dev

# Run tests
pnpm test

Test the fs function:

curl "http://127.0.0.1:54321/functions/v1/fs/harvest/VuebFgcL0R/Ososi.bloompub" -o test.bloompub

📋 Prerequisites

• pnpm v11+ (pins its own version via packageManager and downloads Node.js v22.20.0 via devEngines.runtime in package.json — no Volta or manual Node install needed)
• Deno v2.9+ (runs and tests the edge functions)
• Docker Desktop (local development only)
• Supabase account

Dependency policy

Both package resolvers enforce a 7-day cooldown: a version published less than 7 days ago will not be installed (mitigates compromised-package supply-chain attacks).

• npm side (dev tooling): minimumReleaseAge in pnpm-workspace.yaml
• Deno side (edge function imports): minimumDependencyAge in deno.json

Dependencies are pinned to exact versions (savePrefix: "" for pnpm; exact versions in the deno.json import map), and CI installs with frozen lockfiles. To update deps, run pnpm update / deno outdated --update — both respect the cooldown — and commit the lockfile changes.

🗃️ fs Function

Streams book files from S3 without exposing bucket details.

URL: /functions/v1/fs/{bucket}/{bookid}/{path...}

Example:

# Get thumbnail
curl "http://localhost:54321/functions/v1/fs/dev-harvest/ZWI7FUQnDd/thumbnails/thumbnail-256.png"

# Download book (streams, no buffering)
curl "http://localhost:54321/functions/v1/fs/harvest/VuebFgcL0R/Ososi.bloompub" -o book.bloompub

# Range request
curl -H "Range: bytes=0-1023" "http://localhost:54321/functions/v1/fs/harvest/VuebFgcL0R/Ososi.bloompub"

🌐 Deployment

This project uses a staging → production deployment workflow:

Branching Strategy

• develop → Staging environment (auto-deploy on push)
• main → Production environment (auto-deploy on push)
• feature/* → Feature branches (PRs to develop)

Deployment Flow

1. Develop on feature branch
2. PR to develop → Runs tests
3. Merge to develop → Deploys to staging
4. Test in staging
5. PR from develop to main → Runs tests
6. Merge to main → Deploys to production

Manual Deploy

Actions tab → Choose workflow → Run workflow

See .github/workflows/README.md for complete documentation.
