📋 Decision Context

Question:

Where should GoGrab Pulse store and serve MP3 audio files?

Task: GoGrab Pulse - Audio storage architecture

🎯 Decision Made

Chosen:

Cloudflare R2 object storage with r2.dev public access URLs

Options Considered:

  1. Cloudflare Pages (static deploy with MP3s)
  2. Cloudflare R2 object storage
  3. Traditional FTP server (gograb.space/pulse)
  4. Self-hosted CDN or S3

💭 Reasoning

R2 was chosen because: (1) Zero egress fees - streaming audio to many users costs nothing for bandwidth, unlike S3/GCS. (2) Built-in CDN delivery via r2.dev public URLs (format: pub-{hash}.r2.dev). (3) Separates large binary assets (MP3s, cover art) from the static site deploy on Cloudflare Pages, keeping deploys fast. (4) The R2 bucket is named 'gograb-pulse-music' and uses r2.dev managed public access (not custom domain). (5) Upload via CLI: npx wrangler r2 object put gograb-pulse-music/songs/{filename} --file={path} --remote --content-type=audio/mpeg. The --remote flag is CRITICAL - without it, wrangler uploads to local Miniflare instead of the cloud bucket. (6) The r2BaseUrl is stored in songs.json so the player knows where to stream from. (7) Cover art goes under the covers/ prefix in the same bucket. (8) FTP (gograb.space/pulse) was the original host but was deprecated after migrating to Cloudflare.
