What to build

Set up an S3-compatible Cloudflare R2 bucket (titik-gambut-tiles) for zero-egress static tile distribution. Create an automated sync script to upload all compiled .pmtiles archives and asset bundles with correct MIME headers.

Technical specifications

  1. Target files:
    • scripts/sync-tiles-r2.sh: R2 upload script using AWS CLI / MinIO Client / rclone.
    • .env.example: Add R2 endpoint, access key, secret key, and public tile bucket URL configurations.
  2. Metadata headers:
    • Content-Type: application/x-protobuf for .pmtiles files.
    • Content-Type: image/tiff for .tif COGs.
    • Cache-Control: public, max-age=31536000, immutable.

Acceptance criteria

  • Script successfully uploads all .pmtiles archives to the R2 bucket.
  • Public HTTP range request to the bucket returns 206 Partial Content with valid byte length.
  • Zero egress fees incurred on range reads.

Blocked by

  • Issue 21: [Backend] Unified multi-layer PMTiles batch builder script.
