Resumable upload sequence

✓Request or initialize an authenticated upload for the workspace.
✓Upload in 6 MB TUS chunks with retry delays and progress reporting.
✓Persist the media metadata only after storage confirms completion.
✓Reference the returned asset ID from a media route.
✓The public media endpoint serves only ready assets attached to active codes.

const upload = new tus.Upload(file, {
  endpoint: "https://<project>.storage.supabase.co/storage/v1/upload/resumable",
  chunkSize: 6 * 1024 * 1024,
  retryDelays: [0, 3000, 5000, 10000, 20000],
  headers: { authorization: `Bearer ${session.access_token}` },
  metadata: {
    bucketName: "linkcode-public-assets",
    objectName: `${userId}/${workspaceId}/${crypto.randomUUID()}`,
    contentType: file.type
  }
});
upload.start();

Large-file limits

LinkCode uses resumable delivery and records assets up to the configured product ceiling. The effective maximum is also constrained by the active Supabase Storage plan and project-wide setting.
