Ephemeral Links\n\nA small Val Town shortener that creates self-destructing links backed by Val Town SQLite.\n\n## Behavior\n\n- `GET /` renders the landing page and simple API docs.\n- `POST /` accepts either `application/json` or URL-encoded form data with a `url` field.\n- `GET /:code` redirects to the original URL while the record is still valid.\n- Links expire automatically after 48 hours; expired records are purged on create/read.\n\n## Files\n\n- `main.ts` — request handler, SQLite schema, HTML responses, and redirect logic.\n- `style.css` — stylesheet served from `/style.css`.\n\n## Storage\n\nThe val stores short-link records in Val Town SQLite using the `short_links` table.\nNo extra environment variables are required.\n\n## Local workflow\n\nFrom `vals/`:\n\n```bash\ndeno task check\n```\n\nFrom `vals/ephemeral-links/`:\n\n```bash\nvt status\nvt push --dry-run\n```\n","createdAt",["D",1775520275853],"branchVersion","branchId","d0b08be8-1ff7-11f1-a7e1-42dde27851f2","id","d0afced8-1ff7-11f1-a7e1-42dde27851f2","ephemeral-links",["D",1773528464375],"deletedAt","legacyEnvVars","privacy","public","httpPrivacy","description","Short
