Drop an `.html` or `.md` file onto\nthe dashboard and get a link you can send to your team.\n\n**Live demo:** https://artifacts-demo.val.run/\n\nClick **Remix** to get your own isolated copy.\n\n## What you get\n\n- A dashboard that lists every artifact and supports drag-and-drop uploads.\n- **HTML and Markdown** support — HTML is served as-is; Markdown becomes a\n clean, readable page.\n- Rename artifacts and see who uploaded each one.\n- **Team-only:** Orgs can enable restricted access so only designated team\n members can access the page, behind a Val Town login with a single click.\n- Artifact contents in this val's **blob storage**, with searchable metadata in\n SQLite.\n- Each artifact rendered in a **sandboxed iframe**, so its scripts can't act as\n the viewer.\n- Example artifacts to start — delete them whenever.\n\n## Access\n\nThe app is public by default. An org should enable **restricted access** in Val\nTown to put the whole app behind Val Town login and choose which team members\ncan open it. Because Val Town applies the gate before the request reaches\n`main.tsx`, every page and action is covered without callback routes, secrets,\nor app-level auth code.\n\nIf you leave access public, anyone with the URL can view, upload, rename, and\ndelete artifacts.\n\n## Creating artifacts\n\nOpen `/dashboard`, then drag in an `.html`, `.htm`, `.md`, or `.markdown` file.\nThe format is detected from the extension and the artifact gets a short URL such\nas `/a/3fa9c21b1e`.\n\nOn a restricted app, Val Town supplies the uploader's username through its\nsigned viewer identity. Public and automation-bypass uploads are recorded as\n`anonymous`.\n\n## Programmatic API\n\nThe `/api/*` routes let you upload and list artifacts from a script, CI, or\nanother val. They're gated behind an API key set as the `ARTIFACTS_API_KEY`\nenvironment variable — without it they answer `401`. Send the key as a\n`Bearer` token or an `x-api-key` header:\n\n```bash\nKEY=your-secret\nBASE=https://.val.run\n\n# Create an artifact from a file (multipart, like the UI)\ncurl -X POST \"$BASE/api/artifacts\" -H \"Authorization: Bearer $KEY\" -F \"file=@./report.html\"\n\n# Create one from a raw string (JSON)\ncurl -X POST \"$BASE/api/artifacts\" \\\n -H \"Authorization: Bearer $KEY\" -H \"Content-Type: application/json\" \\\n -d '{\"html\":\"

hi

\",\"name\":\"release\",\"kind\":\"html\"}'\n\n# List all artifacts (metadata only)\ncurl \"$BASE/api/artifacts\" -H \"Authorization: Bearer $KEY\"\n```\n\n`POST /api/artifacts` returns `201` with `{ \"id\", \"url\" }` (an absolute URL);\n`GET /api/artifacts` returns the artifact list. The browser UI's `/upload`\nroute is unchanged and stays open.\n\n## How it works\n\n```\nmain.tsx Hono routes (the HTTP entry)\nbackend/\n db.ts SQLite metadata + val-scoped blob contents\n render.ts Markdown → HTML; HTML passes through as-is\nfrontend/\n Layout.tsx HTML shell\n Landing.tsx overview and dashboard link\n Dashboard.tsx list, upload, rename, and delete artifacts\n Viewer.tsx sandboxed iframe for one artifact\n upload.client.ts drag-and-drop browser script\nexamples/ seed artifacts\n```\n\n## Storage\n\nSQLite stores each artifact's id, name, kind, blob key, uploader, and creation\ntime. The uploaded source lives under the `artifacts/` prefix in this val's\nproject-scoped blob storage. New remixes therefore start with isolated data.\n\n## Security model\n\nArtifacts are untrusted content, including Markdown that contains raw HTML:\n\n- They render in an iframe without `allow-same-origin`. JavaScript can run, but\n it cannot read the app's cookies or call app routes as the viewer.\n- `/a/:id/raw` also sends `Content-Security-Policy: sandbox`, so opening it\n directly keeps the same opaque-origin boundary.\n- Markdown goes through the same sandbox as uploaded HTML.\n\nIf the app is restricted, anyone allowed through the Val Town access gate can\nupload, rename, and delete artifacts.",[],[205],"084d3e5b-7141-4487-98a9-1d5a73eff7ee","upload.client.ts","01a01be0-4032-74fe-b778-9054966e8bd4","01a01be0-4032-74fe-b778-9660538c09f1",["D",1787174076294],"script","// Drag-and-drop / file-picker uploader for the dashboard, plus a small\n// confirm() for delete forms.
