Drop an `.html` or `.md` file onto the 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 clean, readable page.\n- **Team-only:** Orgs can enable restricted access so only designated team members can access the page, behind a Val Town login.\n- Artifact contents in this val's **blob storage**, with searchable metadata in SQLite.\n- Each artifact rendered in a **sandboxed iframe**, so its scripts can't act as the viewer.\n- Example artifacts to start — delete them whenever.\n\n## Access (currently beta)\n\nThe app is public by default. An org can enable **restricted access** in Val Town to put the whole app behind Val Town login and choose which team members can open it. Because Val Town applies the gate before the request reaches `main.tsx`, every page and action is covered without `std/oauth`, callback routes, secrets, or app-level auth code.\n\nIf you leave access public, anyone with the URL can view, upload, and delete artifacts.\n\n## Creating artifacts\n\nOpen `/dashboard`, then drag in an `.html`, `.htm`, `.md`, or `.markdown` file. The format is detected from the extension and the artifact gets a short URL such as `/a/3fa9c21b1e`.\n\nAgents can create an artifact by posting multipart form data to `/upload` with a `file` field. A `kind` field can explicitly select `html` or `md`.\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, 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| Route | What |\n|---|---|\n| `GET /` | overview |\n| `GET /dashboard` | list and upload artifacts |\n| `POST /upload` | create an artifact |\n| `GET /a/:id` | view an artifact in a sandbox |\n| `GET /a/:id/raw` | rendered artifact HTML loaded by the iframe |\n| `POST /a/:id/delete` | delete an artifact |\n| `GET /source` | open this val's source |\n\n## Storage\n\nSQLite stores only metadata: id, name, kind, blob key, and creation time. The uploaded source lives under the `artifacts/` prefix in this val's project-scoped blob storage. New remixes therefore start with isolated data.\n\nWhen this version first runs over an older copy, it moves existing source out of `artifacts_v1` into blobs and removes the legacy table after all rows have been copied.\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 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 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 upload and delete artifacts.\n\n## Next steps\n\n- Restyle the landing page in `frontend/Landing.tsx`.\n- Add tags or search to the SQLite metadata in `backend/db.ts`.\n",[149],"d7f9be9e-b52f-4fac-a791-c3a9eea8781e","frontend","84591506-8494-4a4c-bb02-86fe0fa9f7ec",["D",1781376794906],"directory",[156],"2fa6191b-d9b0-4c7f-9b74-c9c251974fd4","examples","ca0933b3-789a-40c6-8923-e18152bc131c",11,["D",1781376837253],[162],"f21e7a0a-9b8d-4e09-be62-f7880b77ea61","backend","8e92c53c-11df-463e-aac7-0a8b38124988",3,["D",1781376790297],[168],"pulls","branches",1,"forks",2,"envVars",{"_182":63,"_184":63},"connections",{"_182":63,"_183":63},"count","unfilledCount","emptyCount",{"_43":167,"_32":168,"_30":169,"_138":-5,"_41":42,"_40":170,"_140":25,"_38":290,"_13":63,"_34":159,"_36":-5,"_24":49,"_145":-5,"_201":291,"_27":292},{"_43":282,"_32":283,"_30":284,"_138":169,"_41":42,"_40":285,"_140":49,"_38":286,"_13":142,"_34":35,"_36":287,"_24":49,"_145":-5,"_201":288,"_27":289},{"_43":275,"_32":276,"_30":277,"_138":169,"_41":42,"_40":259,"_140":25,"_38":278,"_13":63,"_34":35,"_36":279,"_24":49,"_145":-5,"_201":280,"_27":281},{"_43":161,"_32":162,"_30":163,"_138":-5,"_41":42,"_40":164,"_140":25,"_38":272,"_13":63,"_34":159,"_36":-5,"_24":49,"_145":-5,"_201":273,"_27":274},{"_43":264,"_32":265,"_30":266,"_138":163,"_41":42,"_40":267,"_140":25,"_38":268,"_13":63,"_34":20,"_36":269,"_24":49,"_145":-5,"_201":270,"_27":271},{"_43":256,"_32":257,"_30":258,"_138":163,"_41":42,"_40":259,"_140":25,"_38":260,"_13":63,"_34":20,"_36":261,"_24":49,"_145":-5,"_201":262,"_27":263},{"_43":249,"_32":250,"_30":251,"_138":163,"_41":42,"_40":164,"_140":49,"_38":252,"_13":63,"_34":20,"_36":253,"_24":49,"_145":-5,"_201":254,"_27":255},{"_43":155,"_32":156,"_30":157,"_138":-5,"_41":42,"_40":142,"_140":25,"_38":246,"_13":63,"_34":159,"_36":-5,"_24":49,"_145":-5,"_201":247,"_27":248},{"_43":238,"_32":239,"_30":240,"_138":157,"_41":42,"_40":241,"_140":49,"_38":242,"_13":170,"_34":35,"_36":243,"_24":49,"_145":-5,"_201":244,"_27":245},{"_43":230,"_32":231,"_30":232,"_138":157,"_41":42,"_40":233,"_140":49,"_38":234,"_13":175,"_34":35,"_36":235,"_24":49,"_145":-5,"_201":236,"_27":237},{"_43":223,"_32":224,"_30":225,"_138":157,"_41":42,"_40":142,"_140":25,"_38":226,"_13":63,"_34":35,"_36":227,"_24":49,"_145":-5,"_201":228,"_27":229},{"_43":215,"_32":216,"_30":217,"_138":157,"_41":42,"_40":218,"_140":49,"_38":219,"_13":175,"_34":35,"_36":220,"_24":49,"_145":-5,"_201":221,"_27":222},{"_43":207,"_32":208,"_30":209,"_138":157,"_41":42,"_40":210,"_140":25,"_38":211,"_13":170,"_34":35,"_36":212,"_24":49,"_145":-5,"_201":213,"_27":214},{"_43":148,"_32":149,"_30":150,"_138":-5,"_41":42,"_40":151,"_140":49,"_38":204,"_13":142,"_34":20,"_36":153,"_24":49,"_145":-5,"_201":205,"_27":206},{"_43":136,"_32":137,"_30":58,"_138":-5,"_41":42,"_40":139,"_140":49,"_38":200,"_13":142,"_34":143,"_36":144,"_24":49,"_145":146,"_201":202,"_27":203},["D",1786048149865],"children",[],[137],["D",1786048235500],[],[149],"f68fe9d8-9a49-4926-a99d-b065f19e3d34","upload.client.ts","38b33616-6759-11f1-ad57-1607ee4eb77e",30,["D",1786048234784],"// Drag-and-drop / file-picker uploader for the dashboard, plus a small\n// confirm() for delete forms.
