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\nAgents can create an artifact by posting multipart form data to `/upload` with a\n`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, 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.",[155],"155fa63a-6c29-4628-a28f-bd81a3231a71","frontend","01a066e1-7df8-761e-a032-ed0a31d367a2",["D",1788432448946],"directory",[161],"2c726ff0-91cf-45d6-8074-ad59f1565f49","examples","01a066e1-7df8-761e-a032-d4d9bce1e62f",["D",1788432448946],[167],"4f360e5f-28ee-445f-9fdf-17ceb6edb283","backend","01a066e1-7df8-761e-a032-c6be217dfed8",["D",1788432448946],[172],"pulls","branches","forks","envVars",{"_183":67,"_185":67},"connections",{"_183":67,"_184":67},"count","unfilledCount","emptyCount",{"_47":171,"_37":172,"_35":173,"_145":-5,"_45":46,"_44":146,"_147":63,"_42":290,"_13":67,"_39":164,"_40":-5,"_29":30,"_151":-5,"_203":291,"_32":292},{"_47":283,"_37":284,"_35":285,"_145":173,"_45":46,"_44":146,"_147":63,"_42":286,"_13":67,"_39":213,"_40":287,"_29":30,"_151":-5,"_203":288,"_32":289},{"_47":276,"_37":277,"_35":278,"_145":173,"_45":46,"_44":146,"_147":63,"_42":279,"_13":67,"_39":213,"_40":280,"_29":30,"_151":-5,"_203":281,"_32":282},{"_47":166,"_37":167,"_35":168,"_145":-5,"_45":46,"_44":146,"_147":63,"_42":273,"_13":67,"_39":164,"_40":-5,"_29":30,"_151":-5,"_203":274,"_32":275},{"_47":266,"_37":267,"_35":268,"_145":168,"_45":46,"_44":146,"_147":63,"_42":269,"_13":67,"_39":26,"_40":270,"_29":30,"_151":-5,"_203":271,"_32":272},{"_47":259,"_37":260,"_35":261,"_145":168,"_45":46,"_44":146,"_147":63,"_42":262,"_13":67,"_39":26,"_40":263,"_29":30,"_151":-5,"_203":264,"_32":265},{"_47":252,"_37":253,"_35":254,"_145":168,"_45":46,"_44":146,"_147":63,"_42":255,"_13":67,"_39":26,"_40":256,"_29":30,"_151":-5,"_203":257,"_32":258},{"_47":160,"_37":161,"_35":162,"_145":-5,"_45":46,"_44":146,"_147":63,"_42":249,"_13":67,"_39":164,"_40":-5,"_29":30,"_151":-5,"_203":250,"_32":251},{"_47":242,"_37":243,"_35":244,"_145":162,"_45":46,"_44":146,"_147":63,"_42":245,"_13":67,"_39":213,"_40":246,"_29":30,"_151":-5,"_203":247,"_32":248},{"_47":235,"_37":236,"_35":237,"_145":162,"_45":46,"_44":146,"_147":63,"_42":238,"_13":67,"_39":213,"_40":239,"_29":30,"_151":-5,"_203":240,"_32":241},{"_47":228,"_37":229,"_35":230,"_145":162,"_45":46,"_44":146,"_147":63,"_42":231,"_13":67,"_39":213,"_40":232,"_29":30,"_151":-5,"_203":233,"_32":234},{"_47":221,"_37":222,"_35":223,"_145":162,"_45":46,"_44":146,"_147":63,"_42":224,"_13":67,"_39":213,"_40":225,"_29":30,"_151":-5,"_203":226,"_32":227},{"_47":217,"_37":38,"_35":36,"_145":162,"_45":46,"_44":14,"_147":63,"_42":218,"_13":67,"_39":26,"_40":41,"_29":30,"_151":-5,"_203":219,"_32":220},{"_47":209,"_37":210,"_35":211,"_145":162,"_45":46,"_44":146,"_147":63,"_42":212,"_13":67,"_39":213,"_40":214,"_29":30,"_151":-5,"_203":215,"_32":216},{"_47":154,"_37":155,"_35":156,"_145":-5,"_45":46,"_44":146,"_147":30,"_42":206,"_13":67,"_39":26,"_40":158,"_29":30,"_151":-5,"_203":207,"_32":208},{"_47":143,"_37":144,"_35":61,"_145":-5,"_45":46,"_44":146,"_147":30,"_42":202,"_13":67,"_39":149,"_40":150,"_29":30,"_151":152,"_203":204,"_32":205},["D",1788432448946],"children",[],[144],["D",1788432448946],[],[155],"40356ad0-42c7-4ec6-a16a-ec8be26057f6","upload.client.ts","01a066e1-7df8-761e-a032-eab935b29196",["D",1788432448946],"script","// Drag-and-drop / file-picker uploader for the dashboard, plus a small\n// confirm() for delete forms.
