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.",[],[75],"d7f9be9e-b52f-4fac-a791-c3a9eea8781e","frontend","84591506-8494-4a4c-bb02-86fe0fa9f7ec",4,["D",1781376794906],0,"directory",[92,93,94,95,96],[84],{"_33":131,"_13":132,"_36":133,"_38":85,"_40":41,"_42":134,"_44":45,"_46":135,"_17":136,"_49":103,"_50":137,"_52":53,"_54":-5,"_71":138,"_18":139},{"_33":123,"_13":124,"_36":125,"_38":85,"_40":41,"_42":126,"_44":45,"_46":127,"_17":112,"_49":103,"_50":128,"_52":53,"_54":-5,"_71":129,"_18":130},{"_33":116,"_13":117,"_36":118,"_38":85,"_40":41,"_42":86,"_44":45,"_46":119,"_17":88,"_49":103,"_50":120,"_52":53,"_54":-5,"_71":121,"_18":122},{"_33":107,"_13":108,"_36":109,"_38":85,"_40":41,"_42":110,"_44":45,"_46":111,"_17":112,"_49":103,"_50":113,"_52":53,"_54":-5,"_71":114,"_18":115},{"_33":97,"_13":98,"_36":99,"_38":85,"_40":41,"_42":100,"_44":45,"_46":101,"_17":102,"_49":103,"_50":104,"_52":53,"_54":-5,"_71":105,"_18":106},"f68fe9d8-9a49-4926-a99d-b065f19e3d34","upload.client.ts","38b33616-6759-11f1-ad57-1607ee4eb77e",30,["D",1786048234784],3,"script","// Drag-and-drop / file-picker uploader for the dashboard, plus a small\n// confirm() for delete forms.
