}Publish a browser game or any other page made to play or use on Velven's hosting, from one HTML page or a small set of files (3 MB in all). Signed in: a private preview by default, or with prod: true the next live version, live on its Velven page within seconds. Not signed in: an unlisted page, live the same way, returned with a claim token that keeps it. A new space needs title and devices from the person. To update a space pass space (signed in) or claim (not signed in).
| Argument | Type | Description |
|---|---|---|
| sdk | boolean | Add Velven's SDK script to the entry page. Default true. |
| spa | boolean | Serve the entry page for any unknown path (a single-page app). |
| clip | string | The video the tile plays on hover, without sound. Give the path of one of the files sent: an MP4 or WebM, up to 3 MB and 5 to 10 seconds long. Velven then records no clip of its own. Without a thumbnail, the clip's first frame is the picture. It must show the space itself. A clip outside that length is refused. If the file doesn't say its length, Velven measures it once live. It keeps the first 10 seconds of a longer clip, and drops a shorter one. A later version that names neither keeps the space's. |
| html | string | A whole page as one HTML string, published as index.html. |
| prod | boolean | Go live on the space's Velven page instead of making a preview. Signed in only. Default false. |
| claim | string | The claim token of an unlisted page: publishes its next version, or claims it when signed in. |
| entry | string | The page that opens first, if not index.html. |
| files | object | Files by relative path: text as a string, binary as { "base64": "..." }. Must include the entry page (index.html unless entry says otherwise). A velven.json, a dotfile, a dot-folder or node_modules, in any folder, is left out (never published; the result names the first 10 and counts the rest): send velven.json's settings as this tool's fields. |
| space | string | Publish a new version of this space (yours, signed in). |
| title | string | The space's name. Required for a new space. |
| engine | string | What it draws with, if one of these. |
| devices | array | Where it can be played. Required for a new space. |
| thumbnail | string | The picture on the space's tile. Give the path of one of the files sent: a JPEG, PNG or WebP, up to 2 MB and 4096 pixels on each side. It's used as soon as the version is live, and Velven takes no picture of its own. It must show the space itself. |
| description | string | One line under the name. |
