asciiNycCameras
@maxm
HTTP (deprecated)
ASCII NYC Traffic Cameras All of NYC's traffic cameras available as streaming ASCII images: https://maxm-asciinyccameras.web.val.run/ NYC has a bunch of traffic cameras and makes them available through static images like this one . If you refresh the page you'll see the image update every 2 seconds or so. I thought it might be fun to make these cameras viewable as an ASCII art video feed. I made a small library that takes most of its logic from this repo . You can see a basic example of how to convert any image to ASCII here . I pull in NYC GeoJSON from here and then hook up a Server-Sent Events endpoint to stream the ASCII updates to the browser. (Polling would work just as well, I've just been on a bit of a SSE kick lately.) Hilariously (and expectedly) The ASCII representation is about 4x the size of the the source jpeg and harder to see, but it has a retro-nostalgia look to it that is cool to me :)

@pomdtr
HTTP (deprecated)
Val town by example Usage Simple Example To add an example, just create a val.
The val should start with a JSDoc style multi line comment that describes the example: /**
* @title HTTP server: Hello World
* @description An example of a HTTP server that serves a "Hello World" message.
*/
// this comment will be displayed on the left
export const server = () => new Response("Hello world!") The title is required. Then, you can write the code.
Code can be prefixed with a comment that describes the code.
The comment will be rendered next to the code in the example page. Make sure your val is public, then go to https://pomdtr-val_town_by_example.web.val.run/v/<your-username>/<your-val> Using multiple vals You can add another val to your example by adding an @include directive /**
* @title HTTP server: Hello World
* @description An example of a HTTP server that serves a "Hello World" message.
* @include pomdtr/secondary_val
*/ See @pomdtr/react_example Adding external resources to your example You can attach an external link to your val by using the @resource directive. External resources are specified using a markdown link. /**
* @title HTTP server: Hello World
* @description An example of a HTTP server that serves a "Hello World" message.
* @resource [Val Town Docs](https://docs.val.town)

static
@pomdtr
HTTP (deprecated)
Static Vals Serve static content from val.town Usage First, fork this val to get your own http endpoint. Then create a val that uses a string as it's default export, or a single string export. The val must be either public or unlisted . export default `<static content>` You can then fetch the exported string from outside val.town using: curl 'https://<owner>-static.web.val.run/<val>.<extension>' The Content-Type will be dynamically set depending on the provided extension.
