@sarahxc
Cron
Slack scout sends a slack notification every time your keywords are mentioned on Twitter, Hacker News, or Reddit. Get notified whenever you, your company, or topics of interest are mentioned online. Built with Browserbase . Inspired by f5bot.com . Full code tutorial . Getting Started To run Slack Scout, you’ll need a Browserbase API key Slack Webhook URL: setup here Twitter Developer API key Browserbase Browserbase is a developer platform to run, manage, and monitor headless browsers at scale. We’ll use Browserbase to navigate to, and scrape our different news sources. We’ll also use Browserbase’s Proxies to ensure we simulate authentic user interactions across multiple browser sessions . Get started with Browserbase for free here . Twitter We’ve decided to use the Twitter API to include Twitter post results. It costs $100 / month to have a Basic Twitter Developer account. If you decide to use Browserbase, we can lend our token. Comment below for access. Once you have the SLACK_WEBHOOK_URL , BROWSERBASE_API_KEY , and TWITTER_BEARER_TOKEN , input all of these as Val Town Environment Variables . Project created by Sarah Chieng and Alex Phan 💌

codeOnValTown
@andreterron
Script
Code on Val Town Adds a "Code on Val Town" ribbon to your page. This lets your website visitors navigate to the code behind it. This uses github-fork-ribbon-css under the hood. Usage Here are 2 different ways to add the "Code on Val Town" ribbon: 1. Wrap your fetch handler (recommended) import { modifyFetchHandler } from "https://esm.town/v/andreterron/codeOnValTown?v=50";
import { html } from "https://esm.town/v/stevekrouse/html?v=5";
export default modifyFetchHandler(async (req: Request): Promise<Response> => {
return html(`<h2>Hello world!</h2>`);
}); Example: @andreterron/openable_handler 2. Wrap your HTML string import { modifyHtmlString } from "https://esm.town/v/andreterron/codeOnValTown?v=50";
import { html } from "https://esm.town/v/stevekrouse/html?v=5";
export default async (req: Request): Promise<Response> => {
return html(modifyHtmlString(`<h2>Hello world!</h2>`));
}; Example: @andreterron/openable_html Other ways We made sure this was very modular, so you can also add the ribbon using these methods: Get the element string directly: @andreterron/codeOnVT_ribbonElement Modify an HTTP Response: @andreterron/codeOnVT_modifyResponse Use .pipeThrough to append to a stream: @andreterron/InjectCodeOnValTownStream Customization Linking to the val These functions infer the val using the call stack or the request URL. If the inference isn't working, or if you want to ensure it links to a specific val, pass the val argument: modifyFetchHandler(handler, {val: { handle: "andre", name: "foo" }}) modifyHtmlString("<html>...", {val: { handle: "andre", name: "foo" }}) Styling You can set the style parameter to a css string to customize the ribbon. Check out github-fork-ribbon-css to learn more about how to style the element. modifyFetchHandler(handler, {style: ".github-fork-ribbon:before { background-color: #333; }"}) modifyHtmlString("<html>...", {style: ".github-fork-ribbon:before { background-color: #333; }"}) Here's how you can hide the ribbon on small screens: modifyFetchHandler(handler, {style: `@media (max-width: 768px) {
.github-fork-ribbon {
display: none !important;
}
}`}) To-dos [ ] Let users customize the ribbon. Some ideas are the text, color or placement.

thisval
@begoon
Script
This val default exports a function returning ValInfo. The val information comes from the Deno stack trace induced by throw new Error() . type ValInfo = {
stack: string[]; // mostly for debugging
endpoint: string; // val endpoint URL, empty if it is not an HTTP val
user: string; // val.town user name
name: string; // val name
}; Here is an example program: import thisval from "https://esm.town/v/begoon/thisval";
const val = thisval();
export default async function(req: Request): Promise<Response> {
return Response.json(val);
} when invoked, it returns: {
"stack": [
"Error",
" at info (https://esm.town/v/begoon/thisval?v=12:10:11)",
" at https://esm.town/v/begoon/thisvaltest?v=2:3:13"
],
"endpoint": "begoon-thisvaltest.web.val.run",
"user": "begoon",

easyAQI
@stevekrouse
Script
easyAQI Get the Air Quality Index (AQI) for a location via open data sources. It's "easy" because it strings together multiple lower-level APIs to give you a simple interface for AQI. Accepts a location in basically any string format (ie "downtown manhattan") Uses Nominatim to turn that into longitude and latitude Finds the closest sensor to you on OpenAQ Pulls the readings from OpenAQ Calculates the AQI via EPA's NowCAST algorithm Uses EPA's ranking to classify the severity of the score (ie "Unhealthy for Sensitive Groups") It uses blob storage to cache the openai location id for your location string to skip a couple steps for the next time. Example usage @stevekrouse.easyAQI({ location: "brooklyn navy yard" })
// Returns { "aqi": 23.6, "severity": "Good" } Forkable example: val.town/v/stevekrouse.easyAQIExample Also useful for getting alerts when the AQI is unhealthy near you: https://www.val.town/v/stevekrouse.aqi
