Twitter/𝕏 keyword alerts Custom notifications for when you, your company, or anything you care about is mentioned on Twitter. If you believe in Twitter/𝕏-driven development, you want to get notified when anyone is talking about your tech, even if they're not tagging you. To get this Twitter Alert bot running for you, fork this val and modify the query and where the notification gets delivered. 1. Query Change the keywords for what you want to get notified for and the excludes for what you don't want to get notified for. You can use Twitter's search operators to customize your query, for some collection of keywords, filtering out others, and much more! 2. Notification Below I'm sending these mentions to a public channel in our company Discord, but you can customize that to whatever you want, @std/email, Slack, Telegram, whatever. Twitter Data & Limitations The Twitter API has become unusable. This val gets Twitter data via SocialData , an affordable Twitter scraping API. In order to make this val easy for you to fork & use without signing up for another API, I am proxying SocialData via @stevekrouse/socialDataProxy. Val Town Pro users can call this proxy 100 times per day, so be sure not to set this cron to run more than once every 15 min. If you want to run it more, get your own SocialData API token and pay for it directly.

This is a very simple template for the kind of Bluesky bot I build. It's very much all over the place. e.g. it sets up the "Agent" to post (because that part is documented well), but doesn't use it to search for posts. You can do that if you want (if you do, look here ), but I like to simply rawdogg the API, so that is what I'm doing here. The custom Post type is incomplete and only contains the stuff I found relevant. Error handling is payed only lip service to (at best) as well. ...But it works for me! How to use If you want to use this, you will have to set 2 environment variables for your val: BLUESKY_USERNAME BLUESKY_PASSWORD From what I can tell from my testing: BLUESKY_USERNAME can be both the bot account's handle as well as the email you use to log into it with. BLUESKY_PASSWORD can be both the account's main password as well as an app password. The rest is commented in the code. If you have any questions, feel free to message me on Bluesky: Jonas-Merlin Schumacher (@jonasmerlin.bsky.social) — Bluesky

Password Auth Middleware Protect your vals behind a password. Use session cookies to persist authentication. Usage import { passwordAuth } from "https://esm.town/v/pomdtr/password_auth?v=84"; export default passwordAuth(() => { return new Response("OK"); }, { verifyPassword: (password) => password == Deno.env.get("VAL_PASSWORD") }); If you want to use an api token to authenticate: import { passwordAuth } from "https://esm.town/v/pomdtr/password_auth?v=84"; import { verifyToken } from "https://esm.town/v/pomdtr/verifyToken"; export default passwordAuth(() => { return new Response("OK"); }, { verifyPassword: verifyToken }); TODO [x] allow to authenticate using a val town token [ ] add a way to send an email to ask a password from the val owner [ ] automatically extend the session [ ] automatically remove expired sessions FAQ How to sign out ? Navigate to <your-site>/signout .

New Stripe Subscription Handler This val processes new Stripe subscribers to Val Town Pro. It sends our team a Discord notifcation and sends a welcome email to the new subscriber. It takes a couple of steps if you'd like to set up something similar for your own Stripe account. Setup Fork this HTTP val Create a new webhook in Stripe Add your val's HTTP endpoint URL into the Stripe webhook Select customer.subscription.updated as the only event to listen to (more on this below) Add your stripe_sk_customer_readonly to your Val Town Env Variables Add your webhook's signing secret as STRIPE_WEBHOOK_SECRET to you Val Town Env Variables How the code is structured Verifies the signature to make sure it's really from Stripe Filters out only newly created subscriptions Sends off the Discord message & email Which Stripe event type to listen to Stripe sends webhooks for many different kinds of events. Relevant for us here are: customer.subscription.created (what we used to listen for) customer.subscription.updated (what we're currently listening for) The issue with customer.subscription.created is that it triggers too early, before the user's payment actually goes through. This is a problem because in early Nov 2024 we started getting credit card fraudsters testing cards using our service. We started getting lots of notifications for new subscriptions that never actually became active. Note: if anyone knows good ways to prevent that sort of behavior at the root, please let me know by commenting on this val! In order to only get notified on a valid subscription, we now subscribe to customer.subscription.updated . This event happens on any subscription change, including renewals and cancellations, so now we have to filter those events to only get new subscriptions, ie where: event.data.previous_attributes.status === 'incomplete' && event.data.object.status === 'active'

View Source Code The CODE box shows you the the full source code of this val, you may need to scroll down to see it. 3. Customize Query Define what you want to search for by modifying query : const query = "\"val.town\" OR \"val.run\" OR \"val town\" -_ValTown_ -is:retweet -from:valenzuelacity -from:val__run"; Refer to Twitter's search operators to fine-tune your query. 4. Test API call Set isProd = false in the code if you are testing, to ensure there are enough tweets to display. Toggle it back to true when you're ready to run this cron job in production and actuall send notifications. 5. Choose Notification Method This template uses a Discord webhook for notifications, but you can update this to your preferred platform by replacing the discordWebhook call with a call to Slack , @std/email , etc. Create a Discord webhook following this guide .

Notifications will be sent using this function: await discordWebhook({ url: Deno.env.get("mentionsDiscord"), content, }); 🎉 Congrats!

Add this to Townie's System prompt by going into Townie's Settings — First ask a user what app they would like you to illustrate. Then create an app outline generator for any app that is requested that produces a simplified, visual representation of the app's interface. Core Functionality - Accept an app name as input (e.g., "Zoom", "Slack", "Discord") - Generate a single val that renders a minimal, branded mockup of the app's main interface - Allow the user to export a png screenshot with transparent background with rounded corners (8px radius) - Move the `html2canvas` import inside the `client()` function. - Wrap the `exportAsPNG` function in a `useEffect` hook to ensure it's only defined on the client-side. - Use dynamic import for `html2canvas` inside the `exportAsPNG` function. - Make sure html2canvas is only loaded and used on the client-side Visual Requirements - Match the app's primary brand colors (limit to 2-3 colors) - Do light or dark mode of the app depending on which is the default for that app - Use placeholder blocks in light gray (#E5E5E5) for text and controls - Include key structural elements specific to the app (e.g., sidebars, headers, content areas), refrain from including text - Use SVG for any icons or logos, built into the component, if needed. - Apply consistent spacing (16px grid) - Ensure the generated outline is compact (around 280x220 pixels) for easy sharing and quick visualization.
