Add an email entry option to your static website/blog. Easy peasy. 🚀 PoV: You just hacked together a portfolio website or launched a blog as a static website. Some people who visit might be interested in hearing more from you. ❤️ But you don't want to get lost building your backend, API, DB or fancy apps like SubstandardStack or MailMachineGun for people to sign up to your newsletter. 😩 All you want is a simple input box on your website - when someone types their email , username or social link in and submits it, you want to be notified. psst...do you want another one that uses the DB instead of email so you can look up all entries at once? Let me know and I'll get cooking! Quickstart Call the val URL with data in the query param userContact . That's it! // Format `https://<val_url>?userContact=<mandatory_primary_contact>` // Examples `https://dvsj-subscribeToNewsletter.web.val.run?userContact=dav.is@zohomail.in` `https://dvsj-subscribeToNewsletter.web.val.run?userContact=CatalanCabbage` Bonus Have extra data apart from email? Pass any encoded data in the queryParam userData , will be included in the email. It's optional. // Format `https://<val_url>?userContact=<mandatory_primary_contact>&userData=<optional_any_data>` //Examples `https://dvsj-subscribeToNewsletter.web.val.run?userContact=dav.is@zohomail.in&userData={"time": "2/2/1969", "twitter": "https://twitter.com/dvsj_in"}` // Note: All values should be URL encoded. Example: let userData = {"time": "2/2/1969", "twitter": "https://twitter.com/dvsj_in"} let encodedUserData = encodeURIComponent(userData) //This should go in the query param Want bot protection? Add a simple question to your website, like "okay, so what's one minus one?" . In the val, set isBotProtectionOn = true and botProtectionAnswer="0" . When you call the val, include the encoded user's answer to the bot question as botProtection query param. Answer will be compared with botProtectionAnswer ; if the answer is wrong, the request is rejected. // Format `https://<val_url>?userContact=<mandatory_primary_contact>&userData=<optional_any_data>&botProtection=<answer>` //Examples `https://dvsj-subscribeToNewsletter.web.val.run?userContact=dav.is@zohomail.in&botProtection=123` Add it to your website Want to add it to your site but get a headstart coding it? Use this ChatGPT prompt to get code for your website! I'm building a simple form submission component. It should a submit button and these 2 input boxes: 1. "userContact" to get the user's email (mandatory) 2. "userData" to get a custom message from the user (optional) On clicking the submit button: 1. Both input values should be encoded using "encodeURIComponent" 2. A GET URL should be built in this format with query params. Include userData query param only if input is not null or empty. `https://dvsj-subscribeToNewsletter.web.val.run?userContact=<encodedUserContact>&userData=<encodedUserData>` 3. The GET URL should be called and result printed in the console. I'm using React, so make it a react component.

Pass a URL to ping a website and see if response is a 200. If it isn't, you get an email with the error response received. Tip: Make a new, separate cron val to call this isMyWebsiteDown() periodically to check the website's health every 15 minutes or so. Your separate cron val's code will look something like this: //Import this val import isMyWebsiteDown from "https://esm.town/v/dvsj/isMyWebsiteDown"; //Add all the websites you want to check isMyWebsiteDown(`https://dvsj.in`); isMyWebsiteDown(`https://blog.dvsj.in`); export default {};

You know how when you paste a URL in Twitter or Slack it shows you a nice preview? This val gives you that data. Given a URL, this will return metadata about the website like title , description , imageURL , image as base64 etc. Sample input - paste this in your URL bar https://dvsj-GetWebsiteMetadata.web.val.run?targetURL=https://dvsj.in https://dvsj-GetWebsiteMetadata.web.val.run?targetURL=<your-target-url-here> Sample output: { status: 200, url: "https://dvsj.in", title: "Dav-is-here ➜", description: "Davis' not-so-secret stash", imgUrl: "https://www.dvsj.in/cover-picture.png", imgData: "data:image/png;base64,qwertyblahblah" } FAQ: Why is imgData sent when imgUrl is already present? Because you shouldn't hotlink images from 3rd parties. Store the base64 image on your server and use it in your app. It's unfair to use their server bandwidth and could be a security issue for you if they change the content of the link later.
