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.

californiaBusinessNotifications

California business records change notifications There's nothing I like more than a little open data and transparency! This Val shows you how to use the California Secretary of State Business Search as a faux-API and get notifications when records change. This lets you know when a business updates their records, changes their good-standing status, and so on. Here's how to use it: Fork this val Open the California Secretary of State Search . Open your browser's inspector tools. Search for the business you're interested in, and click on its header row. Now, in the network tab of your developer tools, you should see a request that ends with false . You'll find a number in that URL. Plug that number into the val at the spot at the top. (We're almost there!) Now just run the val and you should get a notification! If you want to get these intermittently, schedule the val. It's probably not necessary to run this more than once a week - businesses update these details very infrequently. Notes opencorporates has a way better system for open data around businesses, but to get a free API key you need to be a nonprofit or a registered journalist, and I am neither. But if you are, use that! Thanks to America's laws around business registration, it's commonplace for businesses to mask their control and ownership by using registration agents and a few layers of corporate structure.
