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)

Create val
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

Create val
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:

Create val
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.
