InjectCodeOnValTownStream

Injects the "Code on Val Town" ribbon on an HTML string stream

• new InjectCodeOnValTownStream({ handle: "andre", name: "foo" }) - define which val to link to;
• new InjectCodeOnValTownStream() - infer the val from the call stack.

Example: @andreterron/openable_stream

Create val
import { InjectCodeOnValTownStream } from "https://esm.town/v/andreterron/InjectCodeOnValTownStream";
import { blob } from "https://esm.town/v/std/blob?v=11";
import { html } from "https://esm.town/v/stevekrouse/html?v=5";

export default async (req: Request): Promise<Response> => {
  await blob.set(
    "openable_test",
    `<h2>Hello world!</h2>
    <style>* { font-family: sans-serif }</style>`,
  );

  const value = await blob.get("openable_test");

  return html(
    value.body
      .pipeThrough(new TextDecoderStream())
      .pipeThrough(new InjectCodeOnValTownStream())
      .pipeThrough(new TextEncoderStream()),
  );
};
