Write you own GitHub webhooks with Deno Deploy. Deno Deploy is where you can distribute your JavaScript/TypeScript code to the edge with one line of command.

Quick start

Setup your Deno Deploy account and create a new project then write your webhook logic in TypeScript with full typing support.

// main.ts
import {
  app,
  makeLarkSender,
  pullRequest,
  pullRequestReview,
} from "https://deno.land/x/ghook/mod.ts";

const send = makeLarkSender(YOUR_LARK_ENDPOINT);

app("/webhook", { secret: "test" })
  .on("pull_request", (e) => send(pullRequest(e)))
  .on("pull_request_review", (e) => send(pullRequestReview(e)));

Now copy the code into Deno Deploy’s playground or deploy it with deployctl:

deployctl deploy --project=YOUR_PROJECT_NAME --prod ./main.ts

Copy the URL of the webhook and paste it in the GitHub repo’s webhook settings, the pathname in the example code is /webhook, so the url will be https://YOUR_PROJECT_NAME.deno.dev/webhook.

You can also create multiple endpoints for different repos so you can reuse some code. Just call app multiple times:

app("/webhook1");
app("/webhook2");
app("/webhook3");

It also provided some function to generate markdown texts in reponse to certain GitHub events including pullRequest, pullRequestReview, etc.
