Goal

probot-serverless-now is a wrapper around Probot to run your GitHub Apps as Serverless Functions with ZEIT Now.

Note: This package is not maintained anymore as GitHub Actions and github-app-token can, most of the time, replace Probot.

Usage

• app.js

  module.exports = app => {
    app.on("issues.opened", async context => {
      // A new issue was opened, what should we do with it?
      context.log(context.payload);
    });
  };
  

• api/index.js

  const { toLambda } = require("probot-serverless-now");
  
  const applicationFunction = require("../app");
  
  module.exports = toLambda(applicationFunction);
  

• now.json

  {
    "version": 2,
    "env": {
      "APP_ID": "@my-app-id",
      "PRIVATE_KEY": "@my-app-base64-encoded-private-key",
      "WEBHOOK_SECRET": "@my-app-webhook-secret"
    }
  }
  

Supported Probot Features

• [x] Logging
• [x] Sentry integration
• [x] Webhook signature verification
• [ ] Loading the private key from the filesystem. The PRIVATE_KEY environment variable should be used instead (possibly base64 encoded).
• [ ] Custom routing. The only routes are:
  • GET /: typical Probot landing page
  • POST /: webhook handler
• [ ] Multiple applications running under the same Probot instance. Instead, you should create multiple Now Lambdas. Each lambda should have its own now.json file since they won't share the same APP_ID, PRIVATE_KEY, and WEBHOOK_SECRET environment variables. To do that, you could either use multiple repositories or a mono-repo with Yarn workspaces or Lerna for instance.
