Oppiabot

Oppiabot is a GitHub app built with probot. It acts as a helper for the Oppia code repository to maintain the development workflow. It is hosted on Heroku.

Getting started

Please refer to the following instructions to setup Oppiabot for the first time on your machine:

1. Create a new folder called opensource/ within your home folder (or use one that you already have). Navigate to it (cd opensource), then fork and clone the Oppiabot repo. This will create a new folder named opensource/oppiabot. Navigate to opensource/oppiabot/.

2. Install Node.Js and NPM on your machine using the following commands:

   First check if you already have Node.js and NPM using:

   node -v
   npm -v

   If these commands show some versions, then you can jump to Point No. 3, else proceed in this point:

   Using Ubuntu

   curl -sL https://deb.nodesource.com/setup_lts.x | sudo -E bash -
   sudo apt install -y nodejs

   Using MacOS

   sudo brew install node

   Using Windows

   Use WSL with Ubuntu and then follow the Ubuntu instructions.

3. Setup probot and other dependencies by running the following command:

  npm install

4. The Oppiabot uses environment variables. These are configured in the server settings. To deploy the bot locally, create a .env file and copy the contents of .env.example to it. You will need to adjust these variables accordingly following the instructions in the subsequent steps. Run following command to copy .env.example to .env

If you have Linux terminal type:

  cp .env.example .env

5. Go to smee.io and click Start a new channel. Set WEBHOOK_PROXY_URL in .env to the URL that you are redirected to.

6. Create a new GitHub App with:

   • GitHub App name: Use something like "My Oppiabot testing App"
   • Homepage URL: Use any random URL
   • Webhook URL: Use your WEBHOOK_PROXY_URL from the previous step.
   • Webhook Secret: development
   • Permissions & events The following permissions and events must be subscribed. If, for example, you only enable issue events, you will not be able to listen on pull request webhooks with the bot.

7. Download the private key. It will be a .pem file. Move it to the root directory of the project. As long as it's in the root directory, it will be automatically detected regardless of the filename.

Make sure you remove

PRIVATE_KEY=example_private_key

from .env file, Otherwise app will not work locally.

8. Edit .env and set APP_ID to the ID of the app you just created and also WEBHOOK_SECRET to development. The App ID can be found in your app settings page here.

Installing the bot on a repository

1. Identify a target repository and install the bot by clicking the Install button on the settings page of your app, e.g., https://github.com/settings/apps/my-oppiabot-testing-app/installations

2. Update the .env file:

   • Add your GitHub account name to WHITELISTED_ACCOUNTS.

3. Add the repository name in the constants.js file:

   • Open the constants.js file in the bot's source code.
   • Navigate to the checksWhitelist object.
   • Add a new entry with your repository name (in lowercase) as the key. The value should define the checks and events specific to your repository.

   Example: If your repository name is my-repo, the checksWhitelist object will look like this:

   const checksWhitelist = {
     // Existing entries...
     'my-repo': {
       [openEvent]: [claCheck],
       [reopenEvent]: [],
       [openEventGithubActions]: [claCheckGithubAction],
       [reopenEventGithubActions]: [claCheckGithubAction],
       [synchronizeEvent]: [mergeConflictCheck],
       [closeEvent]: [allMergeConflictCheck],
       [editEvent]: [],
       [issuesLabelEvent]: [],
       [issuesAssignedEvent]: [],
       [pushEvent]: [],
       [pullRequestReviewEvent]: [pullRequestReviewCheck],
       [issueCommentCreatedEvent]: [respondToReviewCheck],
     },
   };

4. Save the changes to constants.js.

Running the bot locally

You are now ready to run the bot on your local machine. Run npm run dev to start the server. The dev script will start the bot using nodemon, which will watch for any files changes in your local development environment and automatically restart the server.

Other available scripts

npm start to start the bot without watching files.

Debugging

Always run npm install and restart the server if package.json has changed. To turn on verbose logging, start server by running: LOG_LEVEL=trace npm start. Run npm test to run all the tests locally.
