A program to automatically repost messages from a Google Group to a Discord server.

• npm install
• Set up a Gmail account that's subscribed to the Google Group
  • This should work without a Google Group if you just want to repost emails, but I haven't tested that use case
• Get credentials for the Google API
  • See step 1 here for how to do this
• Set up a webhook on the Discord server in question
• Create a secrets.js file, with the following:

process.env.POST_HOOK = '' // Add your webhook URL here
process.env.GOOGLE_CREDENTIALS = JSON.stringify('') // Add Your credentials for the Google API here
process.env.GMAIL_QUERY = ''
// Add the query to repost emails according to. Supports the same query format as the Gmail search box; I recommend 'newer_than:1h list:<name_of_your_group_here>@googlegroups.com'
process.env.NEW_THREAD_ROLE = '' // This line is optional, but if you add the ID of a role, that role will be pinged when the first email of a thread is reposted. You can get the ID of a role by enabling developer mode in Discord, in Settings in the Appearance section, and then right-clicking the role.

• Regarding the Gmail query newer_than:1h list:<name_of_your_group_here>@googlegroups.com -subject:"re:" - that's emails
  • From the mailing list (for obvious reasons),
  • That are newer than one hour (since we'll be setting this up to automatically run every hour),
• npm run repost should give you a URL to visit to authorize the app. Do that, and past in the code it gives you.

-The app will display a token, and ask you to add it as process.env.OAUTH_TOKEN.

Add this to the end of secrets.js: process.env.OAUTH_TOKEN = your token

Now, you should be able to npm run repost and have it work.

I deployed this to Heroku, so that's what the instructions will cover. It shouldn't be hard to adapt to other hosting services, however.

Create a heroku app, and push this to it

From this point on, the process should be very similar to running locally, with the following exceptions:

• Everything that you added to secrets.js before will now be added to the config vars. Also, you'll need to set the config var NODE_ENV to production, if it isn't already.

• You may need to replace http://localhost in the Google credentials with the url of your Heroku app, as well.

• Instead of npm run repost, you'll need to use heroku run npm run repost

• To get it to run automatically every hour, I used Heroku scheduler.

  • Run heroku addons:create scheduler:standard
  • Open the Scheduler dashboard by finding the app in My Apps, clicking “General Info”, then selecting “Scheduler” from the Add-ons drop down
  • Click "Add job" on the scheduler dashboard. The job should be npm run repost, and the frequesncy you pick should match the query - if we're getting emails from the last hour, than we want it to run once per hour.
