Use this script send invites in bulk to join a team (new or existing) under an organization on GitHub.
Checkout this repo and make sure you're using Node v10 or more recent.
You can supply default values in an .env file (gitignored for security reasons):
GH_PAT=YOUR_PAT_GOES_HERE
GH_USER=octocat
GH_ORG=github
You will need to be an owner of the organization and the PAT will need read/write access to the Org permission scope. To run the first time:
npm install # do this only once
node cli.js
Follow the interactive prompt to supply the team you want to invite members to, and the comma-separated list of email addresses (or existing usernames) you want to invite.
