google-calendar-generator

google-calendar-helper

This is just a side project I did for adding events to my personal Google Calendar using the Google API. I was tired of adding multiple events all with the same configuration and having to go back and update all of them when manually I wanted to make changes.

Disclaimer: The library isn't necessarily comprehensive in covering all of Google Calendar's available APIs, does not have test cases, and may not be generic in all scenarios; this was primarily made for my own use cases.

Usage

1. Follow only Step 1 of Google's Node.js Quickstart. This will result in a credentials.json file.
2. Run the following command anywhere in your terminal

npx google-calendar-generator --credentials ./PATH/TO/credentials.json --token ./PATH/TO/token.json --config ./PATH/TO/config.js

NOTE: The first time you run the program, you will not have a token.json. For the --token, just specify where you would like the token.json to be auto-generated.

1. Check out your new calendar at https://calendar.google.com/

See ex-calendar-config.js for an example calendar configuration
