Just a small node app running a cron to trigger SMS and email event reminders for birthdays, MOTs etc.

• Email (Nodemailer)
• SMS (Twilio)
• WhatsApp (Twilio Beta)

• Local .json file
• Google Calendar API

This was created largely for my use case so hasn't been developed as a configurable package, however I think it should be fairly easy to adapt to your own purposes due to its modular build and easily swapped out account variables.

• The app runs a cron to trigger the reminder functionality at specific times, using the node-cron package.
• The cron schedule is easily configurable via the crons.js file.
• Each successful cron event is logged to a txt file.
• If running the Node app on a Linux server then the timezone needs to be set to match the cron schedule. You can use dpkg-reconfigure tzdata on Ubuntu. date to check.

• The Google Calendar integration requires a Service Account signed up to the Calendar API via the Google Developer Console.
• The Service Account needs to have access to your private calendar - share your calendar with the Service Account via the calendar itself.
• A 'credentials.json' file is required to authenticate with the Google Auth library used. You can find an example of what this should look like here. You could also use ENV variables for this. Obviously remember to gitignore!
• The Google documentation around auth isn't great, particularly when trying to authenticate server to server :/
• Currently set up to only pull events from the calendar that include the string 'notifyme' somewhere. This can be easily changed!

• As well as pulling from Google Calendar, the app can also pull from a local .json file. An example of the structure it requires is provided in data-example.json.
• When the app is running, any changes to the a file within the data folder will trigger a backup to be taken in a separate folder to prevent accidental loss of data. 30 backups are kept.
• The various log files need to be created in the logs folder when you set up the app or the process will fail.

• You'll need an account with Twilio, but if usage is low then the trial tier is fine.
• ENV variables for the Twilio SID and Auth Token are needed plus private variables for your phone number and the Twilio sender numbers. Twilio have some pretty good guides available.
• A log file is used to log the status of message requests.

• Nodemailer needs to have an SMTP transporter object created. This could be something like Mailgun, SendGrid etc. but I am using Gmail. For higher usage you would need a dedicated SMTP solution.

• These are required for the 3rd party integrations and also to determine which combination of data source and services are used.
• Please see .env.example for a list of the fields used.

• Add a basic auth-locked settings page to allow add/edit/delete of events. Nuxt?
