Missive GCal Export Integration

Adds an integration to the Missive mail app that parses emails for dates/times and displays them to export to Google Calendar if desired. Clicking the export button will automatically open Google Calendar's "New Event" page and allow you to customize fields' content.

Deploying

Three files (index.html, main.js, theme.css) need to be deployed to a server that the Missive app can reach. Any of the following options will work:

Instantly clone/fork and deploy this repo from your Github
A sample is deployed on my netlify account
Run the integration from source on a local server by executing yarn start after changing the text following the tunnel command on line 21 of package.json from --subdomain missive-gcal to --subdomain [YOUR TEXT]. The local server sometimes fails to start due to a bug with localtunnel, just run yarn start again.

Activating the Integration

open the Missive desktop app
click on your profile at the bottom left
click Integrations in the flyover menu
click Add integration at the bottom of the modal
select the Custom option with a gear at the bottom of the list
enter Name & iFrame URL as...
- Name: Google Calendar Export
- iFrame URL: https://[YOUR TEXT].localtunnel.me or https://gcal.netlify.com or url of your server or Netlify URL that's hosting the previously mentioned 3 files
Close modal

Known Issues

rudimentary timezone indicator fix requires manually removing and causes issues when not located in the timezone from the email (i.e. does not localize)
most Eastern timezones result in datetime detection failure
fails detection if "the 10th" isn't preceded by a day this week (needs custom chrono.js parser feature)
temp replacement since localhost.me ent down, investigate tunnel-tool and DIY ngrok
