Google sheets to ical feed

This app will read event records out of Google sheets and create an ical feed.

Setup

1. Clone this project! Duh! You'll want your own copy of this code.

2. Set up a Service Account for Google sheet.

   You can find more information at https://developers.google.com/android/management/service-account

   Go to https://console.developers.google.com/projectselector2/apis/credentials and create/select a project.

   Click Create Credentials and select Service Account. Give your Service Account a name, ID and description. Next, click Create Key, select JSON, and downlaod your credentials.

   Share your Google sheet with your Service Account ID. Your Service Account ID will be in the form your-service-account@your-project.iam.gserviceaccount.com

3. Copy the config.yaml.example to config.yaml.

   Set authJSONFile to the Service Account credentials JSON file you downloaded in the previous step.

   Set the spreadsheetID to your Google sheet ID and the sheetName to the sheet name.

   Set the startRow. If you have a header row, set this to 2 (or higher if you have multiple header rows). Otherwise, set this to 1.

   Set your columns. Each column definition should include a column (letter), name (arbitrary text), and (if required) a required attribute.

   Set the endpoint. Once you deploy the app, your ical feed will be available at your-domain/cal/<endpoint>.

   Set the ical fields. You must include the dtstart, dtend, and summary fields. Values may include placeholders (enclosed in square brackets) for the columns you previously defined.

4. Commit your configs.

5. Add your Heroku remote: heroku git:remote -a your-heroku-app.

6. Create an environment variable named CREDS_JSON with the contents of your JSON credentials file.

7. Deploy!
