This Node.js script has been written to work on Microsofts Functions-as-a-Service (FaaS) offering, specifically [Azure Functions Timer Trigger](https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-timer). Rewriting it for a vanilla Node.js backend shouldn't require much effort though. Just implement a ```setIntervall()``` method to call the function at specific time intervalls.\n![Intro Pic][screenshot-email]\n\n# Configuration Variables\nTo customize the functionality, you may adjust the following private variables in a ```local.settings.json``` file:\n\n- **\"BTCAddressToMonitor\":** Bitcoin address to monitor, e.g. `bc1q3vdf3np392k28hze3zjffk4mk2ka8z9r593jxn`\n- **\"eMailHost\":** Your email host, e.g. `smtp.office365.com`\n- **\"eMailUserName\":** Your email address, e.g. `john.doe@outlook.com`\n- **\"eMailPassword\":** Email password, e.g. `password123`\n- **\"eMailFrom\":** Text that appears in the from field of the email, e.g. `'John Doe' \u003cjohn.doe@outlook.com\u003e`\n- **\"eMailTo\":** The email address to which the notification mail is sent, e.g. `max.mustermann@gmail.com`\n\nHere is an example of such a ```local.settings.json``` file\n\n```\n{\n  \"IsEncrypted\": false,\n  \"Values\": {\n    \"BTCAddressToMonitor\": \"bc1q3vdf3np392k28hze3zjffk4mk2ka8z9r593jxn\",\n    \"eMailHost\": \"smtp.office365.com\",\n    \"eMailUserName\": \"john.doe@outlook.com\",\n    \"eMailPassword\": \"password123\",\n    \"eMailFrom\": \"'John Doe' \u003cjohn.doe@outlook.com\u003e\",\n    \"eMailTo\": \"max.mustermann@gmail.com\"\n  }\n}\n```\n[screenshot-email]: screenshot.png \"Screenshot of email\"","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frene78%2Faddress-balance-change-notifier","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frene78%2Faddress-balance-change-notifier","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frene78%2Faddress-balance-change-notifier/lists"}
