To install Node on the Raspberry Pi Zero, there are two options:\n\n- Install the ARMv6 Node binary for Node11\n- Install an unofficial Node binary from [Node's unofficial releases](https://unofficial-builds.nodejs.org/download/release/) (these aren't all tested before release, so it could break; they're considered experimental)\n\nI'm using [Node v11.15.0](https://nodejs.org/fa/blog/release/v11.15.0/) on my Raspberry Pi Zero to run the application.\n\nIf you decide to use a newer version of Node, you might need to change how the file imports/exports are configured. There have been changes to how these work between older and newer versions of Node.\n\n### Environment Variables\n\nThis application uses [`dotenv` to handle environment variables](https://rebeccamdeprey.com/blog/securely-manage-environment-variables-for-js-apps-with-dotenv). There's a dev.envrc file in the repo. This stores placeholder values for environment variables needed by the application.\n\nUse the command below to make a copy of the `dev.env` file called `.env`.\n\n```\ncp dev.env .env\n```\n\nAfter copying the dev.env file, update the variable values in the new `.env` file with the appropriate values for your setup.\n\n**Variable Definitions**\n\n| Name                  | Expected Value                                                                                                                                                                                                          |\n| --------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| `TENANT_ID`           | The tenant (aka directory) ID from your app registration in the Azure Portal                                                                                                                                            |\n| `CLIENT_ID`           | The client (aka application) ID from your app registration in the Azure Portal                                                                                                                                          |\n| `CLIENT_SECRET`       | The value of the client secret you created for your app in the Azure Portal                                                                                                                                             |\n| `AAD_ENDPOINT`        | Appended to the tenant ID for use as the authority URL for getting tokens. You can likely use the default.                                                                                                              |\n| `GRAPH_ENDPOINT`      | Used to get the scopes when getting tokens. You can use the default.                                                                                                                                                    |\n| `OUTLOOK_CALENDAR_ID` | The ID for the calendar that you want to get events from. You can get this from the [Microsoft Graph Explorer](https://developer.microsoft.com/en-us/graph/graph-explorer) by running the \"Get all my calendars\" query. |\n| `PUSHOVER_TOKEN`      | API token for Pushover service to send errors as push notifications to your phone (optional)                                                                                                                            |\n| `PUSHOVER_USER`       | User ID for Pushover service to send errors as push notifications to your phone (optional)                                                                                                                              |\n\n**DO NOT check the `.env` file into a public code repository.** It contains keys for your application in plain-text and someone else could use them to access your data.\n\n## Error Notifications\n\nThe application is configured to send push notifications via the [Pushover service](https://pushover.net/). If you want to use this, make sure\nto add your user ID and API token in your `.env` file. Otherwise, remove the request to Pushover from the `catch` block in the `index.js` file.\n\n## Running the Console Application\n\nTo run the console application, do the following:\n\n1. Navigate to the application folder on the Raspberry Pi's command line\n2. Run `npm install` to install dependencies\n3. Run `npm start` or `node index.js` in the application folder to start the console app\n\nYou can use `pm2` to [automatically start the application on your Raspberry Pi](https://rebeccamdeprey.com/blog/automatically-start-nodejs-applications-when-your-raspberry-pi-boots-up) whenever you restart it.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frdeprey%2Fmeeting-indicator","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frdeprey%2Fmeeting-indicator","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frdeprey%2Fmeeting-indicator/lists"}
