SF Life Line (https://www.sanfranciscolifeline.com/) creates and distributes free communication tools to help bridge language barriers between patients and first responders in emergency medicine. This collaboration with SF Civic Tech (https://www.sfcivictech.org/) is building a complementary technology to augment those tools with a web-based app that can be accessed on any smartphone, tablet, or computer.

1. Install Docker Desktop.

2. Clone the repo to a directory on your computer.

3. Create a .env file in the /server directory with the values from the .env.example file.

4. In a command-line shell, navigate to the repo directory. Inside the root directory of this project, run docker compose up. It may take a few minutes to download and/or build the necessary images to run the codebase.

5. To run commands related to the codebase, you should first "log in" to the running server to execute them in the container so that you have access to installed dependencies. To do so, leave the server running in one shell, open another in the same repo directory, then run docker compose exec server bash -l. You can then execute commands like npm install, etc.

   Note that the configuration does not share dependencies like node_modules between your host OS file system and the container to prevent mismatches (i.e. dependencies with native binaries that won't be the same inside the Linux-based container vs a Windows/Mac host).

6. If you're using VSCode as an editor, you can improve auto-completion and syntax highlighting by using the Dev Containers extension to connect to the running container so it has access to installed dependencies. Once you attach to the running container, you can open the "remote folder" /opt/node/app which is where the code is located inside the container.

7. To stop the application, you can press CONTROL-C inside the shell where you ran docker compose up.

   If you've "logged in" to the server container using docker compose exec server bash -l, press CONTROL-D or type exit or logout to exit the container back to your host OS shell.

   If the application does not terminate gracefully after CONTROL-C (use docker ps to see running processes), run docker compose stop to terminate any running processes.

• On macOS, if you're unable to start the server listening on port 5000, go to System Preferences, search for Airplay Receiver, and turn it off to release the port.
