This repository is split into multiple parts:
src/api/for the API source codesrc/ui/for the UI source codesrc/common/for common modules between the API and the UI (such as constants, types, errors, etc.)
You will need node>=20 installed, as well as the AWS CLI and the AWS SAM CLI. The best way to work with all of this is to open the environment in a container within your IDE (VS Code should prompt you to do so: use "Clone in Container" for best performance). This container will have all needed software installed.
Then, run make install to install all packages, and make local to start the UI and API servers! The UI will be accessible on http://localhost:5173/ and the API on http://localhost:8080/.
Note: there is currently a known performance issue with running the UI development server in a container. If your requests are timing out, try going to src/ui and running yarn preview to generate a non development server build.
