Hermod

The Hermod project is currently a monorepo split into two projects - api and www.

Api contains a Rust server application executable that serves as our project's backend.

Www contains a React webserver that serves as our project's frontend.

Spec.yaml contains Digital Ocean Application specifications for our project's deployment.

To view the project's auto-generated documentation, run cargo doc --open locally, or view the latest version online.

Useful commands

# Install optional Rust command-line utilities
cargo install sqlx-cli # (Optionally) Install sqlx CLI
cargo install bunyan # (Optionally) install Bunyan log formatter

# Other useful commands
cargo doc --open # Compiles and opens project documentation (aka cargo d)
cargo test # Runs unit and integration tests (aka cargo t)

cargo r | bunyan # Compiles and runs the project, piping log output to the Bunyan formatter
TEST_LOG=true cargo t | bunyan # Runs tests with logging, piping output to Bunyan

./scripts/stop_db.sh # Stops the PostgresDB Docker container

sqlx mig add YOUR_MIGRATION_NAME # Create a new sqlx migration
sqlx mig run # Run your new migration
cargo sqlx prepare -- --bin hermod # Rebuild sqlx's cache used for compile-time SQL guarantees

docker build -t hermod_api . # Build the release image of the application (will take a *very* long time, Rust has infamously long release compilation times)
docker run -p 8000:8000 hermod_api # Run the release image of the application

Project Architecture

• configurations contains three files - base.yaml, local.yaml, and production.yaml. Base.yaml contains default configuration shared between local and production, and local and production specify configuration settings that differ between the two environments.
• migrations
• scripts
• src
• tests
• .env
• Cargo.toml
• Dockerfile
• sqlx-data.json
