„beherbergung“ server
The core of the server is an graphql-api based on specialist.
As database the datalog implementation XTDB is used with a RocksDB data store. Some help how to access the database for development/debug purposes can be found in ./DB.md
Running development server
To start the server and send queries, run:
lein run
curl -H 'Content-type: application/json' -d '{"query":"{ TODO }"}' http://localhost:4000/graphql
Testing
lein test
Production build
lein ring uberjar
java -jar target/beherbergung-*standalone.jar
Reproducible builds
Whenever dependencies are changed, rebuild the mvn2nix-lock.json:
nix run ..#backendUpdatedDeps
This allows to build by:
nix build ..#backend
Configuration
Configuration management is done with yogthos.
Default values are set at src/config.edn, there you see the available options.
In .lein-env.example you find the variables you should set yourself.
To set config options at runtime, use environment variables, java system properties or an .edn file specified using the config environment variable.
Notes to developers
State management
Global state (e.g. instances of database and webserver) are managed by mount.
