Account inquiry engine that exposes GraphQL endpoint for querying data stored in MongoDB
Tech stack:
- Sprint Boot
- Netflx Domain Graph Service framework
- Embedded MongoDB is used to simplify setup and testing
The project is still in POC stage. Contributions welcome!
Checkout the GraphQL Schema. Run the project
by ./mvnw clean spring-boot:run, then use browser to navigate to http://localhost:8080/graphiql to use the GraphQL navigator.
Query example:
{
CasaAccount(accountId: "123") {
accountId
balance
currency
transactions {
edges {
node {
refId
}
}
pageInfo {
hasPreviousPage
hasNextPage
}
}
}
}
Result
