Develop
Build production-ready backends with Apso. This section is for developers who are past the first quickstart and need to design schemas, customize generated services, connect frontends, test changes, and ship safely.
The Development Model
Apso works best when you treat .apsorc as the contract and generated code as a reproducible implementation of that contract.
- Put entities, fields, relationships, auth, and tenant scope in
.apsorc. - Run
apso generatewhen the contract changes. - Keep custom behavior in extension files.
- Run migration checks before deployment.
- Use the generated REST API and SDK from your frontend.
