# pkg/server/api/console/v1
|
||||
|
||||
GraphQL API using `gqlgen`. Schema-first approach.
|
||||
|
||||
## Generated vs hand-written
|
||||
|
||||
| File | Type | Notes |
|
||||
|------|------|-------|
|
||||
| `graphql/*.graphql` | Hand-written | GraphQL schema split by entity (one file per coredata model) |
|
||||
| `gqlgen.yaml` | Hand-written | Codegen config |
|
||||
| `resolver.go` | Hand-written | Root `Resolver` struct and `NewMux` |
|
||||
| `graphql_handler.go` | Hand-written | Handler setup |
|
||||
| `*_resolvers.go` | Generated stubs | Per-entity resolver files (edit the bodies) |
|
||||
| `schema/schema.go` | **Generated — DO NOT EDIT** | Executable schema |
|
||||
| `types/types.go` | **Generated — DO NOT EDIT** | Type definitions |
|
||||
|
||||
## Schema file organization
|
||||
|
||||
Schema files live in `graphql/` and are split by coredata model:
|
||||
- `base.graphql` — directives, scalars, Node, PageInfo, root Query/Mutation/Organization/Viewer types
|
||||
- Entity files (e.g., `vendor.graphql`, `control.graphql`) — use `extend type Organization`, `extend type Mutation`, etc. to add fields
|
||||
|
||||
When adding a new entity, create a new `.graphql` file in `graphql/`. Types that get extended across files (Organization, Mutation, Viewer) must be defined in `base.graphql`.
|
||||
|
||||
## Important rules
|
||||
|
||||
- **Never edit generated files** (`schema/schema.go`, `types/types.go`). Only edit `graphql/*.graphql` and resolver bodies.
|
||||
- **After any change to `graphql/*.graphql`**, always run codegen:
|
||||
|
||||
```
|
||||
go generate ./pkg/server/api/console/v1
|
||||
```
|
||||
|
||||
## Resolver pattern
|
||||
|
||||
Every resolver method follows this sequence:
|
||||
|
||||
1. **Authorize** — `r.authorize(ctx, obj.ID, probo.ActionXxxGet)`
|
||||
2. **Get service** — `prb := r.ProboService(ctx, tenantID)`
|
||||
3. **Call service** — `result, err := prb.Foo.Bar(ctx, ...)`
|
||||
4. **Handle error** — wrap or panic on unexpected errors
|
||||
|
||||
## Pagination
|
||||
|
||||
Relay cursor pattern:
|
||||
- `page.Cursor[OrderField]` for cursor handling
|
||||
- Connection types (`*Connection`) with `ParentID`, `Resolver`, `Filter` fields
|
||||
|
||||
## Custom scalars
|
||||
|
||||
`ID`, `Datetime`, `CursorKey`, `Duration`, `BigInt`, `EmailAddr` — mapped in `gqlgen.yaml`.
|
||||
|
||||
## Authentication middleware
|
||||
|
||||
`NewMux()` chains: session → API key → identity presence middlewares.
