# smithplates-plugin

Scala/SBT Smithy build plugin that extracts SQL and HTTP IR from a Smithy model, plans codegen via language-neutral `outputs.json` decks, renders dialect-specific SQL DDL, runs SQL database service codegen, and runs HTTP server/client codegen. SQL codegen combines service IR, SQL IR, and Scalate SSP templates into target-language repository artifacts and integration tests. HTTP codegen produces FastAPI servers (Python), HTTP clients (Python HTTPX/HTTPX2 and TypeScript axios/fetch), WebSocket endpoints, shared models, and problem detail helpers. See the [codegen pipeline](../../docs/contributing/architecture.md) for the full architecture.

## Traits

Smithy trait IDL is packaged into the published plugin dependency graph from [`../smithplates-sql-ir/`](../smithplates-sql-ir/) (`META-INF/smithy/smithplates.codegen.sql.smithy`), [`../smithplates-sql-service-ir/`](../smithplates-sql-service-ir/) (`META-INF/smithy/smithplates.codegen.sql.service.smithy`), and [`../smithplates-http-ir/`](../smithplates-http-ir/) (`META-INF/smithy/smithplates.codegen.http.smithy`). Each trait jar also includes `META-INF/smithy/manifest` so Smithy CLI model discovery loads those resources from Maven dependencies. User overviews: [`docs/usage/sql-plugin.md`](../../docs/usage/sql-plugin.md) and [`docs/usage/http-plugin.md`](../../docs/usage/http-plugin.md).

### SQL traits

| Trait | Target | Maps to |
|-------|--------|---------|
| `@sqlTable(name: String)` | `structure` | `SqlTable` |
| `@sqlColumn(name: String?)` | `member` | `SqlColumn.name` override |
| `@sqlColumnIndex(index: Integer)` | `member` | Stable `@sqlTable` member ordering for DDL, queries, and codegen; unindexed members keep Smithy definition order; timestamp traits default to second-to-last / last |
| `@sqlVarchar(maxLength: Integer)` | `:test(string, member > string)` | `SqlColumnType.Varchar` on the member or on a string type alias |
| `@sqlUuid` | `:test(string, member > string)` | `SqlColumnType.Uuid` on the member or on a string type alias; never inferred from shape names |
| `@sqlJson` | `member` | `SqlColumnType.Json` for list, map, structure, or union members (explicit only; not inferred) |
| `@sqlPrimaryKey` | `member` | primary key column |
| `@sqlIndex(name: String?)` | `member` | `SqlIndex` |
| `@sqlUniqueIndex(name: String?)` | `member` | unique `SqlIndex`; on `@sqlForeignKey` members models a one-to-one relationship |
| `@sqlForeignKey(references: String, column: String?)` | `member` | `SqlForeignKey` with `ManyToOne` cardinality by default |
| `DerivedStruct` | `structure` | Sentinel empty shape for derive inputs and `@sqlDeriveSelect` output; codegen expands members |
| `@sqlDeriveInsert(targetTable: String)` | `operation` | INSERT derived from table members; input must be `DerivedStruct`; output is PK type or a RETURNING structure |
| `@sqlDeriveUpdate(targetTable: String)` | `operation` | UPDATE derived from table; input `DerivedStruct`; output `Boolean`; WHERE uses PKs, SET uses updatable columns |
| `@sqlDeriveDelete(targetTable: String)` | `operation` | DELETE derived from table; input `DerivedStruct`; output `Boolean`; WHERE uses PKs; SQL uses RETURNING on PK columns |
| `@sqlDeriveSelectOne(targetTable: String, joins: sqlSelectJoinList)` | `operation` | SELECT by PK; input `DerivedStruct`; output is the target `@sqlTable` when `joins` is empty, otherwise `DerivedStruct` with nested joined structures (singular for many-to-one/one-to-one, list for one-to-many). Singular nested members follow FK member requiredness (`@required` → required, otherwise optional). Join ON clauses resolve from the nearest prior joined table when no direct FK exists on the target table. |
| `@sqlDeriveSelect(…)` | `operation` | SELECT derived from trait lists; `projections` defaults to `"*"` (all columns from `from`/joins as `{alias}_{member}` fields) or an explicit list; input is an explicit structure; output must be `DerivedStruct` |
| `@sqlUpdate(tableRef: String)` | `structure` | UPDATE query for the referenced `@sqlTable` |
| `@sqlService` | `service` | SQL data-access service with flat `operations` only (no `resources`; see below) |
| `@sqlAutoUuid` | `member` | Database-generated UUID (implies `@sqlUuid`); omit from inserts; include PK on updates |
| `@sqlAutoIncrement` | `member` (`Integer`) | Database-generated serial PK — SQLite `INTEGER PRIMARY KEY AUTOINCREMENT`, Postgres `GENERATED ALWAYS AS IDENTITY`; omit from inserts; include PK on updates |
| `@sqlCreatedTimestamp` | `member` | Set on insert; omit from insert/update inputs |
| `@sqlUpdatedTimestamp` | `member` | Set on insert/update; omit from insert/update inputs |

### HTTP traits

| Trait | Target | Maps to |
|-------|--------|---------|
| `@httpService(serialization: HttpSerializationFormat = "json")` | `service` | HTTP API service selected for Smithplates HTTP codegen |
| `@httpCookieAuth(name: String)` | `service` | Smithy authentication definition for a named HTTP cookie; supported by FastAPI, HTTPX/HTTPX2, and fetch REST generation |
| `@httpStaticHeader(name: String, value: String)` | `structure` | Fixed response header binding for generated HTTP output handling |
| `@httpProblem(type: String = "about:blank", title: String, detail: String?, code: Integer?)` | `structure[trait|error]` | RFC 9457 problem detail exception and response handling; `code` implies `@httpError` |
| `@websocket` | `operation` | Bidirectional WebSocket endpoint (requires `@http` URI + `@tags`); dedicated server/client templates |

Smithy `@nestedProperties` on a single `@httpPayload` input member flattens the payload target as the HTTP body (see [HTTP plugin — Nested payload bodies](../../docs/usage/http-plugin.md#nested-payload-bodies)).

`Document` and `Blob` members map to JSON and binary columns respectively. Smithy `enum` shapes map to `SqlColumnType.StringEnum` (Postgres `CREATE TYPE … AS ENUM`, SQLite `TEXT` with `CHECK`); `intEnum` maps to `SqlColumnType.IntEnum` (integer column with `CHECK` on allowed values). Lists, maps, and nested structures require `@sqlJson` on the member to store as JSON.

Auto-generated columns receive dialect-specific `DEFAULT` clauses in DDL. Build-time migration files contain schema DDL only; derived INSERT, UPDATE, DELETE, and SELECT statements are rendered for SQL service implementations using dialect placeholders (`%s` for generated Postgres Python, `?` for SQLite). `@sqlDeriveInsert`, `@sqlDeriveUpdate`, `@sqlDeriveDelete`, and `@sqlDeriveSelectOne` use `input: DerivedStruct`. `@sqlDeriveSelect` uses an explicit input structure for bind parameters and `output: DerivedStruct` for projection-derived result fields. `projections` defaults to `"*"`, expanding every column from `from` and joined tables as explicit `{alias}_{member}` result fields; use an explicit projection list for aggregates, `groupBy`, `having`, or `orderBy`. Use `from: { table: ShapeId, alias: String? }` for the primary table; joins accept `tableAlias`. Reference bind parameters as `input.memberName` and table columns as `alias.columnName` (or bare column names when unique). Filter conditions use `{ left, operator, right }`; WHERE may reference table columns only; HAVING may reference projections (including aggregates).

```smithy
@sqlTable(name: "foos")
structure Foo {
    @sqlPrimaryKey
    @sqlAutoUuid
    id: String
    @sqlForeignKey(references: "example#Bar")
    bar_id: String
    @sqlVarchar(maxLength: 128)
    name: String
    @sqlIndex(name: "idx_foos_created_at")
    @sqlCreatedTimestamp
    created_at: Timestamp
    @sqlUpdatedTimestamp
    updated_at: Timestamp
}

use smithplates.codegen.sql#DerivedStruct

@sqlDeriveInsert(targetTable: "example#Foo")
operation CreateFoo {
    input: DerivedStruct
    output: CreateFooOutput
}

structure CreateFooOutput {

}

}

operation GetFoo {
    input: DerivedStruct
    output: Foo
}

    bar_id: String
    minCount: Integer
}

@sqlDeriveSelect(
    from: { table: "example#Foo", alias: "f" },
    joins: [{ table: "example#Bar", type: "inner", tableAlias: "b" }],
    projections: [
        { alias: "fooId", source: "f.id" },
        { alias: "barName", source: "b.name" },
        { alias: "fooCount", aggregate: "count", source: "f.id" }
    ],
    where: [{ left: "f.bar_id", operator: "=", right: "input.bar_id" }],
    groupBy: ["f.id", "b.name"],
    having: [{ left: "fooCount", operator: "=", right: "input.minCount" }],
    orderBy: [{ projection: "fooId", direction: "asc" }]
)
operation ListFoos {
    input: ListFoosInput
    output: DerivedStruct
}

@sqlUpdate(tableRef: "example#Foo")
structure FooUpdate {
    @required
    id: String
    @required
    name: String
}

@sqlService
service FooRepository {
    version: "1"
    operations: [FindFoo]
}

structure FindFooInput {
    @required
    id: String
}

structure FindFooOutput {
    @required
    name: String
}

@error("client")
structure FooNotFound {
    @required
    message: String
}

operation FindFoo {
    input: FindFooInput
    output: FindFooOutput
    errors: [FooNotFound]
}
```

`@sqlService` operations model repository methods (`input` → `output | errors`). The `smithplates` plugin renders Scalate SSP templates into interface and model artifacts from each `@sqlService` when a language `sql` block is configured. Annotate operations with `@sqlDeriveInsert`, `@sqlDeriveUpdate`, `@sqlDeriveDelete`, `@sqlDeriveSelectOne`, or `@sqlDeriveSelect` to derive SQL from the target table.

`@sqlService` services use flat `operations` lists, not Smithy `resources`. The natural mapping would be one table per resource, but resource `properties` cannot carry SQL traits on members (`@sqlPrimaryKey`, `@sqlForeignKey`, `@sqlColumn`, …). Tables stay as annotated `@sqlTable` structures; duplicating that metadata elsewhere for resources would hurt authoring UX without much gain.

## Build and test

```bash
sbtn test publishM2
```

Tests load the same packaged traits via `SqlTestModelLoader` from the compile classpath. Build inline models with [`SqlTestModelBuilder.assemble`](../smithplates-sql-ir/src/test/scala/com/jacoby6000/smithplates/sql/SqlTestModelBuilder.scala) (`smithplates-sql-ir` tests); do not duplicate trait definitions.

Dialect renderer tests live under `sqlite` and `postgres` test packages (`SqliteRendererSpec`, `PostgresRendererSpec`).

Docker-backed schema-path integration tests (SQL IR → dialect DDL → real databases) live in [`../smithplates-sql-ddl-renderer-postgres-it/`](../smithplates-sql-ddl-renderer-postgres-it/) and [`../smithplates-sql-ddl-renderer-sqlite-it/`](../smithplates-sql-ddl-renderer-sqlite-it/).

## Schema DDL export

The **schema and migrations** path renders SQL IR to dialect-specific DDL and writes versioned migration files under `migrationLocation` (initial `v1_initial_schema.sql` for a fresh project). [`SmithplatesBuildPlugin`](src/main/scala/com/jacoby6000/smithplates/plugin/SmithplatesBuildPlugin.scala) calls [`DialectRenderers.renderDdlOnly`](src/main/scala/com/jacoby6000/smithplates/plugin/DialectRenderers.scala). Per-language migration runners are generated via SQL database service codegen templates (Python today).

## SQL database service codegen

**SQL database service codegen** (database services and operations IR + SQL IR + Scalate SSP templates → query models, interfaces, dialect-specific implementations, and tests) is configured under `smithplates.<language>.sql` (see [`docs/usage/configuration.md`](../../docs/usage/configuration.md) and [`docs/usage/integration.md`](../../docs/usage/integration.md)). [`SqlServiceCodegenRenderer`](../smithplates-sql-service-renderer/src/main/scala/com/jacoby6000/smithplates/sql/service/renderer/SqlServiceCodegenRenderer.scala) (in `smithplates-sql-service-renderer`) expands the language's `outputs.json` deck with `CodegenPlanner` and renders SSP templates with [Scalate](https://github.com/scalate/scalate) for each `@sqlService` in the model. Bundled Python templates live under [`../../templates/python/src/db/`](../../templates/python/src/db/) and are packaged as compile resources (default `classpath:`); bundled artifacts are selected from enabled dialects via deck `variants`.

Template and output layout for the bundled `db` service type (paths relative to `sourceOutputDir` / `testOutputDir`; namespace-aware):

```
db/
  outputs.json
  models/models.ssp
    → {{smithyNamespaceDir}}/models/{{serviceModuleName}}_models.py
  service_protocol.ssp
    → {{smithyNamespaceDir}}/{{serviceModuleName}}_protocol.py
  string_enum.ssp / int_enum.ssp
    → {{smithyNamespaceDir}}/{{enumFileName}}.py   (Scala side path; not in outputs.json)
  tests/conftest.py
    → <testOutputDir>/conftest.py
  sqlite/service_aiosqlite.ssp
    → {{smithyNamespaceDir}}/sqlite/{{serviceModuleName}}_aiosqlite.py
  sqlite/tests/service_derived_sql_integration_tests.ssp
    → <testOutputDir>/{{smithyNamespaceDir}}/sqlite/test_{{serviceModuleName}}_derived_sql.py
  postgres/service_psycopg.ssp
    → {{smithyNamespaceDir}}/postgres/{{serviceModuleName}}_psycopg.py
  postgres/tests/service_derived_sql_integration_tests_postgres.ssp
    → <testOutputDir>/{{smithyNamespaceDir}}/postgres/test_{{serviceModuleName}}_derived_sql.py
```

Models and the service Protocol are shared once under the Smithy namespace (`…/models/` and `…_protocol.py`); driver-specific implementations live under `…/sqlite/` or `…/postgres/`. Integration test templates live under each implementation's `tests/` directory; rendered tests are written under the user-configured `testOutputDir` (required when any deck entry has `artifactKind: "test"`). Bundled artifact ids, template paths, and output paths live in [`templates/python/src/db/outputs.json`](../../templates/python/src/db/outputs.json); [`SqlServiceCodegenDbArtifacts`](../smithplates-sql-service-renderer/src/main/scala/com/jacoby6000/smithplates/sql/service/renderer/SqlServiceCodegenDbArtifacts.scala) loads and filters that deck by enabled dialects. SQL enum files remain a Scala side path (`renderEnumArtifacts`).

Each `@sqlService` produces one artifact set. Templates receive a neutral `TemplateView` enriched by `SqlNeutralServiceTemplateAttributes`, including:

- **models / usedTypes** — every input, output, and error structure referenced by the service (including nested structures), with Smithy optionality and `TypeRenderer` for target-language type syntax
- **operations** — one entry per service operation with flattened top-level input parameters (nested structures stay single typed arguments), output type, error types, and a precomputed response union (`Output | Error1 | …`; `@sqlDeriveSelectOne` uses `Output | None` and does not surface operation errors in generated Python)
- **sql** (when an operation matches a derived query by shape id) — rendered SQL statement, bind-parameter order, execution mode, and row-mapping metadata for `@sqlDeriveInsert`, `@sqlDeriveUpdate`, `@sqlDeriveDelete`, and `@sqlDeriveSelectOne`

Bundled templates (under `python/src/db/`):

| `artifactKind` | Template | Default `outputPath` | Purpose |
|----------------|----------|----------------------|---------|
| `src` | `models/models.ssp` | `{{smithyNamespaceDir}}/models/{{serviceModuleName}}_models.py` | `@dataclass` models (shared) |
| `src` | `service_protocol.ssp` | `{{smithyNamespaceDir}}/{{serviceModuleName}}_protocol.py` | async `Protocol` interface (shared) |
| `src` | `sqlite/service_aiosqlite.ssp` | `{{smithyNamespaceDir}}/sqlite/{{serviceModuleName}}_aiosqlite.py` | `aiosqlite.Connection` implementation (when `sql.sqlite.enable` is `true`) |
| `src` | `postgres/service_psycopg.ssp` | `{{smithyNamespaceDir}}/postgres/{{serviceModuleName}}_psycopg.py` | `psycopg.AsyncConnection` implementation (when `sql.postgres.enable` is `true`) |
| `test` | `sqlite/tests/service_derived_sql_integration_tests.ssp` | `{{smithyNamespaceDir}}/sqlite/test_{{serviceModuleName}}_derived_sql.py` | in-memory SQLite pytest lifecycle tests (under `testOutputDir`) |
| `test` | `postgres/tests/service_derived_sql_integration_tests_postgres.ssp` | `{{smithyNamespaceDir}}/postgres/test_{{serviceModuleName}}_derived_sql.py` | Testcontainers Postgres + psycopg pytest lifecycle tests (under `testOutputDir`) |

Enabled dialects (`sqlite`, `postgres`) select driver-specific templates and placeholder styles (`sqlite` → `?`, `postgres` → `%s`). Derived DML queries are rendered as segment lists with implied bind parameters between segments.

`@sqlJson` columns use per-type `_json_bind_*` / `_read_*` helpers: structures serialize as explicit field objects; unions use Smithy-style single-key discriminators (exactly one member key on read/write). `@sqlTable` row models treat `@required`, `@sqlPrimaryKey`, and database-managed members (`@sqlCreatedTimestamp`, `@sqlAutoUuid`, `@sqlAutoIncrement`, etc.) as non-optional; only members without those traits are typed as `T | None` without field defaults.

`outputPath` patterns support placeholders such as `{{serviceName}}`, `{{serviceClassName}}`, `{{serviceFileName}}`, `{{serviceModuleName}}`, `{{serviceNamespace}}`, `{{serviceShapeId}}`, `{{serviceVersion}}`, and `{{smithyNamespaceDir}}` (see [Custom templates](../../docs/usage/custom-templates.md)).

See [`SqlServiceCodegenRendererSpec`](../smithplates-sql-service-renderer/src/test/scala/com/jacoby6000/smithplates/sql/service/renderer/SqlServiceCodegenRendererSpec.scala) for schema-level checks. Golden SSP output is compared by [`CodegenTemplateTestSuite`](src/test/scala/com/jacoby6000/smithplates/plugin/codegentest/CodegenTemplateTestSuite.scala) (`python/db/sqlite`, `python/db/postgres`, `python/api/fastapi`, and TypeScript HTTP client variants). Fixture layout: [`templates/python/tests/README.md`](../../templates/python/tests/README.md), [`templates/typescript/tests/README.md`](../../templates/typescript/tests/README.md).

## HTTP service codegen

**HTTP service codegen** (`@httpService` IR + Scalate SSP templates → FastAPI routes, protocols, app wiring, WebSocket routes, response helpers, exceptions, clients, and models) is configured under `smithplates.<language>.http.server` / `http.client` (see [`docs/usage/http-plugin.md`](../../docs/usage/http-plugin.md)). [`HttpServiceCodegenRenderer`](../smithplates-http-service-renderer/src/main/scala/com/jacoby6000/smithplates/http/service/renderer/HttpServiceCodegenRenderer.scala) renders decks from [`../../templates/python/src/http/`](../../templates/python/src/http/) (FastAPI server + HTTPX/HTTPX2 client) and [`../../templates/typescript/src/http/`](../../templates/typescript/src/http/) (axios/fetch client). Artifact lists live in each tree's `outputs.json`. Templates receive neutral `TemplateView` attributes (`HttpNeutralModelTemplateAttributes`, `HttpNeutralServiceTemplateAttributes`, `HttpNeutralRouteGroupTemplateAttributes`).

HTTP golden cases live under `templates/python/tests/http-*` and `templates/typescript/tests/http-*` and run through the same `CodegenTemplateTestSuite` as SQL service codegen. Runtime example coverage lives in the Python/TypeScript petstore references and shared HTTP example tests.

### Python validation

Golden **render** comparison runs in Scala (`sbtn "smithplatesPlugin/testOnly *CodegenTemplateTestSuite*"` or `./scripts/run-template-golden-tests.sh`). Golden **execution** (strict **mypy**, **ruff**, **pytest -m integration**) runs via [`language-test-harnesses/python/`](../../language-test-harnesses/python/) against `templates/python/tests/<case>/expected/`. Postgres integration tests spin up `postgres:16-alpine` via `testcontainers[postgres]` (requires Docker). SQLite integration tests use in-memory `aiosqlite`. Requires `uv` on `PATH`.

## Smithy integration

## Build-time generators

Contributor generator tasks are defined on **`smithplatesPlugin`** (also aliased on the root project). [`SmithplatesGenerators`](src/test/scala/com/jacoby6000/smithplates/plugin/generators/SmithplatesGenerators.scala) is the shared entrypoint for all build-time generators.

| Task | Usage |
|------|--------|
| `generateGoldenTemplatesFor` | `sbtn 'generateGoldenTemplatesFor <language> <case-name> [<case-name> ...]'` — writes rendered artifacts into `templates/<language>/tests/<case-name>/expected/` (e.g. `python` or `typescript`) |
