### Minor Changes - [#349](https://github.com/cloudflare/chanfana/pull/349) [`98a3ba0`](https://github.com/cloudflare/chanfana/commit/98a3ba006798c0fbf7df859de68f558f8fedcdec) Thanks [@G4brym](https://github.com/G4brym)! - Refresh dependency security, reproducible CI installs, and explicit test tooling. ### Patch Changes - [#347](https://github.com/cloudflare/chanfana/pull/347) [`deb4a5d`](https://github.com/cloudflare/chanfana/commit/deb4a5d8538e811dfdcf07d0b1ad3bbc993df91c) Thanks [@G4brym](https://github.com/G4brym)! - Preserve the fetched object when preparing update data for lifecycle hooks. - [#346](https://github.com/cloudflare/chanfana/pull/346) [`7f1f15a`](https://github.com/cloudflare/chanfana/commit/7f1f15a8c7e7cf5adfb6fd8d4d3074fe435764b9) Thanks [@winklemad](https://github.com/winklemad)! - Reject partially numeric query, path, and header parameters instead of silently accepting their numeric prefix.

### Minor Changes - [#316](https://github.com/cloudflare/chanfana/pull/316) [`d30cc36`](https://github.com/cloudflare/chanfana/commit/d30cc3662db1b6152f01e1b296cde294cc67939c) Thanks [@G4brym](https://github.com/G4brym)! - Add customizable pagination and ordering parameter names to ListEndpoint via `pageFieldName`, `perPageFieldName`, `orderByFieldName`, and `orderByDirectionFieldName` class properties. **Breaking change for subclasses overriding `optionFields`:** `optionFields` is now a computed getter derived from the four `*FieldName` properties. Subclasses that previously overrode `optionFields` directly should instead override the individual field name properties. - [#317](https://github.com/cloudflare/chanfana/pull/317) [`39c89d2`](https://github.com/cloudflare/chanfana/commit/39c89d29e7ff28f5c9ce8c3b76540450d7461818) Thanks [@G4brym](https://github.com/G4brym)! - Add `validateResponse` router option to validate and sanitize response bodies against their Zod schemas at runtime. When enabled, responses are parsed through `z.object().parseAsync()`, which strips unknown fields and validates required fields/types. This prevents accidental data leaks (e.g., internal fields like `passwordHash` reaching the client) and catches handler bugs where the response doesn't match the declared schema. ```typescript const router = fromHono(app, { validateResponse: true }); ``` **Behavior:** - Plain object responses are validated against the `200` response schema - `Response` objects with `application/json` content are cloned, validated, and reconstructed with corrected headers - Non-JSON responses and responses without a matching Zod schema are passed through unchanged - Validation failures return `500 Internal Server Error` (code `7013`) and log the full error via `console.error` **New exports:** - `ResponseValidationException` — thrown when a handler's response doesn't match its declared schema (status 500, code 7013, `isVisible: false`) - [#315](https://github.com/cloudflare/chanfana/pull/315) [`47d304a`](https://github.com/cloudflare/chanfana/commit/47d304a3ff48740344aaf1f50979fb7c9ab111ca) Thanks [@G4brym](https://github.com/G4brym)! - Add `SerializerContext` parameter to auto endpoint serializer function, providing access to filters and options for context-aware serialization. The serializer signature changes from `(obj: object) => object` to `(obj: object, context?: SerializerContext) => object`. The `SerializerContext` type contains: - `filters` — `Array`: the active filter conditions for the current request - `options` — pagination and ordering options (`page`, `per_page`, `order_by`, `order_by_direction`) **Context passed per endpoint type:** | Endpoint | Context | | ----------------------------------- | ---------------------- | | `ListEndpoint` / `ReadEndpoint` | `{ filters, options }` | | `UpdateEndpoint` / `DeleteEndpoint` | `{ filters }` | | `CreateEndpoint` | `{ filters: [] }` | ```typescript const meta = { model: { schema: UserSchema, primaryKeys: ["id"], tableName: "users", serializer: (obj: any, context?: SerializerContext) => { const hasRoleFilter = context?.filters?.some((f) => f.field === "role"); // Conditionally include fields based on active filters return hasRoleFilter ? obj : omit(obj, ["role"]); }, }, }; ``` **New exports:** - `SerializerContext` — type for the serializer's second parameter ### Patch Changes - [#335](https://github.com/cloudflare/chanfana/pull/335) [`028c256`](https://github.com/cloudflare/chanfana/commit/028c2562e6ab0531dd2648a556042445398896da) Thanks [@andrewheberle](https://github.com/andrewheberle)! - Fix: Error from Zod transform is returning 500 instead of 400 - [#328](https://github.com/cloudflare/chanfana/pull/328) [`662ff72`](https://github.com/cloudflare/chanfana/commit/662ff7259819b1ba1038219a4331c69322989c8c) Thanks [@G4brym](https://github.com/G4brym)! - Include CHANGELOG.md in the npm package so AI agents and tools can read the project's change history. Also add a changelog page to the documentation site.

### Patch Changes - [#325](https://github.com/cloudflare/chanfana/pull/325) [`c182e59`](https://github.com/cloudflare/chanfana/commit/c182e594258b306da2a03fdd076f73b1ee0326be) Thanks [@G4brym](https://github.com/G4brym)! - Export `OrderByDirection` type alias (`"asc" | "desc"`) so consumers can import it directly instead of inlining literal unions - [#325](https://github.com/cloudflare/chanfana/pull/325) [`c182e59`](https://github.com/cloudflare/chanfana/commit/c182e594258b306da2a03fdd076f73b1ee0326be) Thanks [@G4brym](https://github.com/G4brym)! - Add `passthroughErrors` option to bypass chanfana's error handling and let errors propagate raw to the framework's error handler ```typescript import { Hono } from "hono"; import { fromHono, ApiException } from "chanfana"; import { ZodError } from "zod"; const app = new Hono(); app.onError((err, c) => { // Errors arrive as raw exceptions — no HTTPException wrapping if (err instanceof ApiException) { return c.json( { ok: false, code: err.code, message: err.message }, err.status as any ); } if (err instanceof ZodError) { return c.json({ ok: false, validationErrors: err.issues }, 400); } return c.json({ ok: false, message: "Internal Server Error" }, 500); }); const openapi = fromHono(app, { passthroughErrors: true }); ```

### Minor Changes - [#314](https://github.com/cloudflare/chanfana/pull/314) [`2408999`](https://github.com/cloudflare/chanfana/commit/24089994dab32ee4a94162f64ff030dc65684ca1) Thanks [@G4brym](https://github.com/G4brym)! - Add `tags` support to auto endpoint `_meta` for OpenAPI tag grouping - [#323](https://github.com/cloudflare/chanfana/pull/323) [`d9b7297`](https://github.com/cloudflare/chanfana/commit/d9b7297632f8fc552f18225aab0e61272cde94d7) Thanks [@G4brym](https://github.com/G4brym)! - Add `handleError` hook, `defaultOrderByDirection`, fix validation error format and D1 update with extra columns - Add `handleError(error)` protected method on `OpenAPIRoute` to transform errors before chanfana formats them. Enables custom error wrapping (e.g., bypassing chanfana's formatter to use Hono's `onError`). - Add `defaultOrderByDirection` property to `ListEndpoint` (defaults to `"asc"`). Allows configuring the default sort direction when `orderByFields` is used. - **Breaking:** Validation errors from `validateRequest()` now return `InputValidationException` format instead of raw Zod issues. This makes the actual response match the OpenAPI schema that chanfana documents. If you parse validation error responses, update your code to use the new shape: **Before:** ```json { "errors": [ { "code": "invalid_type", "expected": "string", "received": "number", "message": "Invalid input: expected string, received number", "path": ["body", "name"] } ], "success": false, "result": {} } ``` **After:** ```json { "errors": [ { "code": 7001, "message": "Invalid input: expected string, received number", "path": ["body", "name"] } ], "success": false, "result": {} } ``` Key differences: `code` is now the numeric `7001` (was a string like `"invalid_type"`), and Zod-specific fields (`expected`, `received`) are no longer included. - `D1UpdateEndpoint.update()` now automatically filters `updatedData` to only include columns defined in the Zod schema. Previously, DB tables with extra columns not in the schema would cause `validateColumnName()` to throw.

## chanfana@3.1.0 ### Minor Changes #### Breaking Changes - **Parameter helpers removed** — `Str()`, `Num()`, `Int()`, `Bool()`, `DateTime()`, `DateOnly()`, `Email()`, `Uuid()`, `Hostname()`, `Ipv4()`, `Ipv6()`, `Ip()`, `Regex()`, `Enumeration()`, and `convertParams()` removed. Use native Zod schemas directly. - **Legacy type support removed** — `legacyTypeIntoZod`, `Arr()`, `Obj()` no longer exported. `contentJson()` now requires a Zod schema. - **D1 error messages sanitized** — Database errors no longer expose internals. Use `constraintsMessages` for user-friendly messages. - **D1 delete/update restricted to primary key filters** — Only `primaryKeys` filters used in WHERE clauses. - **D1 `per_page` capped at 100** — Configurable via `maxPerPage`. - **`raiseUnknownParameters` enforced** — Was previously accepted but non-functional; now active. #### New Features - **10 new exception classes** — `UnauthorizedException` (401), `ForbiddenException` (403), `MethodNotAllowedException` (405), `ConflictException` (409), `UnprocessableEntityException` (422), `TooManyRequestsException` (429), `InternalServerErrorException` (500), `BadGatewayException` (502), `ServiceUnavailableException` (503), `GatewayTimeoutException` (504) - **D1 SQL injection prevention** — `validateSqlIdentifier()`, `validateTableName()`, `validateColumnName()`, `buildSafeFilters()`, `buildPrimaryKeyFilters()`, `getD1Binding()`, `handleDbError()`, and query clause builders - **`Retry-After` header** — Automatically set for `TooManyRequestsException` and `ServiceUnavailableException` - **`getUnvalidatedData()`** — Access raw request data before Zod defaults/transformations - **Hono `basePath()` auto-detection** — Detected automatically; combining `basePath()` and `base` option now throws a descriptive error - **Hono error flow** — Errors flow through Hono's `app.onError` as `HTTPException` instances instead of being caught internally #### Bug Fixes - D1: Prevent unscoped DELETE/UPDATE via `buildPrimaryKeyFilters()` - D1: Fix shared exception instances, empty update SQL, LIKE wildcard escaping - D1: Column names validated against model schema - D1: Read/Delete endpoints use consistent primary key filters and error handling - Fixed: schema generation errors now propagate instead of being silently swallowed - Fixed: `CreateEndpoint` response schema references 201 instead of 200 - Fixed: falsy defaults (`0`, `false`, `""`) correctly applied - Fixed: BigInt coercion uses `BigInt()` directly to avoid precision loss - Fixed: boolean coercion null guard, HEAD request body parsing, YAML URL generation - Fixed: `ApiException` import changed to value import for `instanceof` checks - Fixed: `ReadEndpoint`/`ListEndpoint` document `InputValidationException` in 400 responses #### Improvements - D1 parallel queries via `Promise.all()` for list endpoint - Configurable `maxPerPage` class property - Normalized ORDER BY to lowercase `"asc"`/`"desc"` - `sanitizeOperationId()` removes special characters - Router constructor validation throws if router argument is missing - Error responses include `result: {}` for consistent shape - Comprehensive JSDoc across exception classes, D1 endpoints, and handler methods ### Patch Changes - Include source code, AI coding skills, and documentation in npm package. Added `llms.txt` entry point.
