Add response-handling tests for @fedify/h3 - #1007
Conversation
The package had no test task in deno.json and no test/test:bun scripts in package.json, so mise run test:node, test:bun, and test-each never ran anything for this package. Changelog: none Assisted-by: Claude Code:claude-sonnet-5
integrateFederation() calls event.respondWith() when Fedify handles a request (e.g., a 200 OK ActivityPub response), but this path had no test coverage. Changelog: none Assisted-by: Claude Code:claude-sonnet-5
When Fedify has no matching endpoint, it responds 404 and integrateFederation() must not respond itself so h3's other routes get a chance to handle the request. This had no test coverage. Changelog: none Assisted-by: Claude Code:claude-sonnet-5
When Fedify can't negotiate an acceptable content type, it responds 406. integrateFederation() defers responding and stores the response on event.context so onError() can use it if no other route handles the request. This had no test coverage. Changelog: none Assisted-by: Claude Code:claude-sonnet-5
onError() converts a stored 406 response into the actual response only when h3's own routing also reports 404, so Fedify and app routes negotiate content types correctly together. This had no test coverage. Also adds a regression test verifying integrateFederation() awaits an async contextDataFactory before calling federation.fetch(), mirroring the ordering check CodeRabbit requested on @fedify/express's fedify-dev#985. Changelog: none Assisted-by: Claude Code:claude-sonnet-5

Node.js v26 --experimental-transform-types removed official documentation
💡 Result:
The --experimental-transform-types flag was officially removed in Node.js v26.0.0 [1][2]. This removal was implemented via pull request #61803, which was merged on February 27, 2026 [3]. The decision to remove the flag, rather than stabilizing it, was made because the Node.js project decided to focus on supporting only "erasable" TypeScript syntax (type stripping) by default, rather than supporting full TypeScript transformation (which would include features like enums, namespaces, and parameter properties) [4][5]. Consequently, all code, tests, and documentation related to the --experimental-transform-types flag were removed from the Node.js codebase [3][6]. Users requiring TypeScript transformation features that go beyond simple type stripping are now expected to use alternative tools, as the native support in Node.js is limited to stripping erasable syntax [5]. Version 26.0.0 marked the official removal of the flag, and it remains absent in subsequent releases, including the current v26.7.0 [1][7][8].

Declare the supported Node.js range and keep the test command compatible.
Other Fedify packages support Node.js >=22.0.0, which includes Node.js v26, but @fedify/h3 declares no engines range. Node.js v26 removed --experimental-transform-types, so pnpm test fails before test discovery on Node.js v26+. Use a compatible test runner or constrain the supported range.
