Caution
This PR breaks the SSE surface for @hey-api/client-next, ships zero tests for the URL-ordering fix despite the description claiming three, and bundles an unrelated .gitignore change for a personal tooling file. The core URL-rebuild fix is sound, but the surrounding rewrite introduces several regressions that need to be undone before this can land.
TL;DR — Defers buildUrl() until after request interceptors run so that interceptor mutations to baseUrl/url/path/query are honored, fixing #3803 for client-next. The fix itself is correct, but the diff also rewrites the SSE path incorrectly, drops claimed test coverage, regresses throwOnError behavior, and includes unrelated noise.
Key changes
- Defer
buildUrl()until after request interceptors — the actual fix for #3803;request()now builds the URL on a possibly-mutatedopts. - Rewrite
makeSseFn— interceptor loop moved into the SSEonRequestcallback, but the implementation drops headers/body mutations and thesse.*map is rewired incorrectly (regression). - Inline collapses and comment removal — unrelated reformatting that strips intent-bearing comments and obscures the actual fix.
.gitignore: add.amazonq/rules/gstack.md— unrelated personal tooling entry.- Changeset —
patchbump for@hey-api/openapi-ts.

URL rebuild after interceptors
Before:
buildUrl()ran insidebeforeRequest, so interceptor mutations toopts.baseUrl/url/path/querywere silently dropped.
After:buildUrl(opts)runs afterinterceptors.request.fnsfinish, so URL-shaping interceptors take effect.
This part of the diff matches the fix described in #3803 and is the right shape. The same bug exists symmetrically in client-fetch, client-ofetch, client-axios, client-ky, client-angular, and client-nuxt — fixing them is out of scope for this PR but worth filing as follow-ups so the issue isn't closed prematurely.
SSE map regression
Before:
sse.{delete,get,head,options,patch,post,put,trace}resolved tomakeSseFn(method), returning a streaming SSE client.
After: Same keys resolve tomakeMethodFn(method), returning a regular fetch response.
Every non-connect SSE method is now wired to the plain HTTP request() path. Callers expecting ServerSentEventsResult (a stream async generator) will instead get the request response shape and the as unknown as Client cast hides the resulting type error. This silently breaks every consumer of client.sse.get/post/....
The makeSseFn body itself also has a separate bug: interceptors mutate clonedOpts, but only buildUrl(clonedOpts) is consumed — the init passed to new Request(finalizedUrl, init) is the original requestInit from createSseClient, so interceptor mutations to headers/body/method are lost. The original code rebuilt the Request from a single mutable requestInit object precisely to avoid this.
Missing tests
Before (PR description): "Added 3 test cases to verify interceptor mutations are respected: Test for
baseUrlmutations, Test forpathmutations, Test forquerymutations."
After (actual diff): No new tests.__tests__/client.test.tsis unchanged.
The fix is exactly the kind of behavior change that needs a regression test — without one, the next refactor can re-introduce the bug. Please add the three tests the description claims, asserting on the URL passed to mockFetch after a request interceptor mutates baseUrl, path, and query.
Unrelated .gitignore entry
Before:
.gitignoreends after the snapshot exclusion block.
After: Adds a# gstack (global install)section ignoring.amazonq/rules/gstack.md.
This is a per-developer tooling file and belongs in ~/.config/git/ignore or .git/info/exclude, not the repo's .gitignore. Please drop this hunk.

Regression: every SSE method except connect is now wired to makeMethodFn, which returns a normal HTTP response instead of an SSE stream. Callers of client.sse.get/post/... will silently break — the as unknown as Client cast at the bottom of the file hides the resulting type mismatch. Restore makeSseFn for these entries.

Interceptor mutations to headers, body, signal, etc. are dropped here: clonedOpts is fed to buildUrl, but the init passed to new Request is the original requestInit from createSseClient and never sees the mutations. The previous shape (single requestInit object that the loop mutated, then new Request(requestInit.url, requestInit)) handled this correctly — please restore that pattern, just with buildUrl invoked once after the loop instead of relying on a pre-built url.

as unknown as Client is a code smell here — it's masking the type mismatch introduced by routing SSE methods through makeMethodFn. Once the SSE map is restored, this should go back to as Client.

Behavior change: previously finalError = finalError || {} ran before the throwOnError branch, so a falsy finalError was always thrown as {}. Now throw finalError can throw undefined/null/0/'' if the error chain produced a falsy value. Move the || {} fallback up so both branches see it.

Minor: removing the explicit case 'json': default: emptyData = {} in favor of an unconditional let emptyData: any = {} plus a switch with no default works for today's parseAs values, but loses the explicit default branch. If a future parseAs value is added that should not fall back to {}, this will silently misbehave. Either restore the default case or add a comment noting the fallthrough is intentional.

Stray blank line inside the returned object literal — breaks the alphabetical clustering of method keys.

The deleted comments above this line (// fetch must be assigned here, otherwise it would throw the error: TypeError: Failed to execute 'fetch' on 'Window': Illegal invocation and // remove Content-Type header if body is empty to avoid sending invalid requests) document non-obvious gotchas. Please restore them — they're cheap maintenance signal.
