* fix: throw on missing middleware/proxy exports instead of failing open
Middleware and proxy files that don't export the expected function
(e.g. misspelled export, wrong named export) were silently skipped,
letting requests through unprotected. This matches Next.js behavior
which throws a ProxyMissingExportError in the same scenario.
Changes:
- proxy.ts files now require 'proxy' or 'default' export
- middleware.ts files now require 'middleware' or 'default' export
- All 3 code paths updated (Pages dev, Pages prod, App Router)
- Added resolveMiddlewareHandler() with file-type-aware validation
- Ported test cases from Next.js proxy-missing-export test suite
- Updated AGENTS.md: added required step to search Next.js tests
Ported from Next.js: test/e2e/app-dir/proxy-missing-export/
https://github.com/vercel/next.js/blob/canary/test/e2e/app-dir/proxy-missing-export/proxy-missing-export.test.ts
* fix: update export precedence test to match Next.js behavior (named > default)
* fix: use ?? instead of || in generated middleware export resolution for consistency
Matches the shared resolveMiddlewareHandler() which uses nullish
coalescing. No behavioral difference since typeof check catches
all cases, but keeps the three code paths consistent.
* Skip deploy previews for fork PRs that lack Cloudflare secrets
Fork PRs don't have access to repository secrets (CLOUDFLARE_API_TOKEN,
CLOUDFLARE_ACCOUNT_ID), so deploy/smoke-test/comment steps always fail.
Add a fork detection condition to skip these steps gracefully. The build
steps still run, so example builds are still validated for fork PRs.
* Run safe CI for external contributors, add /deploy-preview slash command
Switch ci.yml from pull_request to pull_request_target so lint, typecheck,
vitest, and e2e run automatically for fork PRs without needing approval.
No secrets are used, so this is safe with untrusted code.
Add a /deploy-preview slash command workflow that lets maintainers trigger
deploy previews on fork PRs. Gated by author_association (org members,
collaborators, repo owners only).
Cloudflare employees who push branches to the main repo continue to get
automatic deploy previews via the existing deploy-examples.yml workflow.
* Revert ci.yml to pull_request, skip deploy-examples for fork PRs
Simpler approach: keep ci.yml on pull_request (first-time contributor
approval is fine, avoids cache poisoning concern with pull_request_target).
The actual fix: add a job-level if condition to deploy-examples.yml so the
entire workflow is skipped for fork PRs. This prevents the noisy
failed/skipped deploy checks on external contributor PRs.
Update docs in AGENTS.md and README.md to reflect the approach.
* feat(cli): load .env files with Next.js precedence
* fix(dotenv): address review feedback on .env loading
- Document Vite double-loading interaction in loadDotenv JSDoc
- Fix escaped dollar sign bug ($100 was not unescaped when $ wasn't
followed by a valid variable name)
- Add type cast for parseEnv return value
- Expand test coverage: loadedEnv assertions, production mode
precedence, ${VAR} expansion, escaped dollars, circular refs,
missing files, empty result
- Add getDotenvFiles unit tests for all three modes
- Add 'Prefer Node.js Built-in APIs' guideline to AGENTS.md

* test(dotenv): add cross-file expansion and multi-line value tests
Address review suggestions: test that .env can reference vars from
higher-priority .env.development.local, and that parseEnv handles
quoted multi-line values correctly.
