fix(platform): apply SSR route policies before rendering by benpsnyder · Pull Request #2523 · analogjs/analog

benpsnyder · 2026-09-07T01:49:12Z

PR Checklist

Part of #2522.

On alpha, /client is server-rendered even though its Nitro route rule sets ssr: false. The renderer reads response headers before Nitro applies the matched rule's headers. This patch reads the matched policy before rendering and lets an explicit ssr: true reset an inherited opt-out.

The unchanged JSON-LD E2E test reproduces this on untouched alpha. It also blocks compiler PR analogjs/analog#2520. This small prerequisite keeps the route-policy fix in the platform workstream requested in Brandon's review of analogjs/analog#2516.

Affected scope

Primary scope: platform.
Supporting scope: SSR documentation and the shared Node/Nx Agent bootstrap prerequisites.

What is the new behavior?

nitro({
  routeRules: {
    '/admin/**': { ssr: false },
    '/admin/help': { ssr: true },
  },
});

The parent rule returns the client shell. The more specific help route renders on the server. Other rule headers are retained, and the existing response-header fallback remains available when no matched SSR policy exists.

Caller-provided x-analog-no-ssr is removed before internal renderer dispatch. For example, a request to an explicitly SSR-enabled /products/1 still returns server-rendered HTML when it supplies x-analog-no-ssr: true; /cart configured with ssr: false still returns the client shell when the caller supplies false. Cloning preserves the request URL/query, method/body, custom headers, runtime context, and abort signal/reason without changing the incoming headers.

The Node pin is shared through .node-version and .nvmrc; Nx Agents install the configured Playwright browsers. The base's obsolete pnpm cypress install command fails because Cypress is absent. These small bootstrap prerequisites are also present in the compiler PR; including them here makes this prerequisite independently executable in CI.

Test plan

Verified head: 535fb080ee9b29931a6f6232a08f532213f164f0; current CI checks. Local qualification used Linux, Node 24.15.0, pnpm 10.33.0, and NX_DAEMON=false NX_NO_CLOUD=true. These are recorded executable results; this description update does not change source.

pnpm nx test platform: 396 tests pass after the caller-header repair.
pnpm nx lint platform, pnpm nx lint analog-app-e2e, and pnpm nx run analog-app-e2e:typecheck pass.
Committed-adapter reproduction invokes SSR with and without the caller hint, matching the preserved integration reference. Request regressions cover GET/HEAD/POST, URL/query, body, custom headers, runtime identity, and abort state/reason.
Untouched alpha at 4225f4509: the existing only injects JSON-LD client-side for no-SSR routes assertion fails on the raw HTTP response; the same assertion passes unchanged after the route-policy repair.
Before header filtering was restored, five new focused regression assertions failed while the four existing route-policy tests passed.
pnpm nx run analog-app-e2e:e2e --args='ssr-policy.spec.ts --reporter=line': both HTTP regressions pass, including the application build and prerequisites.
Current-head main CI runs the full application E2E suite, and Windows/build/preview checks pass.
Changed-file formatting and git diff --check pass.

Does this PR introduce a breaking change?

Yes
No

Existing ssr configuration now controls rendering at the intended point. No intended public API removal.

Other information

Targets alpha directly and can merge before the compiler and toolchain contributions. This PR does not close issue 2522: SSR entry discovery and buffered error handling remain in its separate follow-up.

Prepared with OpenAI Codex; the failure was reproduced on an untouched baseline and verified against the built application after repair.

[optional] What gif best describes this PR or how it makes you feel?

Not applicable.

Read matched policies before header middleware and retain explicit child SSR opt-ins. Refs analogjs#2522. Includes the shared CI bootstrap prerequisites. Co-Authored-By: OpenAI Codex <noreply@openai.com>

📝 Walkthrough

Walkthrough

The Node.js pin now uses 24.15.0, and contributor setup documentation references .node-version. The hybrid-rendering documentation and test app use Analog v3 Nitro route-rule configuration. Nitro now resolves route-rule headers before response headers, resets headers for explicit SSR rules, and removes caller no-SSR headers before forwarding requests. Unit and end-to-end tests cover enabled, disabled, inherited, and normal SSR paths.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 535fb

This change makes SSR route policies take precedence over caller hints, preserving configured server-rendered and client-rendered behavior. Current coverage supports the intended outcomes, with no remaining merge-blocking risk identified.

Add a Nitro request-level route-rule test.

Lines [16]-[25] construct event.context.routeRules.headers directly. This verifies renderer precedence, but it does not verify that Nitro populates this field for a matched parent ssr: false rule and a more-specific child ssr: true rule before response middleware runs. Add one request-level test through Nitro's route matcher. Keep these unit cases for renderer precedence.
