Use permanent redirects for trailing slash normalization

[riderx]

Problem

Slashless marketing URLs on capgo.app returned HTTP 307 to the trailing-slash form, which can split SEO signals from explicit 301 redirects elsewhere (for example /capawesome/).

Root cause

The web app uses Cloudflare Workers static assets (wrangler.jsonc assets binding). Default html_handling (auto-trailing-slash) issues 307 when a path maps to a folder index.html (Astro trailingSlash: 'always'). The worker runs first (run_worker_first: true) and forwards slashless page URLs to ASSETS.fetch, so clients see that temporary redirect.

Fix

• Add permanentTrailingSlashLocation() in apps/shared/trailingSlashRedirect.ts and return 301 when ASSETS.fetch responds with 307 that only adds a trailing slash (query string preserved via redirectToPath).
• Skip static files (last path segment contains .) and /api/*.
• This keeps existing _redirects behavior for slashless sources such as /self-hosted-capgo (still 302 to docs).
• Set html_handling: "force-trailing-slash" in apps/web/wrangler.jsonc to align with Astro.
• Tests in apps/web/test/trailing-slash-redirect.test.js.
• Also fix a truncated \ud83d... escape in github-releases.json that broke Vite JSON parsing in CI.

Verified status codes

Before (production, 2026-10-18):

curl -sI https://capgo.app/pricing
HTTP/2 307
location: /pricing/

curl -sI https://capgo.app/capawesome/
HTTP/2 301
location: https://capgo.app/alternatives/capawesome/

After (local worker tests):

bun test apps/web/test/trailing-slash-redirect.test.js
# ASSETS 307 /pricing/ -> worker 301 Location: https://capgo.app/pricing/
# /self-hosted-capgo stays 302 to /docs/plugins/updater/self-hosted/getting-started/

Preview deploy should show 301 for slashless page URLs such as /pricing and /fr/pricing.

Summary by CodeRabbit

• Bug Fixes
  • Page URLs without a trailing slash now redirect permanently to the slash-ending version, preserving query strings and fragments. Root paths, API routes, and static asset paths are excluded.
  • Existing redirects that do not meet these conditions, including temporary redirects, remain unchanged.

📝 Walkthrough

The change adds a shared function to select eligible trailing-slash redirects. The web worker applies those redirects after fetching an asset. Asset configuration forces trailing slashes for HTML handling. The capacitor-live-reload 8.0.12 release description is also edited.

Changes: Trailing-slash redirects

Layer / File(s)	Summary
Redirect rules and asset configuration apps/shared/trailingSlashRedirect.ts, apps/web/wrangler.jsonc	The shared function selects targets for eligible same-origin 307 responses. It excludes empty and root paths, paths that already end in /, static-asset paths, and /api paths. Asset configuration sets html_handling to force-trailing-slash.
Worker redirect handling apps/web/src/worker/index.ts, apps/web/test/trailing-slash-redirect.test.js	The worker redirects when the shared function returns a target and tracks the response. redirectToPath copies the request query only when the target has no query. Tests cover target selection, conversion of an eligible ASSETS 307 to a 301, query handling, and preservation of an existing 302 response.

Release description update

Layer / File(s)	Summary
Release description edit apps/web/src/data/github-releases.json	The capacitor-live-reload 8.0.12 description drops the trailing full-changelog link and comparison text.

🟠 Major · Handle /self-hosted-capgo before env.ASSETS.fetch. · index.ts:488-492

apps/web/src/worker/index.ts:488-492
🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Handle /self-hosted-capgo before env.ASSETS.fetch.

/self-hosted-capgo is defined in apps/web/public/_redirects as a 302 redirect, but this worker sends the request to env.ASSETS.fetch(...). Cloudflare does not apply _redirects rules to requests served by Worker code. Because no worker redirect or built asset handles this path, the request can reach the asset-miss response instead of the configured redirect.

Add the legacy redirect handling before the asset fetch and cover this route without mocking the redirect from ASSETS.fetch.
