Description

This PR fixes multiple SEO issues detected during the Lighthouse audit.

Fixes Included

  • Added a valid robots.txt file
  • Fixed static file routing conflicts in _redirects
  • Added missing SEO meta tags
  • Improved page metadata for better indexing and social sharing

Root Cause

The SPA catch-all redirect rule was redirecting /robots.txt requests to index.html, causing Lighthouse to detect the robots file as invalid because HTML content was returned instead of plain text.

Additionally, the project was missing a meta description and other important SEO metadata.

Files Modified

  • public/robots.txt
  • public/_redirects
  • index.html

Expected Improvements

  • Better Lighthouse SEO score
  • Proper crawler indexing
  • Improved search engine previews
  • Better social sharing metadata

How Has This Been Tested?

  • Verified /robots.txt returns valid plain text

  • Verified static assets are served correctly

  • Ran Lighthouse SEO audit

  • Confirmed meta tags are present in the document head

  • Confirmed Lighthouse no longer reports:

    • Invalid robots.txt
    • Missing meta description

📝 Walkthrough

Walkthrough

This PR improves site discoverability and maintainability by adding comprehensive SEO metadata to the HTML head (including Open Graph, description, keywords, and canonical URL), creating a robots.txt file with search engine crawling directives, configuring static asset redirect rules, and updating development dependencies for type safety and session management.

Changes

Site Configuration and Dependencies

Layer / File(s) Summary
SEO and Search Engine Configuration
index.html, public/robots.txt, public/_redirects
HTML head expanded with Open Graph metadata, description, keywords, author, robots directives, and canonical URL. robots.txt created with directives allowing root path access, disallowing /api/ and /admin/, setting crawl-delay, and referencing a sitemap. _redirects configured to explicitly self-map static assets (/robots.txt, /favicon.ico, /crl.png, /crl-icon.png, /vite.svg) with 200 responses and prepared SPA catch-all routing infrastructure.
Development Dependencies
package.json
@types/jasmine upgraded from ^5.1.8 to ^5.1.15 and express-session upgraded from ^1.18.2 to ^1.19.0; devDependencies block whitespace normalized.

- Line 15: Replace the placeholder canonical URL in index.html (the link element
with rel="canonical" and href="https://github-tracker.example.com/") with the
actual production origin for the live site (use the PR’s stated live site URL),
keeping the correct scheme and a trailing slash; ensure you update this single
link[href] value (and any other occurrences of that placeholder host in
index.html such as meta tags or alternate links) so search engines receive the
correct canonical host.

In `@package.json`:
- Line 56: The package.json currently lists "express-session" only under
devDependencies which causes runtime failures when dev deps are omitted; move
"express-session" into the top-level "dependencies" section (or run npm install
--save express-session) so backend/server.js can require it and
app.use(session(...)) will work in production; ensure you remove it from
devDependencies to avoid duplication and update package-lock if present.

In `@public/robots.txt`:
- Line 7: Summary: robots.txt points to a placeholder sitemap host; update it to
the real production sitemap URL. Replace the line "Sitemap:
https://github-tracker.example.com/sitemap.xml" with the correct production
sitemap URL used by this site (the real host used elsewhere in the PR) so
crawlers can find the sitemap; ensure the line preserves the "Sitemap: " prefix
and uses the exact production HTTPS URL.

Move express-session from devDependencies to dependencies to prevent runtime startup failures.

backend/server.js requires express-session and registers app.use(session(...)) during server startup, but package.json lists express-session only under devDependencies (line 56). With dev deps omitted (e.g., npm ci --omit=dev), the server will fail with MODULE_NOT_FOUND.
