- Use this skill to inspect what a Rails page currently displays, extract HTML content, or verify rendering WITHOUT starting a dev server. Useful for understanding page output before making changes, debugging views, searching for content, or testing that pages work correctly. Provides .claude/skills/render-page/scripts/render.rb for quick page inspection and HTML extraction.
Render Pages Without Starting a Server
Use the .claude/skills/render-page/scripts/render.rb tool to verify page rendering, extract HTML, or search content in rendered pages.
Basic Usage
The script accepts the database either as an argument or via RAILS_APP_DB environment variable:
# Pass database as argument
.claude/skills/render-page/scripts/render.rb db/2025-alexandria-80-s-neon-nights.sqlite3 /people
# Or just the database name
.claude/skills/render-page/scripts/render.rb 2025-alexandria-80-s-neon-nights /people
# Or use environment variable
RAILS_APP_DB=2025-alexandria-80-s-neon-nights .claude/skills/render-page/scripts/render.rb /people
Common operations:
# Check if pages render successfully
.claude/skills/render-page/scripts/render.rb 2025-alexandria-80-s-neon-nights --check /people /heats /solos
# Show summary with page sizes
.claude/skills/render-page/scripts/render.rb 2025-alexandria-80-s-neon-nights /people /heats
# Get full HTML output (single page only)
.claude/skills/render-page/scripts/render.rb 2025-alexandria-80-s-neon-nights --html /solos
# Search for specific content in rendered pages
.claude/skills/render-page/scripts/render.rb 2025-alexandria-80-s-neon-nights --search "Solos" /solos
Script Options
--check- Only check if page renders (exit 0 on success, 1 on failure)--html- Output full HTML content (works with single path only)--search TEXT- Search for specific text in rendered output--verbose, -v- Show detailed information--help, -h- Show help message
Common Workflows
1. Verify Pages Render Successfully
Test multiple pages at once and see their sizes:
.claude/skills/render-page/scripts/render.rb db/DATABASE.sqlite3 /people /heats /solos
For CI/CD pipelines, use --check mode (silent, exit code indicates success):
.claude/skills/render-page/scripts/render.rb db/DATABASE.sqlite3 --check /people /heats /solos
echo $? # 0 = all succeeded, 1 = at least one failed
2. Search for Content in Rendered Pages
Verify specific content appears in a page:
.claude/skills/render-page/scripts/render.rb db/DATABASE.sqlite3 --search "Rhythm Solos" /solos
# Output: ✓ /solos - 'Rhythm Solos' found
3. Extract HTML for Analysis
Save rendered HTML to a file for inspection:
.claude/skills/render-page/scripts/render.rb db/DATABASE.sqlite3 --html /heats > heats.html
Advanced: Custom Scripts with Rails API
For complex custom logic, write a Ruby script using Rails' routing API directly:
# custom_test.rb
env = { "PATH_INFO" => '/heats', "REQUEST_METHOD" => "GET" }
code, headers, response = Rails.application.routes.call(env)
if code == 200
html = response.body.force_encoding('utf-8')
puts "Success: #{html.length} bytes"
else
puts "Error: #{code}"
exit 1
end
Run with bin/run db/DATABASE.sqlite3 custom_test.rb
See lib/tasks/prerender.rake for a production example of this technique.
