PR Review: Update Railway Integration Guide for Serverless

Summary

This PR updates the Railway deployment guide to reflect the serverless architecture changes in RivetKit. The main changes include removing the outdated note about not needing to expose a container port and adding a new "Connect to Rivet" step that requires setting up a custom domain.

✅ Positive Observations

1. Improved clarity: The new "Connect to Rivet" step provides clear, actionable instructions for connecting Railway to Rivet
2. Better step organization: Renaming "Verify Deployment" to "Test Your Deployment" is more accurate
3. Necessary update: Removing the note about port exposure aligns with the serverless architecture changes

📝 Suggestions for Improvement

1. Inconsistent Step Title Pattern

The new step title "Connect to Rivet" doesn't follow the same verb pattern as other steps. Consider:

• Current: "Connect to Rivet"
• Suggested: "Connect Rivet to Railway" or "Link Railway to Rivet"

This would match the imperative style of other steps like "Setup Project for Railway", "Deploy to Railway", "Set Environment Variables".

2. Incomplete Final Step

The "Test Your Deployment" step is quite brief compared to the rest of the guide:

Visit your Railway frontend to see everything working.

Consider adding more specific verification steps, similar to the Vercel guide's "Connect and Verify" step. For example:

• What should users expect to see when visiting their frontend?
• How can they verify actors are connected?
• Should they check the Rivet dashboard for confirmation?

3. Missing Context for URL Path

The instruction to append /api/rivet to the Railway domain assumes users understand this routing convention. Consider adding a brief explanation or note about why this path is used, especially since this might vary based on the user's application setup.

4. Consistency with Other Guides

Comparing to the Vercel guide (which has a "Connect and Verify" step), the Railway guide could benefit from:

• Mentioning the Rivet dashboard location for connection status
• Providing a success confirmation message
• Explaining what "Done" accomplishes

5. Link Verification Needed

Line 7 mentions "RivetKit Railway template" but the link is empty (). This should either:

• Include the actual template URL
• Remove the link if the template doesn't exist yet
• Add a TODO comment if the template is planned

🔍 Code Quality Assessment

Strengths:

• Clear, numbered instructions
• Appropriate formatting with bold text for UI elements
• Good use of examples (e.g., my-app.railway.app)

Areas for Enhancement:

• Step title consistency
• More detailed verification instructions
• Better explanation of the /api/rivet path convention

🎯 Testing Considerations

This is documentation-only change, but consider:

• Having someone unfamiliar with Railway follow these steps to identify any gaps
• Verifying that the /api/rivet path is correct for all Railway deployments
• Confirming the networking settings path is accurate in Railway's current UI

🔒 Security & Performance

No security or performance concerns for this documentation change.

📊 Overall Assessment

This is a good update that addresses an important architectural change. The documentation now correctly guides users through the serverless deployment flow. With the minor improvements suggested above, this guide would be even more helpful for new users.

Recommendation: Approve with minor suggestions for enhancement.

---

Note: This review focuses on improving user experience and documentation clarity. The changes are functionally correct and align with the serverless architecture update.
