Build Expo API Routes
Expo Router API routes can be confusing when secrets, deployment, and runtime limits are involved. This skill gives practical patterns for building, testing, and deploying routes on EAS Hosting.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "expo-api-routes" from https://skillstore.io/skills/expo-expo-api-routes.md and its manifest at https://skillstore.io/api/skills/expo-expo-api-routes/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "expo-api-routes". A developer asks where to put a new users endpoint in an Expo Router project.
Expected outcome:
The response identifies the route file location, supported URL path, needed methods, validation steps, and a local testing command.
Using "expo-api-routes". A team wants to hide a weather service key from a React Native screen.
Expected outcome:
The response recommends a server-side proxy route, an environment variable name, client request behavior, and safe error handling.
Using "expo-api-routes". A release owner asks whether API routes are ready for EAS Hosting.
Expected outcome:
The response checks deployment prerequisites, runtime limits, secret storage, unsupported Node APIs, and route testing coverage.
Security Audit
SafeReviewed SKILL.md and found the static alerts are caused by Markdown examples, placeholder secret names, local test URLs, and sample API route code. No evidence found of prompt injection, malware behavior, secret exfiltration, or automatic command execution.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Add Server Logic to an Expo App
Create API routes for validation, data access, and mobile app features that need server execution.
Protect Third-Party API Keys
Move OpenAI, Stripe, weather, or database keys into server-side route handlers instead of client code.
Prepare Routes for EAS Hosting
Check local testing commands, deployment steps, and Cloudflare Workers limits before shipping.
Try These Prompts
Use this skill to design a basic Expo Router API route for my app. Include the route file path, supported method, response shape, and local test steps.
Use this skill to plan an Expo API route that accepts request data. Explain validation, error responses, and which HTTP status codes to use.
Use this skill to design an Expo API route that calls a third-party service with a server-side secret. Include environment variable setup and client call guidance.
Use this skill to review my Expo API route plan for EAS Hosting. Check route structure, authentication, CORS, runtime limits, deployment steps, and missing safeguards.
Best Practices
- Keep secrets in server environment variables and never in client code.
- Validate and sanitize request data before database writes or external API calls.
- Test routes locally before deploying them to EAS Hosting.
Avoid
- Using API routes for public static data that needs no server logic.
- Putting API keys or database credentials inside React Native components.
- Assuming Node filesystem or native modules are available on EAS Hosting.
