#Preview Proxy

AIO Sandbox includes built-in proxy endpoints that allow you to preview and test web applications and services directly from your development environment.

#SubDomain Proxy(Recommend)

Any domain name that satisfies the ${port}-${domain} format will be forwarded to the corresponding port within the sandbox.

#SubPath Proxy Types

#Frontend Application Proxy

Access frontend applications using the absolute proxy:

http://localhost:8080/absproxy/{port}/

Use cases:

• React, Vue, Angular applications
• Static site generators
• Development servers with asset bundling
• Any frontend framework with dev server

Example:

# Start a React app on port 3000
cd /workspace/my-react-app
npm start

# Access via proxy
# Browser: http://localhost:8080/absproxy/3000/

#Backend Service Proxy

Access backend services using the relative proxy:

http://localhost:8080/proxy/{port}/

Use cases:

• API servers
• Backend microservices
• Database admin interfaces
• Development tools and utilities

Example:

# Start an Express API on port 4000
cd /workspace/my-api
npm start

# Access via proxy
# API endpoint: http://localhost:8080/proxy/4000/api/users
