feat: srvx fetch

[pi0]

A new CLI mode that allows you to directly invoke your server's fetch handler without starting an HTTP server.

This is useful for testing, debugging, and scripting and also specially for coding agents to test any server or route handler without actually running a server!

Works with any format also! Fetchable servers (H3, Hono, Elysia) or Node servers even (Express, Fastify).

Usage

srvx fetch [path]              # Fetch from default entry
srvx fetch /api/users          # Fetch a specific path
srvx fetch -X POST /api/users  # POST request
srvx fetch -H "Content-Type: application/json" /api  # With headers
srvx fetch -d '{"name":"foo"}' /api  # With request body
echo '{"data":1}' | srvx fetch -d @- /api  # Body from stdin
srvx fetch -d @payload.json /api  # Body from file
srvx fetch -v /api/users       # Verbose output (show headers)

Options

Flag	Description
-X, --request <method>	HTTP method (defaults to GET, or POST if body provided)
-H, --header <header>	Add header (format: "Name: Value", repeatable)
-d, --data <data>	Request body (use @- for stdin, @file for file)
-v, --verbose	Show request and response headers

Highlights

• No server required — directly calls your fetch handler for rapid testing
• Streaming support — responses are streamed to stdout with proper encoding
• curl-like interface — familiar flags for HTTP method, headers, and body
• Stdin/file input — pipe data or read from files with @- and @filename syntax
