libweb Skill

When to Use

Adding authentication to HTTP endpoints
Configuring CORS for API access
Validating request payloads
Building secure REST APIs with Hono

Key Concepts

authMiddleware: Validates JWT tokens from Authorization header.

corsMiddleware: Handles preflight requests and CORS headers.

validationMiddleware: Validates request body against JSON schema.

Usage Patterns

Pattern 1: Secure endpoint

import { authMiddleware, corsMiddleware } from "@copilot-ld/libweb";

app.use(corsMiddleware({ origins: ["http://localhost:3000"] }));
app.use("/api/*", authMiddleware(authConfig));

Pattern 2: Validate requests

import { validationMiddleware } from "@copilot-ld/libweb";

const schema = {
  type: "object",
  required: ["message"],
  properties: { message: { type: "string", maxLength: 1000 } },
};

app.post("/api/chat", validationMiddleware(schema), handler);

Integration

Used by Web and API extensions. Works with Hono framework middleware pattern.
