libweb

libweb——Web 扩展实用工具。authMiddleware 可验证 JWT 令牌。corsMiddleware 可处理跨域请求。validationMiddleware 可根据 JSON 模式验证请求体。createAuthMiddleware、createCorsMiddleware、createValidation 是用于定制化的工厂函数。适用于使用 Hono 框架保护 HTTP API、进行请求验证，以及处理 CORS 请求。

name: libweb description: > libweb - Web extension utilities. authMiddleware validates JWT tokens. corsMiddleware handles cross-origin requests. validationMiddleware validates request bodies against JSON schema. createAuthMiddleware, createCorsMiddleware, createValidation are factories for customization. Use for securing HTTP APIs, request validation, and CORS handling with Hono framework.

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

javascript

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

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

Pattern 2: Validate requests

javascript

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.
