Usage

Basic usage

import {createApp, eventHandler, toNodeListener,} from "h3";
import {createServer} from "node:http";
import h3Jwt from "../src/middleware/jwtMiddleware";

const app = createApp();
const port = process.env.PORT || 3000;
const secret = process.env.JWT_SECRET || "secret"

app.use("/", eventHandler((event) => {

app.use('/hello', eventHandler((event) => {
        // console.log(event._headers)
        return {
            message: "Hello World"
        }
    }))


 app.use('/login', eventHandler((event) => {
        // console.log(event._headers)
        return {
            message: "Login"
        }
    }))

    app.use(h3Jwt({
        secretKey: secret,
        getToken: h3Cookie("token"),
        algorithms: ["HS256"]
}))

    app.use('/protected', eventHandler((event) => {

        return {
                message: "Protected route"
            }
}))

}))

Custom Token Extraction

import { h3Jwt, fromHeader, fromCookie } from 'h3-jwt';

app.use('/protected', h3Jwt({
  secret: 'YOUR_SECRET_KEY',
  getToken: (event) => {
    return h3Header() || h3Cookie('cookieName') || h3Query('queryName');
  }
}));
