        res.json({
            status: 200,
            message: "Hello, Shits!"
        })
    })

    return router

const headers = (req, res, next) => {
    res.set('Access-Control-Allow-Methods', 'GET,POST');
    next()
}

const unauthorize = (err, req, res, next) => {
    if (err.name === 'AuthenticationError') {
        // Send a customized response for authentication failure
        return res.status(err.status).json({ 
            status: err.status,
            message: 'Invalid Authorization header supplied.\nPlease contact support or check your credentials.'

    enableCors: true, 
    // lastRouteHandler: invalid, // Method for handling 404 not found routes
    // docsModule: swaggerDoc, // Swagger Docs
    enableLog: true, // Log option can also accept LogOption { path: '/logs' }
    // jwtStrategy: jwtStrategy // JWT Strategy, this package uses passport-jwt for authentication, if this provided as option make sure you enable `registerAuthenticationRoute`

const apiInstance = new ExpressApi(apiOptions)
apiInstance.registerRoutesGroup(
        "/api",
        {
            method: app, args: undefined, name: 'app'
        }
    )
