How to make custom error handler

// create app
const App = require('yeps');
const app = new App();
const Router = require('yeps.router');
const router = new Router();

// add middlewares
app.all([...]);

// add router
router.catch().then(async (ctx) => {
    ctx.res.statusCode = 200;
    ctx.res.end('Homepage');
});

app.then(router.resolve());

// 404 error handler
app.then(async (ctx) => {
    ctx.res.statusCode = 404;
    ctx.res.end('Not Found');
});

// 500 error handler
app.catch(async (err, ctx) => {
    ctx.res.statusCode = 500;
    ctx.res.end('Internal Server Error');
});

HTTP response message and status code

app.then(async (ctx) => {
    const err = new Error();
    err.code = 403;
    
    return Promise.reject(err);
});

And you will see http response 403 with message Forbidden.
