When I try to use koa-route 3.2.0 example from their website, I got error message router.routes is not a function
const Koa = require('koa');
const router = require('koa-route');
const app = new Koa();
app.use(logger());
router.get('/users', (ctx, next) => {
ctx.response.body =`<h1>Hello!</h1>`;
});
app.use(router.routes())
.use(router.allowedMethods());
// don't listen to this port if the app is required from a test script
if (!module.parent) {
app.listen(1337);
console.log('listening on port: 1337');
}
I got error message:
app.use(router.routes())

Looks like you've installed the newer version, available at https://github.com/alexmingoia/koa-router/tree/master
You need to use new Router() instead.
Also looks like you're mixing up koa-router with koa-route, which are two different packages.
const Koa = require('koa');
const Router = require('koa-router');
const app = new Koa();
const router = new Router();
router.get('/', function (ctx, next) {
// ctx.router available
});
app
.use(router.routes())
.use(router.allowedMethods());

I am creating an API, so I want to add a user system and validate access to the API.
This would be the middleware for validation:
'use strict'
const jwt = require('jwt-simple');
const moment = require('moment');
const config = require('../settings/config');
function isAuth(req, res, next) {
if (!req.headers.authotization) {
return res.status(403).send({
message: `No tiene autorizacion`
})
}
const token = req.headers.authotization.split(" ")[1];
const payload = jwt.decode(token, user, config.token.secret_token);
if (payload.exp <= moment().unix()) {
return res.status(401).send({
message: 'El token ha expirado'
})
req.user = payload.sub;
next();
}
}
module.exports = isAuth;
while this would be the route:
'use strict'
const express = require('express');
const router = express.Router();
const auth = require('../middlewares/auth');
router.get('/', auth.isAuth, (req, res) => {
res.status(200).send({
message: `Tienes acceso`
})
})
on the other hand, this is my main application settings (app.js):
const express = require('express');
const bodyParser = require('body-parser');
const morgan = require('morgan');
const app = express();
const config = require('./config')
// Middleware
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(morgan('dev'));
// Routes variables
const productRouter = require('../routes/product');
const privateRouter = require('../routes/private');
// Routes uses
app.use('/api/product', productRouter);
app.use('/private', privateRouter);
app.listen(config.app.port, err => {
if (err) throw err;
console.log(`Server listening on port ${config.app.port}`)
})
module.exports = app;
I am getting this error:

Does anybody know what is it due to?
module.exports = isAuth; means you're only exporting the function and nothing else. That means when you do const auth = require('../middlewares/auth');, auth is the actual function, not an object containing isAuth as a property.
So, doing router.get('/', auth, (req, res) => { should work, instead of auth.isAuth which is invalid.
Learn more about modules here: https://js.evie.dev/modules
Yes, you export the function with this code: module.exports = isAuth;
But then you call use it like this: auth.isAuth
Assuming you're doing something like const auth = require('./bin/auth.js'); or whatever
auth would be the function itself -- there will be no isAuth property.
So you should try this:
router.get('/', auth, (req, res) => {
You haven't posted your entire code, so this is just a best guess.
I want to export some module to my app.js and use it. But i catch an exception like:
'getUserFromDB isnt defined'
So, that's my app.js:
var api = require('./routes/API')
app.use(api.router)
And API.js:
const router = require('express').Router()
function getUserFromDB(login){
// some actions
}
router.get('/get-db', (req, res) => {
getUserFromDB('abcde123')
})
module.exports = {
router: router,
getUserFromDB: getUserFromDB
}

I dont know what to do.
Please try the following
const router = require('express').Router()
function getUserFromDB(login){
// some actions
return login;
}
router.get('/get-db', (req, res) => {
res.send(getUserFromDB('abcde123'));
})
module.exports = {
router: router,
getUserFromDB: getUserFromDB
}
Change to the following in app.js
app.use('/', api.router);
const router = require('express').Router()
const getUserFromDB = function(login){
// some actions
}
router.get('/get-db', (req, res) => {
getUserFromDB('abcde123')
})
module.exports = {
router: router,
getUserFromDB: getUserFromDB
}
I want to pass React Component from server-side, which is written in node.js.
Code(server.js):
var ReactDOMServer = require('react-dom/server');
var ReactApp = require('./console/ReactApp');
app.get('*', function(req, res, next){
var reactHtml = ReactDOMServer.renderToString(<ReactApp />);
res.render('index',
{reactOutput: reactHtml});
});
console/ReactApp.js:
var React = require('react');
var ReactApp = React.createClass({
render: function() {
return <div>Hello World</div>;
}
});
module.exports = ReactApp;
In both files, '<>' generated SyntaxError when running node server.js
var reactHtml = ReactDOMServer.renderToString(<ReactApp />);

that's is JSX. You need to transpile it before use or run it with babel-node (the latter is NOT a recommended method).
Or you can use transpiled code like this:
var reactHtml = ReactDOMServer.renderToString(React.createElement(ReactApp));
See full api of React.createElement here
