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

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 want to add logInPageTest.js in a file with the require field, but when I am adding it , it is throwing this error.

Hierarchy is as follows:

Here is my code in index.js file:
require('./test-cases/logInPageTest.js')
Code in logInPageTest.js file:
var wd = require('wd');
var assert = require('assert');
module.exports = function (browser, next) {
maximizeWindow(browser, next);
}
function maximizeWindow(browser, next) {
browser .windowHandle( function (err, handle) {
browser.maximize(handle);
})
}
So, How should I give path to solve the error.
I have my nodejs project, and I want to separate loggers from my route.js to have a clean code.
But I have the next problem, when I try to load my logger to the route.js file, it shows me the next error:

I have the next code inside my loggers dir:
loggers/ticket.js
var log4js = require('log4js');
module.exports = function(){
getTicketLogger = function(){
var logger = null;
log4js.loadAppender('file');
log4js.addAppender(log4js.appenders.file(__dirname + '/../log/ticket.log'), 'ticket-log');
logger = log4js.getLogger('ticket-log');
logger.setLevel('DEBUG');
return logger;
}
};
And my route.js file, has the next head
routes/ticket.js
var Ticket = require('../models/ticket'),
loggers = require('../loggers/ticket.js'),
log = loggers.getTicketLogger();
module.exports = function(app){
}
What I'm doing wrong, and how can improve the code to separate logger from route.js file.
Thanks you.
loggers/ticket.js should return an object that has your getTicketLogger method.
var log4js = require('log4js');
module.exports = function() {
var getTicketLogger = function(){
var logger = null;
log4js.loadAppender('file');
log4js.addAppender(log4js.appenders.file(__dirname + '/../log/ticket.log'), 'ticket-log');
logger = log4js.getLogger('ticket-log');
logger.setLevel('DEBUG');
return logger;
}
return { getTicketLogger: getTicketLogger };
};
Then in routes/ticket.js
var loggers = require('./../loggers/ticket.js')();
var log = loggers.getTicketLogger;
typeof loggers; // => object
typeof log; // => function

The error was in api.js in setting routing:
var router = express().Router;
Just Change it with:
var router = express.Router();
