Forward request to alternate request handler instead of redirect

Question

I\'m using Node.js with express and already know the existence of response.redirect().

However, I\'m looking for more of a forward() funct

Answer 1

For Express 4+

Using the next function does not work if the next handler is not added in the right order. Instead of using next, I use the router to register the handlers and call

app.get("/a/path", function(req, res){
    req.url = "/another/path";
    app.handle(req, res);
}

Or for HTML5 mode of React/Angular

const dir = process.env.DIR || './build';

// Configure http server
let app = express();
app.use('/', express.static(dir));

// This route sends a 404 when looking for a missing file (ie a URL with a dot in it)
app.all('/*\.*', function (req, res) {
    res.status(404).send('404 Not found');
});

// This route deals enables HTML5Mode by forwarding "missing" links to the index.html
app.all('/**', function (req, res) {
    req.url = 'index.html';
    app.handle(req, res);
});
