Is it possible to rewrite the URL path using node.js?(I'm also using Express 3.0)
I've tried something like this:
req.url = 'foo';
But the url continues the same

Sure, just add a middleware function to modify it. For example:
app.use(function(req, res, next) {
if (req.url.slice(-1) === '/') {
req.url = req.url.slice(0, -1);
}
next();
});
This function removes the trailing slash from all incoming request URLs. Note that in order for this to work, you will need to place it before the call to app.use(app.router).

I think it is working fine, but the path on the browser continues the same... Is it possible to rewrite the URL on the user browser too or just using res.redirect ?

If you want to modify the URL in the browser, I think you need to redirect the user. See the answer and comments here.

In Express 4 (and maybe earlier), this no longer works. The
Request instance defines the req property as not writable.David Weldon
@PhpMyCoder could you add an answer showing how to do this in more modern versions? I haven't been using express for a while so I'm not sure how to fix this.

Turns out I can't read. For some reason when I skimmed over this question I read
req.path not req.url. req.url is a property of Http.IncomingMessage so it can be set. Your original answer was correct. My apologies! |
A good idea should be to update the path too. My method suggestions:
app.use(function(req, res, next) {
console.log("request", req.originalUrl);
const removeOnRoutes = '/not-wanted-route-part';
req.originalUrl = req.originalUrl.replace(removeOnRoutes,'');
req.path = req.path.replace(removeOnRoutes,'');
return next();
});
By this way /not-wanted-route-part/users will became /users

in [email protected] i get the following TypeError: Cannot set property path of #<IncomingMessage> which has only a getter
you need override some properties of req (IncomingMessage in NodeJs):
- url
- path
- search
- query

function changeUrl(req, url) {
const parsedUrl = new URL(url);
req.url = url;
req.originalUrl = url;
req.path = parsedUrl.pathname;
req.search = parsedUrl.search;
req._parsedUrl = parsedUrl;
const query = {};
for(const entry of parsedUrl.searchParams) {
query[entry[0]] = entry[1];
}
req.query = query;
}
