In NodeJS Express module, specifying path "/" will catch multiple HTTP requests like "/", "lib/main.js", "images/icon.gif", etc
var app = require('express')
app.use('/', authenticate);
In above example, if authenticate
is defined as followed
var authenticate = function(request, response, next) {
console.log("=> path = " + request.path);
next()
}
Then you would see
=> path = /
=> path = /lib/main.js
=> path = /images/icon.gif
Could anyone advise how to define path in Express "app.use" that only catch "/"?
If you are trying to expose static files, people usually place those in a folder called public/
. express has built-in middleware called static
to handle all requests to this folder.
var express = require('express')
var app = express();
app.use(express.static('./public'));
app.use('/', authenticate);
app.get('/home', function(req, res) {
res.send('Hello World');
});
Now if you place images/css/javascript files in public you can access them as if public/
is the root directory
<script src="http://localhost/lib/main.js"></script>
As far as I understand, what you need to do is if you have '/' & '/abc' you need to catch it separately.
This will do the trick:
app.use('/abc', abc);
app.use('/', authenticate);
Means, register the /abc middleware first, then do the / middleware.
There is an issue with this solution also. Here we declared /abc only. So when user calls an unregistered path, then it will hit here. You can make use of originalUrl property in request object to determine its / only or there is something else. Here is the documentation for this : http://expressjs.com/en/api.html#req.originalUrl
if(req.originalUrl !== '/'){
res.status(404).send('Sorry, we cannot find that!');
}
else{
/*Do your stuff*/
