I am new to Node.js and Express and have tried to go through some of the tutorials. I am able to get basic routing working one level deep (e.g., http://localhost/help), but I'm having trouble getting it to work two levels deep (e.g., http://localhost/help/test).
Here are the relevant lines in app.js:
var help = require('./routes/help');
// also tried this
//var help_test = require('./routes/help/test');
var app = express();
app.use('/help', help);
app.use('/help/test', help.test);
// also tried this
//app.use('/help/test', test);
//app.use('/help/test', help_test);
Under the routes directory I have two files: index.js and test.js.
The index.js consists of:
var express = require('express');
var router = express.Router();
router.get('/', function(req, res) {
res.send('help');
});
module.exports = router;
The test.js file consists of:
var express = require('express');
var router = express.Router();
router.get('/test', function(req, res) {
res.send('help test!');
});
module.exports = router;
Right now I can't start the server due to the configuration in app.js, but any changes I make so that I can start it results in a 404 error when I try to hit http://localhost/help/test
I think some of your confusion is coming from the require in app.js. Let's look at this line:
var help = require('./routes/help');
That line loads the module in routes/help.js. This file is non-existent In your current configuration. Rename your ./routes/index.js file to ./routes/help.js.
Since the above file will only handle routes prefixed with /help and not /help/test, will need to have an additional require:
var help_test = require('./routes/test');
Your app.js file should now have the following:
var help = require('./routes/index');
var help_test = require('./routes/test');
var app = express();
app.use('/help', help);
app.use('/help/test', help_test);
It should be noted that since your help_test module defines a path at /test, and you "use" it at /help/test, the final path of that route will be: /help/test/test.
