express route file code example
Example 1: express get all routes and methods
function print (path, layer) {
if (layer.route) {
layer.route.stack.forEach(print.bind(null, path.concat(split(layer.route.path))))
} else if (layer.name === 'router' && layer.handle.stack) {
layer.handle.stack.forEach(print.bind(null, path.concat(split(layer.regexp))))
} else if (layer.method) {
console.log('%s /%s',
layer.method.toUpperCase(),
path.concat(split(layer.regexp)).filter(Boolean).join('/'))
}
}
function split (thing) {
if (typeof thing === 'string') {
return thing.split('/')
} else if (thing.fast_slash) {
return ''
} else {
var match = thing.toString()
.replace('\\/?', '')
.replace('(?=\\/|$)', '$')
.match(/^\/\^((?:\\[.*+?^${}()|[\]\\\/]|[^.*+?^${}()|[\]\\\/])*)\$\//)
return match
? match[1].replace(/\\(.)/g, '$1').split('/')
: '<complex:' + thing.toString() + '>'
}
}
app._router.stack.forEach(print.bind(null, []))
Example 2: express() vs express.router()
var express = require('express'),
dogs = require('./routes/dogs'),
cats = require('./routes/cats'),
birds = require('./routes/birds');
var app = express();
app.use('/dogs', dogs);
app.use('/cats', cats);
app.use('/birds', birds);
app.listen(3000);
Example 3: express() vs express.router()
var express = require('express');
var router = express.Router();
router.get('/', function(req, res) {
res.send('GET handler for /dogs route.');
});
router.post('/', function(req, res) {
res.send('POST handler for /dogs route.');
});
module.exports = router;
