how does routes in express work

Vote count:

I recently started working on MEAN stack and using expressjs on the server. In number of tutorials I have read, express js routes are used as

var post = require('./routes/post');
app.get('/post/:post_id', post.get);
app.post('/post/:post_id/comment', post.addComment);
app.del('/post/:post_id/comment', post.removeComment);

But I started using boiler plate code of MEAN.io where the routes are used as

'use strict';

// Articles routes use articles controller
var articles = require('../controllers/articles');
var authorization = require('./middlewares/authorization');

// Article authorization helpers
var hasAuthorization = function(req, res, next) {
    if (req.article.user.id !== req.user.id) {
        return res.send(401, 'User is not authorized');
    }
    next();
};

module.exports = function(app) {

    app.route('/articles')
        .get(articles.all)
        .post(authorization.requiresLogin, articles.create);
    app.route('/articles/:articleId')
        .get(articles.show)
        .put(authorization.requiresLogin, hasAuthorization, articles.update)
        .delete(authorization.requiresLogin, hasAuthorization, articles.destroy);

    // Finish with setting up the articleId param
    app.param('articleId', articles.article);

};

What does get and post both defined on single path do? Actually even to get articles we need to be authorized though authorization.requiresLogin is not mentioned on get of '/articles'.
