Express - Mini Project - Library (part 2 routes)

Overview

Add some test data after creating the models

Create a route-handler callback function

/express-locallibrary-tutorial  //the project root
  /controllers
    authorController.js
    bookController.js
    bookinstanceController.js
    genreController.js
    
/express-locallibrary-tutorial //the project root
  /routes
    index.js
    users.js
    catalog.js

authorController.js

var Author = require('../models/author');

// Display list of all Authors.
exports.author_list = function(req, res) {
    res.send('NOT IMPLEMENTED: Author list');
};

// Display detail page for a specific Author.
exports.author_detail = function(req, res) {
    res.send('NOT IMPLEMENTED: Author detail: ' + req.params.id);
};

// Display Author create form on GET.
exports.author_create_get = function(req, res) {
    res.send('NOT IMPLEMENTED: Author create GET');
};

// Handle Author create on POST.
exports.author_create_post = function(req, res) {
    res.send('NOT IMPLEMENTED: Author create POST');
};

// Display Author delete form on GET.
exports.author_delete_get = function(req, res) {
    res.send('NOT IMPLEMENTED: Author delete GET');
};

// Handle Author delete on POST.
exports.author_delete_post = function(req, res) {
    res.send('NOT IMPLEMENTED: Author delete POST');
};

// Display Author update form on GET.
exports.author_update_get = function(req, res) {
    res.send('NOT IMPLEMENTED: Author update GET');
};

// Handle Author update on POST.
exports.author_update_post = function(req, res) {
    res.send('NOT IMPLEMENTED: Author update POST');
};

catalog.js

var express = require('express');
var router = express.Router();

// Require controller modules.
var book_controller = require('../controllers/bookController');
var author_controller = require('../controllers/authorController');
var genre_controller = require('../controllers/genreController');
var book_instance_controller = require('../controllers/bookinstanceController');

/// BOOK ROUTES ///

// GET catalog home page.
router.get('/', book_controller.index);

// GET request for creating a Book. NOTE This must come before routes that display Book (uses id).
router.get('/book/create', book_controller.book_create_get);

// POST request for creating Book.
router.post('/book/create', book_controller.book_create_post);

// GET request to delete Book.
router.get('/book/:id/delete', book_controller.book_delete_get);

// POST request to delete Book.
router.post('/book/:id/delete', book_controller.book_delete_post);

// GET request to update Book.
router.get('/book/:id/update', book_controller.book_update_get);

// POST request to update Book.
router.post('/book/:id/update', book_controller.book_update_post);

// GET request for one Book.
router.get('/book/:id', book_controller.book_detail);

// GET request for list of all Book items.
router.get('/books', book_controller.book_list);

Update the index route module

// GET home page.
router.get('/', function(req, res) {
  res.redirect('/catalog');
});

Route Test

http://localhost:3000/
/catalog
/catalog/books
/catalog/bookinstances/
/catalog/authors/
/catalog/genres/
/catalog/book/123
/catalog/book/create

Result for http://localhost:3000/catalog/books
