这篇文章给大家分享的是有关如何使用NodeJS+MongoDB+AngularJS+Bootstrap开发书店项目的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
示例名称：天狗书店
功能：完成前后端分离的图书管理功能，总结前端学习过的内容。
技术：NodeJS、Express、Monk、MongoDB、AngularJS、BootStrap、跨域
效果：
一、Bootstrap
Bootstrap是一个UI框架，它支持响应式布局，在PC端与移动端都表现不错。
Bootstrap是Twitter推出的一款简洁、直观、强悍的前端开发框架。
Bootstrap中包含了丰富的Web组件，根据这些组件，可以快速的搭建一个漂亮、功能完备的网站。
在线可视布局：http://www.ibootstrap.cn/
演示： http://expo.bootcss.com/
中文网：http://www.bootcss.com/
官网：http://getbootstrap.com/
安装：npm install bootstrap@3
1.1、添加引用
也可使用包管理器也可以去官网下载后添加引用。
1.2、在页面中使用BootStrap
添加CSS引用：
<link rel="stylesheet" type="text/css" href="js/bootstrap/dist/css/bootstrap.min.css" />
添加JavaScript引用：
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script> <script src="js/bootstrap/dist/js/bootstrap.min.js" type="text/javascript" charset="utf-8"></script>
在页面中引用BootStrap定义好的样式
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>bootstrap</title> <link rel="stylesheet" type="text/css" href="js/bootstrap/dist/css/bootstrap.min.css" /> </head> <body> <div class="container-fluid"> <div class="row"> <div class="jumbotron"> <h2>Hello, world!</h2> <p>This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information</p> <p> <a class="btn btn-primary btn-lg" href="#" role="button">Learn more</a> </p> </div> </div> <div class="row"> <div class="col-md-6"> <button type="button" class="btn btn-default">默认</button> <button type="button" class="btn btn-primary">主要</button> <button type="button" class="btn btn-success">成功</button> <button type="button" class="btn btn-info">信息</button> <button type="button" class="btn btn-warning">警告</button> <button type="button" class="btn btn-danger">错误</button> <button type="button" class="btn btn-link">链接</button> </div> <div class="col-md-6"> <button type="button" class="btn btn-default btn-lg">默认</button> <button type="button" class="btn btn-default">默认</button> <button type="button" class="btn btn-default btn-sm">默认</button> <button type="button" class="btn btn-default btn-xs">默认</button> </div> </div> </div> <script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script> <script src="js/bootstrap/dist/js/bootstrap.min.js" type="text/javascript" charset="utf-8"></script> </body> </html>
运行结果：
1.3、可视化布局
如果想快速高效的布局可以使用一些在线辅助工具，如：
http://www.ibootstrap.cn/
点击下载可以获得生成的HTML脚本。
二、使用MongoDB创建数据库
2.1、启动MongoDB数据库
数据库的具体安装、配置在前面的章节中已经讲解过，可以参考。
如果服务与配置都没有完成的话可以启动：C:\Program Files\MongoDB\Server\3.4\bin\mongod.exe
2.2、启动数据库GUI管理工具
2.3、创建数据库与集合
在localhost上右键“create database”创建名称为BookStore的数据库。
创建一个用于存放图书的集合名称为books。
在集合中添加5本图书。
db.getCollection('books').insert({id:201701,title:"使用AlarJS开发下一代应用程序",picture:"b1.jpg",price:55.0,author:"brad green"});三、创建一个Express项目
这里使用Eclipse（HBuilder）为开发工具，添加Nodeclipse插件，新增一个Express项目：
3.1、创建app.js
/**
* Module dependencies.
*/
var express = require('express')
, routes = require('./routes')
, books = require('./routes/books')
, http = require('http')
, path = require('path');
var app = express();
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
app.get('/', books.list);
app.get('/books', books.list);
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});四、Monk访问MongoDB数据库
monk是NodeJS平台下访问MongoDB数据库的一个模块。monk访问MongoDB更加方便比NodeJS直接访问。
git仓库地址：https://github.com/Automattic/monk
文档：https://automattic.github.io/monk/
安装：npm install --save monk
4.1、创建连接
const monk = require('monk')
// Connection URL
const url = 'localhost:27017/myproject';
const db = monk(url);
db.then(() => {
console.log('Connected correctly to server')
})4.2、插入数据
const url = 'localhost:27017/myproject'; // Connection URL
const db = require('monk')(url);
const collection = db.get('document')
collection.insert([{a: 1}, {a: 2}, {a: 3}])
.then((docs) => {
// docs contains the documents inserted with added **_id** fields
// Inserted 3 documents into the document collection
}).catch((err) => {
// An error happened while inserting
}).then(() => db.close())
users.insert({ woot: 'foo' })
users.insert([{ woot: 'bar' }, { woot: 'baz' }])4.3、更新数据
const url = 'localhost:27017/myproject'; // Connection URL
const db = require('monk')(url);
const collection = db.get('document')
collection.insert([{a: 1}, {a: 2}, {a: 3}])
.then((docs) => {
// Inserted 3 documents into the document collection
})
.then(() => {
return collection.update({ a: 2 }, { $set: { b: 1 } })
})
.then((result) => {
// Updated the document with the field a equal to 2
})
.then(() => db.close())
users.update({name: 'foo'}, {name: 'bar'})4.4、删除数据
const url = 'localhost:27017/myproject'; // Connection URL
const db = require('monk')(url);
const collection = db.get('document')
collection.insert([{a: 1}, {a: 2}, {a: 3}])
.then((docs) => {
// Inserted 3 documents into the document collection
})
.then(() => collection.update({ a: 2 }, { $set: { b: 1 } }))
.then((result) => {
// Updated the document with the field a equal to 2
})
.then(() => {
return collection.remove({ a: 3})
}).then((result) => {
// Deleted the document with the field a equal to 3
})
.then(() => db.close())
users.remove({ woot: 'foo' })4.5、查找数据
const url = 'localhost:27017/myproject'; // Connection URL
const db = require('monk')(url);
const collection = db.get('document')
collection.insert([{a: 1}, {a: 2}, {a: 3}])
.then((docs) => {
// Inserted 3 documents into the document collection
})
.then(() => collection.update({ a: 2 }, { $set: { b: 1 } }))
.then((result) => {
// Updated the document with the field a equal to 2
})
.then(() => collection.remove({ a: 3}))
.then((result) => {
// Deleted the document with the field a equal to 3
})
.then(() => {
return collection.find()
})
.then((docs) => {
// docs === [{ a: 1 }, { a: 2, b: 1 }]
})
.then(() => db.close())users.find({}).then((docs) => {})
users.find({}, 'name').then((docs) => {
// only the name field will be selected
})
users.find({}, { fields: { name: 1 } }) // equivalent
users.find({}, '-name').then((docs) => {
// all the fields except the name field will be selected
})
users.find({}, { fields: { name: 0 } }) // equivalent
users.find({}, { rawCursor: true }).then((cursor) => {
// raw mongo cursor
})
users.find({}).each((user, {close, pause, resume}) => {
// the users are streaming here
// call `close()` to stop the stream
}).then(() => {
// stream is over
})
//创建的数据库
var monk = require('monk')
var db = monk('localhost:27017/bookstore')
//读取数据：
var monk = require('monk')
var db = monk('localhost:27017/monk-demo')
var books = db.get('books')
books.find({}, function(err, docs) {
console.log(docs)
})
//插入数据：
books.insert({"name":"orange book","description":"just so so"})
//查找数据：
books.find({"name":"apple book"}, function(err, docs) {
console.log(docs)
})
复制代码
五、创建Rest后台服务
在routes目录下增加的books.js文件内容如下：
复制代码
/*
* 使用monk访问mongodb
* 以rest的方式向前台提供服务
*/
//依赖monk模块
var monk = require('monk');
//连接并打开数据库
var db = monk('localhost:27017/BookStore');
//从数据库中获得books集合，类似表，并非所有数据， key
var books = db.get('books');
//列出所有的图书json
exports.list = function(req, res) {
//无条件查找所有的图书，then是当查找完成时回调的异步方法
books.find({}).then((docs) => {
//返回json给客户端
res.json(docs);
}).then(() => db.close()); //关闭数据库
};
//获得最大id
exports.getMax=function(req,res){
//找一个，根据id降序排序，
books.findOne({}, {sort: {id: -1}}).then((bookObj)=>{
res.json(bookObj);
}).then(() => db.close());;
}
//添加图书
exports.add = function(req, res) {
//先找到最大的图书编号
books.findOne({}, {sort: {id: -1}}).then((obj)=>{
//从客户端发送到服务器的图书对象
var book=req.body;
//设置图书编号为最大的图书编号+1
book.id=(parseInt(obj.id)+1)+"";
//执行添加
books.insert(book).then((docs) => {
//返回添加成功的对象
res.json(docs);
}).then(() => db.close());
});
};
//删除图书
exports.del = function(req, res) {
//从路径中取参数id,/:id
var id=req.params.id;
//移除编号为id的图书
books.remove({"id":id}).then((obj)=>{
//返回移除结果
res.json(obj);
}).then(() => db.close());
};
//更新
exports.update = function(req, res) {
//获得提交给服务器的json对象
var book=req.body;
//执行更新,第1个参数是要更新的图书查找条件，第2个参数是要更新的对象
books.update({"id":book.id}, book).then((obj)=>{
//返回更新完成后的对象
res.json(obj);
}).then(() => db.close());
};为了完成跨域请求，修改http头部信息及路径映射，app.js文件如下：
var express = require('express'),
routes = require('./routes'),
books = require('./routes/books'),
http = require('http'),
path = require('path');
var app = express();
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
app.all('*', function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "content-type");
res.header("Access-Control-Allow-Methods", "PUT,POST,GET,DELETE,OPTIONS");
res.header("X-Powered-By", ' 3.2.1')
res.header("Content-Type", "application/json;charset=utf-8");
if(req.method == "OPTIONS") {
res.send("200");
} else {
next();
}
});
// development only
if('development' == app.get('env')) {
app.use(express.errorHandler());
}
app.get('/', books.list);
//获得所有的图书列表
app.get('/books', books.list);
//最大的编号
app.get('/books/maxid', books.getMax);
//添加
app.post('/books/book', books.add);
//删除
app.delete('/books/id/:id', books.del);
//更新
app.put('/books/book', books.update);
http.createServer(app).listen(app.get('port'), function() {
console.log('Express server listening on port ' + app.get('port'));
});查询所有：
其它服务的测试可以使用Fiddler完成。
六、使用AngularJS调用后台服务
这里的UI使用BootStrap完成，前端使用AngularJS调用NodeJS发布的服务，将数据存放在MongoDB中。
index.js页面如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>天狗书店</title>
<link rel="shortcut icon" href="favicon.ico" />
<link rel="bookmark" href="favicon.ico" />
<link rel="stylesheet" type="text/css" href="js/bootstrap/dist/css/bootstrap.min.css" />
<style type="text/css">

}
.addBook {
padding-top: 10px;
}
.w100 {
width: 50px
}
.w200 {
width: 200px;
}
.w300 {
width: 300px
}
</style>
