【Nodejs&&ExpressJS&&AngularJS】安装与框架搭建

npm install -g express
npm install -g express-generator
npm install -g yo

npm install -g generator-angular

npm install -g bower

npm install -g nodemon

cd $PROJECT_HOME
mkdir client
cd client

yo angular

vi client/Gruntfile.js

修改dist: ‘dist‘with dist: ‘../server/dist‘.

grunt serve

cd $PROJECT_HOME
mkdir server

express

npm install

mkdir dist

delete public views 文件夹

vi app.js 

 注释掉如下行：

app.set(‘views‘, path.join(__dirname, ‘views‘));
app.set(‘view engine‘, ‘jade’);
app.use(express.static(path.join(__dirname, ‘public‘)));
app.use(‘/‘, routes);
app.use(‘/users‘, users);

添加如下行

/**

 */
if (app.get(‘env‘) === ‘development‘) {
    // This will change in production since we‘ll be using the dist folder
    app.use(express.static(path.join(__dirname, ‘../client‘)));
    // This covers serving up the index page
    app.use(express.static(path.join(__dirname, ‘../client/.tmp‘)));
    app.use(express.static(path.join(__dirname, ‘../client/app‘)));

    // Error Handling
    app.use(function(err, req, res, next) {
        res.status(err.status || 500);
        res.render(‘error‘, {
            message: err.message,
            error: err
        });
    });
}

/**
 * Production Settings
 */
if (app.get(‘env‘) === ‘production‘) {

    // changes it to use the optimized version for production
    app.use(express.static(path.join(__dirname, ‘/dist‘)));

    // production error handler
    // no stacktraces leaked to user
    app.use(function(err, req, res, next) {
        res.status(err.status || 500);

        });
    });
}
