安装strongloop框架

安装strongloop框架以及集成sequlize

install
study

1. first install node and npm

2. run npm install -g loopback-cli

3. run npm install -g apiconnect

4. run npm install -g strongloop

if you want to look version, you can run slc -v

if has error not find commond

you need run npm uninstall -g strongloop

then run npm clear cache

then run npm install -g strongloop

secusse install

1. create project run slc loopback [project name]

2. run cd [project name]

3. run npm install install nessesery package

4. install StrongLoop MySQL 连接器 npm install --save loopback-connector-mysql

5. 配置数据源

   slc loopback:datasource AccountDb

   接受默认数据源名称。对于数据库类型，选择 MySQL。

6. 创建数据模型

   slc loopback:model Account
   按照提示配置该数据模型。对于模型的“base class”，使用“PersistedModel”并选择通过 REST API 公开该模型。添加模型属性如下：
   
   Name:Account 
   Datasource:AccountDb
   Base class:PersistedModel
   Expose via REST:Yes
   Custom plural form:Leave blank
   对于数据模型上的属性，创建以下 3 个属性。
   
   Property name: email 
   Property type: string
   Required?Not required
   Property name: createdAt 
   Property type: date
   Required?Not required
   Property name: lastModifiedAt 
   Property type: date
   Required?Not required
   

7. 添加脚本来创建数据库中的模式

   在您项目的根目录下的 ./server 文件夹中创建一个 bin 目录。

   cd server

   mkdir bin

   在 server/bin 目录中，使用以下代码创建一个名为 automigrate.js 的文件。

   var app = require('../server');
   
   var accounts = [
       {
           email:'[email protected]',
           createdAt: new Date(),
           lastModifiedAt: new Date()
       },
       {
           email:'[email protected]',
           createdAt: new Date(),
           lastModifiedAt: new Date()
       }
   ];
   
   // this loads the accountDb configuration in ~/server/datasources.json
   var dataSource = app.dataSources.AccountDb;
   
   // this automigrates the Account model 
   dataSource.automigrate('Account', function(err) {
       if (err) throw err;
   
       // this loads the Account model from ~/common/models/Account.json
       var Account = app.models.Account;
       var count = accounts.length;
       accounts.forEach(function(account) {
       // insert new records into the Account table
           Account.create(account, function(err, record) {
           if (err) return console.log(err);
   
           console.log('Record created:', record);
   
           count--;
   
           if (count === 0) {
           console.log('done');
           dataSource.disconnect();
           }
           });
       });
   });
   

8. run node server/bin/automigrate.js

---

extend

1. slc loopback:property or sudo lb property add new props

2. sudo lb relation or sudo slc loopback:relation add new relation

3. sudo lb acl or sudo slc loopback:acl 定义访问权限

use sequelize orm

1. npm install --save sequelize install sequelize packge
2. npm install --save mysql2 install mysql2 packge

3. npm install --save co install co 异步控制库

4. npm install -g sequelize-auto 将数据库映射成model

5. run sequelize-auto -h localhost -d [database] -u [username] -x [password] -p 3306 -t [tablename]
