1. Source protection

>  The source code of the project involves node End background code , And front end code , The source code protection measures are as follows ：
> 1: node： Code obfuscation + encryption + Compress 
> 2:  client ： What is provided to the customer is the compiled code 
> 3: node The client and the compiled client share a configuration file ; The difficulty is that the client is compiled code , When the configuration file is updated, the client cannot recognize it , Therefore, the dynamic loading method is adopted , Here are the specific steps .

Because the client and node The server involves configuration , And the client code should be sent to the client after compilation , Therefore, if the customer modifies the configuration according to his own business scenario , The compiled client code does not recognize the latest configuration file ;node Because the source code is provided , So you can get the latest configuration . In this case, the solution is as follows ：

Define a global configuration file in the root directory of the entire project config.json.

{
  "production":{
    "HOST": "https://nfs-src.sf8cloud.com"
  },
  "test":{
    "HOST": "https://test-nfs.sf8cloud.com"
  },
  "development":{
    "HOST": "https://dev-nfs.sf8cloud.com"
  }
}

node The end is direct require introduce , according to process Start the environment selection in different environments in the configuration file host Address ;
Focus on the client , How does the compiled client get the update of the configuration file ？
The following code , In fact, it is obtained dynamically through request , Of course /envInfo This request is in Node Add a EnvController.js（ The code is as follows ）, stay EnvController.js The global configuration file under the changed directory is operated in , And then according to node The client starts the environment differently and sends the configuration data of the corresponding environment to the client .

 axios.get('/envInfo').then(res => {
      console.log('======serverConfig===',res)
      Vue.prototype.ydHostConfig = res.data
      // localStorage.setItem('ydHostConfig', JSON.stringify(res.data))
    }).catch(err => {
      console.log('======err',err)
    })

/**EnvController.js**/

const configInfo = require('../../serverConfig.json')
module.exports = {
  /**
   *  Get the environment information of the server , Match the front-end environment 
   */
  getEnvInfo(req, res){
    configInfo.env = process.env.NODE_ENV
    if (process.env.NODE_ENV === 'production') {
      return res.ok(configInfo.production)
    } else if(process.env.NODE_ENV==='test'){
      return res.ok(configInfo.test)
    }else {
      return res.ok(configInfo.development)
    }
  }
}
