僅在帆JS生產環境（節點JS框架）

Question

我在我所製成的beforeCreate方法這樣的模型Transactions運行的函數：

beforeCreate(values,cb){ 
    //I want this code to be run in just production enviroment, not in devlopement env 
    EmailService.sendMail(values.email,values.data); 
    cb(); 
} 

在這裏，我已作出服務EmailService這將發送郵件給用戶。但我確實希望這隻能在production enviroment之內活動，而不是在發展環境中。

我不想評論這一行，因爲我有很多其他事件只能在生產環境中觸發，而不是在測試環境中觸發。這個怎麼做？

Answer 1

在應用程序代碼，您可以access the environment through the global config，像這樣：sails.config.environment。

beforeCreate(values,cb){ 
    // Production 
    if (sails.config.environment === "production") { 
     EmailService.sendMail(values.email,values.data); 
    } 
    cb(); 
} 

您的Sails.js應用程序默認在開發環境中運行。您可以在生產模式下運行setting the NODE_ENV environment variable（NODE_ENV=production node app.js）或運行sails lift --prod。

如果你願意，你還可以選擇設置環境config/local.js代替：

module.exports = { 
    /*************************************************************************** 
    * The runtime "environment" of your Sails app is either typically   * 
    * 'development' or 'production'.           * 
    *                   * 
    * In development, your Sails app will go out of its way to help you  * 
    * (for instance you will receive more descriptive error and    * 
    * debugging output)              * 
    *                   * 
    * In production, Sails configures itself (and its dependencies) to  * 
    * optimize performance. You should always put your app in production mode * 
    * before you deploy it to a server. This helps ensure that your Sails * 
    * app remains stable, performant, and scalable.       * 
    *                   * 
    * By default, Sails sets its environment using the `NODE_ENV` environment * 
    * variable. If NODE_ENV is not set, Sails will run in the    * 
    * 'development' environment.            * 
    ***************************************************************************/ 

    // environment: process.env.NODE_ENV || 'development' 
    environment: 'production' 
}

beforeCreate(values,cb){ 
    //I want this code to be run in just production enviroment, not in devlopement env 
    if (sails.config.environment === 'production') { 
    EmailService.sendMail(values.email,values.data); 
    } 
    cb(); 
}
