ExtJS（5）Sencha构建不同环境的配置 [英] ExtJS (5) Sencha build configurations for different environments

问题描述

我有一个指向一个API的ExtJS 5.0应用程序。在开发中，我想使用 http：// localhost ，但在生产当然还有一些其他服务器。

在 sencha app build 中有没有办法从外面设置应用的变量？或者在代码中访问一些ENV变量？

如果有人可以帮助我会很棒。

谢谢非常多，

Sebastian

解决方案

这个，但我不知道这是最好的方法。在你的app.json中，你会发现这样一个部分：

  / ** 
 *环境特定
 *设置。 
 * / 
production：{
 banana：'no'
}，
testing：{
 banana：'yes'
}，
开发：{
 
}，
  

<显然，我已经添加了香蕉字段。我们不允许在生产中部署香蕉，所以我根据环境设置值是否。

然后在构建时，我是否做sencha应用程序构建测试或sencha应用程序构建生产，它将在相应的香蕉环境中构建环境的Ext.manifest对象。

所以在应用程序中，我可以通过以下方式访问该值：

  if（Ext.manifest.banana ===yes）
  

我假设你可以使用相同的技术来定义其他水果的领域，或者甚至与水果相关的数据。

我从本文中获得了想法：
当您启动您的应用程序，您会发现app.json的处理内容加载为Ext.manifest。

像我说的，我不知道这是否是最好的方式，但我怀疑可能是。 >

I have an ExtJS 5.0 app that points to an API. On development, I'd like to use http://localhost but on production of course some other server.

Is there a way to set an app's variable from the outside during sencha app build ? Or access some ENV variable in the code?

Would be great if anybody could help me.

Thank you very much,

Sebastian

解决方案

I found a way of doing this but I am not sure it is the best way. In your app.json you will find a section like this:

/**
 * override objects for setting build environment specific 
 * settings.
 */
"production": {
    banana : 'no'
},
"testing": {
    banana : 'yes'
},
"development": {

},

Obviously I have added the banana field myself. We are not allowed to deploy a banana in production so I set the value yes or no based on the environment.

Then at build whether I do 'sencha app build testing' or 'sencha app build production' it will build in the respective banana value for the environment into the Ext.manifest object.

So in the application I can access the value through:

if (Ext.manifest.banana === "yes")

I presume you can use the same technique to define fields for other fruit, or perhaps even non-fruit related data.

I got the idea from this document: "When you launch your application, you will find the processed content of app.json loaded as "Ext.manifest"." http://docs.sencha.com/cmd/5.x/microloader.html

Like I said I don't know if this is the best way to do it but I suspect it might be.
