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

问题描述

我有一个指向 API 的 ExtJS 5.0 应用程序.在开发上，我想使用http://localhost，但在生产当然还有其他一些服务器.

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.

有没有办法在 sencha app build 期间从外部设置应用程序的变量?或者在代码中访问一些 ENV 变量?

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?

如果有人能帮助我就好了.

Would be great if anybody could help me.

非常感谢，

推荐答案

我找到了一种方法，但我不确定这是最好的方法.在您的 app.json 中，您会找到这样的部分:

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": {

},

显然我自己添加了香蕉场.我们不允许在生产中部署香蕉，所以我根据环境设置值是或否.

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.

然后在构建时，无论我执行sencha app build testing"还是sencha app build production"，它都会将环境的相应香蕉值构建到 Ext.manifest 对象中.

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.

因此在应用程序中我可以通过以下方式访问该值:

So in the application I can access the value through:

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

我认为您可以使用相同的技术来定义其他水果的字段，甚至可能是非水果相关数据.

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

我从这个文档中得到了这个想法:当你启动你的应用程序时，你会发现 app.json 的处理内容加载为Ext.manifest"."http://docs.sencha.com/cmd/5.x/microloader.html

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

就像我说的，我不知道这是否是最好的方法，但我怀疑它可能是.

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