我可以在构建时将参数传递给 angular-cli
我想在构建 Angular2(打字稿)应用程序时将自定义参数传递给 angular-cli.这可能吗?如何在我的代码中访问这个参数?
I would like to pass custom arguments to angular-cli when building an Angular2 (typescript) app. Is this possible? How can I access this arguments in my code?
场景是这样的:我有一个带有 2 个布局的 Angular2 应用程序.每个布局有 3 种颜色(红色、蓝色、绿色).我想建立所有可能的组合.每个布局和颜色一个应用程序 => layout1red, layout1green, layout2blue, ...
The scenario is like this: I have one Angular2 app with 2 layouts. Each layout has 3 colors (red, blue, green). I want to build all possible combinations. One app per layout and color => layout1red, layout1green, layout2blue, ...
我想为我定义布局和颜色的每个构建创建 6 个 JSON 配置文件，也许还有一些附加属性.
I want to create 6 JSON config files for each build where I define the layout and color, and maybe some additional properties.
可以使用 @angular/cli 创建多个配置文件.
It is possible to create multiple configuration files with @angular/cli.
如文档中所述自定义配置文件可以通过以下方式添加:
As mentioned in docs custom configuration files can be add in the following way:
- 创建一个
src/environments/environment.NAME.ts - 将
{ "NAME": 'src/environments/environment.NAME.ts' }添加到.angular 中的apps[0].environments对象-cli.json - 通过构建/服务命令上的
--env=NAME标志使用它们.
- create a
src/environments/environment.NAME.ts - add
{ "NAME": 'src/environments/environment.NAME.ts' }to theapps[0].environmentsobject in.angular-cli.json - use them via the
--env=NAMEflag on the build/serve commands.
因此，您可能需要 6 个用于开发的配置文件和 6 个用于生产的配置文件.
So, you would probably need 6 config files for dev and 6 config files for prod.
然后访问这些变量只需从 environment.ts 文件中导入环境对象.
And then to access those variables just import environment object from environment.ts file.
