experienceList:
  - dbAnalyst: &dbAnalyst
      posName: 'Database Analyst / Net Tech'
      companyName: 'Choices People Supporting People'
  - webDevXetex: &webDevXetex
      posName: 'Software Engineer'
      companyName: 'Xetex Business Systems'
# ...
experienceStrategies:
  - defaultExperience: &defaultExperience
    - <<: *dbAnalyst
    - <<: *webDevXetex
  - webDevExperience: &webDevExperience
    - <<: *webDevXetex
#...
experience: *defaultExperience

配置/default.yml

这导致experience在 YAML 中输出为：

experience: 
  - dbAnalyst:
      posName: 'Database Analyst / Net Tech'
      companyName: 'Choices People Supporting People'
  - webDevXetex:
      posName: 'Software Engineer'
      companyName: 'Xetex Business Systems'

现在我想做的是，保留默认值并覆盖它们，在类似于以下的覆盖文件中config/default.yml选择不同的策略（上述之一）：experienceStrategies:

experience: *webDevExperience

配置/覆盖.yml

并希望产生以下结果：

experience: 
  - webDevXetex:
      posName: 'Software Engineer'
      companyName: 'Xetex Business Systems'

但是，使用 node-config 库时，我会遇到错误；有没有办法在 yaml 和 node.js 中使用其他库或坚持使用 node-config 来做到这一点？我见过另一个名为node-config-yaml 的库，它允许您包含其他 yaml 文件，但不确定它是否允许您以使用node-config.

    throw new Error("Cannot parse config file: '" + fullFilename + "': " + e3);
    ^

使用该node-config-yml库实际上起到了作用，尽管它关于此事的文档很少，但它可以完美地工作。

似乎将配置从它们两个都放在内存中的一个文件中。您可以使用别名和合并功能，node-config并根据需要覆盖。
