使用默认文件中的策略覆盖 YAML 中的设置？

Question

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

config/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，将默认值保留在 config/default.yml 中，并在类似于以下内容的覆盖文件中选择不同的策略（上述 experienceStrategies: 之一）覆盖它们:

experience: *webDevExperience

config/override.yml

并希望产生以下结果：

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

...

但是，我没有使用 node-config 库，而是遇到了错误；有没有办法在 yaml 和 node.js 中使用其他库或坚持使用节点配置来做到这一点？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.

使用 node-config-yml 库实际上达到了目的，尽管它在这方面的文档很少，但它工作得很好。

看来是将两者的配置在内存中做成了一个文件。您可以使用别名和 node-config 中的合并功能，并根据需要覆盖。
