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

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'

现在我要做的是，保留config/default.yml中的默认值并覆盖它们在覆盖文件中选择不同的策略（上面的experienceStrategies:之一），类似于以下内容：

experience: *webDevExperience

配置/ override.yml

希望产生以下结果：

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

...

但是，使用node-config库我最终会出错;有没有办法在yaml和node.js中使用其他一些库或坚持使用node-config？我已经看到另一个名为node-config-yaml的库允许您包含其他yaml文件，但不确定是否允许您以node-config的方式覆盖设置。

/home/leeand00/Documents/lifehacker organized/docs/projdir/node_modules/config/lib/config.js:933
    throw new Error("Cannot parse config file: '" + fullFilename + "': " + e3);
    ^

使用node-config-yml库实际上做了这个伎俩，尽管它在这个问题上的文档很少，但它完美无缺。

它似乎将配置分别放在内存中的一个文件中。您可以使用别名和node-config中的合并功能，并根据需要进行覆盖。

使用默认文件中的策略覆盖YAML中的设置？
