npm-config2env-datatypes-demo

When your npm script gets npm-config data via environment variables, how are certain data types and key names converted?

Let's test it! The script in this package just dumps the relevant parts of its environment, for input see package.json.

• Pro tip: To test any package config without special preparation (albeit less pretty), just run npm run env.
  • If a package defines its own env script, that is a special preparation. Use at own risk.

Example

$ node-version
Node.js v5.7.1, npm v3.6.0, Ubuntu 14.04.4 LTS trusty
$ npm start
                       …0 = str "zero"
                     …123 = str "positive"
            …MiXedCaseKey = str "I'm a MiXedCaseKey!"
                       …_ = str "nbsp"
                    …_123 = str "negative"
                   …arr_0 = str "2"
                   …arr_1 = str "5"
                 …arr_2_0 = str "sub"
                 …arr_2_1 = str "array"
                   …arr_3 = str "9"
               …conflict_ = str "plus wins! (this time)"
                   …false = str "false"
                   …float = str "-3.1415"
                     …int = str "-123"
      …key__w__brackets__ = str ""
     …key_h_backslashes__ = str ""
         …key_w__dashes__ = str ""
        …key_w__dollars__ = str ""
           …key_w__dots__ = str ""
        …key_w__slashes__ = str ""
         …key_w__spaces__ = str ""
    …key_w__underscores__ = str ""
            …mixedcasekey = str "doesn't conflict with MiXedCaseKey"
                    …null = str "null"
                 …obj_cat = str "meow"
                 …obj_dog = str "woof"
                …snow_man = str "snow☃man"
                     …str = str "supported"
                    …true = str "true"
