NAME

       loose-envify - replace Node.js environment variables with plain strings

SYNOPSIS

       loose-envify <javascript_source_file.js>

DESCRIPTION

       Performs  a  Javascript  source-to-source  transformation  (transpiling), that efficiently
       replaces Node.js process.env environment variables with  plain  strings.  This  makes  the
       environment variable checks faster and easier to optimize out.

EXAMPLES

       Running this source code:

         if (process.env.NODE_ENV === "development") {
           console.log('development only')
         }

       through loose-envify:

         loose-envify index.js > bundle.js

       with NODE_ENV set to production results in:

         if ("production" === "development") {
           console.log('development only')
         }

       which, when run through a minifier, would be stripped out completely.

       However,  if you run the same script through loose-envify with NODE_ENV set to development
       it gives:

         if ("development" === "development") {
           console.log('development only')
         }

       The if statement will evaluate to true, so the code won't be removed.
