Reference

There is a single exported function named merge. This function will look at process.env and add settings into the passed in environment object.

merge

/*

• merge:
• @env: The config environment object to merge the environment variables into.
• @prefix: (optional) A prefix that the environment variables must have to be

•      added, which will be stripped from the key in @env.

• Runs through the environment variables for the process and adds them to @env
• if the optional prefix matches. All values will be coerced via JSON.parse,
• so they should be the correct type.
• For the following examples, assume the environment has the following
• variables set:
• foo=bar
• app.foo=baz
• You can call merge with no prefix which will add everything in the
• environment:

• let settings = {};

• env12.merge(settings);

• console.log(JSON.stringify(settings));

• {"foo": "bar", "app.foo": "baz"}
• You can also use a prefix to properly namespace your options. Note that the
• value returned is from APP_FOO and not FOO as FOO was ignored because it is
• not prefixed.

• let settings = {};

• env12.merge(settings, prefix="app");

• console.log(JSON.stringify(settings));

• {"app": "baz"} */
