Boolean and Numeric env variables are not casted properly

[ajcastro]

I tried IS_BOOL=true but when I console.log(process.env.IS_BOOL); it displays a string "true" but it should be casted to boolean true.

I also tried IS_NUM=10 and it is a string "10" but it should be numeric 10.
I also tried IS_FLOAT=10.5 and it is a string "10.5" but it should be a float 10.5.

Environment variables are strings though, not numbers or booleans. That is true independent of this project and even of Node.js.
The function of this library is to load predefined env vars (strings) from a .env file into process.env (collection of strings).

Actually Node.js won't even let you assign any other type of value (besides a string) to a property of process.env, since that value will be converted to a string:

Refer to the other similar issues for discussion of ways to deal with casting env vars to other (not string) value types: #51 #77
There are some robust solutions offered, but the simple solution is just code that casts/parses each string according to its intended type:

const IS_BOOL = process.env.IS_BOOL === "true";
const IS_INT = parseInt(process.env.IS_INT, 10);
const IS_FLOAT = parseFloat(process.env.IS_FLOAT);

Thanks for the response. I came from Laravel/PHP where variables are parsed by default, so I thought it was the same. Someone from the quasar community answered that I can use this https://github.com/niftylettuce/dotenv-parse-variables to make it work.
