How do you handle boolean and numeric .env variables using dotenv?

[ajcastro]

I saw from the docs that the latest recommended dotenv plugin as show in example is https://github.com/motdotla/dotenv, but when I tried it, it doesn't support boolean and numeric values.

I reported an issue in their repo, motdotla/dotenv#544.

How do you handle boolean and numeric .env variables?

env variables always returns strings, you can do some checking ie. process.env.IS_BOOL && process.env.IS_BOOL === 'true' etc.. or use some parser library such as https://www.npmjs.com/package/dotenv-parse-variables.

I see. So that's how they do it in javascript land. I came from Laravel/PHP where .env are automatically parsed by default.
Thanks for the tip @metalsadman !
