Discussion on: Environment Variables in Next.js

[Eric Wallen]

Hi, I am having the same problem. This solution is working locally for development but when I deploy to preview or production the values are undefined.

Thanks for helping me get this far. It's nice to have a development working. If you have any idea how to get preview and production to work I would be truly in your debt.

A workaround I found for now is to list all the variables you want in the client side code in the env property of the Next.js config.

env: {
    AUTH_SECRET: process.env.AUTH_SECRET,
}

I updated the post with more details.

Sweet, thanks. I tried it and it's working. Very helpful.
