  1. I followed the same steps, but i am getting this error: Unable to resolve “@env” from “App.tsx”

    Here is my babel.config.js:
    module.exports = function (api) {
    api.cache(true);
    return {
    presets: [“babel-preset-expo”],
    env: {
    production: {
    plugins: [“react-native-paper/babel”],
    },
    },
    plugins: [
    [
    “module:react-native-dotenv”,
    {
    envName: “APP_ENV”,
    moduleName: “@env”,
    path: “.env”,
    allowUndefined: true,
    },
    ],
    ],
    };
    };

    Not sure what is going wrong here, i tried adding a env.d.ts type declarations as well, but didn’t work. I am using react-native with Expo + typescript.

  2. Hi I’m the maintainer for react-native-dotenv. My recommendation is: only use react-native-dotenv as a devDependency
