Unable to resolve module fs - react-native-dotenv-CodePudding

I am doing an online course about React-Native and Firebase but I came across an error.

Here it is : Error: Unable to resolve module fs from Documents/code/ChatApp/node_modules/react-native-dotenv/index.js:

I've seen responses that fs is not available on react-native, is that true ?

Why install a package so that in the end it can't be used?

thank you in advance for your answers

CodePudding user response：

No, fs is not available in React Native. You can use the react-native-fs package instead.

CodePudding user response：

That online course might be referring to old version of react-native-dotenv. To make it work with the new version, make these minor changes to your code as explained in this wiki. No need to install fs.

If you have a code like this

import { API_URL, API_TOKEN } from 'react-native-dotenv';

change it to

import { API_URL, API_TOKEN } from '@env';

Make sure module:react-native-dotenv is present in babel.config.js file. Example -

module.exports = {
  presets: ["module:metro-react-native-babel-preset"],
  plugins: [
    "module:react-native-dotenv",
    ...
  ]
};
