How to store Configuration file and read it using React

With webpack you can put env-specific config into the externals field in webpack.config.js

externals: {
  'Config': JSON.stringify(process.env.NODE_ENV === 'production' ? {
    serverUrl: "https://myserver.com"
  } : {
    serverUrl: "http://localhost:8090"
  })
}

If you want to store the configs in a separate JSON file, that’s possible too, you can require that file and assign to Config:

externals: {
  'Config': JSON.stringify(process.env.NODE_ENV === 'production' ? require('./config.prod.json') : require('./config.dev.json'))
}

Then in your modules, you can use the config:

var Config = require('Config')
fetchData(Config.serverUrl + '/Enterprises/...')

For React:

import Config from 'Config';
axios.get(this.app_url, {
        'headers': Config.headers
        }).then(...);

Not sure if it covers your use case but it’s been working pretty well for us.
