Organize Development and Production files in npm or webpack for improved efficiency

In React Native projects, we typically use index.android.js and index.ios.js to differentiate between the same file for Android and iOS platforms.

But I wonder if it's possible to separate files based on the development and production environments as well. Could a tool like webpack, a plugin, or even node allow us to have files like index.develop.js and index.js (for production) and then require them using something like require('index')?

Answer №1

Absolutely! By utilizing process.env.NODE_ENV, you have the ability to dynamically load modules using require():

  const selectedModule = process.env.NODE_ENV === "production"
    ? require("./production")
     : require("./development");

When production mode is active, the comparison will be optimized inline and the require("./development") call will be eliminated for enhanced performance.
