Whenever you are building any project or product for your startup using React, obviously you don't want to make your source code visible to customers or clients.

I have been working on React for quite some time now and I have seen many times that the source code is clearly visible in the Developers Tools, This is a common mistake which I have seen very frequently.

So If you are building your project using React & using the create-react-app boilerplate to get started. You need to do one thing to hide your source code from the developer's section, just update this in your package.json file.

"build": "GENERATE_SOURCEMAP=false react-scripts build"

Voilà, Now your source code is hidden*
