How to make features available in development mode, while hiding them in production
Some sites/apps I work on have 2 modes. One is the development mode, the other is production, the live version.
With Next.js I find this very easy to do so by checking the value of process.env.NODE_ENV, which is set to 'development' when running it with npm run dev.
So I might have an API route that should not be public, and at the top of it, I add
if(process.env.NODE_ENV!='development')returnnull
so it does not work in production.
The same applies to a page component, which will render a blank page if accessed in production.
I use the same technique to add JSX to a component only in development mode:
