npm start
starts the react server on the default browser, which is Firefox for me. I like Firefox for browsing but prefer Chrome in web deve
I don't like to repeatedly create a new .env file or prepend npm start every time with an additional command. You can specify your browser of choice instead of none in your shell config file. Type in your terminal the following commands:
echo export BROWSER=none >> ~/.bashrc
source ~/.bashrc
At this point you can run npm start
and be happy.
