⛓️ Using existing middleware
We don’t always need to write our own middlewares. For common tasks, such as parsing JSON request bodies, there are existing middlewares we can re-use.
Exercise
Make a copy of your previous middleware application.
Delete the middleware you wrote that handles the JSON request POST body.
Switch to instead the JSON middleware built in to Express.
Debug why the curl command suggested in the previous exercise doesn’t work. Fix this problem by modifying the curl command.
