Proper way to set response status and JSON content in a REST API made with nodejs and express

Question

I am playing around with Nodejs and express by building a small rest API. My question is, what is the good practice/best way to set the code status, as well as the response

Answer 1

I am using this in my Express.js application:

app.get('/', function (req, res) {
    res.status(200).json({
        message: 'Welcome to the project-name api'
    });
});
