e its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enable code example

Example 1: Refused to apply style from 'http://localhost:9000/public/css/style.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

For me the solution was: instead, app.use(express.static(__dirname + '/public'));

I have used: app.use(express.static(__dirname));

now everything working correctly

Example 2: Refused to apply style from 'http://localhost:3000/css/styles.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

app.get('/style.css', function(req, res) {
  res.sendFile(__dirname + "/" + "style.css");
});
