To send an HTML file with Express, you can use the res.sendFile() method. This method takes the path of the file as its argument and sends it to the client.
Example:
app.get('/', (req, res) => {
res.sendFile(__dirname + '/index.html');
});
1. app.get ('/', (req, res) => {
// Wannan layin yana bayyana mai sarrafa hanya don tushen hanyar aikace-aikacen. Lokacin da aka yi buƙatu zuwa tushen hanyar, wannan aikin dawo da kira za a aiwatar da shi tare da req kuma ya sa abubuwa azaman hujjarsa.
