Node.js Express how do I send response as javascript or other file type

I have code that reads the file 'example.js' and sends it to the client.

app.get('/mods/example.js', function(req, res) {
    fs.readFile('./mods/example.js',
            {encoding: 'utf-8'},
            (err, data) => {
        if (!err)
        {
            res.send("var example = new Mod();" + data);
        }
    });
});

The problem is how do I send the response as a javascript file?

When I open the file in the web browser it is an html file not a javascript file.

Thanks in advance!

Solution

  • As suggested by noisypixy, I used the res.type function to change the type of the response to javascript.

    res.type('.js');
res.send("var john = new Human();");

    There are a lot of other file types such as html, json, png.
