NodeJS : How to save a rendered view as a static .html file?

Question

i'm using NodeJS for a school project and I have to generate a dynamic html page with Express and swig variables. But here comes the problem: I have to save the rendered view with the variables replaced by their content as a static .html file.

I tried to read the documentation about FS but I found nothing about taking a whole html page and put the html code inside a file. The only way I found was to "Right-click" and "save as" but that's not how I'm supposed to do it.

Any ideas or suggestions for how to do this?

If you are using swig templating engine then we need to get the output of the Swig template first:

var swig  = require('swig');
var template = swig.compileFile('/path/to/your/template.html');
var output = template({
    foo: 'bar'
});

Now that you have the output, we can use fs to save the html:

var fs = require('fs');
fs.writeFile("/path/to/destination.html", output, function(err) {
    if(err) {
        return console.log(err);
    }

    console.log("The file was saved!");
}); 

Side note: Swig is NOT MAINTAINED anymore and has got security holes.
