Question

I was learning Express/Node/Jade and now in the Jade file I want to include a javascript file from the public folder just for the page. For example, in jade file I type this

Well... In the first instance, it is different what happens in the browser of what happens on the server. So Jade is a rendering of HTML, therefore if you are in the browser. It's what ExpressJS shipping, ie rendering Jade. If you want to call, your HTML Javascript (Rendering of Jade), should show you where the Javascript. For exmaple

in Server.js

// Get the Javascript in the browser
app.use("/javascripts", express.static("./outJavascripts"));
// Get the URL
app.all("/", function(req, res){
  // Render the Jade and Send for the client (Browser)
  req.render("myTemplate.jade");
});

In myTemplate.jade

script(src='/javascripts/test.js')

In "./outJavascripts/test.js"

function check_test(){
    console.log("It's working! :D");
    return "It's working!";
}

If you do this, you will realize that it is run, the file "./outJavascripts/test.js" in the browser. And the function "check_test" never run in the server.
