What does res.render do and what does the html file look like?
res.render()
function compiles your template (please don’t use ejs), inserts locals there, and creates html output out of those two things.
Answering Edit 2 part.
// here you set that all templates are located in `/views` directory app.set('views', __dirname + '/views'); // here you set that you're using `ejs` template engine, and the // default extension is `ejs` app.set('view engine', 'ejs'); // here you render `orders` template response.render("orders", {orders: orders_json});
So, the template path is views/
(first part) + orders
(second part) + .ejs
(third part) === views/orders.ejs
Anyway, express.js documentation is good for what it does. It is API reference, not a “how to use node.js” book.
