The following code sets up a simple HTTP server with Express.js.Ĭonsole.log(`Server started at port $`) It will be created after the author and license fields are over. If you want some other name, like app.js, you can do the naming here. Now there is one field called entry point where you can give a name to your main file (. Inside /node-project, we will create the package.json file for our Node.js + Express.js application typing the below command.įill the name, version, description and other such fields with your own values. “Developing template engines for Express”.ĭocumentation translations provided by StrongLoop/IBM:įrench, German, Spanish, Italian, Japanese, Russian, Chinese, Traditional Chinese, Korean, Portuguese.Ĭommunity translation available for: Slovak, Ukrainian, Uzbek, Turkish and Thai.Create a working directory for your project, say, /node-project. To learn more about how template engines work in Express, see: The view is still re-rendered with every request even when the cache is on. Note: The view engine cache does not cache the contents of the template’s output, only the underlying template itself. When you make a request to the home page, the index.pug file will be rendered as HTML. The syntax of pug makes it a very clean and effective. We can say that pug is the middleman who plays a role to convert the injected data and translate it into html syntax. You must specify the extension of the view file. Pug in node.js is a template engine that uses case sensitive syntax to generate html, in other words it returns a string of html rendered as per data specified in a pug file. Then create a route to render the index.pug file. app.set('view engine', 'pug')Ĭreate a Pug template file named index.pug in the views directory, with the following content: html Library follows this convention by mapping all of the popular Node.js template engines, and therefore works seamlessly within Express.Īfter the view engine is set, you don’t have to specify the engine or load the template engine module in your app Įxpress loads the module internally, as shown below (for the above example). Some template engines do not follow this convention. Which is called by the res.render() function to render the template code. Express-compliant template engines such as Jade and Pug export a function named _express(filePath, options, callback),
