Which is called by the res.render() function to render the template code.Įxpress-compliant template engines such as Jade and Pug export a function named _express(filePath, options, callback), This article shows how you can create a 'skeleton' website using the Express Application Generator tool, which you can then populate with site-specific routes, views/templates, and database calls. Some template engines do not follow this convention. In this case, we'll use the tool to create the framework for our Local Library website, to which we'll later add all the other code needed by the site. 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).

Then create a route to render the index.pug file. Option One is having it confgured through angular and compile html with gulp.

You must specify the extension of the view file. The other option is having it rendered through Express. In last case I ran into an issue that express does not register angular ui route change hence the template is not being rendered. When you make a request to the home page, the index.pug file will be rendered as HTML. Note: The view engine cache does not cache the contents of the template’s output, only the underlying template itself. Open a separate terminal instance, and run the command below to install the pug package from NPM: npm install pug Afterward, open the server.js file in your editor, set pug as the view engine, and save the file. The view is still re-rendered with every request even when the cache is on. To learn more about how template engines work in Express, see: You dont need to require the pug package in your code after setting the view engine as Express already does so internally. “Developing template engines for Express”.
