To better understand how template engines work in Express, read “Developing template engines for Express”. On making a request to the home page, “index.pug” will be rendered as HTML. If the view engine property is not set, you will have to specify the extension of the view file, else you can omit it. Then create a route to render the “index.pug” file. Once the view engine is set, you don’t have to explicitly specify the engine or load the template engine module in your app, Express loads it internally as shown below, for the example above.Ĭreate a Pug template files named “index.pug” in the views directory, with the following content.
Some template engines do not follow this convention, the Consolidate.js library was created to map all of node’s popular template engines to follow this convention, thus allowing them to work seamlessly within Express. We’ve also seen how we can modify this application to suit our needs.Īs we saw the express-generator package is a utility that provides a command-line tool you can use to scaffold your project - like creating boilerplate folder structure, files, and code.Express-compliant template engines such as Pug, export a function named _express(filePath, options, callback), which is called by res.render() to render the template code. We generated a project structure and started our application on the server and displayed an ouput.
In this tutorial, we’ve discussed how to generate an Node.js-express application using the express generator. You’ll notice that you just modified the routes and any other feature on the Express generated application as a normal Node.js initialised app. we directing the application of which pages to useĪpp.
you can also set views of your choice here.Īpp. the following lines are used to setup view templates for our application these packages are used to parse cookie valuesĬonst cookieParser = require( 'cookie-parser')
use middleware to serve static files app.use (express.static ('public')) The above code can also be used to create a virtual path along with setting public directory for project. By default, the view helper paginate.href is already executed with the inherited req variable. To do this, first of all we will create a folder or directory named public in our project directory then add the following line of code in our index.js.
as the href in Prev or Next ).these packages will aid in application routingĬonst homePageRouter = require( './routes/home') Ĭonst studentEngineeringRouter = require( './routes/engineering-education') paginate.href (req) When you use the paginate middleware, it injects a view helper function called paginate.href as, which you can use in your views for paginated hyperlinks (e.g. Var createError = require( 'http-errors') Let’s start by creating an express application using Express generator.
In this section, we will look at the Express generator package, how it’s installed and used to generate folder structure. Then create a further directory called html and a. Create a new directory named pug-examples and change into it.
The Express-generator package is a utility that provides a command-line tool you can use to scaffold your project - ie create boilerplate folder structure, files and code. In this tutorial, we’ll be discussing the concepts of the Node.js Express generator tool.
