You can emulate the live reload behavior of front-end frameworks such as React and Angular in Express templates using Browsersync. Add Live Reload to Express Using Browsersync To overcome that, you'll use Browsersync. However, manually refreshing the browser to see updates slows down your development process. pug template, you can refresh the browser to see the changes. ?️ Refresh the browser to see the new page rendered on the screen. Refer to Using template engines with Express for more details. pug doesn't use title locally instead, the template it extends, layout. Pug (formerly known as Jade) is a template engine that allows you to dynamically manipulate the HTML and CSS that are ultimately rendered from the files that were written in it. json file to run nodemon and delete the test script: defines a local title variable in index. ?️ Create a dev script command in your package.
The command above is the equivalent of running npm install -save -dev nodemon. ?️ As such, install nodemon as a development dependency: npm i -D nodemon
You'll use nodemon to monitor your project source code and automatically restart your Node.js server whenever it changes. Now open the tables. pug img (src'image.png') You can run the above code using the following command : >pug tables.pug rendered tables.html. An example is given below : //Name of the file : images. js: touch index.js Create an npm script to run the application HTML Images are defined in pug with the help of img tag. ?️ Then, create the entry point of the application, a file named index. ?️ Execute the following command within the whatabyte -portal directory to initialize your Node.js project with default settings: npm init -y ?️ Create a project directory named whatabyte -portal anywhere in your system and make it your current directory: mkdir whatabyte-portal If you need to install Node.js and npm, use any of the official Node.js installers provided for your operating system. We tested this tutorial using Node.js v12. If the doctype is html, Pug knows not to mirror the attribute, and instead uses the terse style (understood by all browsers). You'll build a login portal for a restaurant named WHATABYTE using server-side rendering (SSR): If your JavaScript runtime supports ES2015 template strings (including Node.js/io.js 1.0.0 and later), you can use that syntax for attributes. For the sake of this example I’m going with 2.Empty, but the Web App starter is a pretty kick-ass starting point, albeit confusing in places and fairly opinionated. Look for the ?️️ emoji if you'd like to skim through the content while focusing on the build steps. You should be met with the following options.
In this tutorial, you'll learn how to build a simple and clean Node.js server-side rendered application using the Express framework and Pug templates styled with CSS.Īs a bonus, you'll learn how to streamline your Node.js development workflow by using nodemon to restart the server and browser -sync to reload the browser whenever relevant source files change.
