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. We passed the value 22 to the functionToPass2 () function inside the function2 () function.
We passed the functionToPass2 () function as a parameter to the function () function with the ActionHowever, manually refreshing the browser to see updates slows down your development process. We defined the function functionToPass2 (int x) which takes an integer value as a parameter, increments it with 10 and prints the result. 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. 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.
PASSING FUNCTION INTO PUG TEMPLATE INSTALL
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
PASSING FUNCTION INTO PUG TEMPLATE CODE
You'll use nodemon to monitor your project source code and automatically restart your Node.js server whenever it changes. js: touch index.js Create an npm script to run the application ?️ 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. You'll build a login portal for a restaurant named WHATABYTE using server-side rendering (SSR): Look for the ?️️ emoji if you'd like to skim through the content while focusing on the build steps.
PASSING FUNCTION INTO PUG TEMPLATE HOW TO
There may be some other ways of doing this too, so if you use some other approach, feel free to share it in the comments.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. The method style of the third approach works best especially if you need to be able to reuse the code, but it’s the most complex of them. The second is something in between, but it limits reusability. The first is most useful when you just need to get something done quickly, but it isn’t very clean. With these three approaches you can do quite a lot. This way the code is easy to reuse and maintain, as you can use the code anywhere at all because it doesn’t depend on parameters being in the URL, in a global variable or any other such hinderance. You find a list of included projects/licenses here.
The code-editors are based on 'Ace' and the backend is running 'html2pug' and 'html2jade' plugins to convert your html content to pug syntax. The main idea of this approach is that you can put your actual JS code into a separate file, and then in your page where you need the code, you include the file with a script tag and add another script tag, which sets up the object with the configuration you need. We're using 'Bootstrap' as base template using a free 'Boostwatch' template. Here’s a simple approach to extracting get parameters from the URL:įunction getQueryParameters ( ) Pug’s syntax resembles that of traditional HTML but is a lot cleaner and prioritizes indentation and spacing for controlling the flow of logic. Its function is to convert the provided data into HTML content and serve it as a static page. Since JavaScript can see the current page’s complete URL, you can create a script to manually parse the variables you want from the URL. Pug is a template engine that can be used to inject dynamic data into an HTML page. Also, it doesn’t have any built in methods for easily accessing GET data either, but it’s possible. However, due to limitations of JavaScript, you won’t be able to read POST data using it. This is an approach you are probably familiar with from server-side languages: Using GET or POST variables to pass values to scripts. Also, with very complex scripts (which are usually also the reusable kind), this does not really work so well. Because your script is written straight into the template, to reuse it elsewhere you need copypasting. However, this approach does not lend itself for reusable code. The pro’s of this approach is of course the simplicity – as long as the script itself is not very complex, this approach is very easy to use and won’t require any special JavaScript coding tricks either. The example shows a very simple function which just alerts a message with a variable’s value. You'll get an alert with a value from PHP when this page loads
