    TW Elements Express integration

    This article shows you how to integrate Express application with TW Elements. Free download, open source license.


    Prerequisites

    Before starting the project make sure to install the following utilities:

    • Node LTS (18.x.x or higher recommended)
    • Code editor. We recommend VSCode

    Creating a new Express application

    Let's create a fresh Express application so that we can go through all the steps together.

    Step 1

    Create new project.

    • Terminal
            
                
        mkdir my-project
        cd my-project
        npm init -y
        
            
        

    Step 2

    Install Express.

    • Terminal
            
                
        npm install express
        
            
        

    Step 3

    Install EJS. Depending on your requirements, you can choose other template engines. However, for this tutorial, we will be using EJS.

    • Terminal
            
                
        npm install ejs
        
            
        

    Step 4

    Create a folder named views in the root directory and add an index.ejs file inside with a classic HTML structure.

    Additionally, create a public folder, then within it, create a css folder and add an input.css file - add your own css styles there. Attach a link to this file in the head section.

    • ./views/index.ejs
            
                
        <!DOCTYPE html>
        <html lang="en">
          <head>
            <meta charset="UTF-8" />
            <meta name="viewport" content="width=device-width, initial-scale=1.0" />
            <link href="/css/input.css" rel="stylesheet" />
            <title>TWE Express Integration tutorial</title>
          </head>
          <body>
            <main>
              <h1>Express application</h1>
            </main>
          </body>
        </html>
        
            
        

    Step 5

    In the root directory create app.js file where will be located your Express configuration.

    • app.js
            
                
        const express = require("express");
        const app = express();
        const port = 3000;
        
        app.set("view engine", "ejs");
        app.use(express.static("public"));
        
        app.get("/", (req, res) => {
          res.render("index");
        });
        
        app.listen(port, () => {
          console.log(`Example app listening on port ${port}`);
        });
        
        
            
        

    Step 6

    To see if everything works, run the following command in the terminal:

    • Terminal
            
                
        node app.js
        
            
        

    Installing and configuring Tailwind CSS and TW Elements

    Step 1

    Install Tailwind CSS.

    • Terminal
            
                
        npm install -D tailwindcss postcss autoprefixer
        npx tailwindcss init -p
        
            
        

    File structure

    If you have followed all instructions mentioned earlier, your file structure should look like this:

          
            my-project/
            ├── node_modules/
            ├── public/        
            │   └── css/ 
            |   |   └── input.css
            ├── views/   
            │   └── index.ejs
            ├── app.js 
            ├── package-lock.json
            ├── package.json
            ├── postcss.config.js
            └── tailwind.config.js
          
        

    Step 2

    Add the paths to all of your template files in your tailwind.config.js file.

    • tailwind.config.js
            
                
        /** @type {import('tailwindcss').Config} */
        module.exports = {
          content: [
            "./public/**/*.{js,css}",
            "./views/**/*.ejs",
            "./node_modules/tw-elements/js/**/*.js",
          ],
          darkMode: "class",
          plugins: [require("tw-elements/plugin.cjs")],
        };
        
            
        

    Step 3

    Replace your own styles in input.css file with Tailwind directives.

    • ./public/css/input.css
            
                
        @import url("https://fonts.googleapis.com/css?family=Roboto:300,400,500,700,900&display=swap");
        @tailwind base;
        
        @layer base {
          html {
            @apply text-surface;
            @apply bg-white;
          }
          html.dark {
            @apply text-neutral-50;
            @apply bg-body-dark;
          }
        }
        
        @tailwind components;
        @tailwind utilities;
        
        p {
          @apply leading-[1.6];
        }           
        
            
        

    Step 4

    Install TW Elements.

    • Terminal
            
                
        npm install tw-elements
        
            
        

    Step 5

    Update the app.js file to enable serving static files from the node_modules directory.

    • app.js
            
                
        ...
        app.use(express.static("public"));
        app.use(express.static("node_modules"));
        ...
        
            
        

    Step 6

    In the head section of the index.ejs file, substitute the href attribute from input.css to the Tailwind CSS file named output.css, which will be generated during the Tailwind CLI build process. Furthermore, add a link to the TW Elements JS at the end of the body tag.

    • ./views/index.ejs
            
                
        ...
        <head>
          ...
          <link href="/css/output.css" rel="stylesheet" />
          ...
        </head>
        <body>
          ...
          <script
            src="/tw-elements/dist/js/tw-elements.umd.min.js"
            type="text/javascript"></script>
        </body>
        ...
        
            
        

    Step 7

    Add the TWE components you intend to use in your project.

    • ./views/index.ejs
            
                
        ...
        <main>
          <div class="mt-16 flex justify-center">
            <p class="text-lg">
              Hover the link to see the
              <a
                href="#"
                class="text-primary transition duration-150 ease-in-out hover:text-primary-600 focus:text-primary-600 active:text-primary-700 dark:text-primary-400 dark:hover:text-primary-500 dark:focus:text-primary-500 dark:active:text-primary-600"
                data-twe-toggle="tooltip"
                title="Hi! I'm tooltip"
                >tooltip</a
              >
            </p>
          </div>
        </main>
        ...
        
            
        

    Step 8

    Start the Tailwind CLI build process. Run the CLI tool to scan your template files for classes and build your CSS.

    • Terminal
            
                
        npx tailwindcss -i ./public/css/input.css -o ./public/css/output.css --watch
        
            
        

    And run the local server. Awesome! You're all set to dive into using TW Elements for your Express project. Have fun!

    • Terminal
            
                
        node app.js
