Getting Started with Barcode Web Component

Smart UI for Web Components is distributed as smart-webcomponents NPM package. You can also get the full download from our website with all demos from the Download page.

Setup the Barcode

Smart UI for Web Components is distributed as smart-webcomponents NPM package

Download and install the package.
```
npm install smart-webcomponents
```

Once installed, import the Barcode module in your application.

<script type="module" src="node_modules/smart-webcomponents/source/modules/smart.barcode.js"></script>

Adding CSS reference

The smart.default.css CSS file should be referenced using following code.

<link rel="stylesheet" type="text/css" href="node_modules/smart-webcomponents/source/styles/smart.default.css" />

Add the Barcode tag to your Web Page

<smart-barcode id="barcode"></smart-barcode>

Create the Barcode Component

The following code adds a simple barcode to the page.

<!DOCTYPE html>
<html lang="en">
<head>
 <link rel="stylesheet" href="../../source/styles/smart.base.css" type="text/css" />
 <script type="text/javascript" src="../../source/smart.element.js"></script>
 <script type="text/javascript" src="../../source/smart.barcode.js"></script>
</head>
<body>
 <smart-barcode type="codabar" value="A2402B"></smart-barcode>
</body>
</html>

Demo

The barcode element supports a wide range of the most common barcode types available:

PharmaCode
CodaBar
Code128A | Code128B | Code128C
MSI | MSI10 | MSI11 | MSI1010 | MSI1110
EAN8 | EAN13
Code39
Code93

<!DOCTYPE html>
    <html lang="en">
    <head>
        <link rel="stylesheet" href="../../source/styles/smart.base.css" type="text/css" />
        <script type="text/javascript" src="../../source/smart.element.js"></script>
        <script type="text/javascript" src="../../source/smart.barcode.js"></script>
    </head>
    <body>
        <smart-barcodetype="pharmacode" value="12345"></smart-barcode>
        <smart-barcode type="code128c" value="22481203"></smart-barcode>
        <smart-barcode type="codabar" value="A2402B"></smart-barcode>
        <smart-barcode type="code39" value="*1234*"></smart-barcode>
        <smart-barcode type="code128a" value="EXAMPLE"></smart-barcode>
    </body>
    </html>

Demo

Appearance

The rendering mode is set using the renderAs property - svg(default) and canvas are supported.
The recommended rendering mode is svg as the image quality remains the same as the barcode is zoomed in.

<!DOCTYPE html>
    <html lang="en">
    <head>
        <link rel="stylesheet" href="../../source/styles/smart.base.css" type="text/css" />
        <script type="text/javascript" src="../../source/smart.element.js"></script>
        <script type="text/javascript" src="../../source/smart.barcode.js"></script>
    </head>
    <body>
        <smart-barcode render-as="svg" type="codabar" value="A2402B"></smart-barcode>
        <smart-barcode render-as="canvas" type="codabar" value="A2402B"></smart-barcode>
    </body>
    </html>

Demo

The barcode's color, background color and bar dimensions can be customized by their respective properties:

<smart-barcode value="A2402B" line-color="red" line-width="3" line-height="20" background-color="lightblue"></smart-barcode>

Demo

The label of the barcode can be set to visible or hidden with displayLabel. Its color, font, size, margins and position can be customized by their respective properties. When the barcode is rendered as svg, the label can also be customized with CSS.

<smart-barcode value="A2402B" ></smart-barcode>

Behavior

Every valid barcode can be exported to a downloadable file. The export method supports the following formats:

<script>
    function exportBarcode(){
        let barcode1 = document.getElementById('export-barcode');
        barcode1.export('png', 'my-barcode');
    }
</script>
<smart-barcode id="export-barcode" value="A2402B" label-position="top" label-font-size="30" label-color="orange" label-font="arial" line-color="orange"></smart-barcode>
<button onclick="exportBarcode()">Download</button>

Demo

Smart.BarCode contains a built-in validator, which depends on the barcode type.
In the case of a invalid value, the isValid method will return false and the invalid event will be triggered.

The invalid event.detail contains multiple values that can indicate the validity of the barcode:

invalidCharacters - An array indicating the invalid characters.
patternValidity - A boolean indicating the validity of the barcode pattern.
lengthValidity - A boolean indicating the validity of the barcode length.

The demo below will output the illegal charcters of the barcode:

<!DOCTYPE html>
<html lang="en">
<head>
 <link rel="stylesheet" href="../../source/styles/smart.base.css" type="text/css" />
 <script type="text/javascript" src="../../source/smart.element.js"></script>
 <script type="text/javascript" src="../../source/smart.barcode.js"></script>
 <script>
 window.onload = function(){
    var barcode2 = document.getElementById('invalid-barcode');
    const OnInvalid = (event) => {
            let invalidChars = event.detail.invalidCharacters;
            document.getElementById("invalid-box").textContent+= invalidChars.join(' and ')
        };

    barcode2.addEventListener("invalid", OnInvalid);
}
 function changeValue(){
    barcode2 = document.getElementById('invalid-barcode');
    barcode2.value = "A1230B@!"
}
 </script>
</head>
<body>
 <smart-barcode>Click Me</smart-barcode>
</body>
</html>

Demo

Open the page in your web server.

Create, Append, Remove, Get/Set Property, Invoke Method, Bind to Event

Create a new element:

	const barcode = document.createElement('smart-barcode');

Append it to the DOM:

	document.body.appendChild(barcode);

Remove it from the DOM:

	barcode.parentNode.removeChild(barcode);

Set a property:

	barcode.propertyName = propertyValue;

Get a property value:

	const propertyValue = barcode.propertyName;

Invoke a method:

	barcode.methodName(argument1, argument2);

Add Event Listener:

	const eventHandler = (event) => {
	   // your code here.
	};

	barcode.addEventListener(eventName, eventHandler);

Remove Event Listener:

	barcode.removeEventListener(eventName, eventHandler, true);

Using with Typescript

Smart Web Components package includes TypeScript definitions which enables strongly-typed access to the Smart UI Components and their configuration.

Inside the download package, the typescript directory contains .d.ts file for each web component and a smart.elements.d.ts typescript definitions file for all web components. Copy the typescript definitions file to your project and in your TypeScript file add a reference to smart.elements.d.ts

Getting Started with Angular Barcode Component

Setup Angular Environment

Angular provides the easiest way to set angular CLI projects using Angular CLI tool.

Install the CLI application globally to your machine.

npm install -g @angular/cli

Create a new Application

ng new smart-angular-barcode

Navigate to the created project folder

cd smart-angular-barcode

Setup the Barcode

Smart UI for Angular is distributed as smart-webcomponents-angular NPM package

Download and install the package.
```
npm install smart-webcomponents-angular
```
Adding CSS reference

The following CSS file is available in ../node_modules/smart-webcomponents-angular/ package folder. This can be referenced in [src/styles.css] using following code.
```
@import 'smart-webcomponents-angular/source/styles/smart.default.css';
```
Another way to achieve the same is to edit the angular.json file and in the styles add the style.
```
"styles": [
		"node_modules/smart-webcomponents-angular/source/styles/smart.default.css"
	]
```
If you want to use Bootstrap, Fluent or other themes available in the package, you need to add them after 'smart.default.css'.

Example with Angular Standalone Components

app.component.html

 <div class="container">
    <h3>The barcode element supports a wide range of the most common barcode types available</h3>

export default App;

Running the React application

Start the app with

npm run dev

yarn run dev

and open localhost:3000 in your favorite web browser to see the output.

Setup with Vite

Vite (French word for "quick", pronounced /vit/, like "veet") is a build tool that aims to provide a faster and leaner development experience for modern web projects
With NPM:

npm create vite@latest

With Yarn:

yarn create vite

Getting Started with Vue Barcode Component

Setup Vue with Vite

In this section we will introduce how to scaffold a Vue Single Page Application on your local machine. The created project will be using a build setup based on Vite and allow us to use Vue Single-File Components (SFCs). Run the following command in your command line

npm create vue@latest

This command will install and execute create-vue, the official Vue project scaffolding tool. You will be presented with prompts for several optional features such as TypeScript and testing support:

✔ Project name: … 
✔ Add TypeScript? … No / Yes
✔ Add JSX Support? … No / Yes
✔ Add Vue Router for Single Page Application development? … No / Yes
✔ Add Pinia for state management? … No / Yes
✔ Add Vitest for Unit testing? … No / Yes
✔ Add an End-to-End Testing Solution? … No / Cypress / Playwright
✔ Add ESLint for code quality? … No / Yes
✔ Add Prettier for code formatting? … No / Yes

Scaffolding project in ./...
Done.

If you are unsure about an option, simply choose No by hitting enter for now. Once the project is created, follow the instructions to install dependencies and start the dev server:

cd 
npm install
npm install smart-webcomponents
npm run dev

Make Vue ignore custom elements defined outside of Vue (e.g., using the Web Components APIs). Otherwise, it will throw a warning about an Unknown custom element, assuming that you forgot to register a global component or misspelled a component name.

Open vite.config.js in your favorite text editor and change its contents to the following:

vite.config.js

import { fileURLToPath, URL } from 'node:url'

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    vue({
      template: {
        compilerOptions: {
          isCustomElement: tag => tag.startsWith('smart-')
        }
      }
    })
  ],
  resolve: {
    alias: {
      '@': fileURLToPath(new URL('./src', import.meta.url))
    }
  }
})

Open src/App.vue in your favorite text editor and change its contents to the following:

App.vue

<template>
  <div class="vue-root">
    <div class="container">
      <h3>The barcode element supports a wide range of the most common barcode types available</h3>
      <div>Pharmacode:</div>
      <smart-barcode id="pharma" type="pharmacode" value="1234"></smart-barcode>
      <div>Codabar:</div>
      <smart-barcode type="codabar" value="A2402B" ></smart-barcode>
      <div>Code128 A | B | C:</div>
      <smart-barcode type="code128c" value="22481203"></smart-barcode>
      <smart-barcode type="code128a" value="EXAMPLE"></smart-barcode>
      <smart-barcode type="code128b" value="example"></smart-barcode>
      <br/>
      <div>MSI 10 | 11:</div>
      <smart-barcode type="msi10" value="12345"></smart-barcode>
      <smart-barcode type="msi11" value="67890"></smart-barcode>
      <div>Code39:</div>
      <smart-barcode type="code39" value="*1234567AB*" line-width="2" ></smart-barcode>
    </div>
  </div>
</template>

<script>
import { onMounted } from "vue";
import "smart-webcomponents/source/styles/smart.default.css";
import "smart-webcomponents/source/modules/smart.barcode.js";

export default {
  name: "app",
  setup() {
    onMounted(() => {});
  }
};
</script>

We can now use the smart-barcode with Vue 3. Data binding and event handlers will just work right out of the box.

Running the Vue application

Start the app with

npm run dev

and open http://localhost:5173/ in your favorite web browser to see the output below:
When you are ready to ship your app to production, run the following:

npm run build

This will create a production-ready build of your app in the project's ./dist directory.
