How to implement a progress tracker in Vue.js

Implementing a progress tracker in Vue.js involves creating a component that displays the progress of a multi-step process. Here's a simple example to get you started:

1. Create a new Vue component:

   htmlCopy code
   <!-- ProgressTracker.vue -->
   <template>
     <div class="progress-tracker">
       <div v-for="(step, index) in steps" :key="index" :class="{ 'completed': index < currentStep }">
         {{ step }}
       </div>
     </div>
   </template>
   
   <script>
   export default {
     props: {
       steps: {
         type: Array,
         required: true,
       },
       currentStep: {
         type: Number,
         required: true,
       },
     },
   };
   </script>
   
   <style scoped>
   .progress-tracker {
     display: flex;
     justify-content: space-between;
     margin-bottom: 20px;
   }
   
   .progress-tracker div {
     flex: 1;
     text-align: center;
     padding: 10px;
     background-color: #e0e0e0;
     border-radius: 5px;
   }
   
   .progress-tracker div.completed {
     background-color: #4caf50; /* Green */
     color: white;
   }
   </style>
   

   This component accepts two props: steps (an array of strings representing each step) and currentStep (the current step in the process).

2. Use the ProgressTracker component in your parent component:

   htmlCopy code
   <!-- App.vue -->
   <template>
     <div id="app">
       <progress-tracker :steps="steps" :currentStep="currentStep" />
       <!-- Your other content goes here -->
     </div>
   </template>
   
   <script>
   import ProgressTracker from "./components/ProgressTracker.vue";
   
   export default {
     components: {
       ProgressTracker,
     },
     data() {
       return {
         steps: ["Step 1", "Step 2", "Step 3", "Step 4"],
         currentStep: 2, // Set the current step dynamically based on your application state
       };
     },
   };
   </script>
   
   <style>
   #app {
     font-family: Avenir, Helvetica, Arial, sans-serif;
     text-align: center;
     color: #2c3e50;
     margin-top: 60px;
   }
   </style>
   

   This is a basic example, and you may need to customize it based on your specific requirements. Adjust the styling and structure as needed for your application.

3. Run your Vue.js application: Make sure you have Vue CLI installed. If not, you can install it using npm install -g @vue/cli. Then, run your application with npm run serve.

Now, when you update the currentStep in your parent component, the progress tracker will visually show the completed steps.
