Having Trouble Implementing Canvas in My Vue.js Project

I needed to take a screenshot in my vue.js project, so I decided to use html2canvas. Here are the steps I followed to implement html2canvas:

Step 1-: Install 'html2canvas' into my project

npm install html2canvas

Step 2-: Import html2canvas into my project code.

Project Code -:

<template>
  <div class="hello">
    <div id="photo">
      <p>This is a Vue screenshot</p>
    </div>
    <button v-on:click="screenshot">Take Picture</button>
  </div>
</template>

<script>
//import html2canvas from 'vue-html2canvas';
import html2canvas from 'html2canvas';
export default {
  name: 'HelloWorld',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }
  },
  methods:{
    screenshot(){
      console.log('Function Screenshot');
    html2canvas(document.getElementById('photo')).then(canvas => {
      document.body.appendChild(canvas)
    });
    }
  }
}
</script>

However, when I run this project, it gives me the following error -:

ReferenceError: html2canvas is not defined

Any suggestions on how to solve this issue?

Answer №1

After troubleshooting, I found the solution for this issue. I removed the import statement related to 'html2canvas' and updated my function as shown below:

 updateScreenshot(){
      const html2canvas = require('html2canvas');
      console.log('Updated Screenshot Function');
      html2canvas(document.getElementById('photo')).then(function(canvas){
        document.body.appendChild(canvas)
     });
 }
