Tips for integrating Vue code into the <code> tag within Vue applications

I am venturing into creating my first npm package and am currently working on the package's demo. I want to showcase an example of how to use the component.

However, when I include the component usage within the pre and code tags as shown below:

I encounter the following error:

Templates should only be responsible for mapping the state to the UI. Avoid placing tags with side-effects in your templates, such as <style>, as they will not be parsed.

Below is the code snippet from my App.vue file:

<template>
<pre>
    <code>
        <template>
            <vlider
            :id="'first'"
            :vlider-data="slider"
            :theme="'theme-dark'"
            v-model="inputRange"
            @click="vliderClick()"
            >
                <template> slot="bullet" slot-scope="bullet"
                    <label>{{ bullet.data.label }}</label>
                    <i
                    class="em"
                    :class="[`em-${bullet.data.extras.icon}`]"
                    ></i> 
                    <a target="_blank" :href="bullet.data.extras.learnMore">Learn more ?</a>
                </template>
            </vlider>
        </template>
        <script>
            import Vlider from "vlider";

            export default {
                name: "app",
                components: {
                    Vlider
                },
                data() {
                    return {
                        inputRange: null,
                        slider: [
                            {label: "Angry", color: "#ffc300", extras: { icon: 'angry', learnMore: 'http://localhost/'}},
                            {label: "Expressionless", color: "#ffb0fe", extras: { icon: 'expressionless', learnMore: 'http://localhost/'}},
                            {label: "Astonished", color: "#ff6bd6", extras: { icon: 'astonished', learnMore: 'http://localhost/'}},
                            {label: "Confounded", color: "#ff9d76", extras: { icon: 'confounded', learnMore: 'http://localhost/'}},
                            {label: "Okay?", color: "#51eaea", extras: { icon: 'face_with_raised_eyebrow', learnMore: 'http://localhost/'}},
                            {label: "Blush", color: "#fb3569", extras: { icon: 'blush', learnMore: 'http://localhost/'}}
                        ]
                    };
                },
                watch: {
                    inputRange() {
                        console.log(this.inputRange)
                    }
                },
                methods: {
                    vliderClick() {
                        console.log(`clicked`)
                    }
                }
            };
        </script>
        <style>
            import "vlider/src/sass/vlider.scss"
        </style>
    </code>
</pre>
</template>

<script>
import Vlider from "vlider";
...
</script>

I am hopeful that it will function similarly to a normal tag in HTML. I have attempted to use various code block npm packages, but unfortunately, none have produced the desired outcome. Your suggestions and assistance would be greatly appreciated. Thank you for your help.

Answer №1

The directive called v-pre in Vue is designed to instruct Vue not to compile a specific part of the template. However, even with this directive, Vue still seems to generate warnings if the contents include certain elements like a <script> tag. The directive doesn't display the contents as raw HTML. To work around this, it's recommended to extract the content into a data variable and avoid using v-html (as it has the opposite effect).

Storing large HTML blocks within a data variable can be a bit cumbersome and may require escaping special characters such as ${...} and the </script> tag, as shown in the example. An alternative approach for better maintainability could be importing the HTML string via ajax or using a webpack import instead of directly embedding it inside the data() function.

If syntax coloring is desired for code samples, tools like vue-highlightjs may be worth considering. These tools also rely on having the source code stored in a component data variable rather than directly within the template itself.

Alternatively

For a simpler approach, pre-escape the HTML content and insert it directly into the template. Use v-pre to instruct Vue to ignore any mustache symbols within the embedded HTML:

new Vue({
  el: '#app'
});

<script src="https://unpkg.com/vue@latest/dist/vue.js"></script>
<div id="app">

  <pre><code v-pre>&lt;script&gt;... {{foo}} &lt;/script&gt;</code></pre>

</div>

member v-html [documentation][1] and make sure to use \ at the end of each line to continue the string and treating '' as text context using \'

therefore, it should look like this:

    <div v-html="example">
     <pre>
      ...
     </pre>    
    </div>

or

<div>
  {{example}}
</div>

and example should be defined inside data() [1]: https://v2.vuejs.org/v2/guide/syntax.html?#Raw-HTML

If you want to showcase code snippets on your website, consider using VueCodeBlock. This tool allows you to display code with customizable themes for both light and dark modes.

 <template>
    <VCodeBlock
      :code="code"
      highlightjs
      lang="javascript"
      theme="neon-bunny"
    />
 </template>
 <script setup>
   const code = ref(`const text = 'hello'`)
 </script>

To resolve this issue, I utilized a helpful website to encode my code. You can find the encoding tool here:

After encoding my code, I stored the encoded version in a variable and passed it to v-html. Vue then treated it as a string and displayed it accordingly.

<pre>
  <code v-html="yourCodeVariable">
  </code>
</pre>
...
<script>
...
data() {
  return {
     yourCodeVariable: `your encoded html code here`
  }
}
...
