Can anyone help me figure out how to incorporate this awesome animation from CodePen (link here: https://codepen.io/iprodev/pen/azpWBr) into a Vue project?
I've tried implementing it like so:
<template>
<div>
<canvas height="100" id="confetti" width="100"></canvas>
</div>
</template>
<script>
export default {
created () {
// Insert JS code from the CodePen link here
}
}
</script>
Absolutely feasible! There are some steps you should take to make it happen. The code within the Codepen snippet is enclosed in a DOMContentLoaded event handler, as you need access to the actual DOM tree. In Vue applications, this event cannot be used because they are single-page applications and the loaded event is triggered long before your view is rendered.
In this scenario, opt for the mounted event instead of the created component lifecycle event. By using mounted, you ensure that the component's DOM is truly attached to the main document.
Additionally, you will require access to the actual HTMLCanvasElement. Instead of finding it by ID, construct your Vue.js $refs like this:
<canvas ref="confetti" height="100" width="100"></canvas>
Within your component, you can then reference the DOM element as:
mounted() {
this.$refs.confetti // Reference to HTMLCanvasElement
}
This method eliminates the need for global id attributes with Vue.js. The remaining code involves organizing it within your component as desired. You might consider encapsulating canvas rendering logic into a separate module and either pass the Canvas element or integrate the methods into the Vue instance.
Lastly, there are several event handlers assigned to the window object such as resize. It is crucial to properly clean them up when the component is being destroyed. Neglecting this step means these events will continue triggering handlers even after the destruction of the component. To address this, utilize the beforeDestroy lifecycle event provided by Vue to tidy up all globally registered event handlers.
