There are multiple ways to pre-load images on a Vue.js project. Here are two common methods:
- Using the image HTML element:
In your Vue file, add an img element for each image you want to pre-load.
Set the src attribute of each img element to the URL of the image.
You can hide these images by setting their CSS property display to none.
This will make the browser load the images in the background so they will be cached when you actually display them.
- Using the new Image() object:
In your Vue component's mounted hook, create a new Image object for each image you want to pre-load.
Set the src property of each Image object to the URL of the image.
You can store these Image objects in an array or any data structure you prefer.
This will also load the images in the background and cache them.
Note that some browsers may have limitations on the number of concurrent image loads, so it's recommended to load only a reasonable number of images at a time to avoid performance issues.
Once the images are pre-loaded, you can then display them whenever needed in your Vue template or component.
