Using the colon shorthand syntax makes Vue templates more concise and readable by replacing verbose v-bind directives with a simple colon prefix.
As the creator of CoreUI, a widely used open-source UI library, I’ve used shorthand syntax extensively in Vue components over 25 years of development.
From my expertise, the most effective approach is consistently using the : shorthand for all attribute binding to maintain clean, readable templates.
This creates more professional-looking code that’s easier to scan and understand.
Use : as shorthand for v-bind to bind data to HTML attributes cleanly.
<template>
<img :src="imageUrl" :alt="imageAlt" :class="imageClass">
<button :disabled="isLoading" @click="handleClick">Submit</button>
</template>
Here :src is shorthand for v-bind:src, :alt for v-bind:alt, and so on. The colon prefix tells Vue to treat the attribute value as a JavaScript expression rather than a static string. This syntax is more concise and widely adopted in the Vue community, making code more readable and maintainable.
Best Practice Note:
This is the same shorthand syntax we use consistently throughout CoreUI Vue components for clean, professional templates.
Always use the shorthand syntax for dynamic attributes and reserve the full v-bind syntax only when you need to make the binding explicit for documentation or teaching purposes.
