VueJS - Template Syntax

Using VueJS Template Syntax

VueJS provides a powerful and flexible template syntax for binding data to the DOM. This guide covers the basics of VueJS template syntax, including interpolation, directives, and dynamic attributes.

Interpolation

Text Interpolation

Use double curly braces {{ }} to bind data to the template and display it as text:

  
{{ message }}




                

Raw HTML

Use the v-html directive to output raw HTML:

Directives

v-bind

The v-bind directive dynamically binds one or more attributes, or a component prop, to an expression:

v-if

The v-if directive conditionally renders an element based on the truthiness of an expression:

  
This text is visible




                

v-for

The v-for directive renders a list of items by iterating over an array:

  

    
{{ item.text }}
  




                

v-model

The v-model directive creates a two-way binding on form input, textarea, and select elements:

  
  
{{ message }}




                

Event Handling

v-on

The v-on directive is used to listen to DOM events and execute methods:

  Click me




                

Dynamic Attributes

You can bind dynamic attributes using the v-bind directive:

  Click me




                

Best Practices

Follow these best practices when using VueJS template syntax:

• Keep Templates Simple: Keep your templates simple and focused. Avoid complex logic in the template.
• Use Computed Properties: Use computed properties for complex logic instead of methods to keep your templates clean and efficient.
• Avoid Inline Handlers: Avoid using inline event handlers in templates. Define methods in the Vue instance instead.
• Use Key Attribute: When using v-for, always provide a unique key attribute for better performance and maintainability.
• Organize Directives: Organize and group related directives together for better readability.

Summary

This guide provided an overview of VueJS template syntax, including interpolation, directives, event handling, and dynamic attributes. By understanding and utilizing these features, you can create dynamic and interactive user interfaces with VueJS.
