Steps to use components in vue

The steps for using components in Vue are: Create a component, define a component template, define a component script, register a component, use the component in the template to pass props (optional), emit events (optional), use slots (optional)

Steps to use components in Vue

Step one: Create components

• Use Vue CLI scaffolding to create a new component:vue create component-name
• Or manually create a component file (.vue extension) in the src directory

Step 2: Define the component template

• Add the template code in the component file and specify the HTML structure for component rendering.

Step 3: Define component script

• Add script code in the component file to define the function and status of the component.
• Includes data(), methods(), computed() and other hook functions.

Step 4: Register the component

• Use the Vue.component() method to register the component in the main.js file.
• Specify the component name and options object (including templates and scripts).

Step 5: Use the component in the template

• In the main template file, use the component name as a custom HTML element using the component.
• For example:

##Step 6: Pass props (optional)

Components can receive props (properties) for passing data from parent components.
• Define the props() option in the component script and pass data through the props object.

Step 7: Emit events (optional)

Components can emit events to communicate with parent components.
• Use the $emit() method in the component script to emit events, and use the v-on directive in the parent component to listen for events.

Step 8: Use slots (optional)

Components can define slots to allow sub-components to fill specific content areas.
• Use the element in the component template to define the slot.
