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.
