Component

Code Style

Zova provides a more intuitive, elegant, and powerful code style, drawing from the following core designs of Vue3, React, and Angular:

• Vue3: Intuitive state management
• React: Flexible TSX rendering
• Angular: Powerful IOC container

Creating a Component

Taking the module demo-student as an example, create a component card

1. CLI Command

$ zova :create:component card --module=demo-student

2. Menu Command

TIP

Context Menu - [Module Path]: Zova Create/Component

Enter the component name card as prompted, and the VSCode plugin will automatically create the code skeleton for the component

Controller Definition

@Controller()
class ControllerCard extends BeanControllerBase {
  protected render() {
    return null;
  }
}

Component Wrapper

Zova automatically generates a component Wrapper for each component. For example, the component card corresponds to the component Wrapper ZCard

INFO

All component Wrappers use the Z prefix, making it easy to quickly find components in JSX

Use Component

import { ZCard } from 'zova-module-demo-student';

class RenderPageCounter {
  render() {
    return (
      <ZCard></ZCard>
    );
  }
}

INFO

Based on the support of the compiler, ZCard will automatically switch to asynchronous loading mode. Specifically, the system will asynchronously load the module demo-student, then obtain the component card, and then render the component

How to Reference Component Instance

In Zova, instead of using Template Ref to reference component instance, you directly reference the component's corresponding controller, which supports more intuitive and powerful type hints

import type { ControllerCard } from 'zova-module-demo-student';
import { ZCard } from 'zova-module-demo-student';

class RenderPageCounter {
  cardRef: ControllerCard;

  render() {
    return (
      <ZCard
        controllerRef={ref => {
          this.cardRef = ref;
        }}
      ></ZCard>
    );
  }
}
