@vue/babel-sugar-composition-api-render-instance

Ported from luwanquan/babel-preset-vca-jsx by @luwanquan

Babel syntactic sugar for replacing this with getCurrentInstance() in Vue JSX with @vue/composition-api

Babel Compatibility Notes

• This repo is only compatible with Babel 7.x

Usage

Install the dependencies:

# for yarn:
yarn add @vue/babel-sugar-composition-api-render-instance
# for npm:
npm install @vue/babel-sugar-composition-api-render-instance --save

In your .babelrc:

{
  "plugins": ["@vue/babel-sugar-composition-api-render-instance"]
}

However it is recommended to use the configurable preset instead.

Details

This plugin automatically replaces this in setup() with getCurrentInstance(). This is required for JSX to work in @vue/composition-api as this is not available in setup()

Input:

defineComponent({ 
  setup() {
    return () => <MyComponent vModel={a.b} />
  }
})

Output (without @vue/babel-sugar-composition-api-render-instance):

defineComponent({
  setup() {
    return () => <MyComponent model={{
      value: a.b,
      callback: $$v => {
        this.$set(a, "b", $$v);
      }
    }} />
  }
})

Output (with @vue/babel-sugar-composition-api-render-instance):

import { getCurrentInstance } from "@vue/composition-api";

defineComponent({
  setup() {
    const __currentInstance = getCurrentInstance();

    return () => <MyComponent model={{
      value: a.b,
      callback: $$v => {
        __currentInstance.$set(a, "b", $$v);
      }
    }} />
  }
})
