Unlocking the power of Vue and TypeScript: Retrieving the data property in the render function

I am facing an issue while trying to implement this code in TypeScript within render method:

TS2339: Property 'options' does not exist on type 'ComponentOptions, DefaultMethods, DefaultComputed, PropsDefinition'

import Vue from 'vue'

  declare module 'vue/types/vue' {
      interface Vue {
          onSwtich: Function
      }
  }

  export default Vue.extend({
      name: 'footerTabs',
      data() {
          return {
              options: {
                  on: {
                      click: el => this.onSwtich(el)
                  }
              }
          }
      },
      render(h) {
          return h('swiper', {
              class: 'page-footer-tabs',
              attrs: {
                  options: this.options  // TS2339: Property 'options' does not exist on type 'ComponentOptions<Vue, DefaultData<Vue>, DefaultMethods<Vue>, DefaultComputed, PropsDefinition<Rec...'.
              }
          })
      },
      methods: {
          onSwtich(el): void {
              this.$emit('on-switch', el)
          }
      }
  })
  

I have attempted to add options to

interface Vue { options: object }

However, the issue persists and the code is still not functioning correctly.

Answer №1

declare module 'vue/types/options' {
    interface ComponentOptions<V extends Vue> {
        config?: any
    }
}

After further investigation, it appears this is the correct way to declare it.
