[Vue 3] Components compatibility audit

[martaradziszewska]

We need to test all components to check compatibility with the upcoming version of Vue 3.

MAIN GOALS

• create a branch with Vue CLI project and environment to test - vue3
• testing library and all components
• prepare new issues to fix

MAIN CHANGES IN VUE3

• Documentation of Vue composition API find here
  ➡️ https://vue-composition-api-rfc.netlify.com/api.html#setup

• RFC is here ➡️ https://github.com/vuejs/rfcs/tree/master/active-rfcs
  but some of the features are not implemented or changed so be careful

Want to test?

• the branch you are looking for is vue3
  the instruction ➡️ [WIP] Testing environment for Vue 3 #972
  Have some questions? Something is not working, please tell us.

OVERALL ISSUES

• mobile-observer.js - changes in Vue.observable() -> need to change to reactive
• to globally registered component we can't use Vue.component() anymore -> need to use resolveComponent or resolveDynamicComponent or another solution is required
• custom directive api change -> need to adjust focus.js, focus-trap.js, clickOutside.js
• $attrs automatically includes all non-prop related attributes - we don't need model, $listeners -> check out this presentation https://github.com/chrisvfritz/vue-3-trends/blob/master/slides-2019-03-vueconfus.pdf
• native portals <Teleport>
• In Vue 3, due to the availability of Fragments, it is recommended to use template refs for direct access to DOM nodes instead of relying on this.$el.
• Remove $on, $off and $once instance methods. Vue instances no longer implement the event emitter interface.

COMPONENTS ISSUES

rename custom directives hooks, be careful with v-bind="$attrs" this inherits also directives

more info: https://github.com/vuejs/rfcs/blob/master/active-rfcs/0012-custom-directive-api-change.md

• v-focus
• v-clickOutside
• v-focusTrap

Issues with two-way data binding, removed model prop

[v-model API Change] more info: https://github.com/vuejs/rfcs/blob/master/active-rfcs/0011-v-model-api-change.md

• SfCheckbox - v-model, issue with 'checked', use checked prop, remove model property
• SfInput - v-model, issue with 'value', add $emit with update:modelValue
• SfQuantitySelector - remove model, use modelValue, $emit with update:modelValue
• SfAddToCart - remove model, use modelValue
• SfRadio - v-model, issue with 'checked', use checked prop, remove model property
• SfModal - remove model
• SfSearch - use modelValue
• SfCollectedProduct - change $event to $event.target.value

Replace $listeners with v-bind="$attrs"

More info: https://github.com/vuejs/rfcs/blob/master/active-rfcs/0008-render-function-api-change.md

• SfArrow
• SfAddToCart
• SfBanner - fix $listeners
• SfBottomNavigationitem
• SfButton
• SfColor
• SfCircleIcon - remove $listeners
• SfIcon
• SfImage
• SfFilter
• SfMenuItem

this.$listeners has been removed

• SfInput

now v-bind="$attrs" inherit also classes and styles - check if this works

maybe this will be helpful -> https://github.com/vuejs/rfcs/blob/attr-fallthrough/active-rfcs/0000-attr-fallthrough.md

• SfInput
• SfQuantitySelector
• SfSearchBar

replace $on, $off and $once methods, proposition is to use the external library mitt
