Description
What rule do you want to change?
vue/component-api-style
Does this change cause the rule to produce more or fewer warnings?
Fewer warnings
How will the change be implemented? (New option, new default behavior, etc.)?
New option composition-vue2
Please provide some example code that this change will affect:
const MyComponent = Vue.extend({
render(h) {
return h('div');
},
});What does the rule currently do for this code?
With configuration "vue/component-api-style": ["error", ["composition"]], it warns about using the render function:
Options API is not allowed in your project.
renderfunction is the API of Options API. Use Composition API instead.
What will the rule do after it's changed?
With configuration "vue/component-api-style": ["error", ["composition-vue2"]], it won't warn about using the render function, but still about using computed, methods, etc.
Additional context
Render functions cannot be replaced by returning h(…) from setup in Vue 2 with the Composition API plugin: https://github.com/vuejs/composition-api#template-refs
