+# Summary
+
+Introduce a Composition Class Component to allow better typed components.
+
+This will allow components to have types to be inferred at runtime.
+
+The class will be very limited and only support Vue Composition-API **like** configuration.
+
+`Props` should be handled by Typescript, meaning that all the attributes passed to the component will be exposed as props. https://github.com/vuejs/rfcs/pull/281
+
+# Basic example
+
+```ts
+// Simple implementation
+abstract class VueComponent<Props, Emits = {}, Slots = {}, RawBindings = {}> {
+  protected context = {} as SetupContext<Emits>; // passed at runtime
+  protected props = {} as Props; // passed at runtime
+
+  abstract setup(): RenderFunction | RawBindings;
+}
+
+class Comp<Item> extends VueComponent<{
+  item: Item;
+  id: keyof Item;
+}> {
+  setup() {
+    // access context
+    this.context;
+
+    // access props
+    this.props;
+
+    return {
+      a: ref(1),
+    };
+  }
+
+  template = `<div>{{ a }}</div>`;
+}
+```
+
+# Motivation
+
+Motivation is to allow users to express complex types and infer certain prop type at "runtime" (when declaring the `<my-component />`)
+
+```ts
+// currently is using a class because of a limitation on typescript
+class MyClass<T extends Record<string, any>> extends VueComponent<
+  { items: T; keyPath: keyof T; cols: Array<keyof T> },
+
+  // emits
+  {
+    select(item: T): void;
+    "update:modelValue"(item: T): void;
+    cellClicked(col: keyof T, item: T);
+  },
+
+  // slots https://github.com/vuejs/rfcs/pull/192
+  {
+    [K: `head:${keyof T & string}`]: { a: number };
+    [Y: `item:${keyof T & string}`]: { b: string };
+  }
+> {
+  slots: = {} as any; // https://github.com/vuejs/rfcs/pull/192
+
+  emits = {
+    select(item: T) {},
+    [`update:modelValue`](item: T) {},
+    cellClicked(col: keyof T, item?: T) {},
+  };
+
+  setup() {
+    this.props
+    // declaration for testing
+    const a = this;
+    const cols: Array<keyof T & string> = [];
+    const slots: Record<keyof typeof a.slots, Function> = {} as any;
+    const item: T = {} as any;
+    // / declaration for testing
+
+    // render example
+    return ()=> h("table", [
+      h("thead", [this.props.cols.map((x) => h("th", [this.context.slots[`head:${x}`](this.props.items[0])]))]),
+    ]);
+  }
+}
+
+// or it can be used to enhance type of `defineComponent`
+
+class Comp<T extends Record<string, any>> extends VueComponent<
+  { items: T; keyPath: keyof T; cols: Array<keyof T> },
+
+  // emits
+  {
+    select(item: T): void;
+    "update:modelValue"(item: T): void;
+    cellClicked(col: keyof T, item: T);
+  },
+
+  // slots https://github.com/vuejs/rfcs/pull/192
+  {
+    [K: `head:${keyof T & string}`]: { a: number };
+    [Y: `item:${keyof T & string}`]: { b: string };
+  }
+>
+
+const comp = defineComponent({ /* options */}) as typeof Comp; // this will "trick" typescript and set the correct type.
+```
+
+# Detailed design
+
+This API will is simply a way to circunvent the losing of the generics when you you extract types from a function, the class component provides the generic typing with a nice syntax (this could be done with a `function` but there's too many hacks involved)
+
+API is kept simple and is not a replacement of `Vue Class Component`, this `Vue Class Composition` is meant to **only** support composition-api, options API are not meant to be supported
+
+# Drawbacks
+
+One more API to `defineComponent` and users might get confused with `Vue Class Component`
+
+# Alternatives
+
+There's some hacky ways to achieve this which follows some of this proposal: https://github.com/vuejs/vue-next/pull/3682
+
+# Adoption strategy
+
+If we implement this proposal, how will existing Vue developers adopt it? Is
+this a breaking change? Can we write a codemod? Can we provide a runtime adapter library for the original API it replaces? How will this affect other projects in the Vue ecosystem?
+
+This is intened for highly advance scenarios and not intended for begginners, the users who will take the most of this are:
+
+- Enterprise apps, which require an outstanding level of typing.
+- Micro performance improvements (https://github.com/vuejs/rfcs/discussions/276)
+- Component library creators.
+
+# Unresolved questions
+
+- Will this confuse users? 
+- Fine tunning the way users interact with the `Class Composition`
