Specialize JSX error messages for missing properties

描述

import React from "react";

function Foo(props: { count: number }) {
    return <div>{props.count}</div>;
}

<Foo />

function Bar(props: { a: any, b: any }) {
    return <div />;
}

<Bar />

function Baz(props: { a: any, b: any, c: any, d: any, e: any, f: any }) {
    return <div />
}

<Baz />

Property 'count' is missing in type '{}' but required in type '{ count: number; }'.
Type '{}' is missing the following properties from type '{ a: any; b: any; }': a, b
Type '{}' is missing the following properties from type '{ a: any; b: any; c: any; d: any; e: any; f: any; }': a, b, c, d, and 2 more.

The 'count' attribute is missing, but is required for this 'Foo' tag.
This 'Bar' tag is missing the following attributes: a, b.
This 'Baz' tag is missing the following attributes: a, b, c, d, and 2 more.

研究方向

Investigate the TypeScript compiler's source code, specifically `src/compiler/checker.ts`, to locate where error messages for missing properties are generated (e.g., error code 2322). Analyze how JSX specific error messages are currently produced and identify the code path that handles `<Foo />` without required props. Then, modify the error message formatting to produce the proposed 'The 'count' attribute is missing...' style. The linked playground link provides test cases. The issue has an assignee, so coordinate with them before starting work.
