quickfix, properties, jsx, literal

✅ Viability Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

⭐ Suggestion

We have:

{} is missing the following properties from type {} and {} more.

It's helpful to add all missing attributes/properties by quickfix. the default value could be null/undefined/zero-value/etc.

📃 Motivating Example

interface Foo {
  a: string
  b: number
}

const f: Foo = {}
--------------------------------
         ^ missing a, b
-------------------------------

To:

interface Foo {
  a: string
  b: number
}

const f: Foo = {
 a: undefined,
 b: undefined
}

It seems duplicate of #28491 (#44576), partially #16755 (#44781). The first PR was merged, however, I'm not sure if it was included in typescript-4-4-beta. I think @DanielRosenwasser can clarify that ;).

Looks cool! Don't forget jsx attributes too.
