access exported interface from import * as

[sophister]

What code were you trying to parse?

// in file common.ts
export interface User {
  name: string;
  age: number;
};

export interface Profile {
  addr: string;
  city: string;
};

export enum Status {
  OK,
  Fail
};

// in another file  foo.ts
import * as all from './common.ts';
all.User;      // does not exist
all.Profile;   //does not exist
all.Status;  //OK

What did you expect to happen?
I can access interface with all.User and all.Profile
What actually happened?
import * as lost exported interface

It looks like you've posted this to the wrong repo!

@bradzacher thx for your reply. But typescript itself can handle this case. I've written a demo here:
https://codesandbox.io/s/tsexportinterfaceall-8ro9k . But when I use typescript-eslint, interface does not exist in the all .

I don't quite understand what the problem is?

What is the error message you're seeing?
That demo doesn't show any specific errors with the eslint parsing, or the eslint rules.

You're saying that the interfaces do not exist on all, but in your demo they clearly do?

Additionally - @typescript-eslint/parser does not deal with typechecking - all it does is takes the code you write and converts it to an AST.

Please let me know the issue you have found with @typescript-eslint/parser.

@bradzacher I just found that, using all.Status is ok, I just can't use javascript object spread syntax with all. So it has nothing to do with typescript-eslint. sorry

// this does not work
const { Status, Profile } = all;
// this is valid
all.Status
all.Profile
