Is there a syntax for wildcard export as?

Question

There is the import syntax:

import * as foo from 'bar';

I similarly tried:

export * as foo from 'bar';

but that threw the errors:

ERROR in src/app/@theme/components/aComp/aComp.loader.ts(1,10): error TS1005: 'from' expected.
src/app/@theme/components/aComp/aComp.loader.ts(1,13): error TS1005: ';' expected.
src/app/@theme/components/aComp/aComp.loader.ts(1,17): error TS1005: ';' expected.
src/app/@theme/components/aComp/aComp.loader.ts(1,22): error TS1005: ';' expected.

there is also the export syntax:

export { default as foo } from 'bar';

Is there a way to do this for * as opposed to default?

(FYI I'm trying to remove require from the statement):

export const foo = require('bar');

the error below is thrown when ng serve is run including the .ts above:

ERROR in src/app/@theme/components/aComp/aComp.loader.ts(6,20): error TS2304: Cannot find name 'require'.

What exactly would an `export * as foo` do? How exactly would that `require` line work without `require`? — deceze, Jul 25 '18 at 12:25
@deceze I don't have much idea. I'm just trying to remove `require` as tslint bugs me about it. — Nae, Jul 25 '18 at 12:30
@HyyanAboFakher That does work indeed. Wondered if there was a better way. — Nae, Jul 25 '18 at 12:31
Then perhaps tell us how tslint bugs you about it and ask us what to do about that. See http://xyproblem.info. — deceze, Jul 25 '18 at 12:32

No, there is not, but there is a proposal to add this syntax to the language.

Currently, you will need to use

import * as foo from 'bar';
export { foo }; // verbose: { foo as foo }

which is actually even closer to export const foo = require('bar'); than export * as foo from 'bar';, as it does provide foo in the local module scope as well.

Thanks. Does this account for `const` as well? – Nae Jul 25 '18 at 13:03

@Nae You mean the `const` in `const foo = require('bar');`? Yes, the imported namespace object is immutable. – Bergi Jul 25 '18 at 13:32
