How to reexport `*` from a module that uses `export =`

Question

I have a module m:

export = {
    a: 3
}

And then in my index.ts I want to re-export everything that m is exporting, so I use:

export * from './m';

But it gives me an error:

Error: TS2498:Module D:/Projects/typescript/m uses export = and cannot be used with export *.

How to re-export from a module that uses export= syntax? I have no control over the module with export= syntax.

Answer 1

You can use

import m = require("./m");
export {m};

or

import m = require("./m");
export default m;

Old style imports export =, require() aren't compatible with module exports.

Refer to documentation

UPDATE for JSON file import The following works using the from syntax, once you turn on the required tsconfig option. Available since 2.9.

import myObjectName from './path/to/file.json';
export { myObjectName };
