Exporting a function on typescript "declaration or statement expected"
TypescriptTypescript Problem Overview
I realize this is really simple but typescript seems to have changed a lot in the last years and i just cant get this done with previous answers i found here on stack overflow.
let myfunction = something that returns a function
export myfunction;
I get an error "declaration or statement expected"
How can i export a function from a really simple ts file to be able to use the function in another ts file?
Typescript Solutions
Solution 1 - Typescript
It seems that
let myfunction = something that returns a function
export {myfunction};
will do the trick.
Solution 2 - Typescript
Use
export default myfunction
if you only have this function to export from this file. Otherwise use
export { myfunction, <other exports> }
to export myfunction along with other types to export
Solution 3 - Typescript
You can call a function or instantiate a class from another file using modular top-level import and export declarations.
file1.ts
// This file is an external module because it contains a top-level 'export'
export function foo() {
console.log('hello');
}
export class bar { }
file2.ts
// This file is also an external module because it has an 'import' declaration
import f1 = module('file1');
f1.foo();
var b = new f1.bar();
