What are all the index.ts used for?

Question

I\'ve been looking at a few seed projects and all the components seem to have a index.ts that exports * from that component. I can\'t find anywhere what it\'s actually used

Answer 1

index.ts help us to keep all related thing together and we don't need to worry about the source file name.

We can import all thing by using source folder name.

import { getName, getAnyThing } from './util';

Here util is folder name not file name which has index.ts which re-export all four files.

export * from './util1';
export * from './util2';
export * from './util3';
export * from './util4';
