ts-file-exports

A utility for getting all the named exports of a TypeScript or JavaScript file.

What kinds of module exports are supported?

In .ts files:

• Typescript exports, and typescript wildcard exports In .js files:
• ES Modules exports including wildcard exports
• CommonJS exports

For more details on the supported export types, see the tests/cli.ts file and the fixtures/ folders.

How to use from CLI

yarn global add ts-file-exports
# or 
npm install -g ts-file-exports

Then:

ts-file-exports path/to/ts/or/js/file.ts

It will print the names of the exports in that file, each on a separate line.

How to use as an API

import getExports from 'ts-file-exports';

const exports: string[] = getExports('path/to/ts/or/js/file.ts');
console.log(exports);
// Prints an array of string names of the exports for the referenced file.

How does it work?

It just loads typescript to parse/analyze/check the file. Then it calls to the checker.getExportsAndPropertiesOfModule TypeScript API.

It's pretty slow...

Yes, it has to spin up all of TypeScript to be able to work.
