@hashtagchris/typescript-lib

A registry package with a TypeScript entry point and erasable TypeScript syntax. A JavaScript distribution is NOT included with this package.

Doesn't work with the Node.js runtime

While Node has some support for running TypeScript code, you can't use this package, at least not with Node 25. Dependents will hit ERR_UNSUPPORTED_NODE_MODULES_TYPE_STRIPPING. See https://github.com/nodejs/node/issues/57215#issuecomment-2689347639 for why this is by design.

Usage Test

const { add } = require('@hashtagchris/typescript-lib');

console.log(add(2, 3));

Error

% npm install @hashtagchris/typescript-lib

% node test-typescript-lib.js
node:internal/modules/typescript:183
    throw new ERR_UNSUPPORTED_NODE_MODULES_TYPE_STRIPPING(filename);
