xunnamius / toss-expression

A tiny ponyfill for @babel/plugin-proposal-throw-expressions, the syntax from which TypeScript and VS Code do not (yet) support

toss-expression

While Babel supports throw expressions via plugins, TypeScript and VS Code do not (yet). Hence this five line ponyfill takes the place of the currently-unavailable @babel/plugin-proposal-throw-expressions syntax.

// Though the following is supported by Babel, VS Code/TypeScript will complain
const userToken = secureRequest() || throw new SecureAccessError('badness occurred');

// No errors
const userToken = secureRequest() || toss(new SecureAccessError('badness occurred'));

Installation and Usage

npm install toss-expression

// ESM
import { toss } from 'toss-expression';
console.log(successMessage() || toss('log operation failed'));

// CJS
const { toss } = require('toss-expression');
console.log(successMessage() || toss('log operation failed'));
