socket.dev Sponsor

Quickly evaluate the security and health of any npm package. Unlike a traditional vulnerability scanner, Socket can actually detect an active supply chain attack and help you to block it. Socket detects over 70 issues in open source code, for comprehensive protection.

Concurrent.js: load modules into web workers, access them asynchronously
github.com @beshan, @bitair-org

Concurrent.js dynamically loads modules into web workers. They can be accessed asynchronously from the main thread. Example:

import {concurrent} from '@bitair/concurrent.js';
const {MyClass} = await concurrent.load('./my-module.js');
const obj = await new MyClass('abc', 123);
const result = await obj.myMethod({first: 'Robin', last: 'Doe'});

Warning in readme: “This is an early version of the library and must not be used in a real project.”
