Mutation testing Real time

A NodeJS helper package to help with the server side of real-time reporting.

Usage example

import { createServer } from 'http';
import { RealTimeReporter } from 'mutation-testing-real-time';

const reporter = new RealTimeReporter({ accessControlAllowOrigin: '*' });
const server = new createServer((req, res) => {
  if (req.url === '/sse') {
    reporter.add(res);
  }
});

// Whenever a mutant result comes in:
reporter.sendMutantTested({ id: '1', status: 'Killed' });
// ...

// Whenever we are done:
reporter.sendFinished();
