6.0.0

The codebase was migrated to TypeScript (c0d6eaa)

An ES module wrapper was also added (401f4b6).

Please note that the communication protocol was not updated, so a v5 client will be able to reach a v6 server (and vice-versa).

BREAKING CHANGES

• the default export was removed, so the following code won't work anymore:

const eioServer = require("engine.io")(httpServer);

Please use this instead:

const { Server } = require("engine.io");
const eioServer = new Server(httpServer);
