Bad package reference causes error on upstream builds

[jasonkenneth]

We're keeping our dependencies up to date on an Angular 12 / nestjs / nrwl monorepo application. When I upgraded to the latest versions of socket.io, I get a build error from within node_modules.

Error: node_modules/engine.io/build/transport.d.ts:4:10 - error TS2305: Module '"engine.io-parser"' has no exported member 'Packet'.

4 import { Packet } from "engine.io-parser";
           ~~~~~~

It turns out it's because the vLatest of engine.io actually requires at least engine.io-parser v5.0.3, but the reference only pulls ~5.0.0. If I install engine.io-parser directly in my app to 5.0.3, the build error disappears.

engine.io/package.json

Line 42 in 90fb0a9

"engine.io-parser": "~5.0.0",

This should be fixed by 1bc5b1a, included in engine.io@6.1.3.
