Middle Earth

This is a common module that the backend and frontend can use.

It has been installed on frontend so just run npm i there.

Build and Run

1. npm i
2. npx tsc
3. go to your project and use: npm install [email protected]:Missile-Wars-Revival/middle-earth.git

Using

Open index.ts to view the available types. They can be imported through:

import { Player } from "middle-earth";

Sending / Serializing

In your code, prepare a WebSocketMessage with however many Msgs you like, and then feed it into zip() to serialize and compress it, returning a Buffer. Send this over the websocket.

Receiving / Deserializing

Take the incoming Buffer and pass it as an argument to unzip(). It will return a WebSocketMessage containing several Msg types.

Full-Stack Websocket Message Protocol

A full stack protocol is defined here. We'll use messagepack which is a compressed version of JSON. This is a draft and if you think we should change something make a PR or comment.

Some types can be used bi-directionally. This means it is appropriate for the server to send the type to the client and the client can also send that type to the server. I have doubts whether bi-directional types will work long term.

The WebSocketMessage Type

This is the base message type. Anything sent over websockets will use this type. It will send a list of messages with the Msg type.

The Msg Type

The message is an abstract type that all others will implement.

Msg Child Types

Missile, Landmine, MissileHit, and others inherit from Msg.
