Parse URL query params

[crookse]

Summary

What:

When connecting to the server, the URL query params should be parsable and usable by the user.

Why:

A use case came up in the Discord where a user asked if parsing query params was possible. Also, it allows more flexibility in handling connections. For example, if a user wanted to make their server auto connect a user to a certain channel based on a query param, they would be able to do that.

Acceptance Criteria

Below is a list of tasks that must be completed before this issue can be closed.

• URL query params are parsable in the event listener (see example pseudocode)
• Write documentation
• Write unit tests
• Write integration tests

Example Pseudo Code (for implementation)

const server = new Server(...)
await server.run(...)
const urlQueryParams: Record<string, string> = {};
server.on("connect", (packet) => {
  const url = packet.from.url
  const queryString = url.split("?")[1]
  if (queryString) {
    const parts = queryString.split("&")
    for (const part of parts) {
      const [name, value] = part.split("=")
      urlQueryParams[name] = value
    }
  }
})

console.log(server.queryParams) // {}, not set yet
server.on("join", () => {
  console.log(server.queryParams) // { "path": "someValue" }
})
