# Platform Socket.io

## What it is responsible for

Platform Socket.io manages the Socket.io-facing platform boundary represented by `IoAdapter`, connecting this package with its named `Websockets` and `Common` dependencies. Its documented entry points are `Readme.md` and `IoAdapter`, so the README supplies the package’s public orientation while the adapter is the identified code entry. The available comments describe Nest as a framework for Node.js server-side applications and direct readers to its guide and official support channels; they do not state further Socket.io-specific behavior.

## What it needs, and who needs it

This package depends on `Common` and `Websockets`; both are named dependency edges rather than described APIs. `sample/02-gateways/src/adapters` depends on Platform Socket.io, making that sample the stated downstream consumer. Without this package, that dependency relationship cannot be satisfied. The evidence does not identify a specific runtime failure or an alternative adapter path. Likewise, it does not explain how `Common` or `Websockets` are used.

## Notable members

`IoAdapter` is the sole identified class and a work-entry symbol; it carries the code-level responsibility visible in the evidence. `Readme.md` is the other work entry and documents the project’s guide, Discord questions-and-support route, issue-reporting checklist, consulting, sponsorship, and MIT license. No methods or protocol are named, so no behavior is characterized.

31 entities in `packages/platform-socket.io`. Nothing else in this repository depends on it.

## What it is made of

Its 31 entities sit in 2 files under `packages/platform-socket.io`: 29 doc comments, 1 markdown doc and 1 class.
`IoAdapter` declares 5 methods, the widest surface here.

## Where work enters

- `Readme.md` — `packages/platform-socket.io/Readme.md`:1
- [`IoAdapter`](class-ioadapter) — `packages/platform-socket.io/adapters/io-adapter.ts`:14

## How it refuses and fails

1 of its components records a refusal or a failure handler.
It refuses work outright, under a condition written into the component itself.

## Boundaries

It depends on `Common`, `Websockets`, and on nothing else in this repository.
