# @tanstack/devtools-event-client

This package is still under active development and might have breaking changes in the future. Please use it with caution.

## General Usage

```tsx
import { EventClient } from '@tanstack/devtools-event-client'

interface EventMap {
  'query-devtools:a': { foo: string }
  'query-devtools:b': { foo: number }
}

class QueryDevtoolsPlugin extends EventClient<EventMap> {
  constructor() {
    super({
      pluginId: 'query-devtools',
    })
  }
}

export const queryPlugin = new QueryDevtoolsPlugin()

// I'm fully typed here
plugin.emit('a', {
  foo: 'bar',
})
plugin.on('b', (e) => {
  // I'm fully typed here
  e.payload.foo
})
```

## Understanding the implementation

The `EventClient` class is a base class for creating plugins that can subscribe to events in the TanStack Devtools event bus. It allows you to define a set of events and their corresponding data schemas using a standard-schema based schemas.

It will work on both the client/server side and all you have to worry about is emitting/listening to events.

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
