# Figma Messaging

> Messaging library for Figma plugin developers

## Overview

Figma Messaging is a type-safe, auto-completing wrapper for Figma's [Messaging API](https://www.figma.com/plugin-docs/creating-ui/#sending-messages-between-the-ui-and-plugin-code).

Set up correctly, it can auto-complete...

...handler **responses**:

You can use Figma Messaging in any [Figma Plugin](https://www.figma.com/plugin-docs/) for robust, two-way messaging between `main` and `ui` processes.

## Services

The package comprises two services, `ipc` and `bus`:

`ipc` is a low-level inter-process communication service which provides:

- two-way communication between `main` and `ui` processes
- awaitable call and response
- catchable errors
- optional logging

`bus` is a higher-level message bus service (which wraps `ipc`) to provide:

- a formalised routing and handler setup
- IDE auto-completion of known route names and parameters
- typed parameter and return data for known routes
- flexibility to call arbitrary / unknown routes 
- fallback handler for arbitrary / unknown routes

Generally, [bus](docs/bus.md) will be your first choice as it's more feature-rich and user-friendly.

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.
