fixparser-common

Shared TypeScript interfaces, types, and utilities for the FIXParser ecosystem.

What is fixparser-common?

fixparser-common provides foundational building blocks for FIXParser and its plugins, including:

• Message storage interfaces and buffers for handling FIX messages
• Logging interfaces and types for consistent, pluggable logging
• Plugin interface for extensibility
• UUID generation utility
• Common types for messages and log levels

This package is not a standalone FIX engine, but is intended for use by FIXParser, its plugins, and related tools.

Main Exports

• IMessageStore<T>: Interface for generic message storage (add, retrieve, update, remove, etc.)
• MessageBuffer<T>: In-memory buffer implementing IMessageStore<T>
• ILogTransporter: Interface for pluggable log transport (e.g., to file, console, remote)
• LogMessage, Level: Types for structured logging
• IPlugin<T>: Interface for registering plugins
• IMessage: Interface for FIX messages
• uuidv4: Utility for generating UUID v4 strings

Example Usage

import { MessageBuffer, LogMessage, Level, uuidv4 } from 'fixparser-common';

// Message buffer for storing messages
const buffer = new MessageBuffer(100);
buffer.add({ messageSequence: 1, encode: () => 'FIX message' });

// Logging
const log: LogMessage = { level: 'info' as Level, message: 'Started FIX session' };

// Generate a UUID
const id = uuidv4();
