The axiom-js repository is the official JavaScript and TypeScript language bindings and library extensions for Axiom, a data analytics and observability platform. Hosted at https://axiom.co, this monorepo is structured to provide multiple integration points for developers working in the JavaScript ecosystem who need to ingest or query data through Axiom's services.
The repository contains four main packages. The @axiomhq/js package provides the official API bindings that form the foundation for data ingestion and querying operations. The @axiomhq/winston package integrates with the popular Winston logging library, allowing developers to configure Winston as a transport that automatically sends logs to Axiom. Similarly, the @axiomhq/pino package provides integration with the Pino logging framework, enabling Pino-based applications to stream logs to Axiom. The @axiomhq/tanstack-start package offers observability utilities specifically designed for TanStack Router in single-page applications and TanStack Start applications, extending Axiom's monitoring capabilities into modern full-stack frameworks.
The project requires Node.js version 20 or higher, having dropped support for Node.js 18. It is distributed under the MIT License, making it freely available for both open-source and commercial use.
The repository is classified across a comprehensive range of technical domains reflecting its role as an observability and logging infrastructure library. These classifications include logging, distributed tracing, metrics collection, real-time analytics, and performance monitoring. The codebase demonstrates patterns associated with plugin architecture, dependency injection, configuration management, and protocol abstraction. The library is positioned within the broader ecosystem of modern web development tools, supporting asynchronous communication patterns and high-performance networking requirements.
The axiom-js repository shares contributors with other notable projects including prefecthq/prefect and typeorm/typeorm, indicating cross-pollination of ideas and practices within the data infrastructure and ORM communities. The inclusion of axiomhq/next-axiom in the overlapping contributor network suggests a complementary ecosystem of Axiom integrations tailored for specific frameworks.
The monorepo structure allows developers to adopt only the specific integrations they need while maintaining consistency across the Axiom JavaScript ecosystem. Whether using Winston, Pino, or TanStack frameworks, developers can leverage the underlying @axiomhq/js bindings through purpose-built transports and utilities that abstract away the complexity of direct API interaction.
