A lean, modular, and modern TypeScript implementation of IPFS for JavaScript and browser environments.
Helia is a TypeScript implementation of the InterPlanetary File System (IPFS) protocol, enabling JavaScript and browser applications to interact with content-addressed, decentralized data. It solves the problem of building modern distributed web applications by providing a modular and performant IPFS stack tailored for JavaScript environments.
JavaScript and TypeScript developers building decentralized applications, browser-based dApps, or tools that require IPFS functionality in web or Node.js environments.
Developers choose Helia for its modular architecture, modern TypeScript design, and flexibility—allowing them to swap out components like networking or storage layers while maintaining full IPFS compatibility in JavaScript ecosystems.

Helia allows swapping components like libp2p, datastores, and blockstores, enabling custom setups as shown in the system diagram where users bring their own implementations.
Supports strings, JSON, DAG-JSON, and DAG-CBOR through dedicated modules, providing versatile data handling options demonstrated in the usage examples.
Built specifically for JavaScript and browser environments, making it ideal for decentralized web applications that need IPFS functionality in the client.
Offers a growing suite of libraries for IPNS, UnixFS, verified fetch, and more, as listed in the supplemental modules section.
The modular approach requires configuring multiple interdependent components, which can be daunting for developers new to IPFS or distributed systems.
As a relatively new project with v1 released in 2023, Helia may undergo breaking changes, and some features are still under development per the roadmap.
Core functionalities like IPNS or UnixFS require additional libraries, adding to bundle size and integration complexity compared to all-in-one solutions.
