Helia is a streamlined, modular TypeScript implementation of IPFS designed for the JavaScript and browser environments, exemplifying modern web3 standards. It facilitates seamless data interaction, offering specialized modules for handling strings, JSON, DAG-JSON, and DAG-CBOR content types efficiently. By supporting a versatile custom hasher system, Helia allows for precise content addressing through various cryptographic hash algorithms. It leverages a modular architecture that empowers developers to customize implementations with distinct APIs, including peer-to-peer communication via bitswap and libp2p, or HTTP gateways. Helia’s suite of supplemental libraries and tools enhances distributed, trustless operations tailored to specific application needs. Version 1, launched in March 2023, continues to evolve with a focus on performance improvements and roadmap-driven initiatives. Helia encourages community engagement and contributions, providing extensive documentation and support channels for developers invested in decentralized technologies.
