LlamaIndex.TS was a data framework designed to facilitate the integration of custom data with large language models (LLMs) in JavaScript and TypeScript environments. It aimed to provide a lightweight and easy-to-use set of libraries for building LLM applications that could leverage proprietary information, supporting various JS runtimes like Node.js, Deno, and Bun, alongside numerous LLM providers. Although now deprecated and no longer maintained, its original purpose was to simplify the development of context-aware LLM applications by enabling Retrieval Augmented Generation (RAG) patterns.
