liteparse-grpc: gRPC Server for LiteParse Document Parsing
Blog post from LllamaIndex
LiteParse is a Rust-based library designed for parsing unstructured documents, such as PDFs and Office files, and can be accessed through various programming languages, including Node.js, Python, and WebAssembly. The library has expanded its network accessibility by introducing a gRPC server, @llamaindex/liteparse-grpc, alongside its existing REST server. While the REST server is suitable for simple HTTP clients and multipart uploads, the gRPC server, built on the Node.js bindings library, is more efficient for backend service calls by utilizing Protocol Buffers for typed contracts and binary framing. The gRPC service includes three RPC operations—Parse, Screenshot, and IsComplex—that mirror the REST server's capabilities and offers configuration through a LiteParseConfig message, providing control over parsing behavior. Users can quickly deploy the server using Docker or an npm package, and the package also includes a client binary for command-line interaction. The gRPC interface is especially beneficial for service-to-service communications, complementing the REST API without replacing it.
