ipfrs-interface 0.1.0

HTTP, gRPC, GraphQL and Python interfaces for IPFRS distributed storage
Documentation

ipfrs-interface

API layer for IPFRS - HTTP Gateway and RPC interface.

Overview

ipfrs-interface provides external access to IPFRS functionality:

  • HTTP Gateway: Kubo-compatible web interface
  • RPC API: JSON-RPC and gRPC endpoints
  • High-Speed API: Custom optimized protocol
  • FFI Bindings: C/Python/Node.js integration

Key Features

HTTP Gateway (Kubo Compatible)

Standards-compliant gateway for IPFS clients:

  • GET /ipfs/{cid}: Retrieve content by CID
  • POST /api/v0/add: Upload files
  • POST /api/v0/cat: Download files
  • POST /api/v0/dag/: DAG operations
  • WebSocket Support: Real-time updates

High-Speed API

Custom protocol optimized for performance:

  • Binary Protocol: Faster than JSON
  • Streaming: Chunked uploads/downloads
  • Batch Operations: Multiple requests in one call
  • Zero-Copy: Direct buffer access

gRPC Interface

Type-safe, high-performance RPC:

  • Protobuf Definitions: Strongly typed API
  • Streaming Support: Bidirectional streams
  • Interceptors: Authentication, logging, metrics
  • Language Bindings: Auto-generated clients

FFI Bindings

Native library interface for embedding:

  • C API: Standard C-compatible interface
  • Python Bindings: PyO3-based wrapper
  • Node.js Addon: N-API native module
  • Safety Wrappers: Memory-safe abstractions

Design Principles

  • Performance: Built on Axum (fastest Rust web framework)
  • Compatibility: Wire-compatible with IPFS Kubo
  • Extensibility: Easy to add new endpoints
  • Security: Rate limiting, authentication, CORS

Usage Example

HTTP Gateway

use ipfrs_interface::HttpGateway;

// Start gateway
let gateway = HttpGateway::builder()
    .bind("0.0.0.0:8080")
    .enable_cors()
    .build()?;

gateway.serve().await?;

gRPC Server

use ipfrs_interface::GrpcServer;

// Start gRPC server
let server = GrpcServer::builder()
    .bind("0.0.0.0:5001")
    .add_service(ipfs_service)
    .build()?;

server.serve().await?;

FFI (C)

#include <ipfrs.h>

// Initialize node
ipfrs_node_t* node = ipfrs_node_new(config);

// Add file
ipfrs_cid_t* cid = ipfrs_add(node, data, len);

// Get file
uint8_t* data = ipfrs_cat(node, cid, &len);

// Cleanup
ipfrs_node_free(node);
