  • Validation Checking
  • updating (replacing replacable notes)
  • Handle REQs (requests)
  • Handle CLOSE

Go Relay Archetecture for Implementing Nostr

GRAIN is an open-source Nostr relay implementation written in Go. This project aims to provide a robust and efficient Nostr relay that supports the NIP-01 protocol, focusing on processing user metadata and text notes.

Features

  • NIP-01 Protocol Support: GRAIN fully supports the NIP-01 protocol for WebSocket communication.
  • Event Processing: Handles events of kind 0 (user metadata) and kind 1 (text note).
  • MongoDB 🍃: Utilizes MongoDB to store and manage events efficiently.
  • Scalability: Built with Go, ensuring high performance and scalability.
  • Open Source: Licensed under the MIT License, making it free to use and modify.

Installation

  1. Clone the repository:

    git clone https://github.com/oceanslim/grain.git
cd grain

  2. Build the executable:

    go build -o grain.exe

    The grain.exe will be placed in a temporary directory within ...\appdata\local\temp\go-build and subdirectories.

Usage

To run the GRAIN relay:

./grain.exe

Configuration 🍃

Configuration options can be set through environment variables or a configuration file. Example configuration:

server:
  port: 8080
database:
  type: mongodb
  connection_string: mongodb://localhost:27017
  database_name: grain
logging:
  level: info

WebSocket Endpoints

  • Connect: / - Clients can connect to this endpoint to start a WebSocket session.
  • Publish Event: Send events of kind 0 (user metadata) or kind 1 (text note) to the relay.
