Installation

Install the gem and add to the application's Gemfile by executing:

$ bundle add throttled_json_rpc_client

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install throttled_json_rpc_client

Usage

example1, without rate throttling

rpc_url = "https://1rpc.io/eth"

eth = JsonRpcClient::Eth.new(rpc_url)

p eth.block_number

example2, with rate throttling

The rate limit on the server is called Rate Limiting, and the rate limit on the client is called Rate Throttling.

This rate throttling can be used in multi-threaded, multi-process, multi-machine environments.

rpc_url = "https://1rpc.io/eth"

# default equals to ThrottledJsonRpcClient::Eth.new(url, rate: 5, interval: 1, redis_urls: ["redis://localhost:6379/2"])
eth = ThrottledJsonRpcClient::Eth.new(rpc_url)

threads = []
10.times do
  threads << Thread.new do
    p eth.block_number
  end
end
threads.map(&:join)
