web3-rpc-failover

FailoverProvider via yaml configuration file for cascading connection fallbacks

Motivation

Providing assurances for Service Provider outages in a robust and simple way.

Do not confuse our usage of failover with how ethers-js uses fallback. see the ethers documentation, fallback provider

Install

npm i web3-rpc-failover

Usage: as an external module

• install web3-rpc-failover

• configure your RPC Service Providers in order of preference for failover

  providers:
    - url: 'https://mainnet.infura**'
      config:
        priority: 2
        stallTimeout: 200
        weight: 2
    - url: 'infura.io/zzz'
      config:
        priority: 1
        stallTimeout: 100
        weight: 1
  

  priority: priority used for the provider stallTimeout: timeout (in ms)

Usage: as a library
