fallback-provider v1.1.0

Fallback Provider

Usage

• Create a config file for the backends to be used. Example -

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

  Priority: The priority used for the provider. Higher priorities are favoured over lower priorities. If multiple providers share the same priority, they are chosen at random.

  stallTimeout: The timeout (in ms) after which another Provider will be attempted. This does not affect the current Provider; if it returns a result it is counted as part of the quorum.Lower values will result in more network traffic, but may reduce the response time of requests.

  weight: The weight a response from this provider provides. This can be used if a given Provider is more trusted, for example.

• Add the package to the project
  npm i fallback-provider
  OR
  yarn add fallback-provider

• Import the provider as usual, i.e

  const {FallbackProvider} = require('fallback-provider')
  const provider = new FallbackProvider(<pathToConfig>)
