Faraday 3.0 Wishlist

[iMacTia]

I want to start collecting ideas for things we want to do in Faraday 3.0.
This is a work in progress list and will be updated over time based on feedback 📊

List of fearures

• Use SNAKE_CASE constants consistently
• Kill Faraday::Utils
• Faraday::Connection => Faraday::Client
• Remove Options structs in favor of properties on Client/Request/Response
• Remove env in favor of request/response object properties
• Consistent #response property on HTTP-related error classes (RaiseError, RetriableRequest, etc) [Can not view details of failed requests  #1284]
• Revisit adapter/middleware internal API (drop Rack adapter semantics)
• Redesign Faraday::Connection and Faraday::RackBuilder relationship
  • Remove use/adapter/etc delegation
  • Faraday::RackBuilder#handlers => Faraday::Connection#handlers
• Reorganize middleware lib/faraday/middleware/*
• Retry mw: extract exponential backoff timing stuff
• Logging/Instrumentalization: built into Faraday, usable by any middleware
• Streaming by default, while providing easy access to cached string response bodies
• Built-in multipart support with better api.
• Revisit pipelining or parallel requests (net-http-pipeline, typhoeus)
• Consistent response error raising (/cc #1042)
