v6.0.0-rc1

Breaking Changes

• Bumps minimum Node from 10 to 12
• Renamed default export API to EasyPostClient
• Overhauled the data flow of the library
  • Instead of creating a local object and then calling .save() on it to create/update it at the API level, you will pass in the same data as before but to one of either create() or update() functions on the service in question
  • The base service no longer implements all functions and instead each individual service implements its own functions. This means the library namespace won't be cluttered with various notImplemented functions
  • All instance functions (excluding lowestRate) previously called on an object are instead called on a service. (eg: shipment.buy(shipment.lowest_rate()) is now client.Shipment.buy(shipment.id, shipment.lowest_rate())))
    • All functions attached to a service are now async and must be awaited
• Moved library structure around
  • Introduced /models that contain the EasyPost objects
  • Renamed /resources to /services to better reflect that a service called against an EasyPostClient differs from an API resource, now known as the models
  • Each service file now has _service appended
  • Added /utils which contains both internal_util.js which is not intended for user consumption and util.js which contains public utilities
  • Moved getLowestSmartRate and validateWebook function to util.js as neither of them require the client object to function
• References of Referral were changed to ReferralCustomer to match the API
• Bumps major versions of all dependencies
• Changes the primaryOrSecondary parameter name to priority in billing functions to match the API
• Empty response functions now return nothing (deleting records, funding a wallet, etc)
• Explicit type parameter for retrieving all reports removed, include type in generic params dictionary instead.
• Improves error handling
  • Specific error types for each category of error
  • API error message may be an array rather than a string. Arrays will be concatenated (by comma) and returned as a string.
• Corrects references of smartrate to SmartRate and smartRate to match the API

New Features

• Add retrieveStatelessRates and getLowestStatelessRate functions

Bug Fixes

• Completely overhauled deserialization process, nested objects (eg: rates of shipments, etc) now properly convert to their appropriate EasyPostObject
• Fixes the verifyAddress function to actually verify an address
• Fixes a bug that could double wrap or unintentionally wrap the results of an /all API call with the name of the object in question
