Common logic used across all Kinto services

KintoHub Go Utils

A project that holds common logic used across all go services @ KintoHub.

General Rules

• Postfix a function with OrDie means that it will throw a panic and is used during the startup of the app
• Prefix a fucntion with Run means that it is a blocking function that will not stop and go into an infinite loop. (Usually good to be called with go threads unless using it for a specific cause)

Logger

Basic logger using zero log. This is a dependency across all of utils and expected to call InitLogger to set it up.

Logger expects an environment variable LOG_LEVEL of value VERBOSE, DEBUG, INFO, WARN, ERROR, PANIC, FATAL

Server

Server currently only has an implementation of grpc but may have future server implementations such as fasthttp, websockets etc. There are common utilities within server so that it can be abstracted. Most importantly, server/utils/errors.go can be used to create standard errors across different server implementations so that your business logic can return errors such as NotFound or Internal and depending on the implementation, it will handle the error code and message gracefully.

Additionally, any errors that are returned and sent out will be automatically logged through middleware. So logging errors is unnecessary when using this package.

Config

Config package has utility functions to load configuration from environment variables with ease.

Utils

Utils package has basic logic that is reused across projects.
