Libraries Needed for any Language

required_libs.txt

I'm making this list specifically for any language but I have golang in mind.

Persistence Clients
- mysql
- postgres
- redis
- memcache
- mongodb
- elasticsearch
- solr
- DB ORM


Network
- http client (bonus points here for api since this is used everywhere)
- protocol buffers or thrift
- statsd client


Testing
- unit testing
- mocking / stubbing
- bdd and/or cucumber
- file watcher and automatic test suite firing
- something that captures network traffic and replays it (vcr/fakeweb)
- setting expectations on outbound interface for http (faraday stubs), test interface not response.


Debugging
- repl
- breakpoints


General Tools
- xml and json parsing
- configuration file reading, constants/preferences
- web framework for json rest services (!)
- in memory database


Deployment and Ops
- auto deployment
- metrics within the app, tickers etc
- logging to a format logstash can understand
