TextMaster uses AWS S3 for storage, so s3-compatible libraries/toolkits can be used (for example, EvaporateJS). However, it is quite simple to do it with a basic HTTP client library, which is capable of doing GET/PUT requests.
The process consists of 4 steps:
When running this command for the first time
$ bundle exec rake db:create
you may get this error
Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "pool"=>5, "username"=>"tulenmenu", "password"=>"tulenmenu", "database"=>"tulenmenu_development"}
