YAWU - Yet Another Web Utilities

Description

Rails app with utilities such as JSON converter, XML formatter, XSLT transformation and XSD validator.

• Licensed under the terms of the MIT license
• Developed for closed networks (e.g. for enterprise network without internet access)
• Oriented on modern browsers (mostly tested with Firefox 32)
• Uses JRuby, thus can be deployed on almost any Servlet container (e.g. Tomcat, WebSphere) using Warbler or started as standalone server.
• Can be easily extended with your own tools based on text input and output (using Ajax.org Ace editor) or uploaded files.

Use cases

• You need simple utility functions, but you can't use ones from Internet (for security, NDA or whatever reason)
  • you can deploy this tool on local machine or network (DON'T USE IT IN THE INTERNET)
• You need to write and share simple script with non-programmers (e.g. generating test data)
  • you can implement it and share by link
  • you can use generator to create skeleton of new tool: bundle exec rails g editor <what_you_need>
• (Planned feature) You need to perform chain of actions, e.g. transform JSON to XML and validate this XML by XSD
  • you can set up chain of simple transformations

Run and develop

It's mostly regular Rails application. You can run it as standalone app:

RAILS_ENV=production bundle exec rails s

!!! For file uploading feature working you need file utility from *nix world.

Or build war and deploy to servlet container:

RAILS_ENV=production bundle exec rake war:create

It creates yawu.war ready for deploy. Application uses embedded database (Apache Derby), so updating war will erase old data.

Dockerfile which embeds DB and assets is available too:

docker build -f docker/Dockerfile -t yawu:<version> .
docker run -it yawu:<version> -p 3000
# or using docker-compose:
cd docker && docker-compose -f docker-compose.yml up -d
