PowerStation

Powerstation is a tool that finds performance bugs in Rails applications, for example, API misuse, repeated query, etc.

Using the tool

There are two ways to use Powerstation:

  • As a RubyMine plugin that you can download from the jetbrains website. The source code is included in this repo under powerstation/IDE_plugin.

  • As command line tool. The instructions and source code are included in this repo under powerstation/command_line_tool.

Both of these uses a static code checker that we have built to detect performance issues. The source code of the checker is in static-checker.

These are packaged in two separate branches (IDE_plugin, static-checker) in case you prefer checkout each part individually, for example:

$ git clone -b static-checker --single-branch https://github.com/hyperloop-rails/static-checker.git

Currently detected bugs

  1. Loop invariant queries

  2. Dead store queries

  3. Unused data-retrieval queries

  4. Common sub-expression queries

  5. API misuses

  6. Inefficient data rendering

Details of these are explained in our documentation.
