Postgres Explain Visualizer (dev) is designed to make EXPLAIN output easier to grok. It creates a graphical representation of the plan. You can see it in action at tatiyants.com/pev, or read about it on my blog.
Pev is heavily influenced by the excellent explain.depesz.com.
Pev is written in angular 2 with TypeScript. The project is based on angular2 seed. It requires npm, gulp, tsd, and compass.
npm install
npm start
You may also need to install tsd and compass:
npm install tsd -g
gem install compass
To build, run the build command for a specific environment. For example, the following will create a production distribution:
npm start build.prod
