Data Filter Functions

Bytengine allows you to filter/modify commands results by redirecting their output to Filter Functions (or user defined functions). This feature comes in handy especially when you want to process the data server-side before returning it to your application. The syntax to redirect output is >> function_name and can be used after any bfs command.

Currently only a sample function pretty which pretty prints bfs commands is included as an example but further useful ones will be added eventually. You can view the filter function plugin code implementation in /bytengine/fltcore/fltcore.go.

Example: "name" in /users >> pretty "name" in /users >> my_custom_function
