    ☕ Dynamic code analysis for JavaScript


    Iroh is a dynamic code analysis tool for JavaScript. Iroh allows to record your code flow in realtime, intercept runtime values and manipulate program behaviour on the fly.

    Installation:

    npm install iroh
    

    or alternatively the browser distribution from here.

    Example:

    You can play with some live examples here and you can clone them from here.

    (A simple textual model is used here)

    Input

    function factorial(n) {
      if (=== 0) return 1;
      return n * factorial(- 1);
    };
    factorial(3);

    Output

    call factorial ( [3] )
      call factorial ( [2] )
        call factorial ( [1] )
          call factorial ( [0] )
            if
            if end
          call factorial end -> [1]
        call factorial end -> [1]
      call factorial end -> [2]
    call factorial end -> [6]

    Usage:

    • Runtime call tree graphs
    • Runtime type checking
    • Runtime code quality
    • Runtime test cases
    • Realtime code visualizations
    • Intercept eval, setTimeout etc.
    • Intercept and manipulate code/data on the fly
    • Visual learning
