Debug where action was called for redux-act

debug-action-call.js

function getStack() {
    // Save original Error.prepareStackTrace
    const origPrepareStackTrace = Error.prepareStackTrace;

    // Override with function that just returns `stack`
    Error.prepareStackTrace = (_, stack) => stack;

    // Create a new `Error`, which automatically gets `stack`
    // Evaluate `err.stack`, which calls our new `Error.prepareStackTrace`
    const { stack } = new Error();

    // Restore original `Error.prepareStackTrace`
    Error.prepareStackTrace = origPrepareStackTrace;

    // Remove superfluous function call on stack
    stack.shift(); // getStack --> Error

    return stack;
}

export function getCallers() {
    const stack = getStack();

    stack.shift(); // getStack
    stack.shift(); // getCaller

    // Return caller's caller
    return Array.prototype.map.call(stack, v => v.toString());
}

export const action = createAction(
