process-control
Set up asynchronous processes that can be started, restarted, stopped and disposed.
This project was created to manage complex rendering logic. It allows you to define several processes that can at any time be started, stopped, restarted or disposed. When you stop a process its current step will finish, but the next step will not execute. Think of it as using a promise which by default executes synchronously and can be stopped, restarted and disposed (can not be started anymore).

; const myProcess = // Automatically dispose when the process reaches its end dispose: true // Do some work and return a value for the next step // Do some work and return a promise to hold further execution // Do work in parallel all Promise otherProcess // Compose in an other process instance ; // Return a function that works like a synchronous promise, meaning that // calling resolve() will instantly trigger the next step, not on next // tick as native promises do /* Start the process. If you try to start a running process, it will stop the current one, and once stopped start again. Returns a promise*/myProcessstartoptionalValue; /* Stop the process. Current started process promise will throw an exception.*/myProcess; /* Restart the process. Stops the current process and then starts when it is stopped.*/myProcess; /* Disposes the process. Nothing happens when you try to start it.*/myProcess; /* The state of the process*/myProcessstate;
NB! Be careful composing one process into multiple other processes. As one process might try to stop the composed process while the other expects it to do its work!
