baby-workers v2.0.4

Baby workers Javascript

Execute and manage your code asynchronously with workers and promise. Execute each element of an array or a simple element in callback. Like thread, you can start and stop your jober where and when you want in your code. You can limit the number of jobers or execute it like a stack. Do everything asynchronously with baby-workers !

Install

npm install --save baby-workers

How is it works ?

Three entites :

• Root (instancied at the start of baby-wokers is the root level)
• Parent (parent instance is created after a worker.create to create nodes)
• Node (node instance created from parent is an independent function it can create a parent too).

Root -> worker.create(...) -> Parent -> .map('...', '...') or .set(...) -> .run() or .stack() or ... -> Node + Node

Usage

• First create a new parent with workers.create(name or function, function)
• Next set data or map array with workers.name.map(...) or workers.name.set(...)
• Then run parent to create nodes with workers.name.run() or workers.name.stack() or ...

workers.create('MyWorker', (worker, elem) => {
    setTimeout(() => {
        console.log('|=>', elem);
        worker.pop();
    }, (~~(Math.random() * 1000)));
}).map(['a', 'b', 'c', 'd']).limit(2).run().then(() => { // then is a promise
    console.log('Then MyWorker');
}).catch(() => { // catch is a promise
    console.log('Catch MyWorker');
});

workers.create('MyWorker2', (worker, elem) => {
    setTimeout(() => {
        console.log('|=>', elem);
        worker.pop();
    }, (~~(Math.random() * 1000)));
}).set(['a', 'b', 'c', 'd']).run().then(() => { // then is a promise
    console.log('Then MyWorker2');
}).catch(() => { // catch is a promise
    console.log('Catch MyWorker2');
});

workers.all(workers.MyWorker, workers.MyWorker2).then(() => { // then is a promise
    console.log('Then workers all');
}).catch(() => { // catch is a promise
    console.log('Catch workers all');
});

workers.then(() => { // then is not a promise
    console.log('Then workers');
}).catch(() => { // catch is not a promise
    console.log('Catch workers');
}).complete(() => {
    console.log('Complete workers');
});
