module to queueing a array of functions
npm install --save nexting-queuelet counter = 0;
const promise1 = (next, error, param) => {
counter++;
assert(param === 'test');
new Promise((resolve) => setTimeout(resolve, 50))
.then((res) => next(null, res));
};
const promise2 = (next, error, param) => {
counter++;
assert(param === 'test');
};
const promise3 = (next, error, param) => {
counter++;
assert(param === 'test');
new Promise((resolve) => setTimeout(resolve, 500))
.then(() => {
assert(counter === 4);
done();
});
};
const promise4 = (next, error, param) => {
counter++;
assert(param === 'test');
};
const queue = queueNext([], 3, 'test');
queue.push(promise1, promise2, promise3, promise4);Every function is exec with next function, error pass by before function executed, otherArgs passed to nextingQueue and extraArgs passed to next in before called.
exec(next, error, ... otherArgs, ... extraArgs)
nextingQueue check for exec at most future functions.
arrayWithPushOverWritten has the push method over written to catch every push to queue the function pushed.
