kandi X-RAY | asap Summary

asap is a JavaScript library typically used in Server, Runtime Evironment, Nodejs applications. asap has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can install using 'npm i falcor-asap' or download it from GitHub, npm.

Promise and asynchronous observer libraries, as well as hand-rolled callback programs and libraries, often need a mechanism to postpone the execution of a callback until the next available event. (See Designing API’s for Asynchrony.) The asap function executes a task as soon as possible but not before it returns, waiting only for the completion of the current event and previously scheduled tasks. This CommonJS package provides an asap module that exports a function that executes a task function as soon as possible. ASAP strives to schedule events to occur before yielding for IO, reflow, or redrawing. Each event receives an independent stack, with only platform code in parent frames and the events run in the order they are scheduled. ASAP provides a fast event queue that will execute tasks until it is empty before yielding to the JavaScript engine's underlying event-loop. When a task gets added to a previously empty event queue, ASAP schedules a flush event, preferring for that event to occur before the JavaScript engine has an opportunity to perform IO tasks or rendering, thus making the first task and subsequent tasks semantically indistinguishable. ASAP uses a variety of techniques to preserve this invariant on different versions of browsers and Node.js. By design, ASAP prevents input events from being handled until the task queue is empty. If the process is busy enough, this may cause incoming connection requests to be dropped, and may cause existing connections to inform the sender to reduce the transmission rate or stall. ASAP allows this on the theory that, if there is enough work to do, there is no sense in looking for trouble. As a consequence, ASAP can interfere with smooth animation. If your task should be tied to the rendering loop, consider using requestAnimationFrame instead. A long sequence of tasks can also effect the long running script dialog. If this is a problem, you may be able to use ASAP’s cousin setImmediate to break long processes into shorter intervals and periodically allow the browser to breathe. setImmediate will yield for IO, reflow, and repaint events. It also returns a handler and can be canceled. For a setImmediate shim, consider YuzuJS setImmediate. Take care. ASAP can sustain infinite recursive calls without warning. It will not halt from a stack overflow, and it will not consume unbounded memory. This is behaviorally equivalent to an infinite loop. Just as with infinite loops, you can monitor a Node.js process for this behavior with a heart-beat signal. As with infinite loops, a very small amount of caution goes a long way to avoiding problems. In browsers, if a task throws an exception, it will not interrupt the flushing of high-priority tasks. The exception will be postponed to a later, low-priority event to avoid slow-downs. In Node.js, if a task throws an exception, ASAP will resume flushing only if—and only after—the error is handled by domain.on("error") or process.on("uncaughtException").

            I am starting with Firebase and want to know what are the most effective ways to structure data

            Let's take the example of a simple social media app where only photos can be shared (like the beginnings of Instagram).

            1. user upload a photo with some meta data (Description)

            2. (Home Feed) the users (followers) will see the post in a chronological way and offcource there will be other functionality like (liking the post , saving it , commenting)

            3. searching and following users

            4. notification about likes and comments

            5. search in comments

            Why is c# creating a file before any file stream is created?
            Asked 2022-Feb-03 at 22:06

            Background:
            I am creating an avaloniaUI project and in it I have a json config with a class that serializes and deserializes it on initialization and editing. If the file can't be found on initialization the class makes a new one with a list of default properties. This class is supposed to be the only part of the code that can do that.

            Problem:
            For some reason the config file, when it does not exist already, is created before the constructor call of the config serializer class. That lead my friends and I to think that the file was being created somewhere else in the project. That can't be the case though because I've used a control f tool to comb the entire project for references of any filestreams, create commands, or a reference to the config path and I found nothing else that's capable of generating a file other than the code that's supposed to create the config but never runs. So what happens is the file is created empty before the code that's supposed to handle generation is called thus skipping the proper generation code which leads to json loading an empty string when the file is deserialized and it creates null value exceptions.

            In my small tests tracing your code, it appears the problem lies in the SaveConfig() method. Walking through the code should reveal that the line of code… sw.Write(data); … is executing, however, nothing is actually written to the file. Adding a Flush statement for the StreamWriter should ensure that… sw.Write(data); … gets done. Adding the Flush() command to the writer appears to actually write the data to the file.
