Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

fake-async

Obsoleto

Este paquete fue creado para solventar ciertas necesidades específicas en su tiempo, sin embargo ahora se está reescribiendo vw, y se incluye dentro del core un completo runtime para ejecutar ECMAScript 6 y además ciertas funciones de ECMAScript 7 entre ellas: GeneratorFunction y Async/Await. También tendrá un soporte para Async Generators aunque aun no como parte de la sintáxis.

Por lo tanto se desaconseja el uso de fake-async

fake-async es un módulo creado para escribir código asíncrono de manera legible, y fácil de mantener

  • Evite múltiples niveles anidados cuando se programa con callbacks
  • Escriba código fácil de entender sin tener que bajar módulos que tienen que compilarse
  • Funciona sobre plataformas móviles con JxCore o vw

Installation independiente

$ npm install fake-async

Cómo usar

En CoffeeScript


async= (require "fake-async").create()
fs= require "fs"

## Para compilar en el mismo contexto es necesario colocar lo siguiente:
async.setevalfunction (str)->
    return eval str


f= async ()->
        try 
            dirs= await fs.readdir "/home"
            console.log dirs
            if dirs[0]
                dirs= await fs.readdir "/home/" + dirs[0]
                console.log dirs
        catch e
            console.log "Ocurrió un error"
            console.log e
            


f()

Escribir el código anterior sería equivalente a:


fs= require "fs"

f= ()->
	fs.readdir "/home", (err, dirs)->
            if err
                console.log "Ocurrió un error"
                console.log e
                return
            
            console.log dirs
            if dirs[0]
                fs.readdir "/home/" + dirs[0], (err, dirs)->
                    if err
                        console.log "Ocurrió un error"
                        console.log e
                        return
                    
                    console.log dirs
                
                
		

f()
