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

Grabby

NPM Build Status

Features

  • request compatibility
  • promise interface
  • encoding detection(utf8, win1251)
  • compressing detection(gzip, deflate)
  • debug support

Install

npm install grabby --save

Nice and fancy

var grabby = require('grabby');

// same as original node request
var request = {url: 'http://yandex.ru'};

// returns Promise
grabby.requestHtml(request).then(function (html) {
    // for example parse http with cheerio
    var $ = cheerio.load(html);
});

Advanced usage

var grabby = require('grabby');

// set fail reason and grabby will continue to try
// useful if you meet nginx with request per minute limit
grabby.requestHtml({
    url: '',
    attempt: {
        reason: [409], // status code
        reason: function (error, response) { // or your own reason
            /* check response */
        },
        delay: 100, // constant in ms
        delay: function (n) { // or even your custom value
            return 100 * n;
        },
        limit: 10 // reject promise after 10 tries
    }
});

Debug support

Debug mode is provided through the use of the debug module. To enable:

DEBUG=grabby node your_program.js

or even in your script

// set debug environment
process.env['debug'] = 'grabby';

Read the debug module documentation for more details.
