instagram-node - NodeJS driver for the instagram API

  •    Javascript

Instagram uses the standard oauth authentication flow in order to allow apps to act on a user's behalf. Therefore, the API provides two convenience methods to help you authenticate your users. The first, get_authorization_url, can be used to redirect an unauthenticated user to the instagram login screen based on a redirect_uri string and an optional options object containing an optional scope array and an optional state string. The second method, authorize_user, can be used to retrieve and set an access token for a user, allowing your app to act fully on his/her behalf. This method takes three parameters: a response_code which is sent as a GET parameter once a user has authorized your app and instagram has redirected them back to your authorization redirect URI, a redirect_uri which is the same one supplied to get_authorization_url, and a callback that takes two parameters err and result. err will be populated if and only if the request to authenticate the user has failed for some reason. Otherwise, it will be null and response will be populated with a JSON object representing Instagram's confirmation reponse that the user is indeed authorized. See instagram's authentication documentation for more information. Below is an example of how one might authenticate a user within an ExpressJS app.

node-vasync - utilities for observable asynchronous control flow

  •    Javascript

This module provides several functions for asynchronous control flow. There are many modules that do this already (notably async.js). This one's claim to fame is improved debuggability.But these structures also introduce new types of programming errors: failing to invoke the callback can cause the program to hang, and inadvertently invoking it twice can cause all kinds of mayhem that's very difficult to debug.

Jepsen - A framework for distributed systems verification, with fault injection

  •    Clojure

Jepsen is a Clojure library. A test is a Clojure program which uses the Jepsen library to set up a distributed system, run a bunch of operations against that system, and verify that the history of those operations makes sense. Jepsen has been used to verify everything from eventually-consistent commutative databases to linearizable coordination systems to distributed task schedulers. It can also generate graphs of performance and availability, helping you characterize how a system responds to different faults.

zone - Flow control and error handling for Node.js

  •    Javascript

NOTE: This project is deprecated and no longer being actively developed or maintained. See Issue #50 for details.The Zone library provides a way to represent the dynamic extent of asynchronous calls in Node. Just like the scope of a function defines where it may be used, the extent of a call represents the lifetime that is it active.

line-reader - Asynchronous line-by-line file reader for node.js

  •    Javascript

Asynchronous, buffered, line-by-line file/stream reader with support for user-defined line separators. The eachLine function reads each line of the given file. Upon each new line, the given callback function is called with two parameters: the line read and a boolean value specifying whether the line read was the last line of the file. If the callback returns false, reading will stop and the file will be closed.

If desired, initial data for the spreadsheet can be passed in as an array of rows. In addition, you can pass in a second array filled with class names for each cell, allowing you to style each cell differently.

continuation - A compiler for JavaScript asynchronous Continuation-Passing Style transformation

  •    Javascript

Continuation.js is a compiler for Continuation-Passing Style transformation, which simplifies asynchronous JavaScript programming. It translates slightly flavored JavaScript syntax into standard JavaScript, so it can be also called a "translator". Continuation.js introduces a virtual function cont, which allow you to write continuation-passing style code (or asynchronous callback style code) far easier. cont is not a actual function, but a mark with the same syntax to function calls in JavaScript. By using Continuation.js you can write asynchronous control flows like flat threaded code, and it compiles it into continuation-passing style code. The code above is flatted by using the virtual function cont. Control flow must "wait" for the return of asynchronous function call fs.readFile. Parameters in the argument list of cont will be set after it returns. "Return" here is a little confusing because in an asynchronous function "return" means callback function called, not "return" in the literal sense. An asynchronous function usually returns immediately (by encountering return statement or the end of the function scope) while the callback function could be called later. You can be understood as all the statements after cont until the end of the function are the callback function of the asynchronous function call. The code feels like threaded code, but it is still asynchronous while executing.

array-explorer - ⚡️ A resource to help figure out what JavaScript array method would be best to use at any given time

  •    Javascript

When I was first learning array methods, I spent a lot of time digging through the docs to find the appropriate one, and I had to search one by one. I made this resource to help people find the correct array method a bit more naturally. You can narrow down what you want to do and explore until you find what's most useful to you. I realize that there are about a million ways that this resource can be set up, and some of the taxonomy is necessarily opionionated. I tried to focus on what I thought would have helped me learn the best, rather than industry standard delineations (mutator, accessor, iteration, for example). There are a lot of resources that already divide the methods this way, so if that style of learning suits you better, that's great! This resource is not set up that way. Please keep in mind that this is not meant to be as comprehensive or a replacement for full documentation, which is why the MDN docs are linked to in each method.

party-mode - An experimental music visualizer using d3.js and the web audio api.

  •    Javascript

Using the web audio api, I can get an array of numbers which corresponds to the waveform of the sound an html5 audio element is producing. There's a good tutorial on how to do this. Then, using requestAnimationFrame (with a little frame limiting for performance reasons) I'm updating that array as the music changes. I then normalize the data a bit (or transform it slightly depending on the visualization) and redraw the screen based on the updated array. I'm using d3.js to draw and redraw SVG based on this normalized data. Each visualization uses the data a bit differently -- it was mostly trial and error to get some stuff I liked looking at. Since I'm using D3 -- which is just drawing SVG -- I was able to style everything in CSS (no images are used at all, including icons). There are a handful of differently colored themes for each visualization, and I do some rudimentary CSS namespacing by updating a class applied to the html element. eg. <html class='theme_1'>. This lets me override or substitute CSS rules pretty trivially. I can add some additional variation to each theme by messing with pseudo selectors. For example, I can use :nth-of-type to hide every nth SVG rectangle or making every odd child have a different stroke-dasharray, etc.
