Deprecating buggy npm packages, dealing with deprecations It seems several critical npm packages deprecated older releases. Installing the old version of some packages causes npm to print a warning saying the package was deprecated, and to use a newer version of the package. Sometimes the message suggests a way to figure out where the package is being required. Due to the way an npm package can pull in other npm packages, it can be tricky to figure out where the deprecated package version is being used.
Easily import your CSV data into MySQL with Node.js

It's convenient to import a CSV file into a spreadsheet to crunch numbers. CSV's (comma-seperated-values) and it's brethren (TSV, for tab-separated, etc) are widely used to deliver information. You'll see CSV downloads available all over the place, whether it's your stock broker or bank, or a government agency, and on and on. Spreadsheet programs like LibreOffice Calc offer direct import of these files, and then as a spreadsheet you've got a zillion tools available to crunch numbers, make graphs, etc. Sometimes, though, you need to load the CSV into a database to do other sorts of work.

How do function(err,data) callbacks work in Node? Those new to Node programming might find the callback function pattern a little difficult to understand.  For example how does the data get into the arguments to the function call, and how does the callback function get called?
Is Node.js / Express scalable? How to grow Node.js app deployment to handle more traffic? Since Node.js is billed as being very fast, high performance, application development platform, you might think it automatically "scales" to fill out server resources and satisfy a huge workload. While you can do this with a Node.js application, you have to design the scaling mechanism yourself. With no additional configuration, a Node.js application can saturate a single CPU core and handle as many transactions as that core can sustain. That doesn't help when your manager asks why that 32 core server you just ordered has 31 idle CPU cores and one running flat out. Out of the box Node.js doesn't scale, but it's possible to make it do so.
Make your own Raspberry Pi git repository server with Gogs and Docker The Raspberry Pi is an amazing little computer that, while it's targeted at the DIY Hardware Maker, it is a full-fledged Linux computer that can be used to run services that used to require much bigger and more expensive computers. How long ago were office servers required to be $4000 systems from the likes of Dell Computers? It seems that the Raspberry Pi (and other tiny computers) can perform the same tasks at a low cost with minuscule energy requirements. To this end I'm setting up Gogs (a github-like server for Git repositories) on a Raspberry Pi. As I worked on the project it seemed most straightforward to use Docker to manage the Gogs process, and therefore the project became setting up Docker on Raspberry Pi to run other services.
New Book: Asynchronous JavaScript with Promises, Generators and async/await The JavaScript language is changing, and among the changes are three new features which will revolutionize the way we write asynchronous code in JavaScript. The problem with the old callback-oriented asynchronous coding practice is the Callback Hell resulting from stacking callbacks within callbacks within callbacks. Between Promises, Generators and the proposed async/await feature, JavaScript programmers can largely free themselves from Callback Hell, and write clean asynchronous code that's easier to write, easier to understand, easier to maintain, and more robust.
