Node.js the Right Way: Practical Server-Side JavaScript That Scales

By Jim R. Wilson
ISBN-13: 978-1937785734

Node.js the Right Way is a fantastic little book. It’s a small book (but then it’s Pragmatic exPress) and it doesn’t go into anything in much detail, but then that’s what makes it fantastic. It gives a useful and practical overview of writing Node.js server side applications and explains many of the tools and JavaScript patterns which will be useful to Node.js programmers.

It starts off with examples of manipulating the local file system using Node.js. This struck me a little odd as the only thing I tend to use the local file system for is reading configuration files. If I need to write a file I tend to put it in Amazon S3. However, this is genius and looking at how to manipulate the filesystem gives some useful insights into Node.js programming.

The book then goes on to look at networking with sockets, something which is often neglected in a world where we expect everything to be RESTful. There’s then a tour through scalable messaging, including clustering, how to access databases and how to write web services, including JavaScript promises and generators!

The final chapter covers writing a web application with a single page front end and authentication. This is the only place the book falls down. Too much is covered in two short a chapter. It’s still quite useful though.

This is not a book for a novice JavaScript or even a novice Node.js developer, but for once a little knowledge is not a dangerous thing and Node.js the Right Way will help increase that knowledge. It even led me to believe JavaScript might actually be the future.

Write Your Own Load Balancer: A worked Example

I was out walking with a techie friend of mine I’d not seen for a while and he asked me if I’d written anything recently. I hadn’t, other than an article on data sharing a few months before and I realised I was missing it. Well, not the writing itself, but the end result. In the last few weeks, another friend of mine, John Cricket , has been setting weekly code challenges via linkedin and his new website, https://codingchallenges.fyi/ . They were all quite interesting, but one in particular on writing load balancers appealed, so I thought I’d kill two birds with one stone and write up a worked example. You’ll find my worked example below. The challenge itself is italics and voice is that of John Crickets. The Coding Challenge https://codingchallenges.fyi/challenges/challenge-load-balancer/ Write Your Own Load Balancer This challenge is to build your own application layer load balancer. A load balancer sits in front of a group of servers and routes client requests across all of the serv...

Catalina-Ant for Tomcat 7

I recently upgraded from Tomcat 6 to Tomcat 7 and all of my Ant deployment scripts stopped working. I eventually worked out why and made the necessary changes, but there doesn’t seem to be a complete description of how to use Catalina-Ant for Tomcat 7 on the web so I thought I'd write one. To start with, make sure Tomcat manager is configured for use by Catalina-Ant. Make sure that manager-script is included in the roles for one of the users in TOMCAT_HOME/conf/tomcat-users.xml . For example: <tomcat-users> <user name="admin" password="s3cr£t" roles="manager-gui, manager-script "/> </tomcat-users> Catalina-Ant for Tomcat 6 was encapsulated within a single JAR file. Catalina-Ant for Tomcat 7 requires four JAR files. One from TOMCAT_HOME/bin : tomcat-juli.jar and three from TOMCAT_HOME/lib: catalina-ant.jar tomcat-coyote.jar tomcat-util.jar There are at least three ways of making the JARs available to Ant: Copy the JARs into th...

RESTful Behaviour Guide

I’ve used a lot of existing Representational State Transfer (REST) APIs and have created several of my own. I see a lot of inconsistency, not just between REST APIs but often within a single REST API. I think most developers understand, at a high level, what a REST API is for and how it should work, but lack a detailed understanding. I think the first thing they forget to consider is that REST APIs allow you to identify and manipulate resources on the web. Here I want to look briefly at what a REST API is and offer some advice on how to structure one, how it should behave and what should be considered when building it. I know this isn’t emacs vs vi, but it can be quite contentious. So, as Barbossa from Pirates of the Caribbean said, this “...is more what you’d call ‘guidelines’ than actual rules.” Resources & Identifiers In their book, Rest in Practice - Hypermedia and Systems Architecture (‎ISBN: 978-0596805821), Jim Webber, Savas Parastatidis and Ian Robinson describe resour...
