Codebase Refactoring (with help from Go)
1. Abstract Go should add the ability to create alternate equivalent names for types, in order to enable gradual code repair during codebase refactoring. This article explains the need for that ability and the implications of not having it for today’s large Go codebases. This article also examines some potential solutions, including the alias feature proposed during the development of (but not inc
bliki: IsOptimizationRefactoring
If you make a change to improve the performance of a program, is this a refactoring? I see optimization and refactoring as two separate things, even though they often use the same transformations, and a particular transformation you do to your program may be both. The reason I see them as different is because they have a different purpose. You do refactoring to make the code easier to understand,

Refactoring a JavaScript video store
The simple example of calculating and formatting a bill for a video store opened my refactoring book in 1999. If done in modern JavaScript, there are several directions you could take the refactoring. I explore four here: refactoring to top level functions, to a nested function with a dispatcher, using classes, and transformation using an intermediate data structure. 18 May 2016 Many years ago, wh
Refactoring Code to Load a Document
Much modern web server code talks to upstream services which return JSON data, do a little munging of that JSON data, and send it over to rich client web pages using fashionable single page application frameworks. Talking to people working with such systems I hear a fair bit of frustration of how much work they need to do to manipulate these JSON documents. Much of this frustration could be avoide
Refactoring to an Adaptive Model
Most of our software logic is written in our programming languages, these give us the best environment to write and evolve such logic. But there are circumstances when it's useful to move that logic into a data structure that our imperative code can interpret - what I refer to as an adaptive model. Here I'll show some product selection logic in JavaScript and show how it can be refactored to a sim
Refactoring Module Dependencies
As a program grows in size it's important to split it into modules, so that you don't need to understand all of it to make a small modification. Often these modules can be supplied by different teams and combined dynamically. In this refactoring essay I split a small program using Presentation-Domain-Data layering. I then refactor the dependencies between these modules to introduce the Service Loc
An example of preparatory refactoring
There are various ways in which refactoring can fit into our programming workflow. One useful notion is that of Preparatory Refactoring. This is where I'm adding a new feature, and I see that the existing code is not structured in such a way that makes adding the feature easy. So first I refactor the code into the structure that makes it easy to add the feature, or as Kent Beck pithily put it "mak
Natural Course of Refactoring – a Refactoring Workflow
The InfoQ Trends Reports 2023 eMag The InfoQ trends reports provide a snapshot of emerging software technology and ideas. We create the reports and accompanying graphs to aid software engineers and architects in evaluating what trends may help them design and build better software. Our editorial teams also use them to help focus our content on innovator and early adopter trends.
TDD: Where Did It All Go Wrong?
Sustainable Security Requirements with the ASVS Josh Grossman provides a brief overview of what the ASVS is, but takes a closer look at balancing trade-offs and prioritizing different security requirements. Josh shares how to make the process repeatable and how to implement it as part of your own organization's requirements process.
