Building and deploying an in-store digital signage solution
Dru was able to come in and immediately be productive.Tim Barcz
An existing digital signage solution was experiencing long outages, and and multiple bugs. This application is prominantely displayed in stores on screens ranging from 55” to 98” in size.
The real work for this project was to stabalize the application. So that it would work reliably. Once I was given access to the source code, I started to hunt down the problem. The issue ended up being centered on a common JavaScript issue where a member’s name had changed and was causing an issue in a recursive function. Because it was in this function, the issue wasn’t immediately apparent.
[!INFO] Another team had tried to take over the project but stated that it needed to be completely re-written in order to achieve the goals of stability and modernization. As some one who loves a good brownfield application, I was hired to do those things without the immediate re-write.
This was an older system that had been through three different “generations” of JavaScript / Node - after stabilizing the current iteration of the application, I worked on bringing the code base “up-to-code”. Overtime, systems will experience bit-rot as technology marches on. By deliberately targeting each change I was able to modernize the code base while reacting to new bugs identified by the applications increased usage.
async/await rather than a convoluted nest of for loops with recursive functions
