DWS releases open source library to revolutionise app development

Code-named “Muster”, the library acts as a universal data layer for applications and services. Within DWS, the code is used by our external & internal web, iOS and Android apps, such as DWS Investment app launched this year. It enables fast retrieval of all information required by the DWS Investment app, running on Android or iOS devices.

Because the code is publicly available, developers can suggest improvements, contribute new features and find innovative new uses for the software. This is fed back into the open source community making the application even more useful for everyone. The move to release the code into the open source community underpins DWS’s digital ambitions, particularly as it aims to modernise, simplify and standardise its technology.

As Adam Iley, Head of Development & Emerging Technology at DWS, explains, Muster offers unparalleled flexibility when managing client-side state and data requirements, and seamlessly handles communication between apps and external services. “The innovative query language minimises data transfer, latency and concurrent requests – all especially vital for mobile applications, where bandwidth is restricted and variable,” he says. Iley adds: “Muster has been a huge boon for our web and native applications. I’m excited to see what the community will do with it.”

The code can be accessed via the GitHub platform.
