[ScalaDaysNewYork2016] Domain-Driven Design and Onion Architecture in Scala
Wade Waldron, a senior consultant at Lightbend and co-author of Applied Akka Patterns, presented a compelling case for combining Domain-Driven Design (DDD) and Onion Architecture at Scala Days New York 2016. Using the relatable example of frying an egg, Wade illustrated how these methodologies enhance code clarity, maintainability, and portability, leveraging Scala’s expressive features to model complex domains effectively.
Defining the Core Domain
Wade Waldron introduced DDD as a methodology that prioritizes the core domain—the sphere of knowledge central to a system—over peripheral concerns like user interfaces or databases. Using the egg-frying case study, Wade demonstrated how Scala’s case classes and traits enable rapid prototyping of domain models, such as eggs, frying pans, and cooking processes. By focusing on domain rules rather than technology, developers can create stable, reusable code. Wade emphasized that DDD does not require CQRS or event sourcing, though these patterns complement it, allowing flexibility in implementation.
Leveraging Onion Architecture
Onion Architecture, Wade explained, organizes code into concentric layers, with the domain model at the core and infrastructure, like databases, at the outer layers. This structure ensures portability by isolating the domain from external dependencies. In the egg-frying example, repositories and services abstract interactions with external systems, allowing seamless swaps of databases or APIs without altering the core logic. Wade showcased how Scala’s concise syntax supports this layering, enabling developers to maintain clean package structures and focus on business logic.
Enhancing Portability and Testability
A key benefit of combining DDD with Onion Architecture, as Wade highlighted, is the ability to refactor implementations without impacting consumers. By defining clear APIs and using repositories, developers can switch databases or rewrite domain models transparently. Wade shared real-world examples where his team performed live migrations and database swaps unnoticed by users, thanks to the abstraction layers. This approach also simplifies testing, as in-memory repositories can mimic real data stores, enhancing test efficiency and reliability.
Engaging Stakeholders with Domain Language
Wade stressed the importance of using a ubiquitous language in DDD to align developers and stakeholders. In the egg-frying scenario, terms like “fry” and “cook” bridge technical and non-technical discussions, ensuring clarity. However, Wade acknowledged challenges in large organizations where stakeholders may focus on technical details. He advised persistently steering conversations back to the domain level, fostering a shared understanding that drives effective collaboration and reduces miscommunication.

[DevoxxFR] Kill Your Branches, Do Feature Toggles
For many software development teams, managing feature branches in version control can be a source of significant pain and delays, particularly when branches diverge over long periods, leading to complex and time-consuming merge conflicts. Morgan LEROI proposed an alternative strategy: minimize or eliminate long-lived feature branches in favor of using Feature Toggles. His presentation explored the concepts behind feature toggles, their benefits, and shared practical experience on how this approach can streamline development workflows and enable new capabilities like activating features on demand.
Morgan opened by illustrating the common frustration associated with merging branches that have diverged significantly, describing it as a “traumatic experience”. This pain point underscores the need for development practices that reduce the time code spends in isolation before being integrated.
Embracing Feature Toggles
Feature Toggles, also known as Feature Flags, are a technique that allows developers to enable or disable specific features in an application at runtime, without deploying new code. The core idea is to merge code frequently into the main development branch (e.g., main or master), even if features are not yet complete or ready for production release. The incomplete or experimental features are wrapped in toggles that can be controlled externally.
Morgan explained that this approach addresses the merge hell problem by ensuring code is integrated continuously in small increments, minimizing divergence. It also decouples deployment from release; code containing new features can be deployed to production disabled, and the feature can be “released” or activated later via the toggle when ready.
Practical Benefits and Use Cases
Beyond simplifying merging, Feature Toggles offer several tangible benefits. Morgan highlighted their use by major industry players, including Amazon, demonstrating their effectiveness at scale. A key advantage is the ability to activate new features on demand, for specific user groups, or even for individual users. This enables phased rollouts, A/B testing, and easier rollback if a feature proves problematic.
Morgan detailed the application of feature toggles in A/B testing scenarios. By showing different versions of a feature (or the presence/absence of a feature) to different user segments, teams can collect metrics on user behavior and make data-driven decisions about which version is more effective. This allows for continuous experimentation and optimization based on real-world usage. He suggested that even a simple boolean configuration toggle (if (featureIsEnabled) { ... }) can be a starting point. Morgan encouraged developers to consider feature toggles as a powerful tool for improving development flow, reducing merge pain, and gaining flexibility in releasing new functionality. He challenged attendees to reflect on whether their current branching strategy is serving them well and to consider experimenting with feature toggles. Morgan Leroi is a Staff Software Engineer at Algolia.

[DevoxxFR] An Ultrasonic Adventure!
In the quest for novel ways to enable communication between web pages running on different machines without relying on a central server, Hubert SABLONNIERE embarked on a truly unique and fascinating experiment: using ultrasonic sound emitted and received through web browsers. This adventurous project leveraged modern web audio capabilities to explore an unconventional method of initiating a peer-to-peer connection, pushing the boundaries of what’s possible with web technologies.
Hubert’s journey began with a seemingly simple question that led down an unexpected path. The idea was to use audible (or in this case, inaudible) sound as a signaling mechanism to bootstrap a WebRTC connection, a technology that allows direct browser-to-browser communication.
Signaling with Ultrasound
The core concept involved using the Web Audio API to generate audio signals at frequencies beyond the range of human hearing – ultrasounds. These signals would carry encoded information, acting as a handshake or discovery mechanism. A web page on one machine would emit these ultrasonic signals through the computer’s speakers, and a web page on another nearby machine would attempt to detect and decode them using the Web Audio API and the computer’s microphone.
Once the two pages successfully exchanged the necessary information via ultrasound (such as network addresses or session descriptions), they could then establish a direct WebRTC connection for more robust and higher-bandwidth communication. Hubert’s experiment demonstrated the technical feasibility of this imaginative approach, turning computers into acoustic modems for web pages.
Experimentation and Learning
Hubert emphasized that the project was primarily an “adventure” and an excellent vehicle for learning, rather than necessarily a production-ready solution. Building this ultrasonic communication system provided invaluable hands-on experience with several cutting-edge web technologies, specifically the Web Audio API for generating and analyzing audio and the WebRTC API for peer-to-peer networking.
Personal projects like this, free from the constraints and requirements of production environments, offer a unique opportunity to explore unconventional ideas and deepen understanding of underlying technologies. Hubert shared that the experiment, developed over several nights, allowed him to rapidly learn and experiment with WebRTC and Web Audio in a practical context. While the real-world applicability of using ultrasound for web page communication might be limited by factors like ambient noise, distance, and device microphone/speaker capabilities, the project served as a powerful illustration of creative problem-solving and the potential for unexpected uses of web APIs. Hubert made the project code available on GitHub, encouraging others to explore this ultrasonic frontier and potentially build upon his adventurous experimentation.
