Zach Daniel, co-author of 'Building Web Applications with Ash' and creator of the Ash framework, joins Rebecca Le for a deep dive into the evolving landscape of Elixir programming. They explore the motivations behind Ash, recent improvements in version 3.0, and the crucial role of user feedback in shaping its features. The duo also discusses the upcoming Igniter tool and its impact on collaborative code generation, as well as the anticipated Ash 4.0 and its compatibility strategies, making programming more efficient and secure.
Ash 3.0 introduces significant updates that enhance security and user experience, facilitating easier transitions from previous versions for developers.
The integrated policy system in Ash allows for precise control over data accessibility based on user roles, enhancing overall data security.
The forthcoming book on Ash aims to provide a comprehensive tutorial, bridging the complexities of the framework for improved developer onboarding and understanding.
Deep dives
Introduction of Ash 3.0
The podcast discusses the significant updates in Ash 3.0, highlighting its upgraded functionality and improved user experience. Ash 3.0 has introduced changes that simplify the upgrade process for users transitioning from version 2.0, with many finding the ordeal manageable within a few days. Key modifications include tightening security defaults by making certain parameters private instead of public, enhancing the framework's overall safety and clarity. The new version has been designed to reduce common pitfalls, making it a more robust and reliable tool for developers.
The Role of Policies in Ash
A critical insight shared in the episode is the powerful policy system integrated within Ash, particularly the field policies that dictate access to specific data based on user roles. This system can restrict visibility of fields, such as a user's email address, so that non-admin users see only their own information. Additionally, it smartly prevents unauthorized data access during filtering processes, ensuring that users are not exposed to sensitive information they should not see. This capability strengthens the framework by providing granular control over data accessibility, something many frameworks struggle to implement effectively.
Introduction of Igniter for Streamlined Development
The hosts introduce Igniter, a tool designed to enhance the developer experience by simplifying code generation and modification processes. Igniter allows users to run commands that automatically patch source code, promoting efficiency in managing dependencies and generating new applications. One notable feature of Igniter is its ability to initiate an installation process for Ash and its dependencies using a simple command line interface, which can significantly ease the onboarding experience for new projects. This level of automation reduces the complexity often associated with managing multiple dependencies and configuring settings by hand.
Anticipation for the New Ash Book
The speakers reveal plans for a new book focused on building web applications using Ash, with a goal to guide developers through constructing a LiveView app step-by-step. The book will serve as both a reference and hands-on tutorial, covering essential topics such as resources, relationships, and authentication. This initiative stems from the authors' desire to improve developer onboarding and to clarify user experiences in utilizing Ash effectively. The book aims to wrap all of Ash's complexities within a structured framework that developers can easily navigate and understand.
Expert Insights into Framework Comparison
The discussion touches on how Ash compares to other frameworks, especially in terms of power and flexibility. While it possesses a steeper learning curve than Rails, Ash provides greater control and customization options, allowing developers to tailor their applications more finely than they could with standard CRUD frameworks. The hosts dissect common misconceptions about Ash being merely a quick API-building tool, emphasizing its comprehensive capabilities that manage complex application requirements efficiently. This interplay of flexibility versus complexity presents a fulcrum for developers when choosing the right framework for their specific needs.
In this conversation, Lars, Zach, and Rebecca discuss the Ash framework and their upcoming book. They also touch on the Igniter tool. The book, titled 'Building Web Applications with Ash', will provide a comprehensive tutorial and reference for using Ash and is expected in beta by the end of the year with @pragprog
