[DevoxxBE2023] Build a Generative AI App in Project IDX and Firebase by Prakhar Srivastav
At Devoxx Belgium 2023, Prakhar Srivastav, a software engineer at Google, unveiled the power of Project IDX and Firebase in crafting a generative AI mobile application. His session illuminated how developers can harness these tools to streamline full-stack, multiplatform app development directly from the browser, eliminating cumbersome local setups. Through a live demonstration, Prakhar showcased the creation of “Listed,” a Flutter-based app that leverages Google’s PaLM API to break down user-defined goals into actionable subtasks, offering a practical tool for task management. His engaging presentation, enriched with real-time coding, highlighted the synergy of cloud-based development environments and AI-driven solutions.
Introducing Project IDX: A Cloud-Based Development Revolution
Prakhar introduced Project IDX as a transformative cloud-based development environment designed to simplify the creation of multiplatform applications. Unlike traditional setups requiring hefty binaries like Xcode or Android Studio, Project IDX enables developers to work entirely in the browser. Prakhar demonstrated this by running Android and iOS emulators side-by-side within the browser, showcasing a Flutter app that compiles to multiple platforms—Android, iOS, web, Linux, and macOS—from a single codebase. This eliminates the need for platform-specific configurations, making development accessible even on lightweight devices like Chromebooks.
The live demo featured “Listed,” a mobile app where users input a goal, such as preparing for a tech talk, and receive AI-generated subtasks and tips. For instance, entering “give a tech talk at a conference” yielded steps like choosing a relevant topic and practicing the presentation, with a tip to have a backup plan for technical issues. Prakhar’s real-time tweak—changing the app’s color scheme from green to red—illustrated the iterative development flow, where changes are instantly reflected in the emulator, enhancing productivity and experimentation.
Harnessing the PaLM API for Generative AI
Central to the app’s functionality is Google’s PaLM API, which Prakhar utilized to integrate generative AI capabilities. He explained that large language models (LLMs), like those powering the PaLM API, act as sophisticated autocomplete systems, predicting likely text outputs based on extensive training data. For “Listed,” the text API was chosen for its suitability in single-turn interactions, such as generating subtasks from a user’s query. Prakhar emphasized the importance of crafting effective prompts, comparing a vague prompt like “the sky is” to a precise one like “complete the sentence: the sky is,” which yields more relevant results.
To enhance the AI’s output, Prakhar employed few-shot prompting, providing the model with examples of desired responses. For instance, for the query “go camping,” the prompt included sample subtasks like choosing a campsite and packing meals, along with a tip about wildlife safety. This structured approach ensured the model generated contextually accurate and actionable suggestions, making the app intuitive for users tackling complex tasks.
Securing AI Integration with Firebase Extensions
Integrating the PaLM API into a mobile app poses security challenges, particularly around API key exposure. Prakhar addressed this by leveraging Firebase Extensions, which provide pre-packaged solutions to streamline backend integration. Specifically, he used a Firebase Extension to securely call the PaLM API via Cloud Functions, avoiding the need to embed sensitive API keys in the client-side Flutter app. This setup not only enhances security but also simplifies infrastructure management, as the extension handles logging, monitoring, and optional AppCheck for client verification.
In the live demo, Prakhar navigated the Firebase Extensions Marketplace, selecting the “Call PaLM API Securely” extension. With a few clicks, he deployed Cloud Functions that exposed a POST API for sending prompts and receiving AI-generated responses. The code walkthrough revealed a straightforward implementation in Dart, where the app constructs a JSON payload with the prompt, model name (text-bison-001), and temperature (0.25 for deterministic outputs), ensuring seamless and secure communication with the backend.
Building the Flutter App: Simplicity and Collaboration
The Flutter app’s architecture, built within Project IDX, was designed for simplicity and collaboration. Prakhar walked through the main.dart file, which scaffolds the app’s UI with a material-themed interface, an input field for user queries, and a list to display AI-generated tasks. The app uses anonymous Firebase authentication to secure backend calls without requiring user logins, enhancing accessibility. A PromptBuilder class dynamically constructs prompts by combining predefined prefixes and examples, ensuring flexibility in handling varied user inputs.
Project IDX’s integration with Visual Studio Code’s open-source framework added collaborative features. Prakhar demonstrated how developers can invite colleagues to a shared workspace, enabling real-time collaboration. Additionally, the IDE’s AI capabilities allow users to explain selected code or generate new snippets, streamlining development. For instance, selecting the PromptBuilder class and requesting an explanation provided detailed insights into its parameters, showcasing how Project IDX enhances developer productivity.

Lecturer
Ken Walker, a seasoned software engineer at IBM in Ottawa, Canada, leads the Orion project at the Eclipse Foundation. With extensive experience in software tooling, Walker has been instrumental in advancing web-based development environments. His work focuses on bridging the gap between traditional desktop IDEs and emerging cloud-based solutions, emphasizing accessibility and collaboration. As a key contributor to the Eclipse ecosystem, he leverages IBM’s long-standing involvement in open-source initiatives, including the Eclipse Foundation’s formation in 2004, to drive innovation in developer tools.
Abstract
The transition to cloud-based development environments has promised seamless collaboration, instant access, and reduced setup overhead, yet browser-based Integrated Development Environments (IDEs) like Orion face skepticism from developers accustomed to robust desktop tools such as IntelliJ IDEA or Visual Studio. This lecture, delivered at Devoxx France 2014, explores the reasons behind this resistance, dissecting the technical and usability shortcomings of browser IDEs while highlighting their unique strengths. Through a detailed comparison of desktop and cloud-based development workflows, Ken Walker examines performance bottlenecks, integration challenges, and user experience gaps that deter adoption. He also showcases Orion’s innovative features, such as real-time collaboration and cloud deployment integration, to demonstrate its potential. The discussion concludes with a forward-looking perspective on how evolving web technologies could make browser IDEs indispensable, offering insights for developers considering hybrid workflows in modern software engineering.
The Evolution of IDEs and the Cloud Paradigm Shift
Integrated Development Environments have evolved significantly since the 1980s, when tools like Turbo Pascal provided basic editing and compilation for single languages. The 1990s introduced cross-platform IDEs like Eclipse and NetBeans, which embraced modular architectures to support diverse languages and tools. These desktop IDEs excelled in performance, leveraging local hardware for fast code completion, debugging, and refactoring. However, the rise of cloud computing in the late 2000s sparked a shift toward browser-based IDEs, promising accessibility across devices, automatic updates, and collaborative features akin to Google Docs.
Ken Walker highlights that this shift has not been universally embraced. Developers often find browser IDEs lacking in responsiveness, particularly for tasks like code analysis or large-scale refactoring. This stems from browser sandboxing, which restricts access to local resources, and the inherent limitations of JavaScript execution compared to native applications. For instance, real-time syntax highlighting in a browser IDE may lag when processing thousands of lines, whereas desktop tools like IntelliJ leverage multithreading and local caching for near-instantaneous feedback.
Integration with local development environments poses another challenge. Desktop IDEs seamlessly interact with local file systems, Git clients, and build tools like Maven. In contrast, browser IDEs rely on cloud storage or WebSocket-based synchronization, which can introduce latency or data consistency issues during network disruptions. Walker cites user feedback from the Eclipse community, noting that developers often struggle with configuring browser IDEs to replicate the seamless toolchains of desktop counterparts.
Why Developers Resist Browser IDEs
Walker delves into specific pain points that fuel developer skepticism. One major issue is the lack of feature parity with desktop IDEs. Advanced debugging, a cornerstone of development, is less robust in browser environments. For example, Orion’s debugging relies on remote sessions, which can falter over unstable connections, making it difficult to step through code or inspect complex object states. In contrast, tools like Visual Studio offer graphical debuggers with real-time memory visualization, which browser IDEs struggle to replicate due to browser API constraints.
User experience gaps further compound resistance. Keyboard shortcuts, critical for productivity, often conflict with browser defaults (e.g., Ctrl+S for saving vs. browser save-page functionality), requiring developers to relearn bindings or configure overrides, which vary across browsers like Chrome, Firefox, and Safari. Touch-based devices exacerbate usability issues, as precise cursor placement or multi-line editing becomes cumbersome without mouse input, particularly on tablets.
Collaboration, a touted benefit of browser IDEs, can also disappoint. While real-time editing is possible, poorly handled concurrent changes lead to merge conflicts, especially in large teams. Orion’s Git integration supports basic workflows like commits and pulls, but complex operations like rebasing or resolving merge conflicts lack the intuitive interfaces of desktop tools. Walker acknowledges these issues but argues that they reflect growing pains rather than inherent flaws, as web technologies continue to mature.
Orion’s Strengths and Innovations
Despite these challenges, Orion offers compelling advantages that desktop IDEs struggle to match. Its cloud-native design enables instant project sharing: developers can fork a GitHub repository, edit code in the browser, and push changes without local setup. This lowers barriers for open-source contributors and simplifies onboarding for distributed teams. For example, a developer can share a workspace URL, allowing colleagues to edit code or review changes in real time, a feature that requires additional plugins in desktop IDEs.
Orion integrates seamlessly with cloud platforms like Heroku and AWS, enabling direct deployment from the browser. This streamlines workflows for web developers, who can preview applications without leaving the IDE. Walker demonstrates a live example where a JavaScript application is edited, tested, and deployed to a cloud server in under a minute, showcasing the potential for rapid prototyping.
Recent advancements in web technologies bolster Orion’s capabilities. WebAssembly enables computationally intensive tasks like code analysis to run efficiently in browsers, narrowing the performance gap with native tools. Service workers provide offline support, caching code to allow editing during network outages. Orion’s plugin architecture further enhances flexibility, allowing developers to add custom tools, such as live CSS previews or integration with CI/CD pipelines like Jenkins.
Comparing Desktop and Cloud Workflows
Desktop IDEs excel in performance and integration. IntelliJ IDEA, for instance, uses indexed codebases for instant autocomplete and refactoring across millions of lines. Local Git clients provide robust version control, and native debuggers offer granular control. However, these tools require significant setup—installing Java, configuring plugins, and ensuring compatibility across operating systems—which can hinder collaboration in distributed teams.
Browser IDEs prioritize accessibility. Orion requires only a browser, eliminating installation barriers and ensuring consistency across devices. For educational settings or hackathons, this is transformative: participants can start coding instantly without worrying about Java versions or environment variables. Walker cites Orion’s use in Eclipse community workshops, where novices and experts collaborate seamlessly on shared projects.
The trade-off lies in complexity. Desktop IDEs handle large, monolithic codebases better, while browser IDEs shine for web-focused or lightweight projects. Walker proposes a hybrid model: use browser IDEs for quick edits, prototyping, or collaborative tasks, and desktop IDEs for heavy-duty development like systems programming or enterprise applications.
Future Directions for Browser IDEs
Emerging web standards promise to address current limitations. WebGPU, for instance, will enable hardware-accelerated graphics, improving performance for tasks like code visualization. Progressive Web Apps (PWAs) enhance offline capabilities, making browser IDEs viable in low-connectivity environments. Integration with AI-driven tools, such as GitHub Copilot, could provide intelligent code suggestions, further closing the gap with desktop IDEs.
Walker envisions browser IDEs evolving into primary tools as browser performance approaches native levels. Projects like CodeSandbox and Replit, which emerged post-2014, validate this trajectory, offering robust cloud IDEs with growing adoption. Orion’s open-source nature ensures community-driven enhancements, with plugins for languages like Python and Go expanding its scope.
Conclusion: A Balanced Perspective on Cloud Development
Browser IDEs like Orion represent a paradigm shift, offering unmatched accessibility and collaboration but facing hurdles in performance and integration. While developer resistance is understandable given the maturity of desktop tools, rapid advancements in web technologies suggest a convergence of capabilities. By adopting a hybrid approach—leveraging browser IDEs for lightweight tasks and desktop IDEs for complex projects—developers can maximize productivity. Walker’s talk at DevoxxFR2014 underscores the potential for browser IDEs to reshape development, encouraging the audience to explore tools like Orion while acknowledging areas for improvement.
