    • As we step into the exciting opportunities of August, we are at a crucial point in the ever-changing world of technology. Our adventure until now has been incredibly thrilling, with a strong focus on 'LLM in Production.' Now, we shift our attention to a topic that is always important and never outdated: Fullstack Engineering.

    In a world where new businesses and product teams are always changing, there is a high demand for engineers who are skilled in many areas and can handle both sides of the development process. The rise of AI-powered development tools has blurred the lines between front-end and back-end development, making it essential for engineers to know a wide range of technologies and methods.

    Type-safe Server Client Development

    Assess

    Developers working on Javascript Applications often face the challenge of enforcing type safety between the client and server. One effective solution is to automatically generate an OpenAPI Spec file from server code. This can then be used with the OpenAPI generator to produce a client-side library for making Type-safe API calls to the backend. Our existing workflow has adopted the Type-safe approach using Swagger for API documentation. We aim to upgrade this approach by automating the generation of API methods.

    Large language models

    Trial

    Our journey with Large language models continues to evolve. We are extending our research and learning path for engineers starting out in developing AI, as outlined in this Engineering Story Map for LLMs. Although each engineering story is unique, this map provides a general idea of where one might be in their journey and what lies ahead. We also had a successful experiment with Reinforcement Learning from Human Feedback (RLHF), despite realizing the challenges in the process of training and fine-tuning models in terms of handling operational, data, and lack of foundational knowledge. More details on the challenges faced can be found in this article.

    PNPM

    Adopt

    Our team has officially decided to switch to pnpm as our primary package management tool. After careful evaluation, we found that pnpm is widely embraced by the development community and has been successfully used by great teams at Vercel, Nx, and Chakra UI. Previously, we were using Yarn V1 classic, but as our projects grew, we faced challenges with disk space and slow installations. To streamline our development workflow, we explored pnpm and conducted thorough tests. The results were promising, proving pnpm to be efficient and reliable. Now, we have successfully migrated all major internal tools to pnpm, and it's already making a positive impact on our development speed and productivity. We've also started incorporating pnpm into some client projects. Though we encountered some difficulties with hoisted dependencies in monorepos during the migration process, the overall effort was worthwhile, contributing to our team's enhanced efficiency.

    Qwik

    Assess

    The developer world is flooded with numerous frameworks. NextJS, a comprehensive ecosystem and the reference implementation of React, has extensive libraries, documentation, and resources, aspects not paralleled by Qwik. This makes us skeptical about using Qwik for critical projects in the foreseeable future. However, Qwik's methodology could represent the future of development. It is crucial to understand Qwik's architecture, efficiency secrets, and coding technique implications. One key concept is Resumability, which refers to the ability of Qwik applications to resume from a server-side-rendered (SSR) state without the need for hydration. It's not about adopting Qwik entirely, but recognizing its potential influence on stalwarts like React and NextJS. Familiarity with Qwik can provide a pioneering advantage and a fresh perspective on framework dynamics.

    AI-aided development

    Assess

    In the software industry, the exploration of rapidly evolving AI tools for code writing support is becoming increasingly common. One compelling use-case is leveraging ChatGPT to generate tests for existing implementations, or even adopting a Test-Driven Development (TTD) approach where the AI drafts the tests before we implement the details. Beyond testing, our engineers have successfully utilized GPT models to generate Entity-Relationship Diagrams (ERDs) and various UML diagrams, with promising results. While we've experimented with AI for auditing source code, this remains a work-in-progress due to security concerns. Additionally, Copilot has become an invaluable tool in our development workflow, offering next-level autocompletion features that significantly enhance productivity.
