The talk focuses on LinkedIn's journey to achieve zero lint failures in their extensive codebase, which includes over 24,000 files and 100k commits. They implemented linting in three stages: during development, pre-commit, and pre-merge, to ensure code consistency and bug prevention. LinkedIn faced significant challenges due to the large number of existing lint failures and the continuous introduction of new ones. To tackle these challenges, they introduced a rule that required fixing all existing errors before enabling a new lint rule. They also developed tools like Checkup, which visualizes ESLint failures by team and rule, providing accountability and responsibility. LinkedIn incentivized developers to address lint failures by offering technical support, shout-outs, and a better developer experience. This initiative led to a 30% increase in perceived code quality, with the cleanup of over 6,000 lint failures involving 55 contributors. The success of this initiative highlights the importance of linting tools and strategies in maintaining high code quality in large-scale codebases.

This talk explores the use of AI in web development, including tools like GitHub Copilot and Fig for CLI commands. AI can generate boilerplate code, provide context-aware solutions, and generate dummy data. It can also assist with CSS selectors and regexes, and be integrated into applications. AI is used to enhance the podcast experience by transcribing episodes and providing JSON data. The talk also discusses formatting AI output, crafting requests, and analyzing embeddings for similarity.

Setting up the system and separating concerns are important in software development. Modular construction and prefab units are a new trend that makes construction quicker and easier. Architectural complexity can lead to a drop in productivity and an increase in defects. Measuring architectural complexity can help identify natural modules in the code. Best practices for avoiding architectural complexity include organizing code by business domain and using prop drilling. Atomic design and organizing a monorepo are recommended approaches for managing architectural complexity.

This Talk explores the benefits of using TuberApple, a tool for supercharging the development experience. It highlights the advantages of monorepos, such as code reuse, shared standards, improved team collaboration, and atomic changes. TuberApple, specifically Tuburepo, offers efficient task execution through caching and optimized scheduling. It simplifies monorepo development by allowing parallel execution of tasks and seamless coordination of changes. Tubo, another tool within TuberApple, enables smart task execution, declaring task dependencies, and efficient caching in monorepos.

At Shopify scale, we solve some pretty hard problems. In this workshop, five different speakers will outline some of the challenges we’ve faced, and how we’ve overcome them.

Table of contents:
1 - The infamous "N+1" problem: Jonathan Baker - Let's talk about what it is, why it is a problem, and how Shopify handles it at scale across several GraphQL APIs.
2 - Contextualizing GraphQL APIs: Alex Ackerman - How and why we decided to use directives. I’ll share what directives are, which directives are available out of the box, and how to create custom directives.
3 - Faster GraphQL queries for mobile clients: Theo Ben Hassen - As your mobile app grows, so will your GraphQL queries. In this talk, I will go over diverse strategies to make your queries faster and more effective.
4 - Building tomorrow’s product today: Greg MacWilliam - How Shopify adopts future features in today’s code.
5 - Managing large APIs effectively: Rebecca Friedman - We have thousands of developers at Shopify. Let’s take a look at how we’re ensuring the quality and consistency of our GraphQL APIs with so many contributors.

In this workshop we will go through all the aspects and stages when integrating your project into Code Quality and Security Ecosystem. We will take a simple web-application as a starting point and create a CI pipeline triggering code quality monitoring for it. We will do a full development cycle starting from coding in the IDE and opening a Pull Request and I will show you how you can control the quality at those stages. At the end of the workshop you will be ready to enable such integration for your own projects.
