Don't Rewrite Your App, Unless You Have To - Snap Engineering

Summary

The article discusses the Snapchat Engineering team's experience in rewriting their Android app to enhance performance and reduce bugs. It outlines the challenges faced due to the app's complexity and the decision-making process that led to the rewrite. The team focused on creating a modular architecture that allowed for faster loading times and better resource management. Key strategies included setting ground rules for development, maintaining a narrow scope to avoid scope creep, and adopting a Minimum Viable Product (MVP) mentality to ensure quality throughout the development process.

Key Learnings

• 1Rewriting an app can be a more efficient solution than incremental refactoring when faced with significant performance issues.
• 2Establishing clear ground rules and focusing on performance can help teams avoid common pitfalls during a rewrite.
• 3Adopting an MVP strategy allows teams to identify and address performance regressions early in the development process.
• 4Maintaining a modular architecture facilitates ongoing improvements and refactoring without the need for complete rewrites.
• 5Effective project management and communication are crucial to keep teams aligned and focused during lengthy development cycles.
