Beyond cultivating the right mindset, scaling success requires making strategic decisions that lay the foundation for sustainable growth.

Technology Choices

Selecting the right technologies and frameworks can significantly impact scalability. Factors like performance, maintainability, and developer experience should be carefully considered. Notion’s migration to Next.js exemplifies the importance of choosing a technology stack that aligns with long-term scalability goals.

By adopting Next.js, Notion was able to leverage its performance optimizations, such as server-side rendering and efficient code splitting, to deliver fast and responsive pages. Additionally, the developer-friendly ecosystem of Next.js and its strong community support enabled Notion’s team to focus on building features and optimizing the user experience rather than grappling with low-level infrastructure concerns. This strategic technology choice laid the foundation for Notion’s scalable and maintainable architecture.

Ship Only The Code A User Needs, When They Need It

This best practice is so important when we want to ensure that pages load fast without over-eagerly delivering JavaScript a user may not need at that time. For example, Instagram made a concerted effort to improve the web performance of instagram.com, resulting in a nearly 50% cumulative improvement in feed page load time. A key area of focus has been shipping less JavaScript code to users, particularly on the critical rendering path.

The Instagram team found that the uncompressed size of JavaScript is more important for performance than the compressed size, as larger uncompressed bundles take more time to parse and execute on the client, especially on mobile devices. Two optimizations they implemented to reduce JS parse/execute time were inline requires (only executing code when it’s first used vs. eagerly on initial load) and serving ES2017+ code to modern browsers to avoid transpilation overhead. Inline requires improved Time-to-Interactive metrics by 12%, and the ES2017+ bundle was 5.7% smaller and 3% faster than the transpiled version.

While good progress has been made, the Instagram team acknowledges there are still many opportunities for further optimization. Potential areas to explore could include the following:

• Improved code-splitting, moving more logic off the critical path,
• Optimizing scrolling performance,
• Adapting to varying network conditions,
• Modularizing their Redux state management.

Continued efforts will be needed to keep instagram.com performing well as new features are added and the product grows in complexity.
