Salih enhanced the better-auth/better-auth repository by refining the Next.js integration guide, focusing on documentation clarity for onboarding developers. He updated the file naming example from 'client.ts' to 'auth-client.ts', aligning with TypeScript-oriented naming conventions and established integration patterns. This targeted change addressed confusion around file naming, reducing integration friction and supporting faster adoption for new users. Salih’s work demonstrated attention to documentation best practices and maintainability, though the scope was limited to a single feature update without bug fixes. The contribution improved developer experience by making integration steps clearer, ultimately lowering support overhead for the better-auth project.
