During June 2025, this developer enhanced the logto-io/docs repository by updating the Next.js App Router integration guide to clarify the minimum length requirement for the cookieSecret environment variable. Using Markdown and a focus on documentation best practices, the update addressed potential build and runtime errors related to cookie encryption, aligning the guide with current security standards. By improving the clarity of configuration instructions, the work reduced the likelihood of misconfiguration and support requests. Although no bugs were fixed during this period, the documentation improvements contributed to better developer experience and long-term maintainability for users integrating with Next.js.
