Side Project: Building Jaksim Friend

writingblogprojectreact-native

Summary

  • Published 2024-02-07 · slug jaksim-friend-react-native-retro · category "Projects, hackathons, and competitions / Side projects" · source article recorded in Korean and English.
  • A retrospective on "Jaksim Friend," a social goal-setting app built as a side project in 2022. As frontend lead in a five-person team, I participated in planning, design, development, and submission for app-store review, aiming for simultaneous iOS and Android releases.
  • The article explains choosing React Native and TypeScript for cross-platform development and type safety, Recoil to avoid Redux boilerplate, and Styled-Components.
  • For maintainability, I separated an Axios-based API layer into src/apis and extracted recurring logic such as authentication into custom hooks like useAuth.
  • Lessons included experiencing the full app-development cycle and the importance of clean code. Shortcomings were a failed team-building process that stopped deployment, and the absence of tests. The article explicitly states that the project did not reach release.
  • The source note records isPrivate: true in the blog frontmatter. Its repository inspection found a type declaration but no use of that field in listing or routing; the note therefore flagged actual publication status for confirmation. The URL follows the same /archive/ convention as other posts.
