* [Discuss architecture before implementation](#discuss-architecture-before-implementation)
* [Be consistent](#be-consistent)
* [Improve code iteratively](#improve-code-iteratively)
# Principles[](#principles "Permalink")
這些原則將確保您的前端貢獻從正確的方向開始.
## Discuss architecture before implementation[](#discuss-architecture-before-implementation "Permalink")
在編寫代碼之前，請先討論您的體系結構設計問題. 這有助于減少審閱時間，也為編寫和思考系統設計提供了良好的實踐.
## Be consistent[](#be-consistent "Permalink")
有多種編寫代碼以實現相同結果的方法. 我們應該在代碼庫中編寫代碼的方式盡可能保持一致. 這將使我們更輕松地在整個 GitLab 中維護代碼.
## Improve code [iteratively](https://about.gitlab.com/handbook/values/#iteration)[](#improve-code-iteratively "Permalink")
每當您看到不符合我們當前樣式指南的現有代碼時，請主動進行更新. 您不需要修復所有問題，但是每個合并請求都應迭代地改進我們的代碼庫，并在可能的情況下減少技術負擔.
