概述
代码格式化预提交工作流是一个初级难度的工作流。设置预提交钩子在每次提交前自动格式化代码，保持团队代码风格一致。该工作流的目标是：Enforce consistent code formatting automatically before any commit is created.
环境准备
执行本工作流需要以下环境：A project with a code formatter installed；Git repository with hooks directory；Team agreement on formatting rules。请确保在开始前准备好所有必需的工具和资源，以避免中途因环境问题中断。
执行步骤
本工作流包含3个步骤。步骤1：Install hook——Create a .git/hooks/pre-commit script that runs the formatter on staged files. 步骤2：Test the hook——Make a formatting violation, stage the file, and attempt to commit. 步骤3：Verify formatting——Check that staged files are formatted correctly after the hook runs.
验证与清理
预期结果：All commits automatically have formatted code, preventing style inconsistencies from entering the repository.。验证方法：Make a commit with unformatted code and confirm the hook reformats it or blocks the commit.。清理操作：Remove the pre-commit hook if needed with rm .git/hooks/pre-commit.。estimatedMinutes 为 15 分钟。
代码示例
#!/bin/sh
prettier --write $(git diff --cached --name-only --diff-filter=ACM | grep "\.js$")
