+## Source Maps
+
+By default, gitea generates reduced source maps for frontend files to conserve space. This can be controlled with the `ENABLE_SOURCEMAP` environment variable:
+
+- `ENABLE_SOURCEMAP=true` generates all source maps, the default for development builds
+- `ENABLE_SOURCEMAP=reduced` generates limited source maps, the default for production builds
+- `ENABLE_SOURCEMAP=false` generates no source maps

+
+默认情况下，gitea 会为前端文件生成精简的源映射以节省空间。 这可以通过“ENABLE_SOURCEMAP”环境变量进行控制：

+- `ENABLE_SOURCEMAP=true` 生成所有源映射，这是开发版本的默认设置
