复制文件插件

插件包	@rushstack/heft (内置)
插件名称	copy-files-plugin 由 CopyFilesPlugin.ts 实现
插件配置文件	(无)
heft.json 选项	copy-files-options.schema.json

此插件使用各种通配符复制指定的文件或文件夹。

何时使用它

典型使用场景

• 将资产文件（如图像或字体）复制到“dist”文件夹中
• 在编译之前将 .d.ts 文件复制到 temp/typings 文件夹中
• 复制 node_modules 依赖项以进行重新打包

一些注意事项

• 不建议使用 copy-files-plugin 将资产复制到 TypeScript 发射文件夹中；请改用 staticAssetsToCopy，因为它与 additionalModuleKindsToEmit 和监视模式更好地协同工作。
• 避免使用此任务读取/写入项目文件夹之外的文件。这样做将违反 Rush 的 项目隔离原则。
• 在可能的情况下，避免使用 ** 等低效的通配符，这些通配符会递归遍历目录树。这些磁盘密集型操作会减慢构建速度。
• 过于广泛的通配符有时会包含 Git 未跟踪的杂散文件夹。

package.json 依赖项

无 - 此功能内置于 @rushstack/heft 中。

     * If true, filesystem hard links will be created instead of copying the file.  Depending on the
     * operating system, this may be faster.  The default value is false.

     * NOTE: This may cause unexpected behavior if a tool modifies the link. The contained directory
     * structure will be re-created and all files will be individually hardlinked.  This means that
     * folders will be new filesystem entities and will have separate folder metadata, while the
     * contained files will maintain normal hardlink behavior.  This is done since folders do not
     * have a cross-platform equivalent of a hardlink, and since file symlinks provide fundamentally
     * different functionality in comparison to hardlinks.
