如何將現有的伊斯坦布爾json文件轉換爲html

Question

我想將istanbul覆蓋率報告文件從JSON格式的客戶端轉換爲html格式。目前我使用的是remap-istanbul，但實際上，特定的工具旨在重新映射原始用不同語言（如打字稿）編寫的代碼的覆蓋率數據。

所以我想是否有更便捷的方式做同樣的

使用istanbul report html現有的覆蓋數據從JSON轉換爲HTML：

istanbul report html 

默認情況下，在當前上述外觀目錄（及其子目錄），以任何以「coverage」開頭並以「.json」結尾的文件，並將HTML報告輸出到./coverage/目錄。

到特定文件轉換爲特定的目錄：

istanbul report --include path/to/my-coverage-file.json --dir my-coverage-dir html 

另一種方式爲只讀從一個特定的目錄覆蓋報告（如path/to所有JSON文件）如下，使用--root選項：

istanbul report --root path/to --include=*.json --dir my-coverage-dir html 

使用istanbul help report看到更多選項（如下與伊斯坦布爾0.4.5生成）：

Usage: istanbul report <options> [ <format> ... ] 

Options are: 

     --config <path-to-config> 
       the configuration file to use, defaults to .istanbul.yml 

     --root <input-directory> 
       The input root directory for finding coverage files 

     --dir <report-directory> 
       The output directory where files will be written. This defaults 
       to ./coverage/ 

     --include <glob> 
       The glob pattern to select one or more coverage files, defaults 
       to **/coverage*.json 

     --verbose, -v 
       verbose mode 


<format> is one of

     text text report that prints a coverage line for every file, typically

       lcov coverage report that can be consumed by the lcov tool 
     text-summary 
       text report that prints a coverage summary across all files, 
       typically to console 

Default format is lcov unless otherwise specified in the config file. In 
addition you can tweak the file names for various reports using the config 
file. Type `istanbul help config` to see what can be tweaked. 

--input的值是一個glob模式。有關全局模式的更多文檔，請參閱documentation at the glob package on NPM。
