1. By files

   If you want to merge group of files use like this.

           new MergeJsonWebpackPlugin({
                                 "files": ['./jsons/file1.json',

Field Name	Description
files	Array of json files to be merged
output.fileName	Name of merged output file

1. By Patterns

   This plugin uses glob for searching file patterns,please refer glob for usage for sample pattern.
   You can specify a pattern to pull all the files that satify the particular pattern and output a single json file.

   new MergeJsonWebpackPlugin({
               "output":{
                 "groupBy":[
                               { "pattern":"{./jsons/module*/en.json,./jsons/file1.json}", 
                                  "fileName":"./dist/en.json" 
                               },
                               { "pattern":"{./jsons/module*/es.json,./jsons/file2.json}", 
                                   "fileName":"./dist/es.json" }
                           ]        
                       }
              })  
   

groupBy	Array of patterns and corresponding fileNames.
groupBy[].pattern	Pattern to search files for. eg: **/en.json will pull all en.json files under current working directory and sub directories
	Do not use curly brackets if there is only single pattern to consider	pattern:"./node_modules/**/en.json"
	Use curly brackets to group more than one pattern together	pattern:"{./node_modules/**/en.json,./src/assets/i18n/en.json}"
groupBy[].fileName	output file name for the corresponding pattern.
