Elasticsearch jdbc-importer in Nodejs and postgresql

I want to use Elasticsearch within my project. I am using Nodejs and postgresql.

I want to connect postgresql with elasticsearch for this i am using jdbc-importer. I followed the steps written in their docs to connect with postgresql and i succeded in this but through command line.

I want to use jdbc-importer within my project through nodejs

commondline code to run jdbc importer:

bin=/Users/mac/Documents/elasticsearch-jdbc-2.3.4.1/bin
lib=/Users/mac/Documents/elasticsearch-jdbc-2.3.4.1/lib
echo '{
     "type" : "jdbc",
     "jdbc" : {
         "url" : 
        "jdbc:postgresql://localhost:5432/development",
        "sql" : "select * from \"Products\"",
         "index" : "product",
         "type" : "product",
    "elasticsearch" : {
    "cluster" : "elasticsearch",
    "host" : "localhost",
    "port" : 9300
}
     }
 }' | java \
        -cp "${lib}/*" \
        org.xbib.tools.Runner \
        org.xbib.tools.JDBCImporter

above command have created index product in elasticsearch and it also have data from Products table of postgresql.

Now, I want to use that jdbc importer through nodejs and If anyone elso knows other efficient way to manage my postgresql data in elasticsearch they are also welcome to give answere.
