I have used "mongodb" npm package for at time of mongodb integration. and for connecting with mongodb we have to create a url structure i.e "mongodb:userName:password@host:accessData/database".and at a time we are connected with one of the database that we provided on url.So it is possible to get all collections, field and documents of that database.But I am not find any way to get databases list because we connected with only one database.So I am skipped that event and go ahead with wordpress./////////////////////////////////////////////////////On wordpress I have completed authetication part. For authentication user have to provide SiteUrl, Username, Password.And currently working on events list of wordpress.I have completed several events for wordpress included "New Post Status","New Post Format","New Comment Status","New Category".I am using Xmlrpc method for getting data from wordpress.
