I'm using websql in angular 4 project , but Typescript can't find some of the types: 

 this.db = openDatabase('tes', '1.0', 'test', 2 * 1024 * 1024);

But some how is accepting the transaction :

this.db.transaction(function (tx) {
  tx.executeSql(query);
  tx.executeSql(qr);
})

I'm always getting :

error TS2304: Cannot find name 'openDatabase'
