Read streaming data using web api and save to mongodb

i am using request package of npm.

and this code on server side

request.get(“url”).pipe(process.stdout);

it process the get api and prints data every 2 second on console.

but in .pipe() method if i write any function to do any thing rather then process.stdout it gives error.
