Just an FYI, both options for the mongoose connect function are deprecated as of version 4.0.0.

[Riswanch]

code works fine without any error bt when I check my database there is no new db created??why this happening ??I tried many methods and kind of fed up...

[Travel-rikf]

fix it, i am getting this error
(node:31652) [MONGODB DRIVER] Warning: useNewUrlParser is a deprecated option: useNewUrlParser has no effect since Node.js Driver version 4.0.0 and will be removed in the next major version
(Use `node --trace-warnings ...` to show where the warning was created)
