Thanks for the update. Can you explain what process.env is? and where can you set these values? Thanks.

Sure - process.env returns all the environment variables in your system. For the sake of this example, I kept it simple and secure by requiring the access token and secret be passed in as environment variables. In order to run this you would do:

TWITTER_CONSUMER_KEY="yourAppKey" TWITTER_CONSUMER_SECRET="yourAppSecret" node twitter-oauth.js

In the command line.

Thanks for sharing.

@celestialcitizen

I get the following error

[Error: 2712:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:openssl\ssl\s23_clnt.c:607:
]

Any ideas as to how to rectify the same ??

@kyledetella

Everything seems to work. However, I did have to change the endpoint for the credentials to : https://api.twitter.com/1.1/account/verify_credentials.json . (via: https://dev.twitter.com/docs/api/1.1/get/account/verify_credentials)

@gabmontes

Thanks for the example!

Is there any reason why URLs are twitter.com instead of api.twitter.com as documented on dev.twitter.com/?

@novalagung

thanks, this run great
