Deploy and Run the Program

Next, we are going to ssh to the device and run our code...

ssh pi@raspberrypi.local

Once on the device, cd tweetmonkey to get into the project directory.

Then install npm packages using...

npm install

That's going to take a while, because it has to do the builds for the johnny-five and raspi-io.

Then configure your Twitter API environment variables using...

export TWITTER_CONSUMER_KEY="(value)"
export TWITTER_CONSUMER_SECRET="(value)"
export TWITTER_ACCESS_TOKEN_KEY="(value)"
export TWITTER_ACCESS_TOKEN_SECRET="(value)"

I recommend you sudo nano ~/.profile and add these environment variables to the end so they'll still be there the next time you login.

And finally, you can run your code with...

sudo -E node .

You have to use sudo because you're accessing the GPIO pins and that's just a requirement. The -E variable tells sudo to keep the environment variables from the current user. In case you haven't seen node ., that's just the command to execute the node runtime starting with the current directory.
