Running our solution
It's time to see our code in action. Ensure that you have nsqlookupd, nsqd, and mongod running in separate terminal windows with the following:
nsqlookupd nsqd --lookupd-tcp-address=127.0.0.1:4160 mongod --dbpath ./db
If you haven't already done so, make sure the twittervotes program is running too. Then, in the counter folder, build and run our counting program:
go build -o counter ./counter
You should see a periodic output describing what work counter is doing, such as the following:
No new votes, skipping database update Updating database... map[win:2 happy:2 fail:1] Finished updating database... No new votes, skipping database update Updating database... map[win:3] Finished updating database...
Tip
The output will, of course, vary since we are actually responding to real, live activity on Twitter.
We can see that our program is receiving vote data from NSQ and reports to update the database with the results. We can confirm this by opening the MongoDB shell and querying...
