1. JS Freakin’ Everywhere A Chatbot Powered by AWS+NodeJS
2. Me, a year ago. Ecstatic Art Driftwood Flea Market Buddhist Retreat 100% NO JS
3. Along came a startup founder... We made a bot! It helps people! Help us build it!
4. Who sat down beside me... And it has a punny name!!
5. And enticed Miss Pammy to code And we’re building it all in something called “NodeJS”!
6. And we’re off to the races! From 0 to Scalable in 5 weeks. AWS Lambda AWS DynamodB AWS Beanstalk
8. Why Lambda?
9. SysOpsJS AWS Lambda Log Processor Cloudwatch BigQuery AWS Lambda Cloudwatch SlackBot Cloudwatch Slack deploy.sh Upload Notify Checks
10. BUT WHAT ABOUT NLP?? 99% buttons
11. We still have NLP tho...
12. NLP in JavaScript..ish! Python Classifier Training JavaScript Online Classifier svm intercepts svm weights tfidf scores mood matches
13. That takes time! Fine, we need to take time! How are you feeling? I’m excited about tonight Oh, that’s great to hear! • • • NLP! 500ms Twiddle thumbs
14. Our “CMS” We need a way to collaboratively write content for Woebot! And we want to A/B content! And we want to write variants! And lesson queueing! And conditional content based on variables! Also, we need it tomorrow!
