How it is built

• Automated infrastructure configuration (AWS storage, content distribution network, DNS)
• Continuous integration pipeline via CircleCI: validates, builds and uploads content to AWS, insures clean code, review process, deploys every branch
• No secrets in the code, the code is in open-source
• No runtime back-end, everything is done at bulid-time, then uploaded on AWS S3
• Standard react app
• Uses React Simple Chatbot to define the chatbot flow and collect answers (completely in-browser, no server-side, no Rasa)
• Uses a rules engine to classify collected answers into one of several content classes
• Every piece of content belongs to a class. All content for a given set of classes is collected and served.
• GitHub is being used as a content management system, so the review is done via Pull Requests.
• Content is written in text files using Markdown format
• Content files are rendered via React Markdown
