“Web-first”

• using JavaScript technologies and libraries allows for isomorphic code that can run on the server as well as in the user’s browser

• chart engine is based on d3.js / vega.js and all charts are rendered exactly the same way for online reports (in the brower) as for PDF reports (on the server)

• Cinnamon’s reporting logic (segmentations, translations) is written in TypeScript and therefore can be run both on the server and in the browser as well

Scalability

• using node.js as our server platform allows for scalability

• our reporting services are designed to run as microservices

  • separating the services for general reporting productions, word/pdf rendering and portal services

  • use of streaming software to decouple services

• use of caching for all data sources to improve performance

• PM2 or kubernetes clusters

• redis streams

• redis caching

Open source

• all features are based on open-source libraries (where enterprise-grade is available)

• only mandatory comercial software is Aspose.Words for PDF-reporting

• node.js, express.js

• redis

Independence of data source technologies

• main access to data sources is via REST API’s

• preference for document databases as data/document store

• mongoDB
