Goal

Description

Example

“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
