Metarhia: Node.js Macht Frei
The document discusses Metarhia, an experimental technological stack aimed at creating a unified software development environment that primarily uses JavaScript. It identifies issues with existing web technologies and proposes a new protocol, the JavaScript Transfer Protocol (JSTP), to facilitate real-time, interactive communication across applications. Additionally, it presents various components of Metarhia, including a global storage system and a console browser, which are designed to work seamlessly across multiple platforms.

- 3. #1 The Problem Webis terrible... Everyday you struggle for every step
- 4. #2 Alternatives Same taskfor desktop or mobile takes less time... ...but not easy distributed, needs installation, updates and so platform-dependent
- 5. #3 Metarhia Concept Whatif ... Remove everything except JavaScript
- 6. #4 Concept andPurpose We need applied software for following fields: • Business • Economics • Enterprise • Education • Medicine • Governance • Social Net • Communication • Trade • TV etc.
- 7. #5 Concept andPurpose We need applications to be at the same time: • Distributed (multiserver, multiclient) • Highload (billions of concurrent users) • Interactive (bi-directional in real time) • Secure (both anonymity and reliability) • Flexible (continuous self-updates)
- 8. #6 What wehave as of now? Now we have: • Locally installed Applications for Windows, Mac, Linux using Qt, WinForms, WPF, AWT, SWING... • Mobile Applications for iOS, Android, etc... • Web Applications GUI and b-logic should be implemented many times for different platforms
- 9. #7 Problems ofArchaic Web • HTTP is not designed for applications • HTML is not designed for rich UI or GUI • DOM is not designed for dynamic changes • AJAX is not designed for interactivity • REST is not designed for statefull apps Also Internet is full of trash: Search engines contains fakes, SEO and spam DNS are full of domaining and cybersquatting Data and content are mixed with GUI
- 10. #8 Archaic Web •HTTP is designed a long time ago • HTML is designed for hypertext • DOM is designed for static pages But we can’t change everything at once. We need both: • Compatibility • New solutions
- 11. #9 Temporary Solutions •HTTP: gzip, sprites, keep-alive, CDN, use HTTPS, HTTP/2 • DOM: use Angular, React.js, etc. (to speedup rendering and application development) • WebSockets: emulates TCP sockets over HTTP (overhead)
- 12. #10 All problemstogether • Platforms for applied software are fragmented • Web technologies are archaic and obsoleted • Protocols have great overhead and few features • Frameworks and tools are not stable and unified and changing all the time • We have great security risks
- 13. #11 Conclusion • Applicationsbecome obsolete quickly • We have a problems in application integration • No unification, less code reuse, fragmentation and extra work
- 14. #12 What weneed? We need following for applied software: • Server-side runtime • Client-side runtime with Renderer • Interprocess communication with: • RPC, MQ, streaming and introspection • S/C, S/S, C/C (P2P) interactions • DBMS designed to be globally distributed • New naming and identification conventions
- 15. #13 Introduction toMetarhia Metarhia is a new Technological Stack • Experimental (just to demonstrate fresh vision) • Alternative (should not support compatibility) • Open Source (free and no vendor dependent)
- 16. #14 Metarhia components •JSTP JavaScript Transfer Protocol • Impress Application Server • Global Storage distributed DBMS • Console new generation browser
- 17. #15 JavaScript TransferProtocol JSTP is a family of data formats and the libraries and implementations for different languages and platforms based on several simple assumptions: • Simple and well-known format • Interactive communications • Reactive data processing • Real-time bidirectional interactions • Focused on optimization and highload
- 18. #16 JSTP Ideas 1.We can take data serialization format, already available for multiple platforms This format is not even JSON it is JavaScript itself 2. Use metadata everywhere: for schema model, for data representation minimization, for flexibility
- 19. #17 Metarhia andJSTP Ideas Minimization of data transformations Single data format for: • Persistent storage in database, • Representation in server memory • Serialization and protocol • Representation in client memory • Intersystem data exchange
