Transcript

1. nest | progressive node.js framework | scalable +
2. @JecelynYeen From Kuala Lumpur, Malaysia • GDE - Web technologies, Angular • Software Architect @ Randstad Organizer:
3. • node is good, but… • nest is here to… • nest core concepts - live coding +
4. Story of building LEGO house
5. simple, intuitive, easy to start
6. structure, details, layout
8. - Design & Plan - Modular - Ecosystem
9. Software Development with
10. JavaScript runtime that built on top of Google Chrome’s V8 engine.
11. is simple… - Setup time: 1 minute - Code: 2 lines
12. const app = require('express')(); app.listen(3000);
13. const app = require('express')(); app.get('/', (req, res) => res.send('hello, simple house!’)); app.listen(3000);
14. Why ? Language Reusability Productivity Community
15. Simplicity Wait, what is the definition of simple?
16. is simple up to a certain point When build medium - large applications, the definition of simple change.
17. Application Issues (Medium to Large) Lack of common architecture Fragile execution Problematic growth Structure Robustness Scalability
18. “We build our computer (systems) the way we build our cities. Over time, without a plan, on top of ruins.” - Ellen Ullman
20. Why ? Application Architecture Dependency Injection Middleware Structure Platform Agnostic

23. What’s (the good stuffs) in the project? Typescript Jest Nest
24. Core concepts Controllers Providers Modules Middleware Exception filters Pipes Guards Interceptors https://docs.nestjs.com/first-steps Controllers Providers Modules Middleware
25. Let’s code!
26. Platform Agnostic GraphQL Microservices Web Sockets Building apps with several transport layers & contexts
27. is Low entry threshold Fully featured Open source Compatibility
28. “It’s never on how difficult is to write bad code, it’s on how easy is to write good code.”
