Why Angular?
- Opinionated
- Prescriptive
- Guided
- Supportive
In General
- TypeScript by default
- CLI
- Standard way of doing almost everything
Tech-Specific
Nest carries over the general and technical thing we like about Angular
Nest knows about the things we might need and is prescriptive about how to acheive them, while still be flexible.
Common Server Needs
- Delay app start - Async providers
- Middleware - NestMiddleware
- Communicating with databases
- ORMs
DEMO
How do I adopt Nest gradually?
Existing Node App
- HttpAdapter (for express or Fastify)
- Extract business logic and put Nest on top
Existing Something Else
- Reverse Proxy and slow migration

Angular Beyond the Front End
By Ryan Chenkie
Angular Beyond the Front End
When we build full-stack applications, we often need to use different languages and paradigms between the front end and backend. This comes with a cost. Context switching between the two can create friction and slow development. Even if we are only focused on development for one of these two areas, there are certain cross-team benefits that we're missing out on by using different technologies on the front end and backend. While we can't really use Angular on the backend, we can get pretty close. NestJS is a development platform for Node which is heavily inspired by Angular. Many of the concepts we know from Angular are directly mapped to a backend Node environment using NestJS. In this talk, we'll explore why it's beneficial to use Angular and NestJS together, regardless of whether you're a full-stack developer or you are part of a larger team.
