tsyringe VS Nest

Alguns frameworks trabalham desta forma por padrão, como é o caso do Angular, quando este não é o padrão do framework que utilizamos podemos usar alguma biblioteca, como a Inversify ou tsyringe da Microsoft.

We are writing a backend application that handles a data stream and provides REST and GraphQL endpoints to query and manage these data. We are using TypeScript with Express.js and TSyringe for our DI container.

This is exciting but also make be a bit nervous as my projects make extensive use of https://github.com/microsoft/tsyringe and the decorator changes are not going to play nice.

If you don’t want to tie yourself to a full web framework like Nest, there are a few DI-only frameworks that work with decorators, like TypeDI, TSyringe, or Typed Inject.

In next post I will show you how to using with other DI package like awilix , tsyringe, etc...

It is written in Typescript, it is modeled similarly to the Microsoft tsyringe (which I was using previously).

For existing projects, or if you don't want the weight of an opinionated framework like Nest, libraries like TypeDI and TSyringe can help.

I personally still always opt for that pattern to start with and refactoring to some sort of Reader monad as the application grows. Others may prefer instead to go the route of decorators and reflection with tsyringe.

When using the NestJS framework, sometimes you may need to change some default timeout. You can define them just like you'd do in a plain Node.js HTTP server like so:

Back: a graphQL server built with Nestjs

NestJS - opinionated more scalable, but harder to learn docs

Pragmatically, we can apply this to a Nest application by creating an Interface for our services, separating the Presenter layer (Controller) from the Use Case (Services):

It’s a text document that contains all the commands a user could call to assemble an image. Let’s check an example of a Dockerfile for a nodejs app in this case it will be a NestJS app and then explain each part.

describe('Create bookmarks', () => { const dto: CreateBookmarkDto = { title: 'NestJS', link: 'https://nestjs.com/', }; it('should create bookmark', () => { return pactum .spec() .post('/bookmarks') .withHeaders({ Authorization: 'Bearer $S{userAt}', }) .withBody(dto) .expectStatus(201) .stores('bookmarkId', 'id')//store the bookmark id in the variable bookmarkId .expectBodyContains(dto.title) .expectBodyContains(dto.link) }); });

In my usual NodeJS tech stack, which includes GraphQL, NestJS, SQL (predominantly PostgreSQL with MikroORM), I encountered these limitations. To overcome them, I've developed a new stack utilizing Rust, which still offers some ease of development:

The purpose of this article is to provide a step-by-step guide for implementing authentication system in a NestJS project using the Passport middleware module.

That's exactly where I am. My manager gave me these links, that cover a lot of those words the backend uses, so I can identify what they mean and how to use them. 1. For inspiration and concepts: https://github.com/Sairyss/domain-driven-hexagon 2. Suggested to read the documentation for nest.js. They apply such concepts I don't understand: https://nestjs.com/
