class-transformer VS typedi

JSON serialization is 200x faster than class-transformer

Also OP can check out class-transformer + class-validator if he want to properly instantiate objects and validate them with precise and verbose output of potential format errors. OP can even go the god tier way by setting up a custom RxJS operator that does that for him easily.

Start by installing the class-transformer and class-validator packages for dto validation (see more in the docs), sharp for image optimization, and the S3 client packages.

And you can always transform the input in the DTO using class-transformer or use case insensitive when you search.

Anyone here using https://github.com/typestack/class-transformer and now seeing intermittent failures using either plainToClass or plainToInstance?

My two cents: class-transformer it will require to use decorators in your code, but it can handle more cases

In this tutorial, we're building a simple application which uses Cerbos inside of a GraphQL server. The server is written in typescript and uses type-graphql to create the schema and resolvers, and TypeDI to handle dependency injection.

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.

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

The TypeDI project aims for simplicity by leveraging decorators and decorator metadata. It supports dependency scoping with singletons and transient objects and allows for multiple DI containers to exist. You have two options for working with TypeDI:

There are a number of Javascript dependency injection container libraries out there. Some of my personal favourites are TypeDI and InversifyJS. Here is an example demonstrating basic usage of Typedi with JavaScript.

typedi TypeDI is a powerful dependency injection package that has many features. One of this features is having Singleton Services which is how we use it in our case.
