[Nestia] Boost up your NestJS server much faster and easier (maximum 20,000x faster)
JSON serialization is 200x faster than class-transformer

How can I declare, integrate a JSON (or similar type that is supposed to be data sent from a server) file into my Angular app, and use it;s data to display the array of Devices within it?
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.

NestJS GraphQL image upload into a S3 bucket
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.

NextJS + Prisma how to handle case sensitivity for usernames/emails?
And you can always transform the input in the DTO using class-transformer or use case insensitive when you search.

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

Fixing a Promise return object to be typed in Typescript

- 10x faster JSON.stringify() function and run-time type checkers
- Why doesn’t TypeScript natively do any type checking

Is there a simpler way to cast a complex object into a simpler object?
My two cents: class-transformer it will require to use decorators in your code, but it can handle more cases

When should I use runtime checks (and which runtime checker should I use)?
In terms of which runtime checker I should use. The first tutorial I saw suggested 'Zod', doing a bit more searchign yielded other options such as 'runtypes'.

An almost religious case for Rust
Runtypes would probably be a better example.

'The best thing we can do today to JavaScript is to retire it’ Douglas Crockford
this has been solved by several packages, runtypes https://github.com/pelotom/runtypes being my favorite

How to force a type when importing a JSON file?
I personally like https://github.com/pelotom/runtypes because it bundles your Schema Info and the corresponding Typescript types
- Why doesn’t TypeScript natively do any type checking

Create d.ts for API response
When I have to deal with data from API calls, I usually use a runtime typing library like Runtypes or Zod to check the responses at the boundary. These libraries can automatically give you TS types (using their static or infer utilities) to use throughout the rest of the project.
-
Typing for JSON Payloads
Also runtypes and (as mentioned below) zod.

How to check that an 'unknown' object has a specific key and that the key is a specific type?
Seconding the recommendation to use a library for this. runtypes and io-ts are two other alternatives.

Check types at the top level or in each function?
I wouldn't reinvent the wheel: https://github.com/pelotom/runtypes

Minimal and fast runtime API payload sanitiser and error message handling
What does your library provide that others don't? For example: https://github.com/colinhacks/zodhttps://github.com/hapijs/joihttps://github.com/jquense/yuphttps://github.com/gcanti/io-tshttps://github.com/pelotom/runtypeshttps://github.com/sindresorhus/ow
