From Flaky to Flawless: Angular API Response Management with Zod
Zod is an open-source schema declaration and validation library that emphasizes TypeScript. It can refer to any data type, from simple to complex. Zod eliminates duplicative type declarations by inferring static TypeScript types and allows easy composition of complex data structures from simpler ones. It has no dependencies, is compatible with Node.js and modern browsers, and has a concise, chainable interface. Zod is lightweight (8kb when zipped), immutable, with methods returning new instances. It encourages parsing over validation and is not limited to TypeScript but works well with JavaScript as well.

You can’t run away from runtime errors using TypeScript
Zod is a TypeScript-first schema declaration and validation library. It helps create schemas for any data type and is very developer-friendly. Zod has the functional approach of "parse, don't validate." It supports coercion in all primitive types.

What even is a JSON number?
In JS, it's a good idea anyway to use some JSON parsing library instead of JSON.parse.
With Zod, you can use z.bigint() parser. If you take the "parse any JSON" snippet https://zod.dev/?id=json-type and change z.number() to z.bigint(), it should do what you are looking for.

We will validate our input using client-side zod. Zod handles TypeScript-first schema validation with static type inference. This means that it will not only validate your fields, it will also set types on validated fields.

Zod: Zero to Hero - Chapter 4
A word of warning: while discriminated unions are very powerful, there's an ongoing discussion on whether discriminated unions should be deprecated and replaced with a different API.

Zod: Zero to Hero - Chapter 1
I was first introduced to Zod by Adam Bobrow - a colleague of mine and a dear friend. Adam was sick and tired from JavaScript's brittleness, and about two years ago he started migrating our code base to TypeScript. But that wasn't enough for him. He kept complaining: "What good are my types, if some other service decides to send me bad data and breaks my code?". That's when he discovered Zod.

Unleashing the Power of TypeScript: Improving Standard Library Types
TypeScript's standard library contains over 1,000 instances of the any type. There are many opportunities to improve the developer experience when working with strictly typed code. One solution to avoid having to fix the standard library yourself is to use the ts-reset library. It is easy to use and only needs to be imported once in your project.

Why doesn't TypeScript properly type Object.keys?
You might like TS Reset: https://github.com/total-typescript/ts-reset, which fixes this particular problem. I don't personally find it to be a big issue though.
Regarding runtime type checking, if you were to write something that can handle the total space of possible TS types, you would end up with incredibly complex machinery. It would be hard to make it perform, both in terms of speed and bundle size, and it would be hard to predict. I think Zod or perhaps https://arktype.io/ which target a reasonable subset are the only way to go.

Books/resources to improve TypeScript knowledge
Dude is an actual TypeScript wizard, his ts-reset package is a must have when dealing with JSON. He was featured in the VS Code day streams to show off some introductory TypeScript concepts and my big takeaway from that stream was this VS Code extension. Just stick // ^? on the line after something and it shows the type of the line above. Amazing with Prisma.

Typescript really hits the middle ground between extremely rigid statically typed languages on one extreme and no types at all dynamic languages on another extreme. Best type system
Personally I quite like ts-reset to "fix" some of the std lib types - JSON.parse will now return unknown. It's then up to you to decide how you wish to parse that unknown (zod, runtypes, io-ts are all reasonable options here). Won't ever be done by TS itself, as generating runtime code is a non-goal for the project.
