Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

TypeScript Without Transpilation
I thought this was going to be a project like ts-node [1]

Deploy a static site to AWS S3 and CloudFront using AWS CDK
The command specified in the app option uses ts-node by default, which is an execution engine for Node.js that allows you to run TypeScript code directly. The --prefer-ts-exts flag prevents ts-node from prioritizing precompiled .js files and will always import the TypeScript source code instead, if it is available. This is useful if you are also using tsc (the TypeScript compiler) alongside the app option. The bin/cdk.ts file is the entry point for our CDK app, which defines the main function that will be executed when the app is run.
- Use tsx instead of nodemon

Couple super basic Typescript questions from a newbie: how to compile and how to start learning
If you want to write apps that run on Node.js I would suggest using Google’s TypeScript style guide. You can start using it by simply running npx gts init. I’d suggest that you start with this and run your apps using ts-node/ts-node-dev because it does not require an extra build step.

An Introduction to Deno: Is It Better Than Node.js?
It does support ESM, with a --loader[1], but even with its SWC option it’s still significantly slower than the esbuild loader I’m working on. Unfortunately, esbuild isn’t totally compatible with tsc, so it’s not a drop-in replacement without plugins.

How to Set Up a Node.js Project with TypeScript
The process of compiling TypeScript source files into JavaScript code before executing them with Node.js can get a little tedious after a while, especially during development. You can eliminate the intermediate steps before running the program through the ts-node CLI to execute .ts files directly. Go ahead and install the ts-node package using the command below:

How to use execa@6 with NestJs?
I tried suggested solution by https://github.com/TypeStrong/ts-node/issues/1007 but this causes problem with NestJS decorators:

- Good bye "typescript-is" (ancestor of "typia", 20,000x faster validator)

Typing for JSON Payloads
I'll throw https://github.com/woutervh-/typescript-is in the mix as well.

Handling json input in an express app
I'm a fan of typescript-is. Provides both compile time and run time validations

What can I *use* Rust for?
For what it's worth, thanks to TypeScript transformers (a feature baked into the compiler), one can create a transformer library that verifies an object is valid for any TypeScript type and conveys that information to the typechecker. And indeed, it's already been made. It allows to parse unknown into a given T. This is nice, because one can generate a JSON schema out of a TS type, for other languages/codebases to integrate safely.
-
Do you use code generators? If so, which ones?
But to make it worth the comment, I’ll point people to typescript-is which uses transformations at compile-time to generate run-time type checking code.
-
TypeScript runtime type-checking - designed for simple use, through to enforcing API payload schema
Then there's also typescript-is, which is pretty neat because it converts actual compile-time type definitions to runtime type checks, so it doesn't require changing the type definitions.
-
JSON Schema === Runtime Type System for TypeScript
typescript-is. This uses a compile-time transformer to generate code for type-checking. You'll need to use ttypescript instead of typescript to compile your code (I recommend setting this up with ts-patch). It won't work if your build pipeline is actually using something like esbuild or Babel to transpile TS->JS.

How an Anti-TypeScript “JavaScript developer” like me became a TypeScript fan
If you're not using a bunch of generics, check out typescript-is [1]. It takes little work to get it setup, but it generates run time type checks for you. I understand why typescript decided to not add this functionality to the core of the language, but it's starting to feel like the largest missing piece of typescript is a built-in way to generate run-time type-checks for user-defined types from just the type definition.
The happy medium we've found with that module is using the runtime type-check on anything "unsafe" to bless the result using typescript-is's equals functionality, but still allowing programmers to use casting with a comment justifying its necessity. For us our list of unsafe is results pulled from the db, anything parsed from JSON, and incoming request bodies (which can be a special case of parsing from JSON, but not always).
