ts-node VS DefinitelyTyped

I thought this was going to be a project like ts-node [1]

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.

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.

ts-node (“TypeScript execution and REPL for Node.js”)

Here is a relevant discussion and dev comment: https://github.com/TypeStrong/ts-node/issues/155

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.

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:

I tried suggested solution by https://github.com/TypeStrong/ts-node/issues/1007 but this causes problem with NestJS decorators:

Prior to React 18, it used to include an implicit children prop, making it suitable for components expected to have children. For a long time, though, the implicit children prop type has been removed according to React 18's type changes.

Additionally, because TypeScript has a well established and widely used install-base, there are already many different definition files in the wild for supporting non-TypeScript supporting projects. One of the more extensive collections of these typings lives at the DefinitelyTyped repository, which publishes the package's community typings under the package names @types/your-package-name (where your-package-name is the name of the project you're looking for typings of) that you can look for on your package manager.

Their type definition for HAR request isn't exported https://github.com/DefinitelyTyped/DefinitelyTyped/blob/mast...

type NumberOrString = number | string; type Status = "idle" | "loading" | "success" | "failure" // React useState, can receive a value or a function as parameter to serve as initial value. // https://github.com/DefinitelyTyped/DefinitelyTyped/blob/a03856975a17eba524739676affbf70ac4078176/types/react/v17/index.d.ts#L920 function useState(initialState: S | (() => S)): [S, Dispatch>];

The TypeScript pull request was merged, so Sebastian (who helps maintain the React type definitions) exercised new powers in this pull request to the DefinitelyTyped repository for the React type definitions. At the time of writing, this pull request is still open, but once merged and shipped the React community we will feel its benefits.

there is an open issue: https://github.com/DefinitelyTyped/DefinitelyTyped/issues/61616

Relatively infrequently. Normally, if an npm package is popular and doesn’t have its own types, there will be a community provided types declaration file available from https://github.com/DefinitelyTyped/DefinitelyTyped
