tsx VS dnt

For other tools, you should check their documentation on custom conditions support. I've tried to run my project with tsx. As it supports all Node.js flags, I've just provided custom condition via -C flag:

Luckily, this is a very common thing and Tsx, a can help us with this. We simply have to import this module and we'll be able to execute Typescript code with Node.js:

Next, we need to set up a development script that will watch for changes in our TypeScript files and recompile them. Personally, I like to use tsx, as it provides a much faster development experience compared to the built-in TypeScript watcher or ts-node. First, install tsx:

At this point, you will have a setup which relies on tsx to understand TypeScript, and jsx-async-runtime to understand JSX/TSX templates.

I really enjoy frontend/node/typescript development. I roll my eyes whenever the HN-types complain about CSS or frontend development being a hellhole. Mostly the comments I see seem ignorant or impatient ("Why doesn't this thing work without be bothering to learn it?")

However, the intersection of typescript, nodejs, and ES modules is consistently the most frustrating experience I ever have. Trying to figure out which magic incantation of tsconfig/esbuild/tsc/node options will let me just write code and run it is a fools errand. You might figure something out, and then you try to use Jest and then you descend into madness again.

The biggest tip I can give people is to ditch ts-node and just use (the awkwardly named) tsx https://github.com/privatenumber/tsx, which pretty much just "mostly works" for running Typescript during dev for node.

The problem mostly seems to stem for all the stakeholders being pretty dogmatic to whatever their goals are, rather than the pragmatic option of just meeting people where they are. I really wish the Node, Typescript, Deno/Bun, and maybe some bundler people would come together and figure out how to make this easier for people.

If your TypeORM entity is written in TypeScript, you have to run ERDIA using ts-node or tsx as follows.

Want to import a package / file conveniently from esm.sh or unpkg or directly from a GitHub repo for a one-off script (for example). To do this I created a custom ESBuild plugin to handle HTTP imports - that worked for ,js files. To support running both ESM and CJS, I use tsx.

I prefer tsx honestly. Nodemon will detect that your using TypeScript and switch from node to ts-node but tsx is a no config necessary version of ts-node that also runs faster. Of course you can configure ts-node to use swc to be faster but then you're playing with config files to get things working.

I highly recommend you give this a shot over ts-node

We are going to use dnt - Deno to Node Transform tool to build the npm package.

As already mentioned dnt might help you if you are willing to have deno as your primary development environment. I work in a project like this and the deno tooling is great. I don't even need a package.json since dnt will generate it for me.

Build it in Deno and then use dnt to create an npm package. That way you support both JS runtimes: https://github.com/denoland/dnt

Specifically, make my codebase be for Deno, use Deno built-in formatter, linter and testing, and use dnt (Deno to Node Transform) to generate an npm package containing ESM code and to test generated code. For testing in the browser, deploy the test content linked to the generated ESM code to Github Pages and use playwright/test. For Cloudflare Workers, use wrangler to set up a worker locally for testing. A schematic diagram is shown below.

I ended up building the library with Deno and compiling to Node.js CJS and ESM using https://github.com/denoland/dnt

Yes, TS code is compiled to run in browsers. You can compile and bundle using `deno bundle` if your project is developed in Deno. Since I'm using Deno for library development, I use the `dnt`[1] tool to compile them into ESM modules later consumed by esbuild in my Node-based projects/toolchains.
