so I'd recommend either using JS as-is and learning how to use its abstraction capabilities to write reliable and maintainable code, or if you really want static typing, to use a language that was actually designed for it from the start Thx for the long answer. But the question was more on the techincal side using TS in Node.js instead of JS. Does Node have any issues working with TS instead JS? In frontend we are using TS, so it would be nice, to have same language in backend. All docs for Node are using JS for example, but why? Does Node not work well with TS? Or is it just historical because Node in the beginning was only supporting JS? If the question is not so clear, sorry for that, i am not a native english speaker, i try my best to be clear here :-) | 13:13:53 |
 joepie91 🏳️🌈 | moritz: right, so TS is just a language that compiles to JS, it's not a language that you run directly in anything | 13:15:02 |
| joepie91 🏳️🌈 | that's also why its type system is so limited, it needs to work around the design that JS has because it ultimately needs to be turned into JS to run it | 13:15:24 |
| joepie91 🏳️🌈 | ie. there's no such thing as a "typescript runtime" | 13:15:37 |
| joepie91 🏳️🌈 | that means that: 1) you can use TS anywhere you use JS, as long as you do the build step in some way, and 2) nothing 'runs' TS, everything runs JS, and so all documentation will be using JS because that's the language that's actually being used, you can think of TS as an unofficial third-party layer on top of it | 13:16:31 |
| joepie91 🏳️🌈 | does that make sense? | 13:17:18 |

does that make sense? Yes, this i already know. | 13:17:34 |
| moritz | I know what TS is and how it works. But i am not sure about TS with Node. | 13:18:15 |
| joepie91 🏳️🌈 | what I am trying to say is that "how TS works" means that there cannot be issues with TS in Node, from a technical perspective | 13:18:37 |
| joepie91 🏳️🌈 | but that because of that, there's also no reason for the Node docs to mention TS at all, it's just a third-party tool | 13:19:02 |

| moritz | So i only need to do this extra step: compile TS to JS to get Node running. | 13:25:54 |
| moritz | I found this https://www.digitalocean.com/community/tutorials/setting-up-a-node-project-with-typescript I guess this is exactly doing, what i want. | 13:26:13 |
| moritz | So it is time for me to learn TS now :-D | 13:27:57 |

So i only need to do this extra step: compile TS to JS to get Node running. basically. you can either set up tsc to manually compile or auto-compile on file changes, or use a wrapper like ts-node that makes it look like you are running TS in Node by compiling it behind the scenes whenever you run your code | 13:46:14 |
| joepie91 🏳️🌈 | moritz: at a glance that tutorial looks okay | 13:46:46 |
| joepie91 🏳️🌈 | it doesn't tell you to use webpack, which is good | 13:46:55 |
| joepie91 🏳️🌈 | (a lot of the bad tutorial writers don't understand the difference between a compiler/transpiler and a bundler, and think that you need webpack to run TS in Node) | 13:47:14 |
