Standalone CLI in t3 project

Hi! So I wrote a question a while ago about making a little script for interacting with my db through prisma (https://discordapp.com/channels/966627436387266600/1024739607553786011) I was recommended ts-node to run the file, but that doesn't work at all. I think it has something to do with es6 imports/exports but it's really cryptic and I can't find much information about it. The error message looks like this:

PS E:\Github\frazzot-portfolio> npx ts-node .\src\utils\dbUtils.ts
(node:14184) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)

And the file is simply

console.log("Hello");

export {};

console.log("Hello");

export {};

Has anyone else ran in to problems like this? Any help, pointers or other recommendations for how I could run a .ts file in my t3 project without running the whole web app would be greatly appreciated

Dude thank you so much. That library just worked right of the bat

needmorewood•3y ago

no worries

Vincent UdénOP•3y ago

No config, no error, just worked exactly as expected

needmorewood•3y ago

egoist and antfu are god developers so if you see options from them they get it
