What Are *.d.ts files? How to Use *.d.ts Files in TypeScript?

[monkeymagic]

Yeah really helpful. I was confused about whether the d.ts files are just for auto-generated type definitions and/or used to define types. Your suggestion to leave .d.ts files for auto-generation and .ts file for locally defined types has cleared the mist for me.

For a long time I was wondering what these *.d.ts files are and what these are used for.
This video cleared all the doubts about it.
Thanks from India for sharing.

Thank you for this video ! I finally understand why I was struggling so much to install "Vue 2" libraries like vue-zoomer or vue-picture-swipe. They didn't support typescript apparently so they don't include the /type folder with the index.d.ts definitions either.
If anyone else faced this issue I resolved it by adding a 'declare module 'vue-zoomer';' line to my 'shims-vue.d.ts' file and then I can follow instructions from the Github or official website for the library in order to add the components. What this does is treats the component as an 'any' type which still works fine (you just don't get the benefits of strongly typed javascript while using typescript).

You are plain awesome! The best explanation to understand types in TypeScript.

This is really helpful! Well done and thank you :)
It seems like .d.ts files are a parallel to interfaces in Java, since you export function definitions but not implementations. It might be interesting to see a .d.ts file used that way

[kevinnacario]

Thank you so much, this was very informative!

[jeferson.luckas]

Thanks for the explanation, I used files like that but I didn't know why.

[valentinussofa]

Very helpfull Sir. I have problem like this in my express-handlebars. Many thanks from Indonesia.

[raymondmichael]

Thanks this is quite helpful, as I'm learning

[grzegorzzych]

Hey Maksim, great channel.
As I know you don't need to export types from *.d.ts files. Types should be available w/o export/import.

[specterepiphane]

thanks for the video. it is well explained

[codecodecode]

Thank you for amazing tutorials!
Which extension do you use: "VSCode Neovim" or "Vim"? If first one, how did you manage to fix mouse selection? Thank you in advance!

[omarislearning]

Thanks for the video, and if you can make a video series covering tsconfig, project reference, and other topic regarding tsconfig as even the official docs aren't that easy to understand.

Thanks for these explanations!
How do I generate d.ts files for an npm package that doesn't not have one ?
