JSDoc is this how you mark a @typedef as @global?

Question

Just making sure that this in a module in our Node server is the right way to be able to use an @typedef throughout the application instead of repeating it in every module/file it is needed. From the docs I can't determine if this is correct or not, and does anyone have an opinion on where to store global @typedefs so they are easy to find if they need to be changed when used throughout the application.

/**
 * Universally unique identifier.
 * @global
 * @typedef {string} UUID
 */

Answer 1

A bit of a late answer here, but I came across this issue from Google, so this is how I solved this issue for myself. Hopefully it helps future people!

I ran into a similar situation where I had a typedef in a module and wanted to use that type elsewhere in the application, without redefining the type.

I went with something like this:

myModule.js
/**
 * Universally unique identifier.
 * @typedef {string} UUID
 */

myOtherScript.js

/**
 * @function
 * @param {import('path/to/myModule.js').UUID} uuid
 */
function getByUUID(uuid) { ... }

This doesn't make the typedef strictly global, so you cannot do @param {UUID} uuid (which would be cleaner, however I've yet to find a way to achieve this) but this approach worked for my use-case, and definitely is better than rewriting the type everywhere it is used.
