How can I ensure that JSDoc links to symbols in other files are rendered correctly in Visual Studio Code? I’ve noticed that this only happens when the symbol is explicitly imported in the current file. Is there a way to configure or modify this behavior to support links to symbols that are not directly imported?

I’ve been diving into JSDoc lately and have run into a frustrating issue that I hope someone here can help me with. So, I’ve got a pretty large project with multiple files, and I want to make sure that my documentation stays clear and connected. The problem I’m facing is that when I create links to symbols in other files, they only seem to work if I explicitly import those symbols in the current file.

For instance, let’s say I have a function in `utils.js` that I want to reference in `app.js`. If I just use the JSDoc tag to link to that function without an import, the link doesn’t render correctly in Visual Studio Code. This makes my documentation feel a bit disjointed, and it’s definitely not the experience I want for anyone who might be reading the documentation.

I’ve tried a couple of different approaches like different JSDoc tags (`@link`, `@see`, etc.), but I’m still hitting that wall. It feels a bit unintuitive since I would expect JSDoc to recognize the symbols across my project regardless of whether they’re explicitly imported or not. Does anyone know if there’s a way to modify this behavior? Is there a setting in VS Code or maybe something in my JSDoc configuration that I’m missing?

I also wonder if this is a common issue or just something I’m running into because of the way I’ve structured my project. Could it be related to the way TypeScript handles modules and imports? If anyone has stumbled upon a solution or workaround, I’d really appreciate your insights. I’m sure this is something that could help a lot of developers who are trying to maintain clear and connected documentation across their codebase.

Thanks in advance for any tips or tricks you can share!

    1. It sounds like you’re dealing with a pretty common issue when working with JSDoc in a modular setup! I’ve had some headaches with linking too, especially in larger projects.

      From what you’ve described, it seems like JSDoc is treating files as separate modules when you don’t explicitly import the symbols. This means it might not recognize references that don’t come from imports.

      One workaround I found is to make sure that you’re using the correct syntax for the links, like:

      @link utils.functionName

      But if that still doesn’t work without an import, you might want to look into your TypeScript configuration or JSDoc settings. In some setups, you can tweak the tsconfig.json to help with module resolution.

      Also, check if your JSDoc config has any options related to module resolution or linking symbols across files. It could be worth diving into the documentation for JSDoc or even raising an issue on their GitHub if you think it’s a bug!

      And yeah, I think a lot of people hit this wall when they first start using JSDoc with TypeScript! Hopefully, there’s some solution that will make your documentation feel a bit more connected.

      Good luck, and let us know if you find a fix!

    2. When working with JSDoc in a large project that spans multiple files, it’s not uncommon to encounter issues linking to symbols across different modules without explicit imports. In JavaScript, especially when utilizing ES6 modules, JSDoc typically relies on the imports to correctly resolve references between files. This limitation can indeed create a sense of fragmentation in your documentation, as links to symbols may not render correctly in environments like Visual Studio Code unless you’ve explicitly imported those symbols in your current context. To mitigate this problem, you might explore strategies that involve ensuring consistent module exports and imports, which can help JSDoc better understand your project structure.

      To address the specific challenges you’re facing, ensure that your JSDoc configuration is set up correctly, as certain configurations can impact how symbols are linked across files. Additionally, you might want to look into using the `@module` tag for clearer module definitions and to explicate the relationships between different files. It’s also beneficial to consider the implications of using TypeScript, as it enforces an explicit import pattern which could be affecting JSDoc’s ability to resolve symbols. If your goal is to keep the documentation connected without modifying imports frequently, consider designing your project structure to minimize unnecessary complexity, possibly by grouping related functionality together in a single module. This will not only enhance your documentation experience but could also improve the maintainability of your codebase.
