Problems with npm link'd dependencies

[ralphtheninja]

I have some issues when using npm link from another module into a project using snowpack. When I change some code in the linked module, snowpack notices some change but the linked module is not rebuilt.

I tried instead to modify files directly under node_modules/ folder, but snowpack doesn't notice any changes (I know now after chatting with @fks, that this is normal, just adding it to the conversation).

When modifying the linked module, I don't see a File changed... event. But I notice that the browser page reloads. This is what I meant by some change above.

Something else that I've noticed is that snowpack picks up the same kind of change when doing git operations, like commiting something. For example say I do something like touch foo or even stage the file by doing git add foo, then the browser reloads. Maybe not related at all, but just something that I noticed. It seems to me that snowpack somehow notices changes in the corresponding .git/ folder.

When I change some code in the linked module, snowpack notices some change but the linked module is not rebuilt.

I'm facing exactly this problem. This is my project and the output of npm ls --link=true

$ npm ls --link=true                                                                                           
snowtest@1.0.0 /home/capitaomorte/Source/Javascript/snowtest
└── add-two@ -> /home/capitaomorte/Source/Javascript/add-two

As you can probably guess, add-two is a library that exports a single function addTwo that adds two. But I've changed it now to add 3, 42 and 49 and every time I change that /home/capitaomorte/Source/Javascript/add-two/add-two.mjs file I do see a reload, but the result is not updated in my toy app.

The only thing that effectively rebuilds my code is npx snowpack build. But even npx snowpack dev after that seems to serve a misteriously cached version of addTwo that still just adds 2.

It'd be great to have a idiot-proof tutorial to get npm link and Snowpack working. I can make that tutorial once I understand what's going on.

Facing the same problem... The only thing worked for me so far is

rm -rf node_modules/.cache/snowpack

[joaotavora]

rm -rf node_modules/.cache/snowpack

Precisely. This is the only thing that works as far as I can tell.

There's a pending pull request to fix the issue properly in #2091. I've been using that without any problems. Maybe it will be merged in soon?

As to why this happened, see #429 (comment) and the issue created to track this which #2088.
