Describe the bug
When developing an plugin it is common to symlink your plugin in a test application rather than use a archived tgz file. When such symlink plugin is used inside a NativeScript + VueJs application and the "--bundle" flag is passed to tns run a constant rebuild if the project is triggered. The plugin that is used with symlink has a tsconfig.json file with "declaration": true, this is critical in reproducing the issue.

To Reproduce

• Clone nativescript-picker
• Go to the src directory and run npm run build to build the plugin's code
• Go to its demo-vue directory and run tns run ios --bundle or tns run android --bundle

Expected behavior
After the above steps the demo-vue application is deployed correctly to the device/simulator

Sample project
Can be found here.

Additional context
CLI output:

mcsofamiorkov:demo-vue amiorkov$ tns run ios --bundle

I'm running into the exact same issue while developing my own plugin. the only solution so far was to remove ".ts" files from the webpack "resolve" option.

[rosen-vladimirov]

Hey, sorry for the delayed reply. The problem is caused by having declaration: true in tsconfig.json of the plugin. The demo-vue project is JavaScript and even if you place tsconfig.json at its root, as there are no .ts files in the demo, this tsconfig.json will not be used. As the linked plugin has .ts files, ts-loader uses the tsconfig.json from the src directory. In this tsconfig.json the declaration is set to true, so each change in .ts file produces new .d.ts files. Webpack's watcher detects these new .d.ts files and starts new compilation, which produces new .d.ts files, etc.

There are various ways to resolve this. One of them is to pass declaration: false to ts-loader and that's exactly what I've implemented in the related PR.
Another way is to pass full path to tsconfig.json (the one located in the project), but I've decided that it is not expected to have tsconfig.json in a JavaScript project, so this solution would not resolve all cases.

Hope this clears it out.
