Summary:

I have recreated the example plugin found in the documentation at Writing a Language Service Plugin.

The example works when using 'npm link', but not with relative paths.

I referred to the plugin in tsconfig like this:

"plugins": [{
	"name": "../plugin"
}]

I have also tried to refer to ../plugin/index and ../plugin/index.js, but neither of them works.

Expected behavior:

Be able to refer to the plugin with a relative path.

Actual behavior:

Silently fails without the plugin being loaded.

Commencez par l’exemple lié « Writing a Language Service Plugin » et reproduisez sa configuration de plugin tsconfig en utilisant le chemin relatif ../plugin. Suivez la manière dont cette configuration résout le plugin, puis vérifiez que l’exemple documenté charge le plugin sans npm link et n’échoue plus silencieusement.
