watch additional files

tsc watch yarn.lock

Suggestion

add the ability to watch files that are not part of the default set

Use Cases

primary use case for this is to auto restart language server, or a tsc --watch if yarn.lock changes when using pnp since there is no node_modules to watch. currently if a library is removed tsc will actually crash when it goes missing. When a library is added tsc watch needs to be manually restarted.

Examples

I think these should be additive, not replace the existing paths, however I can see adding a new option for additivity, or requiring this to replace existing options. If it replaces the current watch set then it should be well documented how to specify them. If no arguments are provided the behavior of suggested would be use the defaults.

tsc --watch yarn.lock

"compilerOptions": {
    "watch": {
      "paths": ["yarn.lock"],
    },
}

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

Commencez par examiner le point d’entrée de tsc --watch et la gestion par défaut existante de la surveillance des fichiers. L’issue propose des formes en ligne de commande et compilerOptions, mais laisse indéterminées leur interaction et leur additivité ; sa réalisation nécessiterait une interface définie, une implémentation, une documentation et une couverture des tests pour la surveillance des changements de yarn.lock.
