Filesystem

The v2 filesystem APIs operate on absolute paths. Use fs/watch when a client needs to invalidate UI state after a file or directory changes.

{ "method": "fs/watch", "id": 54, "params": {
  "watchId": "0195ec6b-1d6f-7c2e-8c7a-56f2c4a8b9d1",
  "path": "/Users/me/project/.git/HEAD"
} }
{ "id": 54, "result": { "path": "/Users/me/project/.git/HEAD" } }
{ "method": "fs/changed", "params": {
  "watchId": "0195ec6b-1d6f-7c2e-8c7a-56f2c4a8b9d1",
  "changedPaths": ["/Users/me/project/.git/HEAD"]
} }
{ "method": "fs/unwatch", "id": 55, "params": {
  "watchId": "0195ec6b-1d6f-7c2e-8c7a-56f2c4a8b9d1"
} }
{ "id": 55, "result": {} }

Watching a file emits fs/changed for that file path, including updates delivered by replace or rename operations.
