Install missing TypeScript typings for dependencies in your package.json.
npm install -g typesync
You can also use it directly with npx which will install it for you:
npx typesync
typesync [path/to/package.json] [--dry]
Path is relative to the current working directory. If omitted, defaults to package.json.
Note: typesync only modifies your package.json - you still need to run npm install, or — if drinking the k00laid — yarn.
If --dry is specified, will not actually write to the file, it only prints added/removed typings.
The same is true for --dry=fail, with the additional effect of failing the command in case there are changes.
This is useful for CI scenarios.
