This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@ledgerhq/hw-transport-node-hid-singleton) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

@ledgerhq/hw-transport-node-hid-singleton
Allows to communicate with Ledger Hardware Wallets.
[Node]/Electron (HID) – uses node-hid and node-usb. Keep transport opened and re-use it as a singleton, one device at a time on a computer but more robust implementation.
Are you adding Ledger support to your software wallet?
You may be using this package to open a USB connection between your desktop application and the device.
For a smooth and quick integration:
- See the developers’ documentation on the Developer Portal and
- Go on Discord to chat with developer support and the developer community.
