To connect your app you will need to install:
Node and NPM
If not already installed, install Node & npm, choose the LTS version of your operating system. You can check if you have it installed by checking the version with the following commands:
$ node -v
$ npm -v
The commands should print the versions of Node.js and npm accordingly.
The integrations and tutorials should work with older versions of Node and npm but it has not been tested by our team.
Please remember that the React Native and the ledger packages have been updated since the creation of the documentation and there might be some breaking changes. If you encounter difficulties with more recent packages, you can downgrade to the versions used in the documentation.
