This demo provides an easy way to test out uPort authorization credentials as well as a beginner setup procedure for nodejs.
Ensure you have an updated version of nodejs and npm installed. Ubuntu repos often contain an old version, so it's recommended to use a more up-to-date repo.
If you already had nodejs installed and need it updated, make sure to sudo apt-get update && sudo apt-get upgrade. Otherwise a sudo apt-get install nodejs npm should be sufficient.
brew install node
Install node from http://nodejs.org/download/ and open the node command prompt.
Assuming nodejs/npm is correctly installed, the next step is to install all the project dependencies, along with yarn.
sudo npm -g install yarn
Finally, install all dependencies with yarn:
yarn
To test your credentials, update lines 6 and 2 of test.js with your credentials from https://appmanager.uport.me/launch/register and run the test script as shown below.
node test.js
This will print a QR code in the console, which you can scan with the UPort mobile app. After the scan, you'll see the authorization payload printed in JSON in the console.
