For testing purposes, I already have the public key + private key + certificate on hand (can just hardcode it), and I can set up the CA through the connection profile, but how would I invoke a transaction without setting up the filesystem key value store/wallet?
Use the InMemoryWallet
class - see https://fabric-sdk-node.github.io/master/module-fabric-network.InMemoryWallet.html
example:
const credPath = '/home/demo/mynetwork/crypto-material/crypto-config/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp'; const cert = fs.readFileSync(credPath + '/cert.pem').toString(); const key = fs.readFileSync(credPath + '/key.pem').toString(); const inMemoryWallet = new InMemoryWallet(); await inMemoryWallet.import('admin', X509WalletMixin.createIdentity('Org1MSP', cert, key));
