Exercise: Run the client application

Note: This exercise requires the Fabric network and chaincode deployed in the Smart Contract Development exercises to be running.

Let's make sure we can successfully run the client application and get some familiarity with how to use it.

In a terminal window, navigate to the applications/trader-typescript directory. Then complete the following steps:

1. Install dependencies and build the client application.

   npm install
   

2. Set environment variables to point to resources required by the application.

   export ENDPOINT=org1peer-api.127-0-0-1.nip.io:8080
   export MSP_ID=org1MSP
   export CERTIFICATE=../../_cfg/uf/_msp/org1/org1admin/msp/signcerts/org1admin.pem
   export PRIVATE_KEY=../../_cfg/uf/_msp/org1/org1admin/msp/keystore/cert_sk
   

3. Run the getAllAssets command to check the assets that currently exist on the ledger (if any).

   npm start getAllAssets
   

4. Run the transact command to create (and update / delete) some more sample assets.

   npm start transact
   

5. Run the getAllAssets command again to see the new assets recorded on the ledger.

   npm start getAllAssets
   

These application CLI commands represent a simplified application that performs one action per call. Note that real world applications will typically be long running and will make calls to a contract on behalf of user requests.

Optional steps

Try using the create, read and delete commands to work with specific assets.

See the application Readme for details on how to use the commands.
