(docs)

Install Composer command line tools

npm i -g composer-cli@0.16.3 composer-rest-server@0.16.3 passport-github

Import sample participant identities

cd network
./importIdCards.sh

Enable authentication for API server

Create a new OAuth application on GitHub

  • Application name: composer-rest-server
  • Homepage URL: http://localhost:3000/
  • Application description: OAuth application for the multi-user mode of composer-rest-server
  • Authorization callback URL: http://localhost:3000/auth/github/callback

Run

Start the network

# in 'network' directory
export COMPOSE_PROJECT_NAME=biswas
./deployNetwork.sh

Start the API server

export COMPOSER_PROVIDERS='{
  "github": {
    "provider": "github",
    "module": "passport-github",
    "clientID": "REPLACE_WITH_CLIENT_ID",
    "clientSecret": "REPLACE_WITH_CLIENT_SECRET",
    "authPath": "/auth/github",
    "callbackURL": "/auth/github/callback",
    "successRedirect": "/",
    "failureRedirect": "/"
  }
}'

composer-rest-server -c grower-network-admin@biswas -a true -m true

The API explorer is now located http://localhost:3000/explorer.

Interacting with the network

Import identities into API server

  • Navigate to http://localhost:3000/auth/github and authenticate with GitHub
  • Find the /wallet/import endpoint at the bottom of the list in the API explorer
  • Import the admin identity card from ./network/fabric/id-cards/grower-network-admin/card using the name admin
  • Import the identity cards for the sample network participants from ./network/fabric/id-cards/users using the same endpoint. The names should be the same as the name of the card, i.e. the file distributor.card should be imported as distributor

Add sample data using Postman

  • Navigate to the end-to-end test run documentation and click 'Run in Postman'
  • Select the imported sample-env environment
  • Display your OAuth access token in the explorer by clicking 'show'. Copy this into your Postman environment as the value for the key accessToken
  • Run the requests using the collection runner

View traceability information

  • Copy your OAuth access token into line 9 of ./frontend/src/controllers/api.js
  • Start the web application by running yarn start inside ./frontend
  • Copy the value of bottleID from the Postman environment
  • Navigate to the frontend at http://localhost:3001/
  • Search for the copied bottleID.
