Fabric REST sample

Prototype sample REST server to demonstrate good Fabric Node SDK practices

The primary aim of this sample is to show how to write a long running client application using the Fabric Node SDK

The REST API is intended to work with the basic asset transfer example

To install the basic asset transfer chaincode on a local Fabric network, follow the Using the Fabric test network tutorial

To build and start the sample REST server, you'll need to download and install an LTS version of node

Clone this repository and change to the fabric-rest-sample/asset-transfer-basic/rest-api-typescript directory before running the following commands

Install dependencies

npm install

Build the REST server

npm run build

Create a .env file to configure the server for the test network (make sure TEST_NETWORK_HOME is set to the fully qualified test-network directory)

TEST_NETWORK_HOME=$HOME/fabric-samples/test-network npm run generateEnv

Start a Redis server

npm run start:redis

Start the sample REST server

npm run start:dev

If everything went well, you can now make REST calls!

For example, check whether an asset exists...

curl -v -X OPTIONS http://localhost:3000/api/assets/asset7

Create an asset...

curl --header "Content-Type: application/json" --request POST --data '{"id":"asset7","color":"red","size":42,"owner":"Jean","appraisedValue":101}' http://localhost:3000/api/assets

Get an asset...

curl -v http://localhost:3000/api/assets/asset7
