Hyperledger Fabric Golang sdk driver for react-native-hlf-wrapper

A project to generate the required native modules for hyperledger fabric go sdk to be used as a react native module.

Dependencies

Make sure golang`` installed and GO_PATH``` is set

Run the following in the terminal to get the required dependencies

go get github.com/hyperledger/fabric-sdk-go
go get golang.org/x/mobile/cmd/gomobile

Also, navigate to this cloned folder in your terminal and run the following commands in your terminal

go mod init
go mod tidy

Binding the SDK package

Run the following command to bind generate the java code:

Android

gomobile bind -o ./bin/hlfsdk.aar -target=android github.com/bityoga/hlf-driver

This should generate two files, sdk.aar and sdk-sources.jar.

These files should be moved to a new folder called "libs" inside the react native project's android directory. Make sure to add these libs to your android project

IOS

gomobile bind -ldflags "-w" -o ./bin/hlfsdk.framework -target ios github.com/bityoga/hlf-driver

This command removes the debug information, reducing the resulting file size under the GitHub size limit.

Place the generated hlfsdk.framework directory into a new folder called "libs" inside the react native project's ios directory. Make sure to add these libs to your ios project

Functionalities

Only the enroll, query and invoke functionalities are provided. This sdk wrapper is created to be used as native module for react-native. There the idea is that a client mobile application is able to only perform these operations and not any admin operations. Admin operations like channel creation, chaincode installation should be performed by a server side sdk and not a mobile client.

Enroll User: Enrolls a user and stores their crypto materials

go run main/main.go enroll username userpw connection_profile.json

Query Chaincode: Queries a chaincode

go run main/main.go query username connection_profile.json channel_name chaincode_name function_name args,seperated,by,comma

Invoke Chaincode: Invokes a function in the chaincode

go run main/main.go invoke username connection_profile.json channel_name chaincode_name function_name args,seperated,by,comma
