Block explorer for Hyperledger Fabric

Reference

Prerequisites

Microservice mode

UI

CLI usage

Testing

FabEx is inspired by ledgerfsck

Prerequisites

1. Configure config.yaml (it's main config of the Fabex) and connection-profile.yaml (Hyperledger Fabric connection profile)

2. Install and start database (MongoDB or CassandraDB)

   If you choose Mongo:

   1. set initial user name and password in db/mongo-compose/docker-compose.yaml
   2. start container:

   make mongo
   

   If you choose Cassandra:

   make cassandra
   

3. (OPTIONAL) Start your Fabric blockchain network or sample test network with

   make fabric-test
   

Microservice mode

You can start Fabex as standalone microservice with Cassandra blocks storage:

./fabex -task=grpc -configpath=configs -configname=config -enrolluser=true -db=cassandra

or with Mongo storage

./fabex -task=grpc -configpath=configs -configname=config -enrolluser=true -db=mongo

Use fabex.proto as service contract.

Example of GRPC client implementation.

UI

UI is available on port 5252

CLI

Build Fabex executable binary file:

go build

Enroll admin user:

./fabex -enrolluser=true

Save blocks data to db:

./fabex -task=explore -configpath=configs -configname=config -db=cassandra

Also you can start service for fetching blocks in daemon mode:

./fabex -task=explore -configpath=configs -configname=config -db=cassandra

Get transactions of specific block (chain operation):

./fabex -task=getblock -blocknum=14 -configpath=configs -configname=config -db=cassandra

Get all transactions (db operation):

./fabex -task=getall -configpath=configs -configname=config -db=cassandra

You can choose database for data saving and retrieving with -db flag (MongoDB or CassandraDB):

./fabex -task=explore -configpath=configs -configname=config -db=mongo
./fabex -task=explore -configpath=configs -configname=config -db=cassandra
