Development Environment

We have a tool to manage your dev environment easily with some commands. Once you install @worldsibu/convector-tool-dev-env you will have the folowwing commands available in your .bin folder inside the node_modules:

• dev-env-start - Start the docker containers
• dev-env-stop - Stop the docker containers
• dev-env-init - Init de docker containers with two channels, 1 admin user and 3 regular users per org
• dev-env-clean - Remove all the docker containers and the generated chaincode images
• dev-env-restart - Destroy and start your env fresh again
• user-registry - Register admin/users

Basic structures

The development environment you get is made up like this.

Network topology. All the containers provisioned.

Channels. If you are not that familiar with Fabric, channels are the actual ledgers, you may have multiple. If an organization doesn't belong to a channel, there is no way for them to access the data.

Users. Entities of the network that can be used to similate actual users.

User Registry

Users in Fabric can have to main roles, admin users (administrators, with high privileges) or regular users (consumers of the blockchain).

Register Admin

To add new admins, run:

user-registry add-admin [username] [password] [msp] \
  --keystore ./.hfc-key-store \
  --profile ./network-profile.yaml

Register User

To add new regular users, run:

user-registry add-user [username] [admin-username] [msp] \
  --role [role] \
  --affiliation [affiliation] \
  --keystore ./.hfc-key-store \
  --profile ./network-profile.yaml

Include them in your project

To make it easier to manage those commands for your specific project, you can include this in your root package.json. Be sure to have included the basic packages as seen in Getting-Started.

{
  "scripts": {
    "env:init": "./node_modules/@worldsibu/convector-tool-dev-env/scripts/init.sh",
    "env:start": "./node_modules/@worldsibu/convector-tool-dev-env/scripts/start.sh",
    "env:stop": "./node_modules/@worldsibu/convector-tool-dev-env/scripts/stop.sh",
    "env:restart": "./node_modules/@worldsibu/convector-tool-dev-env/scripts/restart.sh",
    "env:clean": "./node_modules/@worldsibu/convector-tool-dev-env/scripts/clean.sh"
  }
}
