• INTRODUCTION

IBM has always been a promoter for the
blockchain-oriented solution as well as
architecture. Thats the reason why IBM launched
hyperledger projects in collaboration with Linux.
Hyper ledger has chosen a different path from
others in the blockchain sector. It primarily
concentrates on the private blockchain rather
than public. Broadly there exists a misconception
about hyper ledger project. Most of the people
think its an individual blockchain but in fact,
it's a group of blockchain projects which
pseudonym a hyper ledger. The most widely used
hyperledger project is fabric which is primarily
built for enterprise use-cases. The hyperledger
got huge community support and a wide variety of
tutorials, but still, developers around the world
are struggling to install and instantiate smart
contract. In order to make the developer's job a
little simple, IBM introduced a package extension
for visual studio code ide. The idea behind this
package was vs code- it is a widely accepted
developer ide. So rather than instantly one by
one library in the local system, the IBM
blockchain platform package simplifies and does
that job in a single click. Today Im going to
explain how fabric can be responsive through vs
code.

• How to set up Hyperledger Fabric
• First of all open vs code and create a directory
  where you want to clone the hyper ledger fabric
  images(docker). It may take a while because it
  will download all necessary docker images for the
  network to run. Once you finished downloading all
  docker images, it will generate a folder named
  fabric-samples inside your directory. Enter into
  the directory by cd command and list out the
  folder by ls.

4
Now select the Extension option from the vs
code and enter IBM blockchain platform, It will
show a bunch of extensions, but please go for the
above name and install it
5
Once you click on the install button you'll be
forwarded to an output console and show missing
parameters. If you have followed every
installation dependency correctly you will not
get above window. So install every dependency
like nodejs which is required, you can omit the
optional dependencies. If everything got
installed perfectly, you will be redirected to
new window followed by and new square ico below
extension option.
6
Once you click on the square icon you will get
four small box options namely 1. Smart
contracts 2. Fabric environments 3. Fabric
gateway 4. Fabric wallet Now click on the lets
blockchain option which will populate the four
square boxes with few options.
7
Now click on the local fabric option inside the
fabric environment which will pull all necessary
images and run it as a containers. Once the
connection gets successful, you will see a fully
populated fabric environment. Now right
click on the smart contract option which will
show three options 1. Create project 2. Import
project 3. Package open project As we are new
here, click on the create project option which
will again show 4 options.
8
Select the suitable language based on your
interest, as I choose javascript here, it will
ask for an asset name. Enter a name and click
enter which will ask for path where it want to
save the smart contract. Select the corresponding
folder which we created first. After selecting
the path, it will again show three options.
9
Select the add to workspace option followed by
enter, which will generate smart contract in
your chosen folder.
10
Now go through lib folder and open the
contract.js file, which will be auto populated by
a dummy contract. Now select the square icon
again and click on the install smart contract
option,it will show the name of your
corresponding folder, all you need to do is just
click on the folder name Now the contract
name will appear under the installed contract
list with the name as same as folder name. After
successful installation, we have to instantiate
the contract. Click on the instantiate option
which will again show the name of the installed
smart contract. Just click the enter.
11
Note some of the vs code may ask for more
questions, just click enter for default
choosing. After successful install and
instantiate, the smart contract will appear on
the smart contract list as well as on the fabric
environment list Moreover, we have channel
options available for private transaction between
two parties in the same network. So this is the
IBM extension installation for hyperledger
fabric. For more details stay tuned.
