+# Articonf bank Node App
+
+# Requirements
+
+1. Bityoga fabric sdk should be up and running
+2. Node version

+   - Tested with v11.0.0
+
+# Run Instructions
+
+1. ## Clone this repository
+
+   - git clone https://github.com/bityoga/articonf-bank-app.git

+# Fabric SDK Adaptor
+
+Node sdk examples to interact with bityoga fabric set up
+
+# Requirements
+  1. Bityoga fabric sdk should be up and running
+  2. Node version
+     - Supports node version >=8
+     - Tested with v8.10.0
+
+# Run Instructions
+  1. ## Clone this repository into your app directory
+      - git clone https://github.com/bityoga/fabric_node_sdk_helper.git
+    
+  2. ## Update your app's package.json
+      - Edit your app's **package.json with the "fabric_node_sdk_helper/package.json"** found in this repository.
+   
+  3. ## Run npm install
+      - ####  Set node version
+          -  nvm use node v8.9.0   (using nvm)
+      - npm install
+      
+  3. ## Update ip address in 'fabric_node_sdk_helper/network_profile.json'
+      - **update the url ip addresses of orderer, peer2, orgca, tlsca (4 places).**
+      - update it with your prime manager's ip address
+      
+  4.  ## Retrieve hyperledger fabric tls certificates of 'orderer' and 'peer2'
+      #### Through shell script - needs ssh permission
+         - cd fabric_node_sdk_helper/
+        - In 'fabric_node_sdk_helper/get_tls_certificates.sh' Replace **IP_ADDRESS="178.62.207.235"** with your fabric prime manager's ip address
+        - **Execute  Command :** bash get_tls_certificates.sh
+      #### (OR) Through Manual scp commands - needs ssh permission
+        - Replace ipaddress in the below scp commands with your fabric prime manager's ip address.
+        - scp -r root@178.62.207.235:/root/hlft-store/orderer/tls-msp/tlscacerts/tls-tlsca-7054.pem ./fabric_node_sdk_helper/hlft-store/orderer/tls-msp/tlscacerts/tls-tlsca-7054.pem
+        - scp -r root@178.62.207.235:/root/hlft-store/peer2/tls-msp/tlscacerts/tls-tlsca-7054.pem ./fabric_node_sdk_helper/hlft-store/peer2/tls-msp/tlscacerts/tls-tlsca-7054.pem
+        
+      #### (OR) Manually edit the following two files - no need of ssh permission
+        - fabric_node_sdk_helper/hlft-store/orderer/tls-msp/tlscacerts/tls-tlsca-7054.pem
+        - fabric_node_sdk_helper/hlft-store/peer2/tls-msp/tlscacerts/tls-tlsca-7054.pem
+         
+        
+   5. ## Enroll admin
+        - #### Call this function "once" when your app starts.
+        - When this function is called, a **wallet** directory will be created in the current directory
+        - Admin user will be enrolled and the certificates will availalble in **wallet** directory
+        - If fabric certificates are changed in future, this wallet directory should cleaned, and this function must be called again to get the new certificates
+        - check wallet directory
+           - a directory named 'admin' will be available
+              - certificates for admin will be available under this directory.
+        - sample : 
+          ``` Javascript
+           // import fabric node sdk helper functions
+          const enrollAdmin = require('./fabric_node_sdk_helper/enrollAdmin');
+
+          async function main() {
+              admin_enroll_status = await enrollAdmin();
+              console.log(admin_enroll_status);
+          }
+
+          main();
+          ```
+
+   6. ## Register user
+        - sample : 
+          ``` Javascript
+           // import fabric node sdk helper functions
+          const registerUser = require('./fabric_node_sdk_helper/registerUser');
+
+          app.post('/register', async (req, res) =>  {
+    
+            let user_name = req.body.uname;
+            let user_password = req.body.psw;
+            let user_role = "client";
+
+
+            let register_status = await registerUser(user_name,
+                                                    user_password,
+                                                    user_role);
+
+            let response = {
+                            status:register_status
+                       };
+            res.json(response);
+          });
+          ```
+        - check wallet directory
+           - a directory with the name of the 'registerd user name' will be available
+              - certificates for the registerd user  will be available under this directory.
+    
+   7. ## Query a chaincode
+        - sample : 
+          ``` Javascript
+           // import fabric node sdk helper functions
+          const querychaincode = require('./fabric_node_sdk_helper/query');
+
+          app.post('/query', async (req, res) =>  {
+
+            let user_name = req.body.uname;
+
+            let CHANNEL_NAME  = "appchannel";
+            let CHAIN_CODE_NAME = "carcc";
+            let CHAIN_CODE_FUNCTION_NAME = "listCars";
+             
+            // Without Arguments
+            let query_result = await querychaincode(user_name,CHANNEL_NAME,CHAIN_CODE_NAME, CHAIN_CODE_FUNCTION_NAME);
+            // With Arguments
+            let query_result = await querychaincode(user_name,CHANNEL_NAME,CHAIN_CODE_NAME, CHAIN_CODE_FUNCTION_NAME , "a");
+
+            let response = {
+                            "status":"success",
+                            "data":query_result
+                       };
+            console.log(response);
+            res.json(response);
+          });
+          ```
+        
+   8. ## Invoke a chaincode
+        - sample : 
+          ``` Javascript
+           // import fabric node sdk helper functions
+          const invokechaincode = require('./fabric_node_sdk_helper/invoke');
+
+          app.post('/invoke', async (req, res) =>  {
+
+            let user_name = req.body.uname;
+            let car_license_plate = req.body.car_license_plate;
+
+            let CHANNEL_NAME  = "appchannel";
+            let CHAIN_CODE_NAME = "carcc";
+            let CHAIN_CODE_FUNCTION_NAME = "listCars";
+
+            let invoke_result = await invokechaincode(user_name, 
+                                            CHANNEL_NAME, 
+                                            CHAIN_CODE_NAME, 
+                                            CHAIN_CODE_FUNCTION_NAME,
+                                            car_license_plate,
+                                            "Opel","Corsa","Light Blue","7","2050","1");
