How to add the js files in Ionic3

Hi

I downloaded MCS Cordova SDK from Oracle MCS and I extracted it and used the files in my Ionic3 application.While I am using the oracle_config fille I am getting that mcs name is not present.

var mcs_config = {
  "logLevel": mcs.LOG_LEVEL.INFO,
  "logHTTP": true,
  "mobileBackends": {
    "YOUR_BACKEND_NAME": {
      "default": true,
      "baseUrl": "YOUR_BACKEND_BASE_URL",
      "applicationKey": "YOUR_BACKEND_APPLICATION_KEY",
      "analytics": {
        "location": true
      },
      "authorization": {
        "basicAuth": {
          "backendId": "YOUR_BACKEND_ID",
          "anonymousToken": "YOUR_BACKEND_ANONYMOUS_TOKEN"
        },
        "oAuth": {
          "clientId": "YOUR_CLIENT_ID",
          "clientSecret": "YOUR_ClIENT_SECRET",
          "tokenEndpoint": "YOUR_TOKEN_ENDPOINT"
        },
        "facebookAuth":{
          "facebookAppId": "YOUR_FACEBOOK_APP_ID",
          "backendId": "YOUR_BACKEND_ID",
          "anonymousToken": "YOUR_BACKEND_ANONYMOUS_TOKEN"
        },
        "ssoAuth":{
          "clientId": "YOUR_CLIENT_ID",
          "clientSecret": "YOUR_ClIENT_SECRET",
          "tokenEndpoint": "YOUR_TOKEN_ENDPOINT"
        },
        "tokenAuth":{
          "backendId": "YOUR_BACKEND_ID"
        }
      }
    }
  }
};

What exact are you getting?
What code is causing the error?

Here i got the variable from mcs sdk and i kept in provider but its showing mcs name was not present.I need to keep some JS files in app which we got through mcs sdk.So i need to place the files and I placed as they given in www folder.Is it correct to place the mcs.js files in which i mentioned above,Please let me knoe if any answer.

No. The www folder should be treated as the property of the build system, which can and will blow away any changes you make there. Look into the options for customizing how app-scripts works.
