This module is installed via npm:

npm install fyers-api

Overview
There is only one class in the package: clientApi. This class is used to retrieve an authorization_code from the server. An authorization_code is valid for 24 hours. With an authorization_code, you can request for user access token. Ideally you only need to create a Session object once every day.
With an access token, you can instantiate rest of the functions in the class.. 

Sample Program

const fyers = require(fyers-api)

For Authentication Process
app_id = 'your_app_id'

app_secret = 'your_app_secret'

let reqBody = { "app_id": app_id, "secret_key": app_secret };

let result = fyers.auth(reqBody)

	The above command returns JSON structured like this:

    {
	'code': 200,
	 'data': {
		'authorization_code':'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJqaGdqZzg3NiQ3ODVidjVANj Q3NTZ2NSZnNyM2OTg3Njc5OHhkIjoiWElHVFVYVjBSSSIsImV4cCI6MTU2MTU5NzM5Ny41NjQxNTV9.Agl-Uus63NforrUEdbG7YUlPcbFXu9hLYm4akGuIBkU'
		},
	 'message': ''
    }
	authorization_code = “your_autherization_code”

	To get the URI

        If he is new user

        url = fyers.generateToken()

        Existing User

		url = fyers.generateToken('user_id') # to get login url for user 

        The Aboove function will return url like this:
        https://api.fyers.in/api/v1/genrateToken?authorization_code=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJqaGdqZzg3NiQ3ODVidjVANjQ3NTZ2NSZnNyM2OTg3Njc5OHhkIjoiWElHVFVYVjBSSSIsImV4cCI6MTU2MTU5NzM5Ny41NjQxNTV9.Agl-UUs63NforrUEdbG7YUlPcbFXu9hLYm4akGuIBkU&appId=Your_app_id"

        Redirect the user to this url.
        After user approve the request access_token will be send to redirect_url given by the client while registering the application. 
      
      Sample result after user approve the request:   

      http://localhost:5000?access_token=gAAAAABc3Sh9QpE5mNx2mSz6vvvT29SAsELqkfbKQKa2977zHw3NdPBhe6jAZCBumHvYUum87j53-AzMEPXMjQw31wkRviZ1TdM5OimgTYWEEorWDmWuHnY=&user_id=FYXXXX


let token = 'your_access_token'
