Mapbox configuration is not working. Can not pass access token-CodePudding

I'm trying to implement geocoding to my express app and I decided to use MapBox client API. However when I tried to configure it, it's still throwing following error. Please help me

Error: Cannot create a client without an access token
    at NodeClient.MapiClient (D:\NODE COURSE\Colt Steele\DerpCamp\node_modules\@mapbox\mapbox-sdk\lib\classes\mapi-client.js:25:11)
    at new NodeClient (D:\NODE COURSE\Colt Steele\DerpCamp\node_modules\@mapbox\mapbox-sdk\lib\node\node-client.js:7:14)

    at Object.<anonymous> (D:\NODE COURSE\Colt Steele\DerpCamp\src\controllers\CampgroundController.js:6:18)

Here is my configuration

const Geocoding = require('@mapbox/mapbox-sdk/services/geocoding')
const map_token = process.env.MAPBOX_TOKEN
const geocoder = Geocoding({accessToken: map_token})

VERY IMPORTANT NOTE

There is no space between MAPBOX_TOKEN and my actual api key in my dev.env file.

CodePudding user response：

If you're running the application locally, process.env will return undefined. This issue can be resolved using the dotenv package.

Installation:

npm install dotenv --save

Example usage:

const dotenv = require("dotenv"); // Define the dotenv package
dotenv.config(); // Call the config function

The config function only needs to be called in the main file (commonly called index.js) and will allow process.env to work throughout the project.
