Environment variable in Node.js (VS Code) is undefined
If you're facing issues with accessing environment variables in Node.js within Visual Studio Code, there are a few potential solutions you can try:
Verify that the environment variable is set correctly: Double-check that the environment variable is correctly set on your system or in your terminal session. You can use the
echo
command (e.g.,echo $VARIABLE_NAME
) to verify the value of the variable.Restart Visual Studio Code: If you have recently set or modified the environment variable, try restarting Visual Studio Code to ensure that it picks up the updated environment.
Use the
dotenv
package: If you're using environment variables defined in a.env
file, make sure you have thedotenv
package installed (npm install dotenv
) and add the following line at the beginning of your Node.js script:javascriptrequire('dotenv').config();
This will load the environment variables from the
.env
file intoprocess.env
.Check launch configuration: If you're debugging your Node.js application using a launch configuration in Visual Studio Code (
launch.json
), make sure that you have the correct environment variables defined in theenv
section of the configuration.json{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Launch Program",
"program": "${workspaceFolder}/app.js",
"env": {
"VARIABLE_NAME": "value"
}
}
]
}
Ensure that the environment variable is defined correctly within the
env
section.
By following these steps, you should be able to access the environment variables within your Node.js application in Visual Studio Code.
