How can I use environment variables in AWS Lambda with the AWS SDK?

You can set environment variables in AWS Lambda through the AWS Management Console, AWS CLI, or SDK. Do you need help with a specific method?

Yes, can you show me how to do it using the AWS SDK for JavaScript?

Sure! You can use the updateFunctionConfiguration method to set environment variables. Here's a sample code snippet:

const AWS = require('aws-sdk');
const lambda = new AWS.Lambda();

const params = {
  FunctionName: 'your-function-name',
  Environment: {
    Variables: {
      KEY: 'value'
    }
  }
};

lambda.updateFunctionConfiguration(params, function(err, data) {
  if (err) console.log(err, err.stack);
  else console.log(data);
});

Would you like to know more about accessing these variables in your Lambda function?

Yes, how do I access those environment variables in my Lambda function?

You can access environment variables in your Lambda function using process.env. For example:

exports.handler = async (event) => {
  const value = process.env.KEY;
  console.log('The value of KEY is:', value);
};
