There are a few steps to invoke a lambda function in a NestJS application:
aws-sdk
package to create an instance of the Lambda service:import * as AWS from 'aws-sdk';
const lambda = new AWS.Lambda({
region: 'us-east-1' // replace with your region
});
invoke
method of the Lambda service, passing in the function name and any payload as parameters:const params = {
FunctionName: 'my-function',
Payload: JSON.stringify({ foo: 'bar' })
};
lambda.invoke(params, (error, result) => {
if (error) {
console.error(error);
} else {
console.log(result.Payload.toString());
}
});
Payload
property of the result object as a base64-encoded string, so you may need to deserialize it before using it.Note that you will need appropriate IAM permissions to invoke the Lambda function, so make sure to set up your AWS credentials correctly.
