What is is-lambda?
The is-lambda npm package is designed to help developers determine if their code is running in an AWS Lambda environment. This can be particularly useful for writing code that needs to behave differently when run in a Lambda function versus other environments, such as on a local development machine or a different cloud platform. The package provides a simple interface to check the execution environment.
What are is-lambda's main functionalities?
Check if running in AWS Lambda
This feature allows developers to programmatically determine if their code is executing within an AWS Lambda environment. The code sample demonstrates how to use the is-lambda package to check the environment and print a message accordingly.
const isLambda = require('is-lambda');
if (isLambda) {
console.log('Running in AWS Lambda');
} else {
console.log('Not running in AWS Lambda');
}
Other packages similar to is-lambda
lambda-check
Similar to is-lambda, lambda-check provides functionality to check if code is running in AWS Lambda. The main difference may lie in the implementation details or additional features provided by lambda-check, such as more granular checks or support for detecting specific AWS Lambda configurations.
on-aws-lambda
This package also offers a way to detect if the code is executing in an AWS Lambda environment. It might offer a different API or additional utilities compared to is-lambda, such as middleware for popular Node.js frameworks to automatically adjust behavior when running in Lambda.
