This repository contains the AWS Lambda Runtime for the BoxLang language. This runtime allows you to run BoxLang code in AWS Lambda functions. The runtime is built using the AWS Lambda Custom Runtime API and the BoxLang interpreter. You can find the full docs here: https://boxlang.ortusbooks.com/getting-started/running-boxlang/aws-lambda
BoxLang is a modern dynamic JVM language that can be deployed on multiple runtimes: operating system (Windows/Mac/*nix/Embedded), web server, lambda, iOS, android, web assembly, and more. BoxLang combines many features from different programming languages, including Java, ColdFusion, Python, Ruby, Go, and PHP, to provide developers with a modern and expressive syntax.
BoxLang has been designed to be a highly adaptable and dynamic language to take advantage of all the modern features of the JVM and was designed with several goals in mind:
- Be a rapid application development (RAD) scripting language and middleware.
- Unstagnate the dynamic language ecosystem in Java.
- Be dynamic, modular, lightweight, and fast.
- Be 100% interoperable with Java.
- Be modern, functional, and fluent (Think mixing CFML, Node, Kotlin, Java, and Clojure)
- Be able to support multiple runtimes and deployment targets:
- Native OS Binaries (CLI Tooling, compilers, etc.)
- MiniServer
- Servlet Containers - CommandBox/Tomcat/Jetty/JBoss
- JSR223 Scripting Engines
- AWS Lambda
- Microsoft Azure Functions (Coming Soon)
- Android/iOS Devices (Coming Soon)
- Web assembly (Coming Soon)
- Compile down to Java ByteCode
- Allow backward compatibility with the existing ColdFusion/CFML language.
- Great IDE, Debugger and Tooling: https://boxlang.ortusbooks.com/getting-started/ide-tooling
- Scripting (Any OS and Shebang) and REPL capabilities

To use it, you need to create a Lambda function and specify Java 21 as the runtime. The class that executes your BoxLang code is ortus.boxlang.runtime.aws.LambdaRunner. By convention it will execute a Lambda.bx file in the root (/var/task/Lambda.bx) of the Lambda function, via the run() method. The method signature can look like this:
// Lambda.bx
class{
function run( event, context, response ){
// Your code here
}
}- The
eventparameter is the event data that is passed to the Lambda function as aStruct. - The
contextparameter is the context object that is passed to the Lambda function. This matches the AWS Lambda context object:com.amazonaws.services.lambda.runtime.Context. - The
responseparameter is the response object that is passed to the Lambda function.
The response object is a Struct that you can use to set the response data. The response object has the following keys:
statusCode: The HTTP status code for the response.headers: AStructof headers to send in the response.body: The body of the response, which can be anything.
The BoxLang lambda runner will return the response object as the response to the Lambda function as a JSON object.

sam local invoke bxFunction --event=workbench/sampleEvents/api.json
sam local invoke bxFunction --event=workbench/sampleEvents/event.json
sam local invoke bxFunction --event=workbench/sampleEvents/api.json --debug
sam local invoke bxFunction --event=workbench/sampleEvents/event.json --debug
If you don't want to use the convention of Lambda.bx then you can setup an environment variable called BOXLANG_LAMBDA_CLASS with the full path to the BoxLang class that will execute your code. The class must have a run() method that matches the signature above.
You can enable debug mode by setting the environment variable BOXLANG_LAMBDA_DEBUG to true. This will output debug information to the Lambda logs.
Here is an example of a simple Lambda function that returns a Hello World response:
// Lambda.bx
class{
function run( event, context, response ){
// response.statusCode = 200; set by default
response.headers = {
"Content-Type" : "text/plain"
};
response.body = "Hello World";
}
}However, if you don't even want to deal with the response struct, you can just use a return and whatever you return will be placed for you in the response.body.
// Lambda.bx
class{
function run( event, context ){
return "Hello World";
}
}In order to deploy your function to AWS Lambda, you need to package the runtime and your BoxLang code into a zip file. The zip file should contain the following structure:
+ Lambda.bx
/lib
+ boxlang-aws-lambda-1.0.0-all.jar
