Will dump the request data that AWS Lambda receives. This is very similar to services like RequestBin, but will show you the data that you receive from API Gateway and the AWS Lambda systems.
This is a Serverless app, written in Go (Golang), running in AWS Lambda, with API Gateway in front of it, and AWS CloudFront in front of that (for caching).
This is an experiment. Uptime is not guaranteed, and there is no SLA. But all-in-all, it should be reasonably reliable.
NOTE: I've tried to build this in a way that is very cheap to run. But if you find yourself using this more than just occasionally, consider kicking me down a few bucks to offset the cost of running this service. https://cash.me/$rparman
The https://debug.ryanparman.com
hostname is a CloudFront distribution, in front of API Gateway, in front of a Lambda function.
There are two endpoints:
/json
— Send an HTTP request to this endpoint, and the response will be in JSON format./dump
— Send an HTTP request to this endpoint, and the response will be in a custom variable dump format from go-spew. This allows you to see the underlying Golang types.
It responds to GET
, POST
, PUT
, PATCH
, and DELETE
HTTP verbs.

Go (when spoken) or Golang (when written) is a strongly-typed language from Google that "blends the simplicity of Python with the performance of C". Static binaries can be compiled for all major platforms, and many minor ones.
It is recommended that you install Golang using your system's package manager. If you don't have one (or if the version is too old), you can install Golang from its website. Reading the Getting Started documentation is a valuable exercise.
brew update && brew install golang
Golang dependencies are managed with Glide. You should install them before compiling this project.
curl https://glide.sh/get | sh
glide install
GoMetaLinter pulls together many popular linting tools, and can run them on a project.
gometalinter.v2 --install
Serverless is a platform that wraps AWS Lambda and AWS CloudFormation, simplifying the deployment of Lambda apps. Serverless is written in Node.js, so you need to install that first.
I recommend you install the Node Version Manager, and use that to install the latest Node.js and npm. Once that's complete, install serverless
.
npm i -g serverless
This app is small, and is self-contained in main.go
.
By default, it expects to be running in AWS Lambda, receiving HTTP requests coming from API Gateway.
If you are performing local development/testing, run make build
to build for the local platform.
make build
Make sure that you run the linter to catch any issues.
make lint
serverless
uses the same local credentials that the AWS CLI tools and the AWS SDKs use. If you haven't configured those yet, do that first.
Run make package
to build a binary for AWS Lambda. Then, serverless deploy
to deploy the app to your environment.
make package
serverless deploy
