WebDBG

A React Static Web App (SWA) frontend with a containerized Javascript API backend that injests .dmp files and returns analyzed text.

Public Site

This project is hosted publicly on a best effort basis at https://webdbg.rtech.support as a service by the r/Techsupport Discord Server.

Components

• WebDBG
  • Frontend SWA in react.
  • Backend API written in JS that sends and recieves results from the Windows SDK container.
• WinDebug-Container
  • The base container for the API.
  • Windows Core 2022 image containing Windows SDK with only Debugging Tools installed.

SWA

Configure the SWA by copying env.example to .env and configuring appropriately.

• The REACT_APP_API_URL must not end in a trailing slash

Local development

From inside the swa directory run npm start to launch the development server.

Azure deployment method

Configure the Azure deployment by copying template.json.example to template.json and configuring appropriately.

az group create --name <your-resource-group> --location eastus2
az deployment group create --resource-group <your-resource-group> --template-file template.json

Once deployed, the SWA will now be pointed at your repo and is waiting for a build to be submitted. You must create and configure your own GithubAction and repository secrets and variables for this portion of the deployment.

The following Secrets and Variables must be configured under the "Actions" context:

• AZURE_STATIC_WEB_APPS_API_TOKEN
• REACT_APP_API_URL
• REACT_APP_REPO_URL
• REACT_APP_SITE_NAME

API

Local development

On a Windows host with Docker installed and using Windows containers execute the following from inside the api directory to build and launch the WinDebug-Container based API.

docker build -t api . ; docker run --rm -it -p 3000:3000 api

Once launched use REACT_APP_API_URL=http://localhost:3000 in your .env and launch your local development SWA.

PUT endpoint usage
