Getting Started

Azure Functions Language Extensibility Wiki worker.config.json

• git clone https://github.com/Azure/azure-functions-nodejs-worker
• cd azure-functions-nodejs-worker
• npm install
• npm run build
  • Generates protobuf definitions & runs typescript compiler
• npm test

Debugging and Testing

• In the function app you are using to test, add the App Setting in local.settings.json languageWorkers:node:workerDirectory = <path-to-nodejsWorker.js>
  • This configures the functions host to use the development version of the worker
  • You can also configure languageWorkers:node:workerDirectory as an environment variable.
• To debug, add the App Setting in local.settings.json languageWorkers:node:arguments = --inspect-brk
  • You can also configure languageWorkers:node:arguments as an environment variable.

Make sure that languageWorkers:node:workerDirectory and languageWorkers:node:arguments are set correctly. When you start your functions host, you should see your custom path to workerDirectory and any arguments you passed to the node. If it was not set correctly, your output may look like the default output: Starting language worker process:node "%userprofile%\AppData\Roaming\npm\node_modules\azure-functions-core-tools\bin\workers\node\dist/src/nodejsWorker.js" --host 127.0.0.1 --port 5134 --workerId fd9b17c3-8ffb-49f7-a4e3-089a780e7a00 --requestId 14e27374-9395-42d4-a639-bd67e0e770a4 --grpcMaxMessageLength 134217728

Publishing

package.ps1 creates the nuget package for the worker.

It builds and webpacks the generated node files into a bundle. We include several grpc native modules, for x86/x64 versions of windows, osx, linux

The nuget package can be deployed from the appveyor job at: https://ci.appveyor.com/project/appsvc/azure-functions-nodejs-worker
