Deploy Elm app to Azure Static Website from Github

I've got a website developed with Elm that I am trying to deploy to an Azure Static site through GitHub. The application runs fine locally.

The Elm app is based on the create-elm-app template. To build the app locally I run "elm-app build". On the build step below for "elm-app build" it returns the following error:

/home/runner/work/_temp/41853d70-541c-48ef-9f63-fe2f1c27dd9c.sh: line 1: elm-app: command not found
Error: Process completed with exit code 127.

The yaml file that I've written is below.:

    branches:
      - dev
  pull_request:
    types: [opened, synchronize, reopened, closed]

    @Dale Godfredson Since Elm uses the Node.js toolchain, you can add a package.json with the proper dev dependencies and build scripts:

    // package.json  
    {  
      // ...  
      
      "scripts": {  
        "build": "elm-app build"  
      },  
      "devDependencies": {  
        "create-elm-app": "^5.22.0"  
      }  
    }  
    

    You can use the standard Azure/static-web-apps-deploy@v1 action with these settings:

    app_location: "/" # App source code path  
    api_location: "" # Api source code path - optional  
    output_location: "build" # Built app content directory - optional  
    

    Take a look at this sample: https://github.com/anthonychu/20210815-test-elm

    You can also build the app separately, like you've attempted to do. Looks like the error you're getting was caused by line 57:

    run: npm install create-elm-app  
    

    It should be installed globally:

    run: npm install create-elm-app -g  
    

    In addition, because you're building the app in a separate step using elm-app build, you need to set up the Azure/static-web-apps-deploy@v1 action differently:

    app_location: "build" # App source code path  
    api_location: "" # Api source code path - optional  
    skip_app_build: true
