如何在 Azure 应用服务上的 npm 脚本中使用 Node -r 标志

Question

I am running a node site on an Azure App Service but it won't start with the following line in my package.json scripts.

   "scripts": {
        ...
        "serve": "node -r dotenv-azure/config dist/server.js",
        ...
    },

The -r flag is required to preload environment variables using dotenv-azure, as per their own instructions... https://www.npmjs.com/package/dotenv-azure

it works absolutely fine on localhost (Windows), it loads the config before starting the server. On Azure App service (windows) however it fails to start the server and I get a 503 error after starting it.

I have tried switching on application logging but because it can't even start the server I get nothing in the logs.

After add httpplatformhandler in web.config file, it works for me. You can download my sample code from github . You will find my web.config file.

Test Steps：

1. Create a sample code.

2. Create .env file.

3. Test result in local.

4. Deploy by git.

After deployed, it also has some error, we should add web.config to solve it.
