'Azure Static Web Apps: How to set the version of Node.js?

I want to use Node.js v12.x to build and deploy but it uses 14.15.1:

Using Node version:
v14.15.1

Using Npm version:
6.14.8
azureazure-static-web-app


Solution 1:[1]

You can set the desired node.js version via the Azure CLI: az webapp config set --resource-group <resource-group-name> --name <app-name> --linux-fx-version "NODE|12.X"

For more information, see https://docs.microsoft.com/de-de/azure/app-service/configure-language-nodejs?pivots=platform-linux#set-nodejs-version

Solution 2:[2]

If you arrived here wanting to set the Node.js runtime version that is used for your API backend, refer to https://docs.microsoft.com/en-us/azure/static-web-apps/configuration#platform

In summary, you will create a staticwebapp.config.json that sits where your app_location is pointed in your github workflow (typically the root of your project) or any subfolder of app_location

You can then set the runtime like this...

{
  "platform": {
    "apiRuntime": "node:16"
  }
}

At the time of writing, your options are node:12, node:14, node:16. Reference the link above for the most up to date values.\

I'd like to answer the original question as well because I think the accepted answer is wrong. The azure CLI will say that az webapp ... can't find your project because it's a staticwebapp not a webapp.

The solution (and I'm not certain) should be to set the nodeEngines in package.json, like this:

{
  "engines": { 
    "npm": ">=7.0.0",
    "node": ">=16.0.0"
  },
  "dependencies": {
    ...
  }
}

If I'm wrong about this, let me know in the comments and I'll update it.
