+This is based on the [Getting Started guide for Nodejs](https://docs.dagger.io/sdk/nodejs/783645/get-started#step-5-test-against-multiple-nodejs-versions)

+A simple react app is created with `create-react-app` which is built and tested by `build.js` or `build.ts`.
+
+Run:
+
+`npm install`
+
+and then:
+
+`node --loader ts-node/esm ./build.ts`
+
+or
