Node.js Hello World Console Applicationīy using node.js command-line interface, we can create console applications. Here, we will learn both ways to create node.js simple hello world application with examples. In node.js, we can create either console or web applications based on our requirements. Now, we will learn how to create simple node.js hello world application in different ways using node.js command-line interface. Please read and follow the steps in the CONTRIBUTING.md.In previous node.js chapters, we learned what is node.js? and how to setup node.js development environment.

You can also use the Actions on Google Console simulator to test most features and preview on-device behavior. Terminal is just a window running Bash (by default) - you are expecting Bash to suddenly understand JavaScript just by installing node.js on your system.Just say or type, “OK Google, talk to my test app”. You can test your Action on any Google Assistant-enabled device on which the Assistant is signed into the same account used to create this project.Run gactions deploy preview to deploy your project.Run gactions push to push your project.Run gactions login to login to your account.Navigate to sdk/settings/settings.yaml, and replace with your project ID.From the Actions on Google Console, New project > Create project > under What kind of Action do you want to build? > Custom > Blank project.We recommend using MAJOR version 8, npm install -g Run firebase login with your Google account.We recommend installing using nvm for Linux/Mac and nvm-windows for Windows.
