| # Create your Node.js Application | |
| In this step, you will create a very simple Node.js application that can be deployed to the Cloud. You will use an application generator to quickly scaffold out the application from a terminal. | |
| > **Tip:** If you have already completed the [Node.js tutorial](/docs/nodejs/nodejs-tutorial.md), you can skip ahead to [Create the Website](/tutorials/nodejs-deployment/create-website.md). | |
| ## Install the Express Generator | |
| [Express](https://www.expressjs.com) is a very popular framework for building and running Node.js applications. You can scaffold (create) a new Express application using the [Express Generator](https://expressjs.com/en/starter/generator.html) tool. The Express Generator is shipped as an npm module and installed by using the npm command line tool `npm`. | |
| ```bash | |
| $ npm install -g express-generator | |
| ``` | |
| The `-g` switch installs the Express Generator globally on your machine so you can run it from anywhere. | |
| ## Scaffold a New Application | |
| We can now scaffold a new Express application called `myExpressApp` by running: | |
| ```bash | |
| $ express myExpressApp --view pug --git | |
| ``` | |
| The `--view pug --git` parameters tell the generator to use the [pug](https://pugjs.org/api/getting-started.html) template engine (formerly known as `jade`) and to create a `.gitignore` file. | |
| To install all of the application's dependencies, go to the new folder and run `npm install`. | |
| ```bash | |
| $ cd myExpressApp | |
| $ npm install | |
| ``` | |
| ## Run the Application | |
| Last, let's ensure that the application runs. From the terminal, start the application using the `npm start` command to start the server. | |
| ```bash | |
| $ npm start | |
| ``` | |
| Now, open your browser and navigate to [http://localhost:3000](http://localhost:3000), where you should see something like this: | |
