# 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: |
