mkdir myapp
cd myapp
```

### Install Express.js Temporarily

Source: https://expressjs.com/en/starter/installing.html/index

```bash
npm install express --no-save
```

### Install Express.js

Source: https://expressjs.com/en/starter/installing.html/index

This command installs the Express.js framework as a dependency for your project. The `--save` flag (which is default in npm 5.0+ and explicit in older versions) adds Express to the `dependencies` section of your `package.json` file.

```bash
npm install express
```

### Initialize npm Project

Source: https://expressjs.com/en/starter/installing.html/index

The `npm init` command initializes a new Node.js project by creating a `package.json` file. This file stores metadata about your project and manages its dependencies. You will be prompted to provide details about your application.

```bash
npm init
```
