Before you get started with scaffolding your hook's project, ensure that you have the correct environment setup. This will ensure that everyone is on the same page and can run the same commands. Primarily, your environment will consist of node and npm. A tool commonly used to manage various Node.js versions is nvm. This tool allows you to easily switch between different versions of Node.js. You will be using nvm to install the latest long-term support, or LTS, version of Node.js. According to the 

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.2/install.sh | bash

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.2/install.sh | bash

nvm will tell you to close and reopen your terminal, but since it's just appended to your shell's profile, you can just run the following command to reload the profile:

You can check that nvm was properly installed and sourced by issuing the following command:

You should see a list of installed versions of Node.js; by default, there should be at least one installed.

As of this writing, the latest LTS version of Node.js is 18.12.1. The major version of Node 18 was released in April 2022 and will be the active LTS until October 2023. You can install this version of Node.js using the following command:

This will also install npm version 8.19.2.

Since you'll be using this throughout the rest of the course, let's alias it as your default version of Node.js:

This means every time you open up a new terminal, nvm will load Node.js 18.12.1 for you. To double-check that nvm is doing its job, simply open a new terminal and issue:

In the next lesson, you'll begin scaffolding your project.

Before you get started with scaffolding your hook's project, ensure that you have the correct environment setup. This will ensure that everyone is on the same page and can run the same commands. Primarily, your environment will consist of node and npm. A tool commonly used to manage various Node.js versions is nvm. This tool allows you to easily switch between different versions of Node.js. You will be using nvm to install the latest long-term support, or LTS, version of Node.js. According to the [nvm installation documentation](https://github.com/nvm-sh/nvm#installing-and-updating), nvm can be installed using `curl` or `wget`:

```shell
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.2/install.sh | bash
```

or 

```shell
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.2/install.sh | bash
```

nvm will tell you to close and reopen your terminal, but since it's just appended to your shell's profile, you can just run the following command to reload the profile:

```shell
source ~/.zshrc
```

or if you use bash:

```shell
source ~/.bashrc
```

You can check that nvm was properly installed and sourced by issuing the following command:

```shell
nvm list
```

You should see a list of installed versions of Node.js; by default, there should be at least one installed.

As of this writing, the latest LTS version of Node.js is 18.12.1. The major version of Node 18 was released in April 2022 and will be the active LTS until October 2023. You can install this version of Node.js using the following command:

```shell
nvm install 18.12.1
```

This will also install npm version 8.19.2.

Since you'll be using this throughout the rest of the course, let's alias it as your default version of Node.js:

```shell
nvm alias default 18.12.1
```

This means every time you open up a new terminal, nvm will load Node.js 18.12.1 for you. To double-check that nvm is doing its job, simply open a new terminal and issue:

```shell
node -v
```

You should see the following output:

```shell
v18.12.1
```

In summary, you:

-   Installed nvm
-   Installed the latest LTS version 18 of Node.js, version 18.12.1
-   Set version 18.12.1 as your default version of Node to use via `nvm default`

In the next lesson, you'll begin scaffolding your project.
