Gatsby - Introduction and Installation

What is Gatsby?

Gatsby is an open-source framework built on top of React and Node.js that simplifies the process of creating modern websites and web applications. It pre-renders your website for speed, security, and scalability, while still allowing for dynamic elements.

Installing Gatsby

Gatsby can be installed in your computer by running the following code in the Windows Powershell (run as administrator) npm install -g gatsby-cli (-g here stands for global installation)

Upon doing that you might get this output

PS C:\Windows\system32> npm install -g gatsby-cli
changed 318 packages in 5s
63 packages are looking for funding
run `npm fund for details

After this, enter gatsby --version to verify whether gatsby CLI has been installed on your computer or not.

Upon doing that you might get this output

PS C:\Windows\system32> gatsby --version

Gatsby CLI version: 5.13.3

However, there might be a case that you might be getting this result instead of the above one

PS C:\Windows\system32> gatsby --version
gatsby File C:\Users\joel1\AppData\Roaming\npm\gatsby.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170. At line:1 char:1
+gatsby --version
+ CategoryInfo
: SecurityError: (:) [], PSSecurityException
+ FullyQualifiedErrorId : UnauthorizedAccess

In that case, follow these steps in the powershell:

1. Enter Set-ExecutionPolicy RemoteSigned -Scope CurrentUser in the powershell.
2. On entering that you will be prompted to confirm the change. Type Y and press Enter.
3. To verify the change enter Get-ExecutionPolicy -List.

The above changes should ensure that gatsby CLI is ready to run on your PC.

Enter gatsby --version to verify the installation.
