Choose between Laravel Sanctum Cookie-Based Vs Token Based and Laravel Sanctum Token Based vs Laravel Passport

 Laravel Sanctum is a package that offers both cookie-based and token-based authentication for Laravel applications: 

Cookie-based authentication

This is a good choice for traditional web applications, especially when the front-end and API are on the same domain. Sanctum uses Laravel's built-in cookie-based session authentication services, which provide CSRF protection and session authentication. This approach is ideal for single-page applications (SPAs) that need to communicate with a Laravel API. 

Token-based authentication

This is a more secure and scalable option than cookie-based authentication. Sanctum can be used to generate and manage API tokens, authenticate users, and protect API routes. This approach is more suitable for applications that need fast authorization or more interaction between the client and server. 

Here are some other considerations when choosing between cookie-based and token-based authentication:

Domain

If the front-end and API are on different domains, cookie-based authentication may not be suitable.

Third-party API consumption

If the application involves third-party API consumption, you'll need to decide between Passport and Sanctum for API token authentication.

OAuth2

If the application requires the full range of OAuth2 features, Passport is the right choice.

Install Maven in Mac OSX

to install maven in Mac OSX, the easiest way is to use Homebrew

OR using the following steps:

• Download maven from https://maven.apache.org
• unzip the apache maven zip file into a location when you fix /User/XXX/Desktop/dev/apache-maven-X.X.X
• then you would need to add the maven folder into your user's MacOSX path using vi or other text editor tools

            shell> vi ~/.bash_profile

file content

export M2_HOME=/path/to/your/maven/folder .  (e.g: /User/XXX/Desktop/dev/apache-maven-X.X.X)

export PATH=$PATH:$M2_HOME/bin

• save the file by press "ESC" button, then type this command -> ":wq!"
• you would need to refresh the system PATH using following command

            shell> source ~/.bash_profile

• after that, type shell> mvn --version
