Mindoro State University College of Computer Studies COMPOSER Prepared by: LEE-MAR M. ARCON Instructor I E-mail Address: [email protected] Mobile Number: +639511177784 Bachelor of Science in ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2  College of College of Computer Computer Learning Objectives Click to edit Studies Studies Master title style At the end of the lesson, the learners should be able to: Understand the purpose and significance of version control systems in software development. Learn about Git as a distributed version control system and GitHub as a popular platform for hosting Git repositories. ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2 TOPIC: COMPOSER  College of College of Computer Computer Learning Objectives Click to edit Studies Studies Master title style At the end of the lesson, the learners should be able to: Familiarize yourself with common Git commands such as git init, git add, git commit, git pull, git push, and git status. Learn how to clone an existing Git repository from a remote source (e.g., GitHub) to your local machine. ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2 TOPIC: COMPOSER  College of College of Computer Computer COMPOSER Click to edit Studies Studies Master title style Composer is a dependency management tool specifically designed for PHP. It streamlines the process of installing, updating, and managing libraries or packages within PHP projects. Unlike system-wide package managers, Composer manages dependencies on a per-project basis, allowing each project to have its own set of dependencies. ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2 TOPIC: COMPOSER  College of College of Computer Computer COMPOSER FEATURES Click to edit Studies Studies Master title style  Dependency Management - Composer automatically resolves and installs dependencies for PHP projects, ensuring that all necessary packages are downloaded, and compatible versions are selected based on project requirements. ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2 TOPIC: COMPOSER  College of College of Computer Computer COMPOSER FEATURES Click to edit Studies Studies Master title style  Automatic Loading with Autoloader - Composer provides an autoloader to automatically include and use installed packages in your project without manually writing require or include statements.  Package Discovery and Installation - With Packagist as the default repository, Composer allows you to discover, install, and update open-source packages for various PHP libraries and frameworks ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2 TOPIC: COMPOSER  College of College of Computer Computer COMPOSER FEATURES Click to edit Studies Studies Master title style  Semantic Versioning Compatibility - Composer uses semantic versioning to manage package versions, allowing you to specify version constraints like exact, minimum, or range of versions that fit your project's needs.  CLI Commands - Composer provides a range of CLI commands such as composer install, composer update, and composer require to manage packages, update dependencies, and install libraries with ease. ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2 TOPIC: COMPOSER  College of College of Computer Computer COMPOSER FEATURES Click to edit Studies Studies Master title style  Development vs. Production Dependencies - Composer allows you to specify require for production dependencies and require-dev for development-only dependencies. ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2 TOPIC: COMPOSER  College of College of Computer Computer COMPOSER.JSON Click to edit Studies Studies Master title style Composer.json file is a configuration file that defines the dependencies, project metadata, and various configurations for a PHP project managed by Composer. ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2 TOPIC: COMPOSER  College of College of Computer Computer COMPOSER.LOCK Click to edit Studies Studies Master title style Composer.lock an essential part of managing dependencies in a Composer- based PHP project. It serves as a record of the exact versions of each dependency that were installed at the time composer install was last run. ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2 TOPIC: COMPOSER  College of College of Computer Computer INCLUDING DEPENDENCIES Click to edit Studies Studies Master title style require - Lists the packages and their versions required for the project to run. require-dev - Specifies dependencies only needed for development and testing purposes. ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2 TOPIC: COMPOSER  College of College of Computer Computer PACKAGE VERSIONING Click to edit Studies Studies Master title style Laravel 11.31.0  Major version - indicates that there are backward- incompatible changes.  Minor version - indicates the addition of new features that are backward-compatible with the previous version.  Patch version - indicates backward-compatible bug fixes. Typically used for resolving bugs, fixing security vulnerabilities, or making minor improvements that don’t change the existing functionality. ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2 TOPIC: COMPOSER  College of College of Computer Computer COMPOSER VERSIONING Click to edit Studies Studies CONSTRAINTS Master title style Caret (^) - Allows updates that do not break compatibility. For instance, ^1.2 allows updates up to (but not including) 2.0. Tilde (~) - Allows updates within a specific version. For example, ~1.2.3 would allow updates up to but not including 1.3. Wildcard (*) - Broad version matching, e.g., 1.* matches any 1.x version. Exact Versions - Specify an exact version, like 1.2.3, to restrict updates. ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2 TOPIC: COMPOSER  College of College of Computer Computer COMPOSER BASIC COMMANDS Click to edit Studies Studies Master title style  composer install - Installs all packages listed in composer.json.  composer update - Updates all packages to the latest version according to the constraints in composer.json.  composer require - Installs a specific package and updates composer.json.  composer remove - Uninstalls a package and removes it from composer.json. ITE 413 : INTEGRATIVE PROGRAMMING AND TECHNOLOGIES 2 TOPIC: COMPOSER  College of College of Computer Computer COMPOSER ADVANCE COMMAND Click to edit Studies Studies Master title style  composer dump-autoload: Regenerates the autoload files, useful if you add custom classes.  composer show - Lists all installed packages.  composer outdated - Shows packages that have newer versions available.  composer validate - Checks composer.json for errors.
