Laravel 7 Composer Install

Introduction

The composer install command is used in Laravel 7 to install the project dependencies specified in the composer.json file. Composer is a dependency management tool for PHP that helps in managing and resolving package dependencies required by the project.

Command Syntax

To execute the composer install command, open the command-line interface (CLI) and navigate to the root directory of your Laravel 7 project. Then run the following command:

composer install

Description

The composer install command reads the composer.json file and installs all the packages and dependencies listed in it. It installs the exact versions specified in the file, ensuring that all the project requirements are met.

During the installation process, Composer creates a vendor directory where it installs all the required packages. It also generates the composer.lock file, which locks down the exact version of each package installed, ensuring consistency across different environments.

If the composer.lock file already exists when running composer install, Composer will install the dependencies as specified in the lock file without checking for newer versions. This allows for consistent deployments, as all environments will use the exact same package versions.

Usage Examples

• Install project dependencies using composer install:

  composer install
  

Conclusion

The composer install command is an essential part of Laravel 7 development. It helps in managing and installing project dependencies as defined in the composer.json file, ensuring consistent package versions across different environments. Make sure to run composer install after cloning a Laravel project or when adding new dependencies to an existing project.
