![]() ![]() ![]() The package we are looking to install is cocur/slugify so we will need to retain that name in order to require the package. GitHub uses a vendor/package format to set up identifiers for each package, with Packagist following the same formatting schematic. The Packagist package choices will all have a package name and a vendor name associated with them. We can see that the package cocur/slugify seems to have a respectable download and star number, with a description fitting our needs. However, it is still vital to thoroughly read the descriptions of the packages to make certain the package contains what you require.Īs stated, for this example, we need only to locate a converter from string to slug. The packages with both numbers on the high end are used by more people, meaning that they are more likely to be stable. These results can be sorted based on the ascending or descending order of either of those two numbers. The bottom number shows how many times a package was starred on GitHub. The top number represents the amount of downloads for that particular package. The list will have two numbers in the right column of each listed package. You should query the term “slug” and observe the results: Next, we will need to search for the package that can help us form slugs. ![]() For the sake of this example, we will label it as slugify: We will first need to create a project directory. Let’s presuppose that we have an application with the goal of converting a sentence provided into a slug (a URL-friendly string), something commonly utilized to convert page titles into URL paths. Include the dependency in the composer.json file by running the composer require command.Choose the appropriate dependency package.Look through, Composer’s official package repository to research the appropriate open-source library.Identifying the library needed by the application.The installation of a package with Composer as a dependency for a project can be done as per the following: Other dependencies can be added similarly without needing to manually edit the file. Since creating the file manually is tough to do without running into syntax issues, the file is autogenerated by Composer once you use a require command to add a dependency to your project. Outdated or unstable versions could create backward compatibility problems. This is an essential component of mitigating the use of unstable versions and keeping the project consistent. It will inform it about which dependencies still need to be downloaded, as well as which package versions will be allowed to be installed. This file will serve as a roadmap for Composer. You will need a composer.json file to use Composer for your project. Composer helps to ease the process by tracking the dependencies, simplifying others’ installations of them. This creates a challenge in managing versions and dependencies. Very often, PHP projects rely on external libraries. Next, we’ll look at managing dependencies using Composer. This can be using the php composer-setup.php command, which will create a composer.phar in the current directory, and can be executed using the command. This is similar to the approach used for NPM and is a useful method when the system does not permit the installation of system-wide software. Note: Composer can also be installed locally if you prefer to have separate executables for each project hosted on this server. You can start by updating the packet manager. Prior to installing Composer, you should verify that all of the necessary dependencies are installed. Now, let’s start! Dependencies Installation You can easily install your server by following our tutorial on setting up an Ubuntu server. Before you start the installation, log into your non-root user with privileges. Here is a tutorial on setting up a UFW on Ubuntu and Debian cloud server. In addition, you have to enable your basic firewall and block the nonessential ports. To help you with that take a look at our tutorial on configuring the Linux sudoers file. ![]() In order to be able to follow the tutorial make sure that you have already configured a non-root user with sudo privileges on the local server. In this tutorial, we will walk you through the steps of installing Composer on Ubuntu 18.04. It works by checking and verifying the versions of other packages that are appropriate for project requirements and dependencies and installing them for your convenience. It is primarily leveraged to assist in project dependency updates and installation. Composer is a popular PHP dependency management tool. ![]()
