An architectural layer that manages communication between the application and data source is represented by a repository. The key benefit of this commonly used pattern is that the application does not need to be aware of the data source being used or how it is being used.
\nAs a result, switching to a different data source or implementing structural changes to the current data source is made simpler.<\/p>\n
Steps to implement the repository pattern in Laravel:<\/em><\/p>\n To understand this concept, we will take an example of a blog application. First, create a \u201cRepositories\u201d folder inside the app folder. Then create an Interfaces folder inside the repoRepositoriessitory directory to store all the interfaces.<\/p>\n Now we will create a BlogRepositoryInterface class, which will have three methods:<\/p>\n Now create a BlogRepository class in the Repositories folder to implement the BlogRepositoryInterface. Now bind the BlogRepositoryInterface with the BlogRepository inside the RepositoryServiceProvider class as below:\n
Create Repository Interface:<\/h2>\n
\n
<?php
\nnamespace App\\Repositories\\Interfaces;
\nuse App\\User;
\ninterface BlogRepositoryInterface
\n{
\npublic function allBlogs();
\npublic function getAllByUser(User $user);
\npublic function search($name);
\n}<\/code><\/li>\nInterface implementation with Eloquent:<\/h3>\n
\n<?php
\nnamespace App\\Repositories;
\nuse App\\Models\\Blog;
\nuse App\\User;
\nuse App\\Repositories\\Interfaces\\BlogRepositoryInterface;
\nclass BlogRepository implements BlogRepositoryInterface
\n{
\npublic function allBlogs()
\n{
\nreturn Blog::all();
\n}
\npublic function getAllByUser(User $user)
\n{
\nreturn Blog::where('user_id'. $user->id)->get();
\n}
\npublic function search($name)
\n{
\nreturn Blog::where('title', 'LIKE', '% ' . $name . '%')
\n->get();
\n}
\n}<\/code><\/li>\nRegister a new service provider to use the repository in the entire application:<\/h3>\n
\n<?php
\nnamespace App\\Providers;
\nuse App\\Repositories\\BlogRepository;
\nuse App\\Repositories\\Interfaces\\BlogRepositoryInterface;
\nuse Illuminate\\Support\\ServiceProvider;
\nclass RepositoryServiceProvider extends ServiceProvider
\n{
\npublic function register()
\n{
\n$this->app->bind(
\nBlogRepositoryInterface::class,
\nBlogRepository::class
\n);
\n}
\n}
\n<\/code><\/li>\nAfter that, add that service provider to the Configuration file placed in \u201cconfig\/app.php\u201d:<\/h3>\n
