A paginator that plays nice with the JSON API spec

Latest Version on Packagist GitHub Workflow Status Total Downloads

In a vanilla Laravel application the query builder paginators will listen to page request parameter. This works great, but it does not follow the example solution of the json:api spec. That example expects the query builder paginator to listen to the page[number] and page[size] request parameters.

This package adds a jsonPaginate method to the Eloquent query builder that listens to those parameters and adds the pagination links the spec requires.

Support us

We invest a lot of resources into creating best in class open source packages. You can support us by buying one of our paid products.

We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on our contact page. We publish all received postcards on our virtual postcard wall.

Installation

You can install the package via composer:

composer require spatie/laravel-json-api-paginate

In Laravel 5.5 and above the service provider will automatically get registered. In older versions of the framework just add the service provider in config/app.php file:

'providers' => [
    ...
    Spatie\JsonApiPaginate\JsonApiPaginateServiceProvider::class,
];

Optionally you can publish the config file with:

php artisan vendor:publish --provider="Spatie\JsonApiPaginate\JsonApiPaginateServiceProvider" --tag="config"

This is the content of the file that will be published in config/json-api-paginate.php

<?php

return [

    /*
     * The maximum number of results that will be returned
     * when using the JSON API paginator.
     */
    'max_results' => 30,

    /*
     * The default number of results that will be returned
     * when using the JSON API paginator.
     */
    'default_size' => 30,

    /*
     * The key of the page[x] query string parameter for page number.
     */
    'number_parameter' => 'number',

    /*
     * The key of the page[x] query string parameter for page size.
     */
    'size_parameter' => 'size',

    /*
     * The key of the page[x] query string parameter for cursor.
     */
    'cursor_parameter' => 'cursor',

    /*
     * The name of the macro that is added to the Eloquent query builder.
     */
    'method_name' => 'jsonPaginate',

    /*
     * If you only need to display Next and Previous links, you may use
     * simple pagination to perform a more efficient query.
     */
    'use_simple_pagination' => false,

    /*
     * If you want to cursor pagination, set this to true.
     * This would override use_simple_pagination.
     */
    'use_cursor_pagination' => false,

    /*
     * Here you can override the base url to be used in the link items.
     */
    'base_url' => null,

    /*
     * The name of the query parameter used for pagination
     */
    'pagination_parameter' => 'page',
];

Usage

To paginate the results according to the json API spec, simply call the jsonPaginate method.

YourModel::jsonPaginate();

Of course you may still use all the builder methods you know and love:

YourModel::where('my_field', 'myValue')->jsonPaginate();

By default the maximum page size is set to 30. You can change this number in the config file or just pass the value to jsonPaginate.

$maxResults = 60;

YourModel::jsonPaginate($maxResults);

Cursor pagination

This package also supports cursor pagination, which can be briefly defined by the Laravel Framework as follows:

While paginate and simplePaginate create queries using the SQL "offset" clause, cursor pagination works by constructing "where" clauses that compare the values of the ordered columns contained in the query, providing the most efficient database performance available amongst all of Laravel's pagination methods.

You can find more about cursor pagination in the Laravel Documentation.

If you want to use cursor pagination, you can set the use_cursor_pagination to true in the config file.

It's also possible to modify the pagination parameter in the config file, by modifying the cursor_parameter value.

<?php

return [
    // ..... other config options .....

    /*
     * The key of the page[x] query string parameter for cursor.
     */
    'cursor_parameter' => 'cursor',

    /*
     * If you want to cursor pagination, set this to true.
     * This would override use_simple_pagination.
     */
    'use_cursor_pagination' => true,

    // ..... other config options .....
];
