Laravel CSV Response Macro

A lightweight Laravel package that adds a response macro for streaming CSV data directly to the browser, optimized for memory efficiency and designed to handle large datasets with ease.

Installation

You can install the package via Composer. Run the following command in your terminal:

composer require kfoobar/laravel-csv-response

After installing the package, publish the configuration file using the Artisan command:

php artisan vendor:publish --tag=csv-response-config

This will create a csv-response.php file in your config directory, where you can customize the package settings.

How to Use

return response()->csv(
    rows: [], 
    options: [],
    inline: true // false = force download
);

Display CSV Inline

To render the CSV directly in the browser:

$rows = Product::all()
    ->map(function (Product $product) {
        return [
            $product->sku,
            $product->name,
            $product->price,
        ];
    })
    ->toArray();

return response()->csv($rows, inline: true);

Download the CSV

To force the CSV file to download:

$rows = Product::all()
    ->map(function (Product $product) {
        return [
            $product->sku,
            $product->name,
            $product->price,
        ];
    })
    ->toArray();

return response()->csv($rows, inline: false);

Using Options

You may customize the CSV output using the options parameter:

$rows = Product::all()
    ->map(function (Product $product) {
        return [
            $product->sku,
            $product->name,
            $product->price,
        ];
    })
    ->toArray();

$options = [
    'delimiter' => ',',
    'filename'  => 'catalog.csv',
    'headers'   => ['sku', 'name', 'price'],
];

return response()->csv($rows, $options, inline: false);

You can also include the headers directly as the first row in the $rows array if you prefer not to define them in the headers option.
