About it

This library is a minimalist on demand and immutable PDF generator for Laravel. It aims to keep a small friction once you need to generate a printable file using a intuitive public API.

Simple PDF is shipped with a default template that you will be able to use to frame your next PDF files. You can see its layout here

Installation

This library uses Composer to manage its dependencies. So, before using it, make sure you have it installed in your machine. Once you have done this, you will be able to pull this library in by typing the following command in your terminal.

composer require gocanto/laravel-simple-pdf

Default template implementation

Using the default template is the easiest way to get started. Like so:

use Gocanto\SimplePDF\Builder;
use Gocanto\SimplePDF\TemplateContext;

Route::get('default-template', function (Builder $builder) {

    $context = TemplateContext::make([
        'title' => 'foo',
        'name' => 'bar',
        'content' => '<h1>Some amazing content!</h1>',
    ]);

    $builder->make($context);

    return $builder->render();
});

What's going on here ?

  • First of all, we imported the Builder and the Template Context objects; you can think about them as the manager to generate your PDF files. For instance, the Builder is the one on charge of creating the Stream File we will be rending on demand while the another one holds the data to be display within the default template.

  • Second of all, we created the TemplateContext object with the desired data to be shown in our PDF file. The context object is a simple value object that holds some handy methods to manipulate the given array within our blade files. See more

  • Lastly, we invoke the make method passing in our context object and finish by returning with the render functionality.

Custom template implementation

This implementation is done out of the same API, but it has a bit of configuration on the top. Like so:


use Gocanto\SimplePDF\Builder;
use Gocanto\SimplePDF\TemplateContext;

Route::get('custom-template', function (Builder $builder) {

    $context = TemplateContext::make([
        'title' => 'foo',
        'name' => 'bar',
        'content' => '<h1>Some amazing content!</h1>',
    ]);

    $builder->addLocation(resource_path('views/home'));
    $new = $builder->withTemplate('home');
    $new->make($context);

    return $new->render();
});

As you can see, the first three steps are the same as the default implementation, so there is no need to explain further on this regard. Now, we need to clarify the differences on its setup.

  • First of all, we tell the builder about our templates root folder by invoking the addLocation method. This way, we will be able to have a views root folder to keep our different templates.

  • Second of all, we will register the custom templates by calling the withTemplate method. Please, do bear in account this is an immutable method, therefore, we will have a new Builder instance as result.

  • Lastly, we will call the make and render method in the same way we did with the default template above.

Features

  • Multi templates ability.
  • The state is immutable, meaning all the withers as withStream, withTemplate and withHeaders methods will return a new instance of the Builder.
  • The exported stream is expose for custom manipulations, meaning you can pass a call back to the render method to manipulate the given stream before rendering time. Like so:
    
    use Psr\Http\Message\StreamInterface;

$new->render(function (StreamInterface $stream) { //do something amazing with the stream echo $stream->getContents(); });



## TO DO

- [ ] (Gus) Allow rendered HTML or Blades files template as part of the `TemplateContext` content field.
- [ ] (interested?) Allow more engines like twig.
- [ ] (interested?) Make it framework agnostic.
