@Nurguly Ashyrov Hi, is there a way to add images/files to a page with the updatePage method ? If not, do you plan to implement it or do I have to do this another way ?

Thanks again :)

Unfortunately not yet. I am planning to implement them. But I am a bit busy now and it would definitely take some time to implement it. For now, you will have to do it some other way. Sorry :(

When I go to GraphiQl interface, selector argument for template fields does not appear to be optional as it's in the screencast. However, if I provide a selector, it works as expected. Do I need to set up something on backend?

How it looks on my GraphiQL:

How it is in the screencast

Hi @abdus. You are good to go actually. The argument is required only when there is an exclamation mark after it. It does not have to be = false. Sorry for the confusion, the way I explain it in screencast is a bit misleading. To sum it up, if there is an exclamation mark "!" at the end, it means it is required, of not then it is optional. The = false part means, the default value is false. I know, it sounds stupid. It was a bug in the library I used for this module. I updated it to the latest version since the screencast and now it shows correctly. The = false part is actually is a bug in older version of the module. You probably installed the latest version which shows correctly.

So, your version is actually is the way it supposed to be. The version in the screencast is a bit misleading, but still correct.

Thanks for the clarification. The problem is that if I dont specify any selector, I get empty array, also an error

chrome_2017-04-06_15-50-19.thumb.png.00e9aa75f76ebead5470e0a37f80b24b.png

But if I specify a selector, it all works fine

I'm not sure if this is the expected behavior.

Well now I am embarrassed. :( So sorry. It turns out upgrading to the latest graphql library broke some stuff. For some reason I did not check the queries without the selectors. I made some fixes. This should solve your problem. Please get the latest version and try again.

Thanks a lot for the changes, it works without a problem now :)

Also, is it possible for you to add some hookable functions to the module so that we can add custom queries and mutations? Inside Schema::build(), query and mutation fields are defined, maybe split build() method into ___getMutations and ___getQueries, then we can modify $event->returns inside hooks to add our own fields? Something like this maybe:

<?php
// maybe build parameters in 
// /ProcessGraphQL/ProcessGraphQL.module

public function ___getQueries() {
  // build an assc. array of FieldInterface objects
  return [...];
}

public function ___getMutations() {
  // build an assc. array of FieldInterface objects
  return [...];
}

public function executeGraphQL()
{
  // instantiating Processor and setting the schema

  $schema = new Schema($this->___getQueries(), $this->___getMutations());
  $processor = new Processor($schema);

  // ...
}

then inside Schema.php you would just use the provided fields.

<?php
class Schema extends AbstractSchema {
    private $queries = [];
    private $mutations = [];

    public function __construct($queries, $mutations)
    {
        // populate fields, perform checks etc
    }

    public function build(SchemaConfig $config)
    {
        $moduleConfig = Utils::moduleconfig();
        $query = $config->getQuery();
        $mutation = $config->getMutation();

        // add other query fields
        $query->addFields($this->queries);
        $mutation->addFields($this->mutations);
    }
}

It's a proof of concept, needs better separation of concerns etc, but it should work, why wouldn't it.

Or maybe use $moduleConfig instead of causing fragmentation.

<?php // Schema.php
public function build(SchemaConfig $config)
{
	// $moduleConfig is an instance of ProcessGraphQL module
	$moduleConfig = Utils::moduleconfig();
	$customQueries = $moduleConfig->___getQueries();
	$customMutations = $moduleConfig->___getMutations();

	$query = $config->getQuery();
	$mutation = $config->getMutation();

	$query->addFields($customQueries);
	$mutation->addFields($customQueries);
	// then populate your own fields etc.
}

Done! :)

The latest version now allows you to hook into getQuery & getMutation methods of the ProcessGraphQL class. Those hooks are solely there so you could modify the query and mutation operations. Here how it might look like in your template file.

<?php namespace ProcessWire;
use Youshido\GraphQL\Type\Scalar\StringType;

$processGraphQL = $modules->get('ProcessGraphQL');

wire()->addHookAfter('ProcessGraphQL::getQuery', function ($event) {
    $query = $event->return;
  
    $query->addField('hello', [
        'type' => new StringType(),
        'resolve' => function () {
            return 'world!';
        }
    ]);
});

echo $processGraphQL->executeGraphQL();

The above code will add a hello field into your GraphQL query that responds with the string "world!". You'll have to use the Youshido\GraphQL library that ProcessGraphQL module uses internally. The same thing could be done with the mutation operation via getMutation  hook method.

@Nurguly Ashyrov I am trying to build a mutation field for mailing list subscription that takes in email address and returns status code and error messages, if any. 

<?php namespace ProcessWire;
// /site/templates/graphql.php

use ProcessWire\Api\SubscriptionField;
require_once '../modules/ProcessGraphQL/vendor/autoload.php';

$processGraphQL = modules()->get('ProcessGraphQL');

wire()->addHookAfter('ProcessGraphQL::getMutation', function ($event) {
    $query = $event->return;
    $query->addField(new SubscriptionField());
});

echo $processGraphQL->executeGraphQL();

Here's my SubscriptionField definition

Spoiler

<?php namespace Processwire\Api;
// /site/templates/api/SubscriptionField.php

use Youshido\GraphQL\Config\Field\FieldConfig;
// others

class SubscriptionField extends AbstractField
{
    public function getType()
    {
        return new SubscriptionType();
    }

    public function resolve($value, array $args, ResolveInfo $info)
    {
        return [
            'statusCode' => 200,
            'errors' => [
                'no error'
            ]
        ];
    }

    public function build(FieldConfig $config)
    {
        $config->addArgument('email', new NonNullType(new StringType()));
    }
}

and my SubscriptionType class

Spoiler

<?php namespace ProcessWire\Api;
// /site/templates/api/SubscriptionType.php
use Youshido\GraphQL\Type\ListType\ListType;
// others

class SubscriptionType extends AbstractObjectType
{

    public function getName()
    {
        return 'Subscription';
    }

    public function build($config)
    {
        $config->addField('statusCode', [
            'type' => new NonNullType(new IntType()),
            'description' => 'The subscription status code. E.g. 200 if successful.',
            'resolve' => function ($value) {
                return (integer)$value->statusCode;
            }
        ]);

        $config->addField('errors', [
            'type' => new ListType(new StringType()),
            'description' => 'Human readable subscription errors. E.g. "Added to list!"',
            'resolve' => function ($value) {
                return (string)$value->errors;
            }
        ]);
    }

}

When I open the GraphiQL console, I get this error

chrome_2017-04-09_17-44-58.png.e7445fbe2fd0a032a0fcf2d9444d5ce0.png

I am not sure why PHP can't find the class, any ideas?

When I manually require field class (require_once 'api/SubscriptionField.php';), it resolves the class, but then cannot resolve others (error: Class 'Youshido\GraphQL\Field\AbstractField' not found)

@abdus First of all you don't need to import ProcesGraphQL's vendor.php file. It is done automatically when you do 

$processGraphQL = modules()->get('ProcessGraphQL');

Second is, I don't see where you include your /site/templates/api/SubscriptionField.php file into graphql.php. So replace the 

require_once '../modules/ProcessGraphQL/vendor/autoload.php';

with

require_once "./api/SubscriptionType.php";

in your graphql.php and it should work.

Also, your SubscriptionField class requires the public function getName().

Thanks for the guidance @Nurguly Ashyrov. The problem was that I wasn't including calling the module (and therefore not autoloading GraphQL classes) before I included mine. That was why it wasn't resolving.

<?php
// CORRECT
$processGraphQL = modules()->get('ProcessGraphQL');
require_once 'api/SubscriptionField.php';
require_once 'api/SubscriptionType.php';

// INCORRECT
require_once 'api/SubscriptionField.php';
require_once 'api/SubscriptionType.php';
$processGraphQL = modules()->get('ProcessGraphQL');

For reference here's a simple mutation field implementation

<?php
wire()->addHookAfter('ProcessGraphQL::getMutation', function ($event) {
    $query = $event->return;
    $query->addField('log', [
      	// define return object under type
        'type' => new ObjectType([
            'name' => 'Log',
            'fields' => [
                'result' => [
                    'type' => new StringType()
                ]
            ]
        ]),
      	// available arguments for the query
        'args' => [
            'text' => new StringType()
        ],
      	// what to do with the request
        'resolve' => function ($value, $args) {
            // process given input
          	// return object outline should be same as 'type'
            return [
                'result' => 'done. ' . $args['text']
            ];
        }
    ]);
});

When you refresh GraphiQL console, you get your new field!

Hi,

I just tried the module and get a JSON.parse Error because the query responded  this error:.

EDIT: Running on PHP 7.1 on Heroku and ext-mbstring was missing. I installed it and the error is away :-)

hi @Nurguly Ashyrov, I am planning to use this module to share content from one site to another. I got it up and running on my staging server but I would like to restrict access to the API data. How would you set up authentication to consume GraphQL data remotely?

Thx
Rudy

I Just played around with it a little. Looks awesome so far! It would be great if PageTable was supported, or is it already possible with a workaround?

Hey, Rudy! I couldn't fully understand your use case. I guess you want to restrict access to certain entities, like your other site. It is very easy to restrict access to certain ip address. Just before serving GraphQL API you could check for the requested entities ip address and behave accordingly. For example:

<?php
if ($_SERVER['REMOTE_ADDR'] == 123.234.34.1 ) {
  echo $modules->get('ProcessGraphQL')->executeGraphQL();
} else {
  echo 'Access Denied';
}

I can't say for sure if that's what you are asking though. If not, please give more details on what you are trying to achieve.

@Nurguly Ashyrov,

Your solution is actually quite simple and should work in my current case. A proper authentication (oAuth or JWT or even a simple token exchange) would be ideal.

My current use case: I have a master PW website with all the content. I also have 5 other websites that draw content from the master site. Essentially I want to treat the master site as an API server, serving data via GraphQL.

Thx
Rudy

PageTable is not supported yet. To be honest I am very busy right now and don't have much time to update this module. So I can't say when additional features will be added. Until then, you'll have to figure out your own way. Sorry :)

Hi @Nurguly Ashyrov, this looks like a great module - thank you for developing it!

I'm a complete noob to the world of GraphQL, and have been trying for two days to get this module running in combination with Ember.js. If I could get it to work, it sure would be a glorious combination. But so far it has been pretty frustrating :o

One thing that I keep running into, is that your implementation always returns an array of pages, using the 'list' field* inside the query.
However, this makes it impossible to request a single page. Even when using something like limit=1 in the selector. 

For instance, I could imagine this to work fine

{
  basic_page(s: "name:contact") {
    first {
      id
      name
    }
  }
}

Which then could return 

{
    "data": {
        "basic_page": {
            "first": {
                "id": "1017",
                "name": "contact"
            }
        }
    }
}

Basically, any of PW's regular PageArray methods to find something would be a welcome addition ( ie. ->eq(n), ->get(selector), ->first(), ->last(), etc.)

Is this something I can achieve with the getQuery hook? Or in another way?
Thanks in advance for any pointers or help. 

(* I have to say, this use of the field keyword is very confusing for a long time PW user).

Hey everyone!

It's been a while since I last had a time to work on this module. But now I finally managed to focus on this module. So here are the latest updates.

The codebase of the module grew very big and the more features I added the more time I had to spend to make sure the changes I made does not break anything. Because I had to manually verify if everything works as expected. After long night hours of trial and error I managed to setup tests for this module. Tests will help us quickly add/remove features as needed, because now there is no need for manually verifying all edge cases. Also I setup the Travis-CI so people can contribute more confidently and I can merge pull requests without worrying! There are already bunch of tests, but there is still some I'll be adding.

🎉 ProcessGraphQL.svg?branch=master 🎉

I will add some documentation on how to run tests locally in github wiki pages soon and let you know here.

Another thing to note is that the master branch of our module no longer tracks the vendor code. This means that if you download the master branch and put it into your /site/modules directory it will not work. Instead you should use release builds that are a cleaned version of the module. It includes required vendor codes and does not have extra files that are not relevant to ProcessWire. Like presentation gif images, test files and so on. This makes the module size smaller!

Hey @eelkenet!
That seems reasonable to me. I was planning to add those fields. Didn't have time till now. I'll let you know as soon as I implement them.

You won't be able to add those fields via getQuery hook btw. The getQuery hook is there for very trivial custom fields to be honest. Like your api version number, or your contact data or anything you want to send via GraphQL api without creating templates, fields and pages for it.

More updates!

Here is what was added since my last post:

  • FieldtypeDatetime now supports format argument. Which allows you to pass PHP date format string and retrieve your datetime values formatted the way you want. Besides FieldtypeDatetime fields, the built-in fields created and modified are also support new format argument.
  • FieldtypeOptions is now supported.
  • first and last fields on PageArray types are now supported. As per @eelkenet's request. See above post for details on those.
  • Finally, now there is a way to add support for any fieldtype you want via third-party module. What you need to do is create a module with the name exactly as the fieldtype you want to add support for with "GraphQL" prefix. So for FieldtypeMapMarker it would be GraphQLFieldtypeMapMarker. Then you need to add three required methods and install it. This will automatically add GraphQL support for your desired fieldtype and it will be available in your GraphQL api. Checkout the documentation and an example module for reference.

It is the successor of "RockDataTables" and requires RockFinder to get the data for the grid easily and efficiently. It uses the open source part of agGrid for grid rendering.
       
      WHY?
      ProcessWire is awesome for creating all kinds of custom backend applications, but where it is not so awesome in my opinion is when it comes to listing this data. Of course we have the built in page lister and we have ListerPro, but none of that solutions is capable of properly displaying large amounts of data, for example lists of revenues, aggregations, quick and easy sorts by the user, instant filter and those kind of features. RockGrid to the rescue 😉 
       
      Features/Highlights:
      100k+ rows Instant (client side) filter, search, sort (different sort based on data type, eg "lower/greater than" for numbers, "contains" for strings) extendable via plugins (available plugins at the moment: fullscreen, csv export, reload, batch-processing of data, column sum/statistics, row selection) all the agGrid features (cell renderers, cell styling, pagination, column grouping etc) vanilla javascript, backend and frontend support (though not all plugins are working on the frontend yet and I don't plan to support it as long as I don't need it myself)  
      Limitations:
      While there is an option to retrieve data via AJAX the actual processing of the grid (displaying, filtering, sorting) is done on the client side, meaning that you can get into troubles when handling really large datasets of several thousands of rows. agGrid should be one of the most performant grid options in the world (see the official example page with a 100k row example) and does a lot to prevent problems (such as virtual row rendering), but you should always have this limitation in mind as this is a major difference to the available lister options that do not have this limitation.
      Currently it only supports AdminThemeUikit and I don't plan to support any other admin theme.

      Support: Please note that this module might not be as easy and plug&play as many other modules. It needs a good understanding of agGrid (and JavaScript in general) and it likely needs some looks into the code to get all the options. Please understand that I can not provide free support for every request here in the forum. I try to answer all questions that might also help others or that might improve the module but for individual requests I offer paid support for 60€ per hour.
       
      Changelog
      180711 bugfix (naming issue) 180630 alpha realease  
      Use Cases / Examples:
      Colored grid cells, Icons, Links etc. The Grid also has a "batcher" feature built in that helps communicating with the server via AJAX and managing resource intensive tasks in batches:

      Filters, PW panel links and instant reload on panel close:

      You can combine the grid with a chart library like I did with the (outdated) RockDataTables module:

      Update 2018-07-09: ProcessNetteTester module is available in the Modules Directory and on GitHub.

      This is a short tutorial on how to use Nette Tester with ProcessWire.
      As you will see it's very easy to setup and use and it's perfect for testing your code's functionality. With bootstrapping ProcessWire it's also possible to check the rendered markup of pages using the API, checking page properties, etc. It's also a great tool for module developers for writing better code. 
      While there will be nothing extraordinary here that you couldn't find in Tester's docs this can serve as a good starting point.
      Prerequisites: PHP 5.6+
      01 Download Tester
      Go to https://github.com/nette/tester/releases and download the latest release (currently 2.0.2). Download from the link reading "Source code (zip)". You can use composer also if you wish.
      02 Extract Tester files
      Create a new directory in your site root called "tester". Extract the zip downloaded here, so it should look like this:
      /site /tester/src /tester/tools /tester/appveyor.yml /tester/composer.json /tester/contributing.md /tester/license.md /tester/readme.md /wire ... 03 Create directory for test files
      Add a new directory in "/tester" called "tests". Tester recognizes "*.Test.php" and "*.phpt" files in the tests directory, recursively. 
      04 Create your first test
      In the "tests" directory create a new "MyTest.php" file.
      The first test is a very simple one that bootstraps ProcessWire and checks if the Home page name is "Home". This is not the smartest test but will show you the basics.
      Add this to "/tester/tests/MyTest.php":
      <?php namespace ProcessWire; use \Tester\Assert; use \Tester\DomQuery; use \Tester\TestCase; use \Tester\Environment; require __DIR__ . '/../src/bootstrap.php'; // load Tester require __DIR__ . '/../../index.php'; // bootstrap ProcessWire Environment::setup(); class MyTest extends TestCase {     // first test (step 04)     public function testHomeTitle()     {         $expected = 'Home'; // we expect the page title to be "Home"         $actual = wire('pages')->get(1)->title; // check what's the actual title Assert::equal($expected, $actual); // check whether they are equal     }     // second test will go here (step 06)     // third test will go here (step 07) } // run testing methods (new MyTest())->run(); I've added comment placeholders for the second and third tests that we will insert later.
      05 Run Tester
      Tester can be run either from the command line or from the browser. The command line output is more verbose and colored while in the browser it's plain text only (see later).
      Running from the command line
      Navigate to the "/tester" directory in your console and execute this:
      php src/tester.php -C tests This will start "/tester/src/tester.php" and runs test files from the "/tester/tests" directory. The "-C" switch tells Tester to use the system-wide php ini file, that is required here because when bootstrapping ProcessWire you may run into errors (no php.ini file is used by default). You may load another ini file with the "-c <path>" (check the docs).
      If the title of your Home page is "Home" you should see this:

      If it's for example "Cats and Dogs", you should see this:

      Running from the browser
      First we need to create a new PHP file in ProcessWire's root, let's call it "testrunner.php". This is because ProcessWire doesn't allow to run PHP files from its "site" directory.
      The following code runs two test classes and produces a legible output. IRL you should probably iterate through directories to get test files (eg. with glob()), and of course it's better not allow tests go out to production.
      <?php ini_set('html_errors', false); header('Content-type: text/plain'); echo 'Starting tests.' . PHP_EOL; echo '--------------------------' . PHP_EOL; $file = __DIR__ . '/PATH_TO/FirstTest.php'; echo basename($file) . ' '; require $file; echo '[OK]' . PHP_EOL; $file = __DIR__ . '/PATH_TO/SecondTest.php'; echo basename($file) . ' '; require $file; echo '[OK]' . PHP_EOL; echo '--------------------------' . PHP_EOL; echo 'Tests finished.'; exit; Navigate to "DOMAIN/testrunner.php" in your browser to execute the file. If every test succeeds you should get this:

      If there are failed tests the execution stops and you can read the error message. If there were more tests (eg. ThirdTest), those won't be displayed under the failed test.

      06 DOM test
      This test will check if a page with "basic-page" template has a "h1" element. We will create the page on the fly with ProcessWire's API. To keep things simple we will add the new test as a new method to our MyTest class.
      Add this block to the MyTest class:
      public function testBasicPageHeadline() {     $p = new Page();     $p->template = 'basic-page';     $html = $p->render();     $dom = DomQuery::fromHtml($html);     Assert::true($dom->has('h1')); } This will most likely be true but of course you can check for something more specific, for example "div#main". Note that we have used the DomQuery helper here (check the "use" statement on the top of the file).
      07 Custom function test
      You will probably want to make sure your custom functions/methods will work as they should so let's write a test that demonstrates this.
      I don't want to complicate things so I'll check if the built-in "pageName" sanitizer works as expected. Add this to the myTest class:
      public function testPageNameSanitizer() {     $expected = 'hello-world';     $actual = wire('sanitizer')->pageName('Hello world!', true);     Assert::equal($expected, $actual); } This should also be true. Try to change the expected value if you are eager to see a failure message.
       
      08 Next steps
      You can add more methods to the MyTest class or create new files in the "tests" directory. Check out the range of available Assertions and other features in the docs and see how they could help you writing more fail-safe code.
      Once you make a habit of writing tests you'll see how it can assist making your code more bulletproof and stable. Remember: test early, test often 🙂
      If you find out something useful or cool with Tester make sure to share.
