This plugin is aimed at developers but provides easy to use static content forms through reusing OctoberCMS form behavior and the ability to expose API for going headless.

You do not need to generate or build models, this plugin stores data in the database but it's designed in a way that doesn't require any database development.

This plugin requires https://github.com/alsofronie/eloquent-uuid library. Because of OctoberCMS not clear way to provide composer dependencies with marketplace plugins in some scenarios you might need to add alsofronie/eloquent-uuid directly to your composer.json after installing the plugin by typing in the project root:

$ composer require alsofronie/eloquent-uuid

Repository with the latest OctoberCMS and plugin with working example setup: https://github.com/mcharytoniuk/octobercms-headless-example

The setup process should take about ~5 minutes overall if you get some practice. ;) There are actually 4 steps in this list (one of them is optional), it's just illustrated by some examples.

1. You need to create backend forms that would allow static content editing. To do so you need to create a local plugin in your OctoberCMS installation by typing in your project root:

$ php artisan create:plugin Acme.ContentEditor

Where Acme is your desired name. You can read more here: https://octobercms.com/docs/console/scaffolding#scaffold-create-plugin

2. Add backend form following this guide, but instead of using the default Backend.Behaviors.FormController behavior use Newride.Headless.Behaviors.StaticContentEditor behavior provided by Headless: https://octobercms.com/docs/backend/forms#introduction

Also, don't forget to create 'update.htm' or equivalent backend view to display the form.

Newride.Headless.Behaviors.StaticContentEditor extends the default FormController behavior. It uses form_config.yaml to generate static content API and component for you.

Inside your backend Controller you also can provide a public property with the page name your are going to edit (public $staticPageName). It will be used by static content component in your views and API routes. Your final controller should look somewhat like this:

<?php

namespace Acme\ContentEditor\Controllers;

use Backend\Classes\Controller;
use BackendMenu;

class Homepage extends Controller
{
    public $implement = [
        'Newride.Headless.Behaviors.StaticContentEditor',
    ];

    public $formConfig = 'config_form.yaml';

    // optionally you can provide static page name here
    // public $staticPageName = 'home';

    public function update(): void
    {
        parent::update();

        BackendMenu::setContext('Acme.ContentEditor', 'contenteditor', 'homepage');
    }

    // // optionally, you can implement such method to generate page name
    // // programatically in some way
    // public function staticContentGetPageName(): string
    // {
    //     return 'home';
    // }
}

In your config_form.yaml you can then configure your form fields while refering to those docs: https://octobercms.com/docs/backend/forms#form-fields

If should look like this:

name: My static content form
form: $/acme/contenteditor/controllers/homepage/fields.yaml

# You can skip 'modelClass' field. It is set by default to the model included
# in the plugin.
#   modelClass: Newride\Headless\Models\StaticContent

# You need to provide static page name either here or in the controller.
# The order of precedence this plugin uses to find the actual static page is:
# 1. `public $staticPageName` controller property
# 2. `public function staticPageName()` controller method
# 3. This config option.
static_page_name: home

3. In your Plugin.php file register backend navigation so you will be able to access your backend form. It should look somewhat like this:

<?php

public function registerNavigation(): array
{
    return [
        'contenteditor' => [
            'label' => 'Homepage Editor',
            'url' => Backend::url('acme/contenteditor/homepage/update'),
            'icon' => 'icon-align-left',
            'permissions' => ['acme.contenteditor.*'],
            'order' => 500,
        ],
    ];
}

If you have more editors you can nest them in side menu like this:

<?php

public function registerNavigation(): array
{
    return [
        'contenteditor' => [
            'label' => 'ContentEditor',
            'url' => Backend::url('acme/contenteditor/home/update'),
            'icon' => 'icon-align-left',
            'permissions' => ['acme.contenteditor.*'],
            'order' => 500,
            'sideMenu' => [
                'homepage' => [
                    'label' => 'Homepage',
                    'icon' => 'icon-home',
                    'url' => Backend::url('acme/contenteditor/homepage/update'),
                ],
                'team' => [
                    'label' => 'Team',
                    'icon' => 'icon-users',
                    'url' => Backend::url('acme/contenteditor/team/update'),
                ],
            ],
        ],
    ];
}

4. (optional) You can also expose headless API by adding this to your Plugin@boot method:

<?php

use Newride\Headless\Helpers\StaticContent;

class Plugin extends PluginBase
{
    // (...)

    public function boot()
    {
        StaticContent::expose('home');
    }

    // (...)
}

Your API will be accessible then under http://projecturl/api/v1/content/home. It will be linked to your form controller. You can expose as many static content endpoints as you need.

Response looks like this:

{
    "id": "<guid>",
    "created_at": "<date>",
    "updated_at": "<date>",
    "page_name": "home",
    "data": {
    }
}

That's all. :)

Headless uses your FormController's form config to generate API format. So for example if your /acme/contenteditor/controllers/homepage/fields.yaml from FormController looks like this:

fields:

    title:
        label: Homepage title
        required: true

    planet:
        label: World you are currently living in
        type: textarea
        size: small
        required: true

You can use it on your page like this:

title = "Home"
url = "/"
layout = "default"
is_hidden = 0

[staticContent static]
page_name = "home"
==

<p>Hello, {{ static.content.planet }}!</p> <!-- <p>Hello, World!</p> -->

Api response at http://projecturl/api/v1/content/home would look like this:

{
    "id": "<guid>",
    "created_at": "<date>",
    "updated_at": "<date>",
    "page_name": "home",
    "data": {
        "title": "Hello",
        "planet": "World"
    }
}

If you want an exception to be thrown when some CMS field is not set, you can use enableTwigStrictVariables CMS config option (in config/app.php file).

I hope this helps. If you need some help, feel free to fill an issue.
