LaraUpdater

self-update for your Laravel App

LaraUpdater allows your Laravel Application to auto-update itself !

When you release an application is most important maintain it, therefore, could be necessary to publish an update for bugs fixing as well as for new features implementation.

You deploy your App for several users:

• WITHOUT LaraUpdate

  Do you want to contact them one by one and send them the update using an email or a link ? ...mmm...very bad becouse each user (with admin role) have to overwrite manually all files on his deployment; or, you have to access manually all deployments (e.g. using FTP) and install for them the update.

• WITH LaraUpdater

  Let your application (ALONE) detects that a new update is available and notifies its presence to the administrator; furthermore, let your application install it and handles all related steps.

NEW VERSION change-log

Features:

> Self-Update

LaraUpdater allows your Laravel Application to self-update :) Let your application (ALONE) detects that a new update is available and notifies its presence to the administrator; furthermore, let your application install it and handles all related steps.

> Maintenance Mode

LaraUpdate activates the maintenance mode (using the native Laravel command) since the update starts until it finishes with success.

> Security

You can set which users (e.g. only the admin) can perform an update for the application; this parameter is stored in the config/laraupdater.php so each application can sets its users indipendently. Furthermore, LaraUpdater is compatible with Laravel-Auth.

> Fault tolerant

During the update LaraUpdate BACKUPS all files that are overwritten, so if an error occurs it can try to restore automatically the previous state. If the restoring fails, you can use the backup stored in the root of your system for a manual maintenance.

> Supports UPGRADE script

LaraUpdate can import a PHP script to perform custom actions (e.g. create a table in database after the update); the commands are performed in the last step of update.

Getting Started

These instructions will get you a copy of the project up and running on your server for development and testing purposes.

Prerequisites

LaraUpdater has been tested using Laravel 5.7 Recommended Laravel Version >= 5.x

Installing

This package can be installed through Composer:

composer require rohsyl/laraupdater

After installation you must perform these steps:

1) add the service provider in config/app.php file:

'providers' => [
    // ...
    rohsyl\laraupdater\LaraUpdaterServiceProvider::class,
];

2) publish LaraUpdater in your app

This step will copy the config file in the config folder of your Laraver App.

php artisan vendor:publish --provider="rohsyl\laraupdater\LaraUpdaterServiceProvider"

When it is published you can manage the configuration of LaraUpdater through the file in config/laraupdater.php, it contains:

    /*
    * Temp folder to store update before to install it.
    */
    'tmp_path' => '/../tmp',

    /*
    * URL where your updates are stored ( e.g. for a folder named 'updates', under http://site.com/yourapp ).
    */
    'update_baseurl' => 'http://site.com/yourapp/updates',

    /* ********************
     * POST INSTALL SCRIPT
     * ********************
     * If this file exists in your app after the extraction of the archive and if
     * it contains a laraupdater_post_upgrade($currentVersion, $lastVersion) method it will be executed.
     */
    'post_upgrade_file_location' => 'update/update.php',

    /*
     * The name of the file in which the last version information are stored on your webserver
     */
    'last_update_filename' => 'current.json',

    /**
     * The name of the file that contains the current version
     * This file is located at the root of the project
     */
    'current_filename' => 'version',

    /*
    * Set a middleware for every routes
    * Only 'auth' NOT works (manage security using 'permissions' configuration)
    */
    'middleware' => ['web', 'auth'],

    'permissions' => [
        /**
         * Set which policy to check permissions
         * You can create your own by implementing the
         * pcinaglia\laraupdater\Policies\ILaraUpdaterPolicy interface
         * and registering it here
         */
        'policy' => pcinaglia\laraupdater\Policies\AllowUserIdLaraUpdaterPolicy::class,
        'parameters' => [
            /*
             * This entry is related to the policy :
             * pcinaglia\laraupdater\Policies\AllowUserIdLaraUpdaterPolicy
             *
             * If you are not using this policy, you can remove it.
             *
             * Set which users can perform an update;
             * This parameter accepts: ARRAY(user_id) ,or FALSE => for example: [1]  OR  [1,3,0]  OR  false
             * Generally, ADMIN have user_id=1; set FALSE to disable this check (not recommended)
             */
            'allow_users_id' => [1],
        ]
    ],

3) Create version

To store current version of your application you have to create a text file named version and copy it in the main folder of your Laravel App. For example, create a file that contains only:

1.0.0

...use only 1 row, the first, of the file. When release an update this files is updated by LaraUpdate.

Create your update "repository"

1) Create the Archive

Create a .zip archive with all files that you want replace during the update (use the same structure of your application to organize the files in the archive).

1.1) Upgrade Script (optional)

You can create a PHP file named update/update.php to perform custom actions (e.g. create a new table in the database). This file must contain a function named laraupdater_post_upgrade($currentVersion, $newlyInstalledVersion) with a boolean return (to pass the status of its execution to LaraUpdater), see this example:

<?php

function laraupdater_post_upgrade($currentVersion, $newlyInstalledVersion) {

	command-1-to-connect-db
	command-2-to-create-table
	command-3-to-insert-data
	
	return true;
}
?>

Note that the above example does not handle any exceptions, so the status of its execution return always true (not recommended).

2) Set the Metadata for your Update:

Create a file named current.json like this:

{
	"version": "1.0.2",
	"archive": "RELEASE-1.02.zip",
	"description": "Minor bugs fix"
}

archive contains the name for the .zip Archive (see Step-1).

3) Upload your update

Upload current.json and .zip Archive in the same folder of your server (the one that will host the update).

4) Configure your application

Set the server that will host the update in config/laraupdater.php (see Installing):

For example, if you upload files under:

http://yoursites.com/updatesformyapp/RELEASE-1.02.zip
and http://yoursites.com/updatesformyapp/laraupdater.json

set 'update_baseurl' as follows: 'update_baseurl' => 'http://yoursites.com/updatesformyapp',

Usage

LaraUpdater implements three main methods that you can call using the routes:

updater.check

Returns '' (an update not exist) OR $version (e.g. 1.0.2, if an update exist).

updater.currentVersion

Returns the current version of your App (from version.txt).

updater.update

It downloads and installs the last update available. This route is protected using the information under 'allow_users_id' in config/laraupdater.php

I suggest, to not use directly these routes BUT to show an Alert when an update is available; the Alert could be contain a Button to perform the update, see the solution below:

(Example) Bootstrap 4 and JQuery solution

Add to view/layout/app.blade.php this HTML code (I suggest immediately before of @yield('content')):

<div id="update_notification" style="display:none;" class="alert alert-info">
	<button type="button" style="margin-left: 20px" class="close" data-dismiss="alert" aria-label="Close">
		<span aria-hidden="true">&times;</span>
	</button>
</div>            

, now add (at the end of view/layout/app.blade.php) this JQuery script:

<script>
    $(document).ready(function() {  
        $.ajax({
            type: 'GET',   
            url: 'updater.check',
            async: false,
            success: function(response) {
                if(response != ''){
                    $('#update_notification').append('<strong>Update Available <span class="badge badge-pill badge-info">v. '+response+'</span></strong><a role="button" href="updater.update" class="btn btn-sm btn-info pull-right">Update Now</a>');
                    $('#update_notification').show();
                }
            }
        });
    });
</script>

<< END >> ...to test it: publish an update and refresh the page to show the alert :-)
