Magento 2 backup script for developer

Leave a Comment / Scripts / By / January 16, 2023 /

Magento 2 developer usually require taking backup of live environment and setup on local or creating staging environment. We need to take backup of Database, App folder and composer.json minimal. We can add media and other assets for full fledged setup. I created a simple script to create backup of these two folder after reading env.php file. It will decrease time to take backup. We just need to put these script at root and run it. It is very flexible and you can make changes to your requirement as well. I will keep updating it and will add new features.

<?php 
//create backup file
$envData = include('app/etc/env.php');

//taking database backup
echo "Taking database backup \n";
if(isset($envData['db'])){
    $mysqlDump = 'mysqldump --user='.$envData['db']['connection']['default']['username'].' --password='.$envData['db']['connection']['default']['password'].' --host='.$envData['db']['connection']['default']['host'] .' '.$envData['db']['connection']['default']['dbname'] .' > db.sql;'; 
    exec($mysqlDump);
}

//zipping files
echo "Zipping required files to setup environment \n";
exec('zip -r files.zip db.sql composer.json app/');

die('finished');
?>

Magento 2.x – Cannot process definition to array for type tinytext

Leave a Comment / Magento 2 bugs / By / May 26, 2021 /

I faced issue while setup:upgrade in magento 2 instance. I fixed this issue in three steps as below.

Step 1: I open this file : /vendor/magento/framework/Setup/Declaration/Schema/Db/DefinitionAggregator.php

Find this function and replace code:

   public function fromDefinition(array $data)
    {
        $type = $data['type'];
        if (!isset($this->definitionProcessors[$type])) {
            echo "<pre>"; print_r($data); exit();
            throw new \InvalidArgumentException(
                sprintf("Cannot process definition to array for type %s", $type)
            );
        }
        $definitionProcessor = $this->definitionProcessors[$type];
        return $definitionProcessor->fromDefinition($data);
    }

Step 2 : Run setup upgrade and you will find out column name and it’s details. Now login in to mysql console and replace invoiceNumber by column which we found in last step. You will get all table information.

SELECT table_name, column_name from information_schema.columns WHERE column_name LIKE '%invoiceNumber%';

Step 3: Now update that column using below command. Run again setup:upgrade

ALTER TABLE TableName MODIFY InvoiceNumber VARCHAR(250);

Font optimization an avoid invisible text

1 Comment / Magento 2 performace optimization / By / September 25, 2021 /

Every Magento 2 store needs fonts to display styled text. Like other static assets it use bandwidth. It affects performance, if do not download before text required it. I am adding few suggestions for font optimization and some resources links as well. I will keep updated information for font here

  1. Try to use google font (why? read this link)
  2. Use no more than two fonts and check their size as well.
  3. Load them on priority basis using preload and swap to avoid invisible text during font loading (check this link)
  4. Use proper caching for fonts (check this link)
  5. Use less variants of fonts
