public function import_data(Request $request)
{
    $success = true;

    try {

            ];

            $record_id = $item->id ?? null;
            $inserted_record = RecordModel::updateOrCreate(['id' => $record_id], $record_payload);

            if (!$inserted_record) {
                $success = false;
                break; // Stop further processing if any insert fails

Laravel Migration Error – SQLSTATE[HY000] [2002] php_network_getaddresses

by | May 15, 2023 | Laravel Blog Posts

SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo for mysql 
failed: Temporary failure in name resolution (SQL: select * from 
information_schema.tables where table_schema = laravel and 
table_name = migrations and table_type = 'BASE TABLE')

The issue has to do with the env variable DB_HOST
You need to change it. To what your localhost is configured for.
It can most likely be one of the following. 

mysql
127.0.0.1
localhost

or alternatively check your docker container name for your mysql DB:
mysql_container_name

php artisan ui bootstrap --auth
npm install 
npm run build

// With VUE
composer require laravel/ui --dev
php artisan ui vue --auth
npm install

Uploading your js build to the server

If you using git and working locally and using laravel vite.
Build your project and use the below gitignore. This will push your build to the server.

The below is that if you don't include certain directories then your build files will not get uploaded and some servers don't have suffucient resources to run builds online.
So you need to build locally and upload the build via GIT.

/vendor/
npm-debug.log
yarn-error.log
public/hot
public_html/storage
public_html/hot
public/robots.txt
storage/*.key
.env
.htaccess
Homestead.yaml
Homestead.json
/.vagrant
.phpunit.result.cache

Setup Node.js on Shared Hosting Apache Server (Cpanel)

by | Apr 25, 2023 | Apache Blog Posts, Hosting

First off you need access to the server terminal. Or SSH acces. If you have that then you can proceed. Else go get your Login permissions or SSH access.

Connect to your server using SSH or Cpanel terminal.

Run the following curl command to download the Node.js source code:bashCopy code

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

This will download the nvm (Node Version Manager) installation script and pipe it to the bash shell to run the script.

Once the installation is complete, run the following command to load nvm:bashCopy code

source ~/.bashrc

This will activate the nvm environment so you can install Node.js and npm.

Run the following command to install the latest version of Node.js

nvm install node

This will install the latest stable version of Node.js and npm.

Verify that Node.js and npm are installed correctly by running the following commands

node -v 
npm -v

These commands should output the versions of Node.js and npm installed on your server

Keep in mind that the above steps may not work on all shared hosting providers, and some providers may not allow you to install additional software on their servers. It's always a good idea to check with your hosting provider before attempting to install software on a shared hosting server.

Bootstrap Mobile Optimisation

by | Apr 16, 2023 | CSS Blog Posts

The best CSS library I have ever used for mobile Optimisation!

https://getbootstrap.com/

After full time developing since 2016 I still used this one almost every project I complete. In terms of mobile optimisation. Bootstrap remains king!

It is simple and easy to learn. Allowing new developers to pick it up fast. And cutting down the work load for mobile optimisation greatly. I highly recommend BootStrap to any web developer.
