Speed Up Your Laravel Website Super Fast- Codexashish

Ashish — Sun, 22 May 2022 07:20:58 +0000

Speed Up Your Laravel website Super Fast

Laravel is the best back-end framework of PHP, and lots of companies are choosing Laravel for their large and medium-sized projects. SEO is incredibly important for each website. there are some tips you'll follow to create your laravel app super fast. So let's Start:-

1. Use Caching in production:

Each time you boot your laravel app , your app determines the middleware, resoles aliases, resolves route groups, and identifies the controller action and parameter inputs for each single route entry. so you'll be able to think how bad it's for your app within the production.

You can bypass route processing by caching all routes running this so.:-

php artisan route:cache

What about configuration caching ?? to bypass parsing your .env and config files on every app boot you must run:-

php artisan config:cache

use config() to access .env variables , avoid using env()

you must not compile your views whenever, just use pre-compiled blade template views, to try and do that run this command.

php artisan view:cache

**To cache a manifest of all of your app's events and listeners

run :**

php artisan event:clear

_Recreate boostrap/cache/compiled.php _

php artisan optimize

Alert :

You need to clear the cache to reflect any new changes by using the commands:

php artisan cache:clear php artisan view:clear php artisan route:clear php artisan clear-compiled php artisan config:cache

2. Remove Dev dependencies from the composer

When you develop your project likely you may be using some Dev packages to trace queries or other development things, remove those packages that aren't required within the production.

So just run one command within the production and then.:

composer install --prefer-dist --no-dev -o

One will use all 3 systems in one application to serve files from multiple locations like in a very distributed atmosphere.

5. Artisan Console

Laravel has its own instruction interface referred to as a trained worker. Common uses of trained workers embrace business enterprise package assets, managing information migrations, seeding, and generating boilerplate code for brand spanking new controllers, models, and migrations. This feature frees the developer from making correct code skeletons. One will extend the practicality and capabilities of the trained worker by implementing new custom commands.

MVT( Model View Template) architecture contains the following layers:

Model: The model describes the database schema and data structures. All database work is handled by models in Django like creating tables, creating fields, etc.

View: The view layer is a user interface that handles what a user sees on the web. The view retrieves data from the appropriate models and after that, it executes the data and it passes data to the template.

Template: The template layer is the collection of HTML files from where we handle how to show data to the users received from the view. In this layer, we do the formatting of data and show it on the web.

Controller: Controller is the heart of the system which handles requests and responses, loading and setting up a database connection.

Q.3: What is the difference between Django and Flask?

Ans: The main difference between Django and Flask are given below:
Django:
Django built for large projects
