Hello friends Tony here welcome so in
this video I'm going to explain you the
folder structure on laravel and here we
have the larel project we have some
folders and files and let's start with
the app directory so the app directory
is where the logic of our app is and
here we have the STP models and
providers
subdirectory so inside the HTP folder we
Define the controller we using them for
the logic with the STP request and then
we have models now each database table
has a corresponding model which is used
to interact with that table and models
allow you to query for data in your
tables as well as insert new records in
uh the table then we have a providers
and in L level we have only one
provider on previous version since we
had more than that so here we can
register any application services and
boost up any application Services okay
let's start with second one which is the
bootstrap directory so the bootstrap
directory inel is crucial for the
application startup process also known
as bopping and it contains several key
elements for setting up the larel here
we have the app PHP file this file in
larel 11 acts as the central piece for
bootstrapping the LEL the global
configuration file it loads the
framework and configures auto loading
for your projects
classes we have also the providers here
we're going to register all the
providers okay now let's start with the
config directory and also we have some
files here uh in the previous V versions
also here we had more than what we have
right now with the L 11 we have more
clean uh project so the config directory
in larel is the central location for all
your uh applications configuration files
and this files define various settings
that control how your application
operates some of the common things you
can configure included database
connection as you can see here uh mail
server uh quiz Services session and so
on okay then we have the database
directory so the database directory
stores files related to managing your
applications database and also we have
the database SQL light here as you can
see we have factories so this are
classes that help you generate realistic
test data for your database tables and
this is useful for seeding your database
with simple data for testing then we
have migrations migration these are the
files that Define the structure of your
data datase tables and lel's migration
system allow you to create and modify
tables over time in a controlled way and
we are going to learn them more at the
course let's close then we have this
seders directory so this are files that
contain this are files that contain code
to populate your database with test data
using the factories mentioned
earlier all okay then we have the public
directory so in larav the public
directory is a crucial folder for
storing files that need to be accessible
by users through the web browser so it
acts as the document route of your
application and what we can store here
we can static assets like images CSS
JavaScript and fonts and also as you can
see contains the this index. PHP file
the entry point for your larel
application so this is the entry point
index inside the public directory okay
then we have the Resources directory and
in LEL this directory is a location for
storing various application resources
that are not meant to be directly
accessed on the web so the opposite of
the public directory is the Resources
directory so it acts as a stage in area
for assets and view templates before
they are published or compiled and here
for example we have
CSS uh JS
files and also the views and this
directory stores blade template files
that Define the structure and layout of
your
application and lar templates engine
this blade. blade. PHP compiles this
files into standard HTML pages that are
served to the
browser okay next let's see the route
directory so the route directory in
larel is where you defined all the
routes for your application and this
routes map URLs the specific controller
action that handled in Comming requests
and L automatically loads the routes
files you defined in here by default the
L comes with these two files the console
and the web we are going to work with
web
mostly so this file defines routes for
you your web interface and this routes
typically benefit from features like a
session State csrf protection and cookie
encryption which are provided by the web
middleware group in larel okay then we
have this console here we're going to
register the Artisan commands Sher and
so
on next we have the storage directory
the storage directory in is a central
location for storing various files used
by the framework and your application we
have the app subdirectory this
subdirectory can store any files your
application generates uploaded user
avatars and so on then we have the
framework this subdirectory stores files
created by larav itself such as compiled
blade templates file based session Etc
then we have
logs these subdirectory store log files
containing information about your
application's activity okay then we have
the test directory and the test
directory in L is dedicated to writing
automatic test for your application and
we have the feature and unit
subdirectories here so let's start with
the features this subdirectory houses
feature test and this test simulate user
interactions with your application often
involving multiple components working
together then we have the unit
subdirectory this subdirectory stores
unit test this test focus on isolated
units of your code typically a single
class or a method and they aim to verify
the correctness of individual
functionalities okay then we have the
vendor directory and the vendor
directory in laravel manages
dependencies for your project it houses
all the third- party libraries and
packages that your project relies on the
function this includes the core drial
framework itself along with any
additional packages you've installed
using composer
dependency management tool and here we
have
laravel itself as you can
see okay and then we have some files
here but what I'm going to show you in
this video is this EnV file now the EnV
file in darav is a special configuration
file that stores critical information
for your application it's essentially a
text file with key value pairs as you
can see
where the key acts as a name for the
variable and the value is the actual
data and that's it all about this video
what I wanted to show you I hope you
enjoy friends and if you like such a
