An AirBnB clone.
HolbertonBnB is a complete RESTful web application, integrating file and database (MySQL) storage in a back-end API with front-end interfacing in a clone of AirBnB. The front-end is designed using HTML5/CSS3 and is served using Python Flask. The application is configured on a distributed system - two web servers and one load balancer - with Nginx and HAProxy.
HolbertonBnB is still in active development, with complete functionality set to deploy in the coming month:
- Complete integration of a RESTful API
- Full configuration of website with domain name
- Serving of dynamic content using JavaScript
This web app has been the capstone project of my full-stack education at Holberton School and I want to show it off as a demonstration of all the skills I've learned at this school.
With that said, I must clarify that it is not complete. As mentioned, the clone is a work-in-progress, with full deployment as a RESTful API still to come. Finishing touches will be occurring over the next month, my final at Holberton.
Recognizing that I am sharing a near-complete project, I additionally put together a small Flask app according to the specifications described in the application. Please take a look at this separate repository here:
https://github.com/bdbaraban/lyft_apprenticeship_application
Nonetheless, allow me to talk a little more about this AirBnB clone. This repository is the second iteration of the project. In the first version (viewable here), I, together with a cohort mate, built up the initial file storage back-end and console from scratch. We pair programmed for most all of this version one work.
In this second iteration of the project, I, together with a new partner, inherited a different version of the same back-end written by a pair of Holberton students from an older cohort. We then pair programmed to build up the database storage engine of the back-end.
In between each version, I put together an entire CSS-styled HTML web page for the project. This front-end development was coded independently, although the HTML files I personally wrote are only posted in version one (the web_static folder in this directory was included in the fork). Addtionally, all Shell, Puppet, and Fabric deployment scripts/manifests were coded myself.
The README's in both repositories were almost exclusively written myself.
I hope this helps clear things up. I apologize for the confusing versioning, but the takeaway is that I've been directly involved in coding at least an implementation of everything in this repository. And hey, software development is no fun without some confusing version control, right? ๐ ๐ญ
Please let me know if you have any questions!
The front-end of HolbertonBnB was designed from scratch using HTML5/CSS3 pages integrated using Flask. While the front-end has not yet been officially deployed, screenshots are viewable in the README of the web_flask directory.
HolbertonBnB supports the following classes:
- BaseModel
- User
- State
- City
- Amenity
- Place
- Review
The above classes are handled by one of either two abstracted storage engines, depending on the call - FileStorage or DBStorage.
The default mode.
In FileStorage
mode, every time the backend is initialized, HolbertonBnB
instantiates an instance of FileStorage
called storage
. The storage
object is loaded/re-loaded from any class instances stored in the JSON file
file.json
. As class instances are created, updated, or deleted, the
storage
object is used to register corresponding changes in the file.json
.
Run by setting the environmental variables HBNB_TYPE_STORAGE=db
.
In DBStorage
mode, every time the backend is initialized, HolbertonBnB
instantiates an instance of DBStorage
called storage
. The storage
object
is loaded/re-loaded from the MySQL database specified in the environmental variable
HBNB_MYSQL_DB
, using the user HBNB_MYSQL_USER
, password HBNB_MYSQL_PWD
, and
host HBNB_MYSQL_HOST
. As class instances are created, updated, or deleted, the
storage
object is used to register changes in the corresponding MySQL database.
Connection and querying is achieved using SQLAlchemy.
Note that the databases specified for DBStorage
to connect to must already be
defined on the MySQL server. This repository includes scripts
setup_mysql_dev.sql and setup_mysql_test.sql
to set up hbnb_dev_db
and hbnb_test_db
databases in a MySQL server,
respectively.
The console is a command line interpreter that permits management of the backend
of HolbertonBnB. It can be used to handle and manipulate all classes utilized by
the application (achieved by calls on the storage
object defined above).
The HolbertonBnB console can be run both interactively and non-interactively.
To run the console in non-interactive mode, pipe any command(s) into an execution
of the file console.py
at the command line.
$ echo "help" | ./console.py
(hbnb)
Documented commands (type help <topic>):
========================================
EOF all count create destroy help quit show update
(hbnb)
$
Alternatively, to use the HolbertonBnB console in interactive mode, run the
file console.py
by itself:
$ ./console.py
Remember, the console can be run with storage
instantiated in either FileStorage
or DBStorage
mode. The above examples instantiate FileStorage
by default, but
DBStorage
can be instantiated like so:
$ HBNB_MYSQL_USER=hbnb_dev HBNB_MYSQL_PWD=hbnb_dev_pwd HBNB_MYSQL_HOST=localhost HBNB_MYSQL_DB=hbnb_dev_db HBNB_TYPE_STORAGE=db ./console.py
The console functions identically regardless of the storage
mode.
While running in interactive mode, the console displays a prompt for input:
$ ./console.py
(hbnb)
To quit the console, enter the command quit
, or input an EOF signal
(ctrl-D
).
$ ./console.py
(hbnb) quit
$
$ ./console.py
(hbnb) EOF
$
The HolbertonBnB console supports the following commands:
- Usage:
create <class> <param 1 name>=<param 1 value> <param 2 name>=<param 2 value> ...
Creates a new instance of a given class. The class' ID is printed and
the instance is saved to the file file.json
. When passing parameter key/value
pairs, any underscores contained in value strings are replaced by spaces.
