Flask is the perfect web application development tool for web developers because it’s easy to use, supports custom development environments and provides robust, robust error handling. 

For this post, we’re going to explore the benefits of using Flask to develop your next web application. 

In the spirit of open source, we’ll be using the Flask-server project as our reference for all of this. 

The Flask-Server project provides a lightweight web server that can be used to manage your Flask application.

It’s not the easiest to set up, but once you’re up and running, you can get started quickly. 

This article will walk through setting up a basic Flask project using the Flask-server.py project.

If you’re new to Flask and are new to the Flask development community, check out our Flask documentation. 

Flask-Server is available as an Open Source Project on GitHub. 

Install Flask on Ubuntu and Linux The first thing we’ll need to do is install Flask on our Ubuntu, Linux and Mac systems. 

Ubuntu is a popular operating system and has a number of popular Linux distributions. 

To install Flask, run the following command in your terminal: sudo apt-get install python-flask python-pip pip install flask-server pip install werkzeug Flask-Sqlite3.0.0 pip install git1.5.2 python-pyasn1-dev Install Flask-Client on Ubuntu Next, we need to install Flask-client on our system. 

Follow the steps below to install and configure Flask-Cli on your Ubuntu system.

Install Flask on your Mac Next we need a directory to install Flask on your system.

Create a new folder called client in your Home directory.

Navigate to the directory you created in step 3.

Find and execute the following script to install the client.

sudo mkdir client sudo cp client_0.py client.py sudo chmod a+x client_1.py Install Flask and Flask Client on your Windows or Mac Now we need some way to manage our Flask-based applications.

We’ll use the Flask client to manage the Flask app.

In the following steps, we are going to assume you are running Windows or macOS on a Linux system.

Navigate to: C:\Program Files (x86)\Flask on Windows and macOS.

Open a command prompt on your computer and run the Flask command prompt. 

Press Enter to continue. 

Next navigate to: C:\ProgramData\Flask.

Click on the Start menu icon in the top left corner of your screen. 

Select Run as Administrator. 

Type the following commands to install a virtual machine and install the Flasheeds Python Client.

sudo pip install virtualenv virtualenv-bin virtualenv pip install Flask pip install nginx python-fuse pip install sqlite3 python-cli python-sqlite3-dev  Now, we will be installing Flask and Flask Client in our virtual environment. 

Navigate back to the virtual environment and install Flask.

On the command line, type: virtualenv virtualenvs1.virtualenvs.com: pip install Virtualenvwrapper Next run the command: python virtualenvwrapper.py install_virtualenv_client_server_0_0  To verify the installation has completed, type the following in the terminal: pip install -r requirements.txt  If you get an error message stating the virtualenv failed to install, then you need to create a virtualenv again. 

If this doesn’t happen, you may need to use the following configuration command to create your own virtualenv:  pip install python virtualenv.yml  Next start up your local server and navigate to the server.py file. 

On the virtual command line:  python server.pl Start the Flask server and ensure the Flask application is running. 

After Flask is up and functional, you should see the following output:  Flachs client.

Flask application listening on localhost:8000, listening on 127.0, listening in 127.127.0:8000. 

Welcome, Flask client. 

Congratulations!

You’re now ready to use Flask as a web development tool. 

Use Flask as the Database Engine for Your Application To learn more about Flask, you’ll need a database. 

You can use a database in the following ways. 

Create a SQLite database.

Create a database that supports MongoDB.

Create an SQLite Database with MongoDB, Mongoose and Mongoose+Flask Create a MongoDB Database with Flask, MongoDB+Flase, Mongooserver, MongoOS, Mongoite, MongoExpress and MongoDBServer. 

Creating a database is easy with a single
