Streamlit Tutorial For SEOs: How To Develop A UI For Your Python App

Posted by

Python is among the common programming languages for automating SEO processes.

One of the greatest libraries for developing a front-end for our apps with no HTML, CSS understanding, or coding with a JavaScript-powered framework is Streamlit bundle.

In this Streamlit tutorial, we will dive into how you can create a gorgeous app with Python and the Dockerfile for releasing your Streamlit app.

What Is Streamlit?

Streamlit is an open-source app framework (a Python package) that offers us the power for producing nice-looking apps with no front-end advancement knowledge.

This makes us devoid of participation in any front-end framework or coding in HTML, CSS, and JavaScript.

You use pure Python to develop your front-end.

When Will The Streamlit Library Become Useful?

To start with, if you are coding Python scripts that run regularly on a maker with a task scheduler like cron, Streamlit isn’t helpful for you.

But if you are establishing a tool that you wish to share with your employee, for instance, a keyword research app, you can use Streamlit.

Likewise, if you require a user authentication method, the Streamlit neighborhood established a package that can handle it for you.

Create A Streamlit App: Starting

Let’s create a simple app that gets autocomplete questions for a seed keyword from the Google public API.

Prior to beginning, create a folder on your device, and name it what you want.

Also, I will presume you have actually installed Python prior to and know the essentials of Python programs.

For the whole process, we require to use these Python libraries:

  • Requests.
  • Streamlit.
  • Streamlit-Authenticator.
  • PyYAML.

Likewise, we will import a Python basic library:

The tutorial code can be discovered in my Streamlit starter design template repository on Github.

Setting Up The Streamlit Plan

First off, I choose to develop a virtual environment by running python3 -m venv.env, and then setting up the Streamlit package by running pip3 install streamlit.

Now develop a Python script. Let’s call it streamlit_app. py.

In complicated projects that have a lot of functions, I choose to have separate Python script apply for my various functions and then import those into the streamlit_app. py or produce a separate app with Flask or FastAPI.

For example, in a keyword research app, I have a Python script for various functions that get data from Semrush, a script for getting the top 10 or 20 arise from Google, a script to get the Google autocomplete and Google-related searches, etc.

Get The Google Autocomplete Queries

For making requests, we need to use the Requests plan. To get this bundle, you require to run pip3 set up requests.

Also, to parse the autocomplete API action, we need to import the Python requirement JSON library.

To start with, we import the JSON standard library, the Requests plan for making demands, and Streamlit for producing our app.

Then, I specified a function for getting the Google autocomplete questions as a list of strings.

I used replace function two times to keep whatever easy, however you can use re library for utilizing regex.

“””A Streamlit app for getting the Google autocomplete inquiries “”” import json import requests import streamlit as st def google_autocomplete(keyword: str) -> list [str]: “””Get Google autocomplete inquiries for a seed keyword Args: keyword (str): The seed keyword Returns: list [str]: A list of the autocomplete inquiries “”” google_autocomplete_api: str=”https://www.google.com/complete/search” google_autocomplete_params: dict = reaction = requests.get(google_autocomplete_api, params=google_autocomplete_params) list_google_autocomplete_uncleaned: list [list] = json.loads((response.content). translate(“UTF-8”) [5:] [0] list_google_autocomplete_cleaned: list [str] = [aspect [0] replace(“, “). change(“, “) for element in list_google_autocomplete_uncleaned] return list_google_autocomplete_cleaned

The Streamlit App

Up previously, we have set up the Streamlit plan and defined our function to get the Google autocomplete questions. Now, let’s create the real app.

To see the Streamlit app, we require to run the Streamlit with the run streamlit_app. py command in the terminal for running our app in your area. After you run this command, by going to the http://localhost:8501/ URL, you can see the app.

Yes, it’s blank due to the fact that we didn’t include any heading, and so on, to it.

Add A Heading To The Streamlit App

Let’s add a heading to our app. As you see above, I imported the Streamlit as st.

Now by calling the st.title() function, we can add a heading to the page with a title design. Let’s say st.title(“This is a next level SEO app”).

Keep in mind that after editing your streamlit_app. py file and saving it, an icon appears in the top right corner of the page, and you should push Constantly returnto view the app changes with no page refresh.

Screenshot from author, October 2022 Now our app appears like the image listed below. If your system style is dark, your app is with a dark theme. Screenshot

from author, October 2022 Add Text To The Streamlit App For adding a text paragraph to the app, you require to utilize the st.write()function. For example, st.write(“Make your ideas genuine”). Screenshot from author, October 2022 Include A Text Input To The Streamlit App As you saw in the Google autocomplete function

, there was an argument called”keyword “. This argument needs to originate from the user input. To get the user input, we can use a text input field

in Streamlit. With st.text _ input(

)we can add a text input. For example, st.text _ input(“What is your seed keyword?”). Likewise, in order to use the input keyword later on to pass to our function, we should assign it to a variable. input_google_autocomplete_keyword: str= st.text _ input( “What is your seed keyword?”)Now we want to run our app when there is an input keyword. Here, we use an if declaration

to check if the variable is empty or not. if input_google_autocomplete_keyword: output_list_google_autocomplete: list [str]=google_autocomplete( input_google_autocomplete_keyword) Screenshot from author, October 2022 Download From The Streamlit App So, we have added a heading, a line of text, and an input text field to get the user seed keyword. Now we should execute our written function and make a download button for the user to get the

results in a text file. if output_list_google_autocomplete: st.download _ button (“Download the output”,(” n”).

join(output_list_google_autocomplete )) Screenshot from author, October 2022 We constructed our basic app! Let’s alter the app title and favicon. Before that

, let’s see the Streamlit app section code up until now. Screenshot from author, October 2022 Change The App Title And Favicon The default title of the app is streamlit_app ยท Streamlit, and

the favicon of the app is the Streamlit icon. To change the title and favicon

, we should use the st.set _ page_config (). Likewise, I prefer the app

design to be large (you can evaluate it). st.set _ page_config

(page_title=”Oh My App!”, page_icon=””, design=”large”) Screenshot from author, October 2022 Set The App’s Default Style The app style is

based upon the user’s system settings,

but personally, most times, I learn the light style has much better contrast– and I do not want my team to put their time into finding out how to alter the app style. To set a default theme for the Streamlit app, first, you should produce a folder, and name

it.streamlit. Inside this folder develop a file, and name it config.toml. Inside the config.toml you must insert the below lines to set your app’s default theme. [. theme] base =”light” Screenshot from author, October 2022 Authenticating Users In Streamlit Picture that after you deploy your app, somebody discovers the app URL

and accesses it. To safeguard your app, you should

authorize the users prior to they can utilize the app– like the majority of SASSs we use every day.

For a Streamlit app, we can use the Streamlit-Authenticator plan. To install it, in the terminal

situated in your app folder, type the pip3 set up streamlit-authenticator command, and import the plan into your app. I suggest you read the Streamlit authenticator plan documentation to get a much better understanding of what is going on. import streamlit_authenticator as stauth Now create a config.yaml apply for inserting our users’credentials. qualifications: usernames: firstUser: e-mail: [email protected] name: The first username password: 12345 # Should be replaced with the hashed password secondUser: email: [email protected] name: The second username password: 111213 # Must be replaced with the hashed password cookie: expiry_days: 30 key: some_signature_key name: some_cookie_name preauthorized: e-mails:[email protected] As in the bundle file you can see, now we need to hash the passwords with the Hasher modules. I prefer to open an IPython and run

the listed below code line. hashed_passwords =stauth.Hasher([ 12345′,’ 111213′]. create ()Creating A Login Widget Now we need to develop a login widget where users can input their username, password, and after that login into the app.

Initially, you need to install the PyYAML package with the pip3 install pyyaml command and import it with the import yaml. Then develop an authenticator things, and render the login module. with open(“./ config.yaml”) as file: config=yaml.load(file, Loader =yaml.SafeLoader)authenticator =stauth.Authenticate(config [“credentials”], config [“cookie”] [“name”], config [“cookie”] [” essential”], config [” cookie “] [” expiry_days”], config [” preauthorized “] name, authentication_status, username=authenticator.login(” Login”, “primary”) Screenshot from author, October 2022 Show The App To Effectively Visited Users Now we can utilize the authentication_status variable to see the app for our effectively logged-in users. if authentication_status: authenticator.logout(‘ Logout’,’main’)# OUR APP CODE COMES HERE

elif authentication_status ==False: st.error(‘Username/password is inaccurate’)elif authentication_status == None: st.warning(‘Please enter your username and password ‘)Deploy The Streamlit App With Docker Now we remain in the last action of developing our app. You can use

various services for releasing your app, like

AWS, Google Cloud, Azure, Heroku, DigitalOcean, and so on.

Prior to the Dockerfile, let’s create the requirements.txt file. To do so, we can use the pip3 freeze > requirements.txt command.

Streamlit Dockerfile For releasing our app, I use Python 3.9.10. FROM python:3.9.10 WORKDIR/ app COPY. RUN pip3 install-r requirements.txt

CMD [“streamlit”

,”run”, “streamlit_app. py”] EXPOSE 8501 Conclude In this tutorial, we saw how we can develop a spectacular UI with pure Python, and release it with Docker. To get more information
