Building My First Steamlit App

Mark McFate — Mon, 24 Jul 2023 18:44:51 +0000

I’ve been wanting to give Streamlit a try for some time now. Recently, I found Streamlit DataScience Apps, a GitHub repo full of Streamlit apps, written by Jcharis. In particular, I thought I would take the Job_Search_App_with_Streamlit_Forms_n_GithubAPI code for a spin.

First step, I created a new ~/GitHub/ code directory on my Mac; I named my directory ~/GitHub/job-search-app-with-streamlit-forms. The plan was to work in that directory inside VSCode with all the project requirements housed in a Python virtual environment (.venv) there.

The command stream in my terminal looked like this:

╭─mark@Marks-Mac-Mini ~
╰─$ cd ~/GitHub
╭─mark@Marks-Mac-Mini ~/GitHub
╰─$ mkdir job-search-app-with-streamlit-forms
╭─mark@Marks-Mac-Mini ~/GitHub
╰─$ cd job-search-app-with-streamlit-forms
╭─mark@Marks-Mac-Mini ~/GitHub/job-search-app-with-streamlit-forms
╰─$ code .

That last command opened the new directory in VSCode where I had all the tools I needed, including a new terminal window. In that window I continued with…

╭─mark@Marks-Mac-Mini ~/GitHub/job-search-app-with-streamlit-forms 
╰─$ python3 -m venv .venv

╭─mark@Marks-Mac-Mini ~/GitHub/job-search-app-with-streamlit-forms 
╰─$ source .venv/bin/activate

(.venv) ╭─mark@Marks-Mac-Mini ~/GitHub/job-search-app-with-streamlit-forms 
╰─$ pip3 install streamlit

  DEPRECATION: validators is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

Mackenzie says I need to remove the beta_ in two places in the code… Done.

Launching the app again with streamlit run app.py after a moment or two it works!

Streamlit Apps Fork

Mark McFate — Mon, 05 Jun 2023 12:31:46 +0000

This morning I found some new Streamlit resources from developer Jcharis, and I forked his Jcharis/Streamlit_DataScience_Apps to make my own copy at SummittDweller/Streamlit_DataScience_Apps

Now I’m going to try and get the component Simple_CRuD_Blog_App_with_Streamlit working locally as a proof-of-concept. Since I can’t “clone” the single project repo, and a “sparse checkout” seems wasteful since I’ll never push back to the original project, I’m going to git init an entirely new local named simple-CRuD-blog-app-with-streamlit and just copy/paste the contents.

It works!

I’ve got Mackenzie looking at Streamlit as a means of building a mobile-friendly app that I can use to create posts like this one. That app will need to allow me to edit a TITLE and Markdown BODY fields, capture location and time, and post all of that information to my personal blog… preferably from my cell phone. I’ve captured some possible resources and guidance in https://www.one-tab.com/page/71iaDADxT-eLEOx15qeVnQ.
