Building My First Steamlit App
2023-07-24 - ~5 Minutes
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!
