Are you tired of being stuck on the same old login page after a successful authentication? Do you want to take your Streamlit app to the next level by navigating to a different page after login? Look no further! In this comprehensive guide, we’ll show you how to achieve this feat with ease.
Why Navigate to a Different Page after Login?
There are several reasons why you might want to navigate to a different page after login:
- Improved User Experience: By redirecting users to a specific page after login, you can provide a more personalized experience and reduce clutter.
- Enhanced Security: Navigating to a different page after login can help prevent unauthorized access and reduce the risk of session hijacking.
- Streamlined Workflows: By directing users to a specific page after login, you can simplify workflows and reduce the number of clicks needed to perform a task.
Prerequisites
Before we dive into the tutorial, make sure you have the following prerequisites:
- Streamlit installed: You need to have Streamlit installed on your machine. If you haven’t installed it yet, you can do so by running
pip install streamlit
in your terminal. - Basic understanding of Streamlit: You should have a basic understanding of Streamlit and how it works. If you’re new to Streamlit, we recommend checking out the official documentation before proceeding.
Step 1: Create a Login Page
First, let’s create a basic login page using Streamlit. Create a new file called login.py
and add the following code:
import streamlit as st st.title("Login Page") username = st.text_input("Username") password = st.text_input("Password", type="password") if st.button("Login"): # Add your login logic here st.write("Login successful!")
This code creates a simple login page with two input fields for username and password, and a login button. When the login button is clicked, it writes “Login successful!” to the screen.
Step 2: Create a Dashboard Page
Next, let’s create a dashboard page that we’ll navigate to after a successful login. Create a new file called dashboard.py
and add the following code:
import streamlit as st st.title("Dashboard") st.write("Welcome to the dashboard!") st.button("Logout")
This code creates a simple dashboard page with a title and a logout button.
Step 3: Redirect to Dashboard after Login
Now, let’s modify the login page to redirect to the dashboard page after a successful login. Update the login.py
file with the following code:
import streamlit as st import streamlit.components.v1 as components st.title("Login Page") username = st.text_input("Username") password = st.text_input("Password", type="password") if st.button("Login"): # Add your login logic here st.write("Login successful!") # Redirect to dashboard page components.html(f""" """, height=0)
In this updated code, we added a components.html
block that injects a JavaScript script into the page. The script sets the window.location.href
property to dashboard.py
, which redirects the user to the dashboard page.
Step 4: Run the App
Finally, let’s run the app by executing the following command in your terminal:
streamlit run login.py
This will launch the Streamlit app and display the login page. Enter your credentials, click the login button, and you’ll be redirected to the dashboard page!
Troubleshooting Common Issues
If you encounter any issues while implementing this tutorial, here are some common troubleshooting tips:
- Make sure you’re running the latest version of Streamlit: Ensure that you’re running the latest version of Streamlit by checking the official documentation.
- Check your code for syntax errors: Make sure there are no syntax errors in your code by running it through a Python linter or IDE.
- Verify your login logic: Double-check your login logic to ensure it’s correct and functioning as expected.
- Clear your browser cache: Sometimes, browser cache can cause issues with Streamlit apps. Try clearing your browser cache and retrying the app.

What if I want to redirect to a page that requires authentication?
If you want to redirect to a page that requires authentication, you’ll need to use a library like `streamlit-authenticate` to handle authentication and authorization. Once the user is authenticated, you can use the `st.write` function to redirect to the protected page.
Can I use a Python function to redirect to a different page?
Yes, you can use a Python function to redirect to a different page. Simply define a function that uses the `st.write` function to write the HTML redirect tag, and then call the function after login. For example: `def redirect_to_new_page(): st.write(‘‘)`.
How do I pass parameters to the new page after redirect?
You can pass parameters to the new page by adding them to the URL as query parameters. For example: ``. Then, on the new page, you can use the `st.experimental_get_query_params` function to retrieve the query parameters.
What if I want to redirect to a page that’s not a Streamlit app?
If you want to redirect to a page that’s not a Streamlit app, you can use the `st.write` function to write an HTML redirect tag that points to the external URL. For example: ``. Note that this will redirect the user to a page outside of the Streamlit app.
