1. Introduction to Mesop
Mesop is a Python-based UI framework that simplifies web UI development, making it an ideal choice for engineers working on AI and machine learning projects without extensive frontend experience. By leveraging Angular and Angular Material components, Mesop accelerates the process of building web demos and internal tools.
Key Features of Mesop:
- Python-Centric Development: Build entire UIs in Python without needing to dive into JavaScript.
- Hot Reload: Enjoy a fast build-edit-refresh loop for smooth development.
- Comprehensive Component Library: Utilize a rich set of Angular Material components.
- Customizability: Extend Mesop’s capabilities with custom components tailored to your use case.
- Easy Deployment: Deploy using standard HTTP technologies for quick and reliable application launches.
2. Getting Started with Mesop
To begin your journey with Mesop, follow these steps:
- Install Mesop via pip:
pip install mesop - Create a new Python file for your project, e.g.,
app.py. - Import Mesop in your file:
import mesop as me
3. Building Your First Mesop UI
Let’s create a simple multi-page UI for an AI-powered note-taking app:
import mesop as me
@me.page(path="/")
def home():
with me.box():
me.text("Welcome to AI Notes", type="headline")
me.button("Create New Note", on_click=navigate_to_create)
@me.page(path="/create")
def create_note():
with me.box():
me.text("Create a New Note", type="headline")
me.text_input("Note Title")
me.text_area("Note Content")
me.button("Save", on_click=save_note)
def navigate_to_create(e):
me.navigate("/create")
def save_note(e):
# Implement note-saving logic here
pass
if __name__ == "__main__":
me.app(port=8080)This example illustrates how easily you can set up a multi-page app with Mesop. Using @me.page, you define different routes, while components like me.text and me.button bring the UI to life.
4. Advanced Mesop Techniques
As your app grows, you’ll want to use advanced Mesop features to manage complexity:
State Management
Mesop’s @me.stateclass makes state management straightforward:
@me.stateclass
class AppState:
notes: list[str] = []
current_note: str = ""
@me.page(path="/")
def home():
state = me.state(AppState)
with me.box():
me.text(f"You have {len(state.notes)} notes")
for note in state.notes:
me.text(note)Custom Components
Keep your code DRY by creating reusable components:
@me.component
def note_card(title, content):
with me.box(style=me.Style(padding=me.Padding.all(10))):
me.text(title, type="subtitle")
me.text(content)5. Integrating AI and LLM RAG with Mesop
Now, let’s add some AI to enhance our note-taking app:
import openai
@me.page(path="/enhance")
def enhance_note():
state = me.state(AppState)
with me.box():
me.text("Enhance Your Note with AI", type="headline")
me.text_area("Original Note", value=state.current_note)
me.button("Generate Ideas", on_click=generate_ideas)
def generate_ideas(e):
state = me.state(AppState)
response = openai.Completion.create(
engine="text-davinci-002",
prompt=f"Generate ideas based on this note: {state.current_note}",
max_tokens=100
)
state.current_note += "\n\nAI-generated ideas:\n" + response.choices[0].textThis integration showcases how OpenAI’s GPT-3 can enrich user notes with AI-generated ideas.
6. Optimizing Performance and Adaptivity
Mesop excels at creating adaptive UIs that adjust seamlessly across devices:
@me.page(path="/")
def responsive_home():
with me.box(style=me.Style(display="flex", flex_wrap="wrap")):
with me.box(style=me.Style(flex="1 1 300px")):
me.text("AI Notes", type="headline")
with me.box(style=me.Style(flex="2 1 600px")):
note_list()
@me.component
def note_list():
state = me.state(AppState)
for note in state.notes:
note_card(note.title, note.content)This setup ensures that the layout adapts to different screen sizes, providing an optimal user experience.
7. Real-World Case Study: AI-Powered Research Assistant
Let’s build a more complex application: an AI-powered research assistant for gathering and analyzing information:
import mesop as me
import openai
from dataclasses import dataclass
@dataclass
class ResearchTopic:
title: str
summary: str
sources: list[str]
@me.stateclass
class ResearchState:
topics: list[ResearchTopic] = []
current_topic: str = ""
analysis_result: str = ""
@me.page(path="/")
def research_home():
state = me.state(ResearchState)
with me.box():
me.text("AI Research Assistant", type="headline")
me.text_input("Enter a research topic", on_change=update_current_topic)
me.button("Start Research", on_click=conduct_research)
if state.topics:
me.text("Research Results", type="subtitle")
for topic in state.topics:
research_card(topic)
@me.component
def research_card(topic: ResearchTopic):
with me.box(style=me.Style(padding=me.Padding.all(10), margin=me.Margin.bottom(10), border="1px solid gray")):
me.text(topic.title, type="subtitle")
me.text(topic.summary)
me.button("Analyze", on_click=lambda e: analyze_topic(topic))
def update_current_topic(e):
state = me.state(ResearchState)
state.current_topic = e.value
def conduct_research(e):
state = me.state(ResearchState)
# Simulate AI research (replace with actual API calls)
summary = f"Research summary for {state.current_topic}"
sources = ["https://example.com/source1", "https://example.com/source2"]
state.topics.append(ResearchTopic(state.current_topic, summary, sources))
def analyze_topic(topic: ResearchTopic):
state = me.state(ResearchState)
# Simulate AI analysis (replace with actual API calls)
state.analysis_result = f"In-depth analysis of {topic.title}: ..."
me.navigate("/analysis")
@me.page(path="/analysis")
def analysis_page():
state = me.state(ResearchState)
with me.box():
me.text("Topic Analysis", type="headline")
me.text(state.analysis_result)
me.button("Back to Research", on_click=lambda e: me.navigate("/"))
if __name__ == "__main__":
me.app(port=8080)This case study shows how to integrate AI capabilities into a responsive UI, allowing users to input research topics, receive AI-generated summaries, and conduct in-depth analyses.
