How to Use the Hacker News Reader Template
Introduction to the Template
The Hacker News Reader template is designed to help you build a client application for reading and interacting with Hacker News. This template includes a responsive header, a home page that displays top stories from Hacker News, and the necessary backend setup to fetch and render these stories.
Clicking Start with this Template
To get started with the Hacker News Reader template, click Start with this Template in the Lazy Builder interface.
Test
After starting with the template, press the Test button. This will begin the deployment of the app and launch the Lazy CLI. The CLI will guide you through any required user input.
Using the App
Once the app is deployed, you can use the interface to view the top stories from Hacker News. The app includes a responsive header that adapts to both mobile and desktop views.
- Mobile View: The mobile header includes a menu button that toggles the visibility of the navigation links.
- Desktop View: The desktop header displays the navigation links directly.
Integrating the App
This app does not require any external integration steps. It is a standalone client application that fetches and displays top stories from Hacker News.
Code Overview
Here is a brief overview of the key components in the template:
HTML Templates
- _mobile_header.html: Contains the mobile-specific header with a menu button.
- _desktop_header.html: Contains the desktop-specific header with navigation links.
- _header.html: Combines the mobile and desktop headers into a responsive header.
- home.html: The main page that displays the top stories from Hacker News.
JavaScript
- header.js: Handles the toggling of the mobile menu.
- home.js: Placeholder for any home page-specific JavaScript.
CSS
- styles.css: Contains custom styles and imports for Tailwind CSS and Flowbite.
Python
- main.py: Sets up and runs the Flask application using Gunicorn.
- routes.py: Defines the route for fetching and displaying top stories from Hacker News.
- app_init.py: Initializes the Flask application and registers routes.
Requirements
- requirements.txt: Lists the Python dependencies required for the app.
Sample Code
Here is a sample code snippet from the routes.py file that fetches and displays top stories from Hacker News:
```python from flask import render_template, request from flask import current_app as app import requests
def register_routes(app): @app.route("/") def home_route(): # Fetch top stories from Hacker News API top_stories_url = "https://hacker-news.firebaseio.com/v0/topstories.json" top_stories = requests.get(top_stories_url).json()[:30] # Get top 30 stories
stories = []
for story_id in top_stories:
story_url = f"https://hacker-news.firebaseio.com/v0/item/{story_id}.json"
story = requests.get(story_url).json()
stories.append(story)
return render_template("home.html", stories=stories)
```
This code fetches the top 30 stories from the Hacker News API and renders them on the home page.
Conclusion
By following these steps, you can easily set up and deploy the Hacker News Reader app using the Lazy platform. The template provides a responsive interface and fetches real-time data from Hacker News, making it a useful tool for staying updated with the latest stories.
