Getting Started

Prerequisites

• Node.js (v14 or later)
• npm (v6 or later)

Installation

1. Install dependencies:

2. Create a .env.local file in the root directory and add the following: TWITTER_BEARER_TOKEN=your_twitter_bearer_token_here

   (Note: This is optional if you're using simulated data)

3. Start the development server: npm run dev

4. Open your browser and navigate to http://localhost:3000

Using Simulated Data vs. Real Twitter Data

Simulated Data (Default)

By default, the application uses simulated data to demonstrate the sentiment analysis functionality. This allows you to run the application without needing Twitter API access.

Using Real Twitter Data

To use real Twitter data:

1. Obtain a Twitter Bearer Token:

• Go to the Twitter Developer Portal
• Create a new project and app
• Generate a Bearer Token for your app

2. Add your Twitter Bearer Token to the .env.local file: TWITTER_BEARER_TOKEN=your_actual_twitter_bearer_token_here

3. Modify the app/api/graphql/resolvers.ts file:

• Comment out the import and usage of generateMockTweets
• Uncomment and update the fetchTwitterData function to use the Twitter API

4. Update the BitcoinSentimentAnalyzer.tsx component:

• Remove references to "simulated" or "mock" data in the UI

5. Restart your development server

Note: Be aware of Twitter API rate limits. The free tier has restrictions on the number of requests you can make.
