FilmGuru’s journey begins with my movie database, a CSV file sourced from Kaggle, containing 8,000 movie records with details like descriptions, year, and other metadata. Here’s how it all comes together:
I started by uploading the CSV to Timescale as a new service, which took just 2 minutes to complete.
Using the SQL editor, I added a primary key column to the table—this is crucial for utilizing Timescale’s pgvectorizer functionality.
I then used the vectorizer with OpenAI’s embedding model (small) to generate embeddings instantly across the entire database, creating a vector representation for each movie entry to allow FilmGuru to find the best matches based on your preferences.
The original CSV file included fields for title, description, year, duration, rating, and stars, among others. I kept only these essential fields, discarding the rest. Since the movie descriptions were quite lengthy, I divided them into chunks, adding key contextual fields to each chunk to retain as much relevant information as possible.
async function Vectorizer() {
try {
await pool.query(
`
SELECT ai.create_vectorizer(
'public.imdb_numbered_votes'::regclass,
embedding=>ai.embedding_openai('text-embedding-3-small', 1536, api_key_name=>'OPENAI_API_KEY'),
chunking=>ai.chunking_recursive_character_text_splitter('description'),
formatting=>ai.formatting_python_template('title: $title description: $chunk, year: $year, duration: $duration, rating: $rating, stars: $stars')
);
`,
);
return { status: "success" };
} catch (error) {
console.log(error);
return { status: "failed" };
}
}
Behind the Scenes of Your Recommendation Journey
When you enter a prompt (like "I want something like Inception"), it’s sent to the backend server.
The server uses pg AI to create a unique embedding for your query with the help of OpenAI's text-embedding-3-small, transforming it into a vector.
FilmGuru then uses pgvector to search the database for movies with similar embeddings, delivering the closest match as your next recommendation.
It’s seamless, fast, and incredibly fun!
Final Thoughts
The project came up smooth. I only had one dependency in my back end. That was the pg library for postgres. Kinda cool that I could build the entire backend just with one library.
I’m planning to add an agent that fetches images for each movie, making recommendations even more visually engaging. Stay tuned!
