Node With Express and Redis

In this course, you’ll get an introduction to Node.js and Express.js. You’ll learn about large language models—including how a general LLM works, OpenAI’s GPT model, and its APIs with Node.js. You’ll also learn about Redis to implement API rate limiting. You’ll then gain hands-on, practical experience via three applied projects. The first involves building a Q&A bot using the PDF document to understand embeddings. The second includes building a YouTube video summarizer app to understand speech-to-text processing using OpenAI’s Whipser model. The final project is tol build a Twitter tweet generator to learn image generation with Redis’s role in managing API rate limits.

After taking this course, you can develop intelligent and scalable applications using OpenAI APIs, Redis, and Node.js.

It provides strong data consistency guarantees.

It reduces database load by storing frequently accessed data.

It offers complex data querying capabilities.

It enforces data integrity through schema definitions.

What is a primary benefit of using Redis as a caching system?

What is a primary benefit of using Redis as a caching system?

What is the output of the following code:

```js
await redisClient.incr('user_1');
await redisClient.incr('user_1');
await redisClient.incr('user_1');
const output_one = await redisClient.get('user_1');
console.log(output_one);
await redisClient.incr('user_1');
await redisClient.set('user_1', 11);
await redisClient.incr('user_1');
const output_two = await redisClient.get('user_1');
console.log(output_two);
```

What is the output of the following code:
<pre><code class="language-js">await redisClient.incr('user_1');
await redisClient.incr('user_1');
await redisClient.incr('user_1');
const output_one = await redisClient.get('user_1');
console.log(output_one);
await redisClient.incr('user_1');
await redisClient.set('user_1', 11);
await redisClient.incr('user_1');
const output_two = await redisClient.get('user_1');
console.log(output_two);

What is a common use case for incrementing a variables in Redis?

What is a common use case for incrementing a variables in Redis?

It automatically replicates data to slave nodes.

It clears all data from a specific data store.

It deletes all keys in the current data store without confirmation.

 It requires downtime for the Redis server.

What is the potential risk associated with using the `FLUSHALL` command?


What is the potential risk associated with using the <code>FLUSHALL</code> command?

It throws an error message indicating the key doesn't exist.

It automatically creates the key with a default value.

It returns a random value already stored in the database.

What happens when you use the `GET` command on a non-existent key in Redis?

What happens when you use the <code>GET</code> command on a non-existent key in Redis?
