Rate-limiting API Endpoint using Bucket4j in Spring
Tags: springboot, apisecurity, java, security
Published: 2023-12-31 21:49:26

**Overview**

In this article, you will learn how to implement a rate limit. Our focus will be to implement a rate limit for an endpoint using the Bucket4j library.

**Rate-Limiting API**

There are different reasons to apply a rate limit to an API endpoint. One of many reasons would be to implement a rate limit based on the subscription plan on a system; another is that the request to login endpoint should be controlled from a unique request source, thereby regulating the number of requests made within a few minutes, as this can allow individuals with bad intent to carry out brute force attacks on your server, thereby leading to a server crash and making your application unavailable to users.

**Bucket4J Library**

Bucket4j is a Java rate-limiting library that is mainly based on the token-bucket algorithm. The token bucket algorithm enables a network to allow or deny requests based on current traffic. Each bucket holds a certain number of tokens that represent network requests (e.g., attempting to log into an account or sending a message). Whenever a user sends a request, another token gets added to the bucket.

Since the bucket has a set limit on how many tokens it can hold, the algorithm stops operations if users make too many requests in a short time. The network drops all new requests until a "bucket refill" resets the number of allowed tokens.

**Using Bucket4j Library to Limit Endpoint**

Using the Bucket4j library is very simple, though it might get complex with more needed control. First, we need to setup a Spring application using the Spring initializr. Add the Spring web dependency. One additional dependency is the bucket4j library. Here is snippet to add to pom

<dependency>
<groupId>com.bucket4j</groupId>
<artifactId>bucket4j-core</artifactId>
<version>8.1.0</version>
</dependency>

Below are a few lines of code that just implemented rate limiting on the home endpoint. This is how simple it can be.

**Code Snippet**

```
@RestController
@RequestMapping
public class RateLimiting {
Bucket bucket;
@GetMapping("/house")
public void initializeBucket() {
Refill refill = Refill.intervally(3, Duration.ofMinutes(1));
Bandwidth limit = Bandwidth.classic(3, refill);
bucket = Bucket.builder()
.addLimit(limit)
.build();
}
@GetMapping("/home")
public ResponseEntity<?> login() {
if(bucket.tryConsume(1)) {
System.out.println("Success");
return ResponseEntity.ok("Successful");
} else {
System.out.println("Too many requests");
return ResponseEntity.status(HttpStatus.TOO_MANY_REQUESTS).build();
}
}
}
```

Get ready, developers, because the future is upon us. Let's take a look at these technological wonders that await us. Spoiler: it's almost like reinventing the wheel.

So, Web 3.0 is the next big thing, huh? They say it will decentralize everything, giving power back to the people. As if Web 2.0 wasn't enough, where everyone became "influencers" without making a dime. But now, brace yourselves for user autonomy and all this blockchain magic.

As we gaze into the digital horizon of 2024, the advent of Web 3.0 beckons a revolutionary shift. It goes beyond being a conventional update, daring to reshape the very fabric of the internet. This transformation hinges on the ethos of decentralization, ushering in an era where users wield unprecedented control.

At the core of this transformation lies the formidable blockchain technology. As we brace for 2024, blockchain isn't merely a buzzword but a force driving change. Its secure and transparent nature sets the stage for a paradigm shift. Smart contracts, entwined with blockchain, herald an era of automated and trustless agreements, reshaping digital interactions in profound ways.

In the upcoming digital landscape of 2024, the decentralization of data takes center stage. No longer confined to the clutches of corporate giants, data is set to be distributed across a decentralized network. This shift empowers users with direct ownership and control over their data, heralding a new era of digital empowerment.

As we stand on the brink of 2024, the Web 3.0 promises a landscape that transcends convention.

Did you realize that over 50% of your skills often come from outside your 9-to-5 job? 😮 

It's mind-boggling, right?

I've realized that some of my most valuable learnings and skills haven't necessarily stemmed from my main job, but from diving into side projects. 

These projects have been like a playground where I get to experiment, learn new technologies, and challenge myself in ways my regular job might not allow.

For instance, last year, I was working on a side project to create a mobile app for managing personal finances. While my main job didn't involve mobile development, this project allowed me to explore new programming languages, and user interface design, and even delve into the complexities of security in finance apps. The experience I gained was invaluable and boosted my confidence in tackling diverse challenges.

This year, I started tinkering with a personal project - an app idea that had been floating in my mind for ages. Not only did it let me apply what I knew, but it pushed me to learn new languages and frameworks too! 

Whether it's building a website, experimenting with a new framework, creating a fun app, or contributing to an open-source project, side projects can be your playground for growth.

They're like a sandbox where you can freely explore, make mistakes, and level up your skills.

So, my advice to all of you incredible engineers out there: 

Don't underestimate the power of side projects!🙌 

They're not just hobbies but incredible opportunities to upskill and expand your knowledge base. 

Seize the opportunity to grow beyond the confines of your job description and explore the endless possibilities that your creativity can lead you to.

MVP is not Minimum Viable Product
Tags: startup
Published: 2023-12-31 19:58:11

MVP is the acronym for “Minimum Viable Product.” That’s correct.

However, MVP does not mean minimum viable products. It’s a very common mistake that startups make.

Here's why.

## What does MVP mean?

The idea is that we need

> A version of a new product which allows a team to collect the maximum amount of **validated learning** about customers with the least **effort**. — <The Lean Startup>, Eric Ries
> 

That’s a golden idea, but the use of the word "product" can easily confuse people. If your goal is to make an electric car, you may want to build a smaller and simpler version and call it a product. However, that’s incorrect.

According to the definition, an MVP is something that can maximize the value of

{% katex %}
\frac{validated\ learning\  about\ customers}{effort}
{% endkatex %}

It could be anything. Think out of the box.

## What could a MVP?

Does such a thing have to be a **product** in the form you’re thinking? Not really.

Let’s say there is a game that has been pre-ordered one million times and raised 100 million because of that. Would you think the propagation of that game has provided **validated learning about customers**? Does it matter that there could be just a video without a single line of code? No, it doesn’t. The idea of the game has been fully proven by customers’ real money. So, this is a successful MVP because with the **effort** of making a video (which takes a few weeks), they gathered feedback from customers.

## What else could be a MVP

**Surveys**. You can learn what features customers like or dislike, how much money they’re willing to pay for a specific feature.

**Videos**. Post a video on YouTube and see if people are excited about it. Tweets and posts on different forums are the same idea.

**Crowdfunding**. If you can convince others about your production idea, you probably should pursue it.

**VC**. Venture Capital firms are the best people to evaluate your production idea. They can’t tell you what’s a good product, but they usually can point out what are bad ones.

Basically, it could be anything. A rule of thumb is pushing back building a real product as much as possible. The easy mistake is jumping directly into doing a real thing. This is especially common for people who are engineers.
