How does Spring Boot simplify development?
Spring Boot simplifies Java development by offering a streamlined, production-ready framework that reduces boilerplate code and configuration complexities. It is built on top of the Spring Framework but eliminates much of the setup and manual configurations required in traditional Spring applications. This leads to faster development, easier deployment, and improved productivity.
One of the core features of Spring Boot is its auto-configuration. Instead of manually defining beans or XML configurations, Spring Boot automatically configures your application based on the libraries present in your classpath. For example, if you include Spring Data JPA, it auto-configures database settings, assuming typical defaults, which can still be overridden as needed.
Spring Boot also comes with an embedded web server (like Tomcat, Jetty, or Undertow). This means developers can run web applications without deploying WAR files to an external server—just run the application as a Java program, and it serves content directly. This makes testing, debugging, and deployment much faster and simpler.
Additionally, Spring Boot includes starter dependencies, which are curated dependency sets for common tasks like web development, security, and data access. These starters remove the guesswork from version compatibility and help avoid dependency conflicts.
Another significant feature is the Actuator, which provides out-of-the-box endpoints for monitoring and managing applications. Developers can check application health, view metrics, and track usage statistics without writing custom code.
Spring Boot promotes opinionated defaults, meaning it guides developers toward best practices and proven design patterns, allowing them to focus more on business logic than infrastructure code.
Because of these advantages, Spring Boot is a critical skill for modern web application development in Java. Anyone aiming to master backend technologies should consider enrolling in a java full stack developer course to build strong expertise in Spring Boot and related technologies.

Top 7 Skills to Become A Full-Stack Developer in 2025
With the ever-increasing pace of technological change, the need for techies with multidisciplinary skills has never been higher. One of the most sought-after jobs in the tech field today is that of a Full-Stack Developer̶ one who could smartly trick both front and back-end development. By 2025, this position promises to be even more dynamic and skill-intensive than before, requiring the developers to be multi-talented, flexible, and always learning. Thus, whether you are just stepping into this profession or you're enhancing your skill set, full stack web development entails mastering as many skills as possible to stay relevant.
Let us check out the top 7 crucial skills that every full-stack developer should develop by 2025. Front-End Expertise The user interface is the first thing people see and interact with--that's why we call this front-end work fundamental. A full-stack developer must have a good working knowledge of HTML, CSS, and JavaScript, the trifecta of front-end development. For 2025, developers who know tools like React.js, Vue.js, and Next.js are in ever-increasing demand, as these frameworks can be used to develop dynamic, highly performant, and mobile-responsive web applications. One should also know a little about aspects such as responsive design and various browser compatibilities. Grasping concepts related to state management on the front end (for example, using Redux, Zustand, or the React Context API) boosts one's professional profile, with companies recognizing these competencies.
Strong Back-End Knowledge While the front-end sees what the user gets, the back-end makes things run in the background. Full-stack developers should command the lease on server-side programming using languages such as JavaScript (Node.js), Python (Django/Flask), Java (Spring Boot), or Ruby on Rails. You would need to know how to build RESTful APIs and work with user sessions, authentication, and authorization with communications to a database. Keeping in mind the social aspect of security and data integrity, it is also important for any practice to involve the rest-audit trail, validation, error handling, etc. Knowledge of cloud platforms like AWS, Google Cloud, or Azure would be an added advantage for deploying a scalable back end.
Database Management Every full-stack developer must have some hardcore database skills. It doesn't matter if it is the relational database world of MySQL or PostgreSQL or the advanced NoSQL world of MongoDB, you need to know how to work with schema design, efficient query writing, and database connection management. In 2025, a developer must know the difference between structured and unstructured data and know when to use what type of database. Indexing, normalization, and transactions will become especially critical to you as you build scalable applications. ORMs (Object Relational Mappers) like Sequelize or Mongoose are also crucial for streamlining code/database interaction.
Understanding of APIs APIs (Application Programming Interfaces) are the glue that binds together the various pieces of a system. A full-stack developer should be able to build and consume APIs. Although REST is still the most-used tool, GraphQL has emerged as an alternative technology due to its speed and flexibility. To properly build and solve any API issues, an understanding of Postman or Insomnia as tools is necessary. Familiarity with authentication methods, such as OAuth2.0, JWT (JSON Web Tokens), and API key management, secures your applications while they communicate with the different services.
Version Control Working on software projects without version control is akin to tight-rope walking without a safety net. Developers can use Git tools to track changes or collaborate more efficiently and roll back to previous versions and full-stack developers should know Git well enough to create branches and merge code to resolve conflicts and manage pull requests. Beyond 2025, GitHub, GitLab, and Bitbucket will be more relevant to the work process of the teams. Apart from collaboration, knowing Git shows the power and the discipline in practice concerning coding.
Performance Optimization Your web app must not just work, but also work fast. Performance optimization is nowadays inevitable in an era where user experience rules. On the front ends, such performance optimization encompasses reduced render time, reduced bundle size, lazy loading of components, or using CDNs. Back-end-side optimizations include the use of caching systems such as Redis, optimization in database query usage, and using effective server-side rendering methodologies. A full-stack developer should know how to use performance monitoring tools, such as Lighthouse and Google Web Vitals, and also backend profiling tools to identify and resolve bottlenecks.
Problem-Solving & Soft Skills: While technical skills are backbone assets in development, soft skills with problem-solving capabilities do much more to separate the wheat from the chaff in talented developers. This also includes proficiency in debugging codes and high-level thinking with systematic approaches toward solving problems in everyday development. Just as essential are communication, working as a team, and working in an agile environment. More and more, employers are looking for people who work as teammates but can also adjust easily to keep pace with ever-changing requirements, while contributing positively to the dynamics of a team.
Take up a Course: If in 2025, you really want to be a Full-Stack Developer, going for a regular course is going to be an accelerator in your skills. Make sure you find one that comes with hands-on projects, industry tools, and mentorship from seasoned pros. The course should be extensive — everything from HTML and JavaScript to back-end programming and deployment. Practical experience is the name of the game; the course should emphasize building an entire web application from scratch.
Conclusion Being a full-stack developer in 2025 will entail much more than just coding: it means knowing how every part of a web application fits together-from the user interface to the database. Mastering the above-mentioned seven basic skills will ensure your position as a really well-capable and competitive developer in today's technology-enriched world.

A Guide to Creating APIs for Web Applications
Tumblr media
APIs (Application Programming Interfaces) are the backbone of modern web applications, enabling communication between frontend and backend systems, third-party services, and databases. In this guide, we’ll explore how to create APIs, best practices, and tools to use.
1. Understanding APIs in Web Applications
An API allows different software applications to communicate using defined rules. Web APIs specifically enable interaction between a client (frontend) and a server (backend) using protocols like REST, GraphQL, or gRPC.
Types of APIs
RESTful APIs — Uses HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources.
GraphQL APIs — Allows clients to request only the data they need, reducing over-fetching.
gRPC APIs — Uses protocol buffers for high-performance communication, suitable for microservices.
2. Setting Up a REST API: Step-by-Step
Step 1: Choose a Framework
Node.js (Express.js) — Lightweight and popular for JavaScript applications.
Python (Flask/Django) — Flask is simple, while Django provides built-in features.
Java (Spring Boot) — Enterprise-level framework for Java-based APIs.
Step 2: Create a Basic API
Here’s an example of a simple REST API using Express.js (Node.js):javascriptconst express = require('express'); const app = express(); app.use(express.json());let users = [{ id: 1, name: "John Doe" }];app.get('/users', (req, res) => { res.json(users); });app.post('/users', (req, res) => { const user = { id: users.length + 1, name: req.body.name }; users.push(user); res.status(201).json(user); });app.listen(3000, () => console.log('API running on port 3000'));
Step 3: Connect to a Database
APIs often need a database to store and retrieve data. Popular databases include:
SQL Databases (PostgreSQL, MySQL) — Structured data storage.
NoSQL Databases (MongoDB, Firebase) — Unstructured or flexible data storage.
Example of integrating MongoDB using Mongoose in Node.js:javascriptconst mongoose = require('mongoose'); mongoose.connect('mongodb://localhost:27017/mydb', { useNewUrlParser: true, useUnifiedTopology: true });const UserSchema = new mongoose.Schema({ name: String }); const User = mongoose.model('User', UserSchema);app.post('/users', async (req, res) => { const user = new User({ name: req.body.name }); await user.save(); res.status(201).json(user); });
3. Best Practices for API Development
🔹 Use Proper HTTP Methods:
GET – Retrieve data
POST – Create new data
PUT/PATCH – Update existing data
DELETE – Remove data
🔹 Implement Authentication & Authorization
Use JWT (JSON Web Token) or OAuth for securing APIs.
Example of JWT authentication in Express.js:
javascript
const jwt = require('jsonwebtoken'); const token = jwt.sign({ userId: 1 }, 'secretKey', { expiresIn: '1h' });
🔹 Handle Errors Gracefully
Return appropriate status codes (400 for bad requests, 404 for not found, 500 for server errors).
Example:
javascript
app.use((err, req, res, next) => { res.status(500).json({ error: err.message }); });
🔹 Use API Documentation Tools
Swagger or Postman to document and test APIs.
4. Deploying Your API
Once your API is built, deploy it using:
Cloud Platforms: AWS (Lambda, EC2), Google Cloud, Azure.
Serverless Functions: AWS Lambda, Vercel, Firebase Functions.
Containerization: Deploy APIs using Docker and Kubernetes.
Example: Deploying with DockerdockerfileFROM node:14 WORKDIR /app COPY package.json ./ RUN npm install COPY . . CMD ["node", "server.js"] EXPOSE 3000
5. API Testing and Monitoring
Use Postman or Insomnia for testing API requests.
Monitor API Performance with tools like Prometheus, New Relic, or Datadog.
Final Thoughts
Creating APIs for web applications involves careful planning, development, and deployment. Following best practices ensures security, scalability, and efficiency.

What’s the Difference Between Front-End and Back-End Development? 
Tumblr media
Web development is all about building websites and applications, and it’s divided into two main parts: front-end and back-end development. These two work together to make websites look good and function properly, but they have different tasks, tools, and skills. Let’s explore the differences in a simple way.
What is Front-End Development?
Front-end development is everything on a website or app that you can see and click on, like buttons, images, text, and menus. It’s all about making the website look nice and easy to use, so users can easily navigate and interact with it.
Example: When you visit a website and click on a button, the design you see and the way the button works is the result of front-end development.
Key Responsibilities of a Front-End Developer
Designing the user interface (UI): Creating how the website looks and making sure it's easy to use.
Making designs work on all devices: Ensuring the website looks good on phones, tablets, and computers.
Adding interactivity: Making the website interactive with things like buttons, menus, and animations.
Languages and Frameworks
Core Languages
HTML: Builds the structure of a website.
CSS: Styles the website with colors, fonts, and layout.
JavaScript: Adds interactivity like dropdowns and sliders.
Frameworks and Libraries
React.js: Used for building dynamic websites.
Angular: A powerful tool for building complex apps.
Vue.js: A simple and flexible tool for modern websites.
Bootstrap: Helps design websites that work well on all devices.
What is Back-End Development?
Back-end development is everything that happens behind the scenes on a website. It makes sure the website works properly by managing things like data storage and the server. When you do something on a website, like clicking a button or submitting a form, the back-end makes sure the right information is processed and sent where it needs to go.
Example: When you log into a website, the back-end makes sure your username and password are correct, finds your information in a storage system, and lets you into your account.
Key Responsibilities of a Back-End Developer
Managing Data: A back-end developer makes sure that data is stored safely and can be retrieved when needed.
Writing Code for the Server: They write the instructions that tell the website how to process actions, like when a user submits a form.
Making the Website Fast and Safe: They ensure the website works quickly and securely, protecting it from potential problems.

The Connection Between Front-End and Back-End
Front-end and back-end work together to ensure the website functions correctly:
Front-End Role: When you visit an education website, the front-end shows you things like course listings, a search bar, and a login form to register or sign in.
Back-End Role: When you search for a course or log in, the back-end processes your request, checks the available courses in the database, and verifies your login details.
Front-End Role: After the back-end processes everything, the front-end shows you the list of courses or confirms your login and takes you to your student dashboard.
For example, when you want to enroll in a course, the front-end displays the course options. Once you select a course, the back-end checks if you're eligible, processes your enrollment, and confirms it. The front-end then shows your updated enrollment status.

Provide insights into securing Java web and desktop applications.
Tumblr media
Securing Java web and desktop applications requires a combination of best practices, security libraries, and frameworks to prevent vulnerabilities like SQL injection, XSS, CSRF, and unauthorized access. Here’s a deep dive into key security measures:
1. Secure Authentication and Authorization
Use Strong Authentication Mechanisms
Implement OAuth 2.0, OpenID Connect, or SAML for authentication.
Use Spring Security for web applications.
Enforce multi-factor authentication (MFA) for added security.
Example (Spring Security Basic Authentication in Java Web App)java@Configuration @EnableWebSecurity public class SecurityConfig { @Bean public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { http .authorizeHttpRequests(auth -> auth .requestMatchers("/admin/**").hasRole("ADMIN") .anyRequest().authenticated()) .httpBasic(); return http.build(); } }Implement Role-Based Access Control (RBAC)
Define roles and permissions for users.
Use JWT (JSON Web Tokens) for securing APIs.
Example (Securing API using JWT in Spring Boot)javapublic class JwtUtil { private static final String SECRET_KEY = "secureKey"; public String generateToken(String username) { return Jwts.builder() .setSubject(username) .setIssuedAt(new Date()) .setExpiration(new Date(System.currentTimeMillis() + 1000 * 60 * 60)) .signWith(SignatureAlgorithm.HS256, SECRET_KEY) .compact(); } }
2. Secure Data Storage and Transmission
Use Secure Communication (HTTPS & TLS)
Use TLS 1.2+ for encrypting data in transit.
Enforce HSTS (HTTP Strict Transport Security).
Encrypt Sensitive Data
Store passwords using bcrypt, PBKDF2, or Argon2.
Use AES-256 for encrypting sensitive data.
Example (Hashing Passwords in Java)javaimport org.mindrot.jbcrypt.BCrypt;public class PasswordSecurity { public static String hashPassword(String password) { return BCrypt.hashpw(password, BCrypt.gensalt(12)); } public static boolean verifyPassword(String password, String hashedPassword) { return BCrypt.checkpw(password, hashedPassword); } }
Use Secure Database Connections
Use parameterized queries to prevent SQL injection.
Disable database user permissions that are not required.
Example (Using Prepared Statements in JDBC)javaPreparedStatement stmt = connection.prepareStatement("SELECT * FROM users WHERE username = ?"); stmt.setString(1, username); ResultSet rs = stmt.executeQuery();
3. Protect Against Common Web Vulnerabilities
Prevent SQL Injection
Always use ORM frameworks (Hibernate, JPA) to manage queries securely.
Mitigate Cross-Site Scripting (XSS)
Escape user input in web views using OWASP Java Encoder.
Use Content Security Policy (CSP) headers.
Prevent Cross-Site Request Forgery (CSRF)
Use CSRF tokens in forms.
Enable CSRF protection in Spring Security.
Example (Enabling CSRF Protection in Spring Security)javahttp.csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
4. Secure File Uploads and Deserialization
Validate File Uploads
Restrict allowed file types (e.g., only images, PDFs).
Use virus scanning (e.g., ClamAV).
Example (Checking File Type in Java)javaif (!file.getContentType().equals("application/pdf")) { throw new SecurityException("Invalid file type"); }
Avoid Untrusted Deserialization
Use whitelisting for allowed classes.
Prefer JSON over Java serialization.
Example (Disable Unsafe Object Deserialization in Java)javaObjectInputStream ois = new ObjectInputStream(inputStream) { @Override protected Class<?> resolveClass(ObjectStreamClass desc) throws IOException, ClassNotFoundException { throw new InvalidClassException("Deserialization is not allowed"); } };
5. Secure Desktop Java Applications
Use Code Signing
Sign JAR files using Java Keytool to prevent tampering.
shjarsigner -keystore mykeystore.jks -signedjar SecureApp.jar MyApp.jar myaliasRestrict JavaFX/Swing Application Permissions
Use Java Security Manager (deprecated but useful for legacy apps).
Restrict access to file system, network, and system properties.
Encrypt Local Data Storage
Use AES encryption for storing local files.
Example (Encrypting Files with AES in Java)javaCipher cipher = Cipher.getInstance("AES"); cipher.init(Cipher.ENCRYPT_MODE, new SecretKeySpec(key, "AES")); byte[] encrypted = cipher.doFinal(data);
6. Logging and Monitoring for Security
Use Secure Logging Frameworks
Use logback or SLF4J.
Avoid logging sensitive data like passwords.
Monitor for Anomalies
Implement Intrusion Detection Systems (IDS).
Use audit trails and security alerts.
7. Best Practices for Securing Java Applications
✅ Keep dependencies up to date (Use OWASP Dependency Check). ✅ Run security scans (SAST, DAST) using SonarQube, Checkmarx. ✅ Apply the principle of least privilege for database and API access. ✅ Enforce strong password policies (min length, special characters). ✅ Use API Gateway and rate limiting for public-facing APIs.
Conclusion
Securing Java web and desktop applications requires multi-layered security across authentication, data protection, and vulnerability mitigation. By following best practices like strong encryption, secure coding techniques, and continuous monitoring, developers can protect applications against cyber threats.

Fireworks || Darth Vader x Reader
Tumblr media
(A/N ***please read if you havent read the epilouge to my series*** : yes hi I wanted this to go out earlier but oopsie ig lmao, but I was inspired by the fireworks of last night so yuhhh :))) This is based off my vader x reader series, but not canon to the story!! (or maybe it is, i’ll let you be the judge of that). for those of you who havent read the epilogue of my series Far Away, Together, all you need to know is that vader and his bby yeeted out the empire and now are living in the middle of nowhere together :)) taglists are open, enjoy!!)
(P.S.: if you wanna read the epilogue, you can find it here, as well as all the other chapters of FaT)
WARNINGS: None!! Very fluffy
Key: (F/N) = first name 
Word Count: ~3200
~~~
You both always hated it when you had to go to the wreckage, but you both knew that you had to. 
After fixing your love a nice lunch and leaving him to eat in his meditation chamber, you begrudgingly pulled on your going-out clothes, a slight frown on your face all the while. Pulling on your walking boots and securing your tools to your belt, you heard your love’s meditation chamber open and close, alongside his heavy footsteps drawing closer and closer to you. Your hearing perking up, you noticed how he stopped in the doorway without having to turn your head. 
You smiled to yourself. You could feel his gaze on you, warming your heart. 
“When do you plan to return, darling?” Vader asked you, his voice as deep and rumbling as ever. If this had been some years ago, you would have been scared. But now, all you felt was warmth. 
Maker, you were so in love. 
“I’ll be back before sundown, Vee.” you responded without turning to him, combing out your hair with your fingers. 
You could practically feel how much he didn’t like that. It made the air thick yet almost uncomfortably sharp at the same time. Your smile faded a little at this. You hated leaving for so long just as much as he did, but you had to go. His bacta tank had been acting funky recently, and you had finally narrowed the problem down to the filter. 
And, of course, you were all out of filters. 
This meant you had to go to the wreckage of the crashed Star Destroyer to find a new one, or at least the parts you needed to make one. 
Your favorite activity. 
Your smile now completely faded away, you reached inside one of your dresser drawers, retrieving out a long, black cloth from it. The ends of the cloth were heavily tattered and torn, and there were even large holes in some areas. 
His old cape. 
Since he hardly wore it anymore, you took it over as your own. He had long since abandoned the black one for a medium-toned blue one you had made him not too long ago. He told you that he wore that one because you had made it, but you knew the real reason. 
After the Empire fell, he wanted to shed as much of the past as possible, and did this little by little. It started with his cape, but has slowly branched out to other means. 
For example, his saber. 
��Take my weapon with you, dear. Use it to protect yourself while I am not present.” you heard him say as you fastened his old cape around your shoulder such that the cloth ran diagonally across your body, scraping only slightly on the floor. Turning to face him, you smiled up at his mask, the sound of his steady breath filling your ears. 
He always worried about you. Ever since you had professed your love for one another, he seemed to never stop worrying. You would ordinarily tease him for things like this, but you knew better in this situation. You knew he had lost so many in his life… 
And you knew losing you would destroy him, once and for all. 
So, it was clear to you why he troubled himself so much about you. And it was even clearer why this worry was even greater when you had to make these trips. He couldn’t come with you, much to your shared disdain. The hike would be too strenuous on him. Even though he had survived his encounter with his old master…
It still did a large number on his health. 
You didn’t want to shorten his lifespan, so you made these trips by yourself. 
Even though you both knew this and accepted it, this didn’t stop his worry. He always made you take his saber with you, even if you had your own blaster. 
Stepping closer to your love, your eyes stayed upon his mask as you took one of his hands into your own, pressing a soft kiss on the leather of his gloves as he looked down upon your face. Looking back up to meet his gaze, a small, warm smile enveloped your features. 
Vader wondered how someone could be so damn perfect. 
“I will, don’t worry.” you assured him, “Where is it?” 
“I have placed it in our safe, my sweet.” he rumbled out, his gaze unable to falter from off of your frame. 
Giving him a firm nod and standing on your tip-toes, you placed a small peck on the cheek of his mask before pushing past him, the tatters of his old cape upon your shoulders fluttering in the breeze of your steps. 
Vader almost never carried his saber anymore. The crimson blade only reminded him of the past. He only seemed to wield it if he sensed some sort of danger threatening to disrupt your shared home. These instances were often in the middle of the night, and often woke you up from your sleep. And, even more often, there was absolutely no danger. 
He was always so hard to calm down on those nights…
And even harder to convince to go back to sleep. 
Stopping your steps in front of the safe, your knelt down in front of its door, punching in the code to open it as you felt his presence draw behind you. Reaching in, you wrapped your hands around the cool, polished metal of the hilt of his saber, attaching it to your belt as you closed the safe and stood up again. Turning on your heel, you were a bit spooked when you realized just how close he was. Taking a tiny step back, you looked up at his mask. 
He seemed… off. 
Even more so than usually when you had to go out. 
Feeling his shift in mood, you shot up a warm smile at him before turning your gaze to the cape around his shoulders. Reaching your hands up, you took the blue cloth into your hands, smoothing it out as you spoke. 
“Vee, I’ll be fine. I’ve done this a million times before, and there’s always nothing out there.” you tried to reassure him. 
“I am aware, my dear.” he rumbled out. 
Despite him not having much flavor to the inflections in his deep voice, you knew he wasn’t convinced. Moving your hands from his lapel to his mask, you cradled the metal in your palms, making him meet your gaze. 
“Then there’s no need to worry, hmm?” 
Gazing down at you in a long moment of silence, Vader contemplated your words. You wondered if he would ever say anything, but were quickly met with an answer as he placed his much larger hands upon yours. 
“I suppose not…” he finally said. 
You breathed out a smile as he continued. 
“But please do be careful, my sweet. I shall eagerly await your return.” 
Letting out a soft giggle, you gave him a broad, dopey smile as you spoke your response. 
“Whatever you say, loverboy.” 
~~~
The hike to the wreckage had left you sweaty and sore. It always did, but this didn’t stop you from complaining silently to yourself. Wiping the sweat that moistened your brow, you gazed upon the familiar wreckage for a moment before stepping inside, watching the ground to avoid any missteps. 
The filters were usually located in the old medical bay of the old Star Destroyer. Fortunately, the walk from the entrance to the demolished medical bay wasn’t all that far. However, it was extremely dark. The power of this ship had gone out long ago, and darkness had quickly made it’s new home in it's dilapidated walls. Your pupils widening in the dark, you reached down to your belt, pushing your cape out of the way. 
Your hand finding a long, cool cylinder of metal, you shot out a quick smile as your fingers wrapped around it. 
Your love always was there for you, to guide you in the dark. 
Unclipping the saber from your belt, you made sure to point the tip away from you as you pushed the igniter, springing the weapon to life. With a continuous, dull humm, the crimson of the blade illuminated your face in red, as well as your nearby surroundings. Wrapping your other hand around the hilt, you held your love’s weapon firmly as you made your way through the wreckage, following the red light that surrounded you. 
Trailing on for a long while, you were eventually met with the old medical wing. Securing the saber into your left hand, you held it above your head as you pushed the doors open, the metal making an awful squeak as you did so. 
Searching around the cracked and damaged storage bins and compartments of the old unit, you were pleased when you found a clean, unused filter. Hissing out a quiet yes to yourself, you took Vader’s old cape from off your shoulders and placed it on the ground. Putting the filter on top of the cloth, you made a make-shift bag out of the cape. 
Bunching up the fabric and slinging it over your shoulder, you jumped as you heard a crash from behind you. Letting out a yelp and turning on your heel quickly, your heart started to race as you gripped both hands onto the crimson blade’s hilt, ready to strike at any moment. 
When you were greeted with nothing but the sight of wreckage, you let your shoulders relax. Your heartrate slowing, you realized that there were no intruders or critters there to kill you. Dropping your gaze to the floor, you were met with the sight of a knocked-over crate. Focusing your eyes harder, you noticed an odd substance spilling out of the crate. 
Kneeling down, you kept your lover’s saber above your head as you went in for a closer look. Your eyes adjusting in the red light, you were able to make out what the substance was. 
Powder. 
Overcome by your curiosity, you reached your hand down and took a few granules of the powder in between your pointer finger and thumb. Rubbing your two phalanges together as you brought them closer to your face, your eyebrows raised as you finally were able to deduce what it was. 
Black powder. 
Shifting your gaze down to the contents of the knocked-over crate, you saw that there were other tubes of other types of powders from a plethora of different materials. 
Seeing these items struck an old chord deep inside you. You were familiar with what they would do when mixed together, but this familiarity was sourced from a long, long time ago. All the way back from when the empire was just forming. All the way back from your home planet…
As the memories flooded your mind, you felt the grip you had on your love’s saber tighten without you having to think about it. Realizing this, your lips parted as the beginnings of an idea formed in your mind. Letting it form for a few more moments, you smiled softly as you slipped the cape-bag off of your shoulders and opened it up, placing a few canisters of powder into it alongside the filter. 
Tonight would be a good night for you and him. 
~~~
Just as you had promised, you were back to the house before sundown. In fact, the excitement you felt from your idea coupled with the promise of returning to him made you come back before the sun had even begun to set, your steps having a certain pep to them. 
Pushing open the door to your shared home, you called out an I’m home as you closed it behind you. Almost instantly, you heard the sound of his boots thudding over to you, alongside the sound of his respirator. Setting down his saber on a small table, you noticed in your peripheral a large, looming, black figure watching you from afar. A smile forming on your face, you turned your head towards the figure. 
Your love. 
You could tell from the aura around him that he was happy you were home again. 
“(F/N),” he rumbled out, a hint of amusement in his voice, “How was your voyage?”
“It was good.” you responded, adjusting the cape-bag on your shoulder as you kicked off your boots, “I found another filter, and even a little surprise for later.” 
Your love tilted his armored head at this. He often did when he was curious.
He was too damn cute sometimes. 
“A surprise?” he asked. 
“Yes, a surprise, Vee.” you said as you walked up to him, standing on your tiptoes to press a soft, quick kiss on his mask’s cheek as you walked past him to the living area. 
Turning to face you, your love stayed put as he spoke, his gaze seemingly unable to falter off of your frame as you poured your bag’s contents out on the floor and sat in front of it. 
“What is it, darling?” he asked, making you breathe out a giggle as you glanced up at him. 
“If I tell you, then it won’t be a surprise anymore.” you said. 
You could tell he was miffed as you saw his shoulders and posture stiffen. You could only smile as you started to poke through the items you had brought home. 
“I wish to know what you are scheming, my dear.” he rumbled out. 
You giggled again. Maker, you found him almost too damn cute. 
“You’ll find out eventually what I’m scheming, love.” you said as you began to unscrew the lids to the powder canisters, “I promise you’ll like it.” 
“I do not doubt that, my sweet.”
“Then stop fretting.” you giggled again, “Come on, you can help by keeping me company while I set this up.” 
Realizing that he would get absolutely nowhere by pestering you further, Vader gave in to your scheme. Entering into the living room, he found a place where he could comfortably watch you work. 
Watching you do what you were best at was one of his favorite pass-times. 
And knowing what you were doing was for him only made it better. 
~~~
He was spending some time in his meditation chamber when you finished. Instead of immediately getting him out of there, you took the opportunity to set up your scheme, as he called it.
Taking a blanket out of your storage closet, you picked up your scheme alongside the cloth and carried it outside. Finding a nice clearing of grass, you laid out the blanket in just the right spot.
It was now night time, and the cool breeze of the darkness made your hair sway as you set up your scheme. Once it was all finished, you stood up from your crouching position, looking out on the fields of  your new home planet with a small smile on your face. 
It was the perfect night. It was the perfect night for him. The stars were as bright as ever, and the rich blues and blacks of night accented the green of the vegetation so very well. 
This was all for him. You loved him endlessly, and you dedicated yourself to making the rest of his days as comfortable as possible. He had been through so, so much… 
And you hoped that nights like this would help him accept everything and move on. 
Maker above, did you try so hard to make him accept the past. 
But you didn’t mind. 
Not one bit. 
Dusting off your hands, you headed back inside once everything was complete. Making your way into your shared bedroom, you focused your gaze upon the meditation pod that took up nearly half of the space. Slowly but surely, you reached up your hand and knocked gently on the metal. 
“Vee?” you called out, hoping you weren’t disturbing him too much, “Your surprise is ready, if you wanna come out…” 
After a moment, the metal of the pod finally raised up with a sharp hiss, causing you to take a step back. Watching him rise from his seated position and begin the motions of stepping out, you stepped forward. Taking one of his hands into yours and draping your arm across his back, you helped him step down from the pod, giving him support in case he started to feel weak. 
“Have you finished your scheme, darling?” he asked you once he was stable. 
You breathed out a smile, keeping his hands secure in your own. 
“Yes, love. My scheme is done,” you said, “Come on, come see.” 
With that, you turned on your heel and led him by the hand outside. You could feel that he was perplexed, but pushed on anyway. You only stopped once you reached the blanket you had laid out. 
“Here we are,” you cooed, “Take a seat, Vee.” 
Following your request, he shifted his weight to sit upon the blanket, leaning some of it upon you as you helped him be seated. Taking a seat next to him, you reached out and grabbed a panel of buttons you had thrown together that evening. Fiddling with the panel, Vader looked down at you as you worked, feeling his heart swell with awe and pride. 
He had never been so in love. 
“Do you wish to finally tell me what this plot is, my dear?” he asked, making you smile. 
“Yes, I do.” you responded without looking up from the buttons. 
“Then please, enlighten me.” 
Letting out a giggle at his teasing vocabulary, you spoke your response. 
“Well, in my home village, we called them color rockets, but you probably know them as fireworks. We would make our own and launch them on holidays or days of harvest…” 
Pressing one final button, the sound of one of your home-made fireworks launching filled your ears. Shifting your gaze to the sky, your smile broadened as you saw the streaks of color illuminate the night, the hues reflecting on your skin and in yours eyes. 
Looking to him, your eyes softened with warmth as  you continued. 
“Or, we would make them as a token of love for our partners.”
Vader couldn’t even begin to think of something to say in that moment. He was unquestionably, undeniably, and totally speechless. 
You were so damn beautiful. Both inside and out, your beauty outshone even the brightest stars in the galaxy. Even though the two of you had been together for years now, he still wondered why you chose him of all people. You were so good, and when the two of you met… 
He wasn’t. 
Not in the slightest. 
He was cruel. 
Mean. 
Unforgiving. 
Evil. 
Yet still, even through all the bad, even through all his baggage, even through all the moments where his past came back to haunt him…
You stayed with him. Supported him, even…
Loved him, even. 
And  maker above did he love you for it. 
Alongside all the other million reasons why he loved you. 
He hoped that you didn’t mind that he didn’t know what to say in that moment. The way you smiled up at him and looked at him said that you didn’t, and that was all the confirmation he needed. Reaching up his hand, he placed it upon your cheek, holding your face as gently as he could. He felt his heart swell as your smile broadened as you leaned into his touch, placing your small hands on top of his own. 
Maker above, if Lord Vader were able to stop time…
He would do it in this exact moment. 
Never in his life had he felt so at peace…
So in love…
So relaxed…
So...
Free.
