FastAPI Tutorial: Beginner to Advanced Python Web API

Deploying a FastAPI app shouldn't take longer than writing your first endpoint. Yet developers still spend hours on ASGI configs, Uvicorn tuning, and SSL certificate setup just to get "Hello World" live. There's a faster way. Our FastAPI deployment guide shows you how to: → Skip the server configuration headaches → Go from local to live in 60 seconds → Get automatic Swagger docs at /docs instantly Stop wrestling with infrastructure. Start shipping. Full guide: https://lnkd.in/dywzJeu5 #FastAPI #Python #WebDevelopment #DevOps #Deployment #API

New Blog Post 😃 In this #CopilotStudio post I share how to make your own MCP Server using Python 🐍 If you’ve never created an MCP Server before you might be surprised how straightforward the building process can be 🏗️ https://lnkd.in/gQav32d4

🚀 Learning FastAPI by Building a Real Project Recently, I built a Notes Application while learning FastAPI, following a tutorial by Code With Harry. 🔹 What I worked on: Created GET & POST routes using FastAPI Connected to MongoDB as the database Used Jinja2 to render HTML templates Built a simple CRUD-based Notes app This project helped me understand how backend APIs work, how to handle data with MongoDB, and how FastAPI can be used with template rendering. Still learning, still building 💪 Github: https://lnkd.in/dbjY33HY #FastAPI #Python #MongoDB #BackendDevelopment #WebDevelopment #LearningByDoing #CodeWithHarry

Continuing my learning-in-public exploration of the Claude Agent SDK. Part 7 is live today. It's almost done after this one. In Part 6, I added permission hooks to control dangerous tool use. This post is about the next step - exposing my own Python functions as tools Claude can call directly. This one covers:  - Creating an in-process MCP server with @tool, create_sdk_mcp_server(), and ClaudeAgentOptions  - Why Claude immediately rewound to the wrong checkpoint - and reusing the permission hooks from Part 6 to fix it  - Some scoping problems - @tool can decorate at import time, but your runtime state doesn't exist yet..

Most full-stack tutorials are drowning in theory, making simple deployments look like a logistical nightmare! 🙃 In my 20-minute quick dive, I’m showing you a clean, result-focused setup - taking a static "Hello World" webpage and transforming it into a production-ready Flask and PostgreSQL application - published and running live on Sevalla! What you'll learn? Building your own tiny social media platform that you can easily share with the world! 🌍🚀 So if you're curious about understanding the flow of data from the database to your app and to the public web - this tutorial is perfect for you!

🚀 Project Showcase: Pastebin-Like Application I built a small Pastebin-like web application that allows users to quickly store and share text content using a unique link. 🔹 Users can paste text and generate a shareable URL 🔹 The content can be viewed using the generated ID 🔹 Supports optional expiration based on time or number of views 🔹 Data automatically expires after the given limit 🛠 Tech Stack: Backend: FastAPI (Python) Database: PostgreSQL (Neon DB) REST API architecture This project helped me strengthen my understanding of backend development, API design, database integration, and real-world application logic. 📹 Sharing a short demo video below 👇 Feedback and suggestions are welcome! #BackendDevelopment #FastAPI #Python #PostgreSQL #APIs #Projects #Learning #SoftwareEngineering Github link :-https://lnkd.in/gXCn8zHq vercel link:-https://lnkd.in/grrzKKUX

Are you ready to level up your backend development skills? I just released a comprehensive 4-hour crash course on FastAPI, one of the fastest-growing and most modern web frameworks for Python today. Whether you’re a Django/Flask fan or coming from a Node.js background like me, this video will show you why FastAPI is a game-changer for building high-performance REST APIs. In this video, we build a real-world Spotify Clone from scratch, covering: Modern Python Tooling: Setting up virtual environments and project structures [09:15]. FastAPI Essentials: Creating your first server, routing, and dynamic path parameters [16:16]. Data Validation: Leveraging Pydantic schemas for cleaner, safer code [02:57]. Database Integration: Connecting to PostgreSQL using SQL Alchemy ORM [02:44]. Security & Auth: Implementing JWT (JSON Web Tokens) and protecting routes [03:56:07]. Auto-Documentation: Using the built-in Swagger UI to test your endpoints instantly [04:58]. Watch the full course here: https://lnkd.in/dugZbs7u I’ve designed this to be a hands-on experience, starting from a "Hello World" to building complex relationships and authentication [03:57:56]. If you find the video helpful, please consider subscribing to the channel and leaving a comment—it really helps the algorithm reach more developers like you! Happy coding, Haider Malik

📅 Day 24 – File Uploads & Downloads in FastAPI 📂🚀 As part of my Python Django Revision & FastAPI Learning Journey, today I focused on handling real-world file operations inside backend applications — an essential feature for modern APIs. 🔹 Key Learnings Uploading Images & Files Implemented secure file upload handling using FastAPI, understanding how applications manage user-generated content. File Validation Learned to validate file types, sizes, and formats to ensure security, reliability, and clean data handling in production systems. Static File Serving Explored how to serve uploaded files efficiently using static file configuration — a crucial concept for media delivery in web applications. 💡 Takeaway Robust file handling is a core backend responsibility. Proper validation, secure uploads, and efficient static serving are key to building scalable and production-ready APIs. Step by step, strengthening my foundation in FastAPI, backend architecture, and real-world application development. 🔥 #Python #FastAPI #Django #BackendDevelopment #FileUpload #APIDevelopment #SoftwareEngineering #LearningJourney #100DaysOfCode #Python #Django #Docker #BackendDevelopment #WebDevelopment #FullStackDevelopment #FullStackDeveloper #SoftwareDevelopment #Programming #Coding #PythonDeveloper #DjangoDeveloper #DjangoORM #DjangoRESTFramework #DjangoProjects #RESTAPI #APITesting #AutomationTesting #QualityAssurance #BugFixing #Postman #TestCases #EmailAutomation #EmailIntegration #SMTP #SendGrid #NotificationSystem #ApplicationEmails #BackendFeatures #DockerCompose #Containerization #DevOps #CloudComputing #SoftwareDeployment #Microservices #ScalableSystems #100DaysOfCode #100DaysCodingChallenge #DailyCoding #CodingChallenge #CodeEveryday #LearningJourney #TechLearning #ContinuousLearning #KeepLearning #Upskilling #SelfLearning #PracticeMakesPerfect #BuildInPublic #LearningInPublic #PersonalProjects #RealWorldProjects #ProjectBasedLearning #DeveloperJourney #DeveloperLife #TechJourney #GrowthMindset #FromStudentToDeveloper #CareerGrowth #ITDevelopment #SoftwareEngineering #ProblemSolving

🚀 **Day 29 – Testing FastAPI | Python Django Revision & FastAPI Learning Journey** Today’s focus was on **ensuring backend reliability through testing** — a crucial step before deploying any production-ready API. 🔍 **Key Learnings:** • Understanding the importance of **testing in FastAPI applications** • Writing test cases using **Pytest** for clean and scalable validation • Using **TestClient** to simulate real API requests and responses • Differentiating between **Unit Tests vs Integration Tests** and knowing when to use each • Building confidence in delivering **stable, bug-free backend systems** Testing is not just about finding bugs — it’s about **building trust in the system before users ever see it**. Every day of this journey is bringing me closer to designing **production-ready, scalable backend architectures**. 💡 Consistency + Practice = Real Growth. #FastAPI #Python #Django #BackendDevelopment #APITesting #Pytest #SoftwareTesting #IntegrationTesting #UnitTesting #WebDevelopment #LearningJourney #100DaysOfCode
