Port Already in Use Error Fix 📛 Don't Do This With Terminal 📛

If you were using terminal or command prompt, closed it later on, but for some reason when you try to use it again, it says: Port 3000 is already in use (something is already running on port 3000) and then you are unable to start the app or use command that you wanted to, then this video is for you. I am using Windows, using Git for Windows for terminal program. I am using React JS app. I will use command npm start This will start the app. I can stop the app by using CTRL + C from keyboard. I can start the app again as normal. If I use the command again and run the app npm start it starts again. If i close the terminal without stopping previous process, it says: Port 3000 already in use or Something is already running on port 3000. We can find specific port (in this case 3000) by using following command on Windows & using Git for Windows netstat -ano | findstr :3000 We can get kill task help by using following command taskkill /? Then I will end process on port 3000 by using this to kill task command taskkill -f -pid 15984 -f flag force kill the running process We can also end running task using npx command in case of React JS or Node JS npx kill-port 3000 You can also kill task from task manager by ending Node JS task. So this is how you can force terminate a task running on a port. When task will be terminated, port will be free and you will be able to use that port again. ✅ Display Data From JSON File in React    • Display Data from JSON File in React JS   ✅ Display Icons / Images from JSON File in React JS    • Display Icons / Images from JSON File in R...   ✅ Fetch All Types of Data from JSON File in React JS    • Fetch All Types of Data from JSON File in ...   ✅ 7 Ways to use Images in React JS    • 7 Ways to Use Images in ReactJS | React Im...   ✅ Easy Way to use Images in React JS    • Easy Way to Use Images in React JS (No Imp...   ✅ Require Image Not Working in React JS    • Require Image Not Working in ReactJS | Ima...   ✅ Multiple Images in One Import    • Multiple Images in ONE IMPORT | ReactJS Tu...   ✅ Multiple Sets of Images from One Import in React JS    • Multiple Sets of Images from ONE IMPORT | ...   ✅ Default Map is not a Function in React JS    • Default MAP is Not a Function | React JS T...   ✅ Async Await Fetch in React JS    • Async Await Fetch Data from API in React J...   ✅ Assigned a Value but Never Used    • Assigned a Value but Never Used | No Unuse...   ✅ Easily Sort Before Displaying Records in React JS    • Sort Data Before Displaying in React JS | ...   ✅ Responsive Image Gallery from Scratch in React JS    • Build Photo Gallery from Scratch in React JS   ✅ ReactJS Playground    • ReactJS Playground   ✅ JavaScript Problem Solving: http://bit.ly/JavsScriptProblemSolving ✅ Web Development Essentials: http://bit.ly/WebDevEssentials ✅ Crash Courses: http://bit.ly/WSPCrashCourses Thank You! 👍 LIKE VIDEO 👊 SUBSCRIBE 🔔 PRESS BELL ICON ✍️ COMMENT Channel:    / webstylepress   Website: https://www.webstylepress.com FaceBook:   / webstylepress   Twitter:   / webstylepress   GitHub: https://github.com/webstylepress #js #reactjs #javascript #react #fix #port #WebStylePress #webdevelopment
