Dcoder - A Competitive Programming Portal

• Dcoder platform is created for programmers.

• User is able to add,edit and delete the questions which are added by himself only. Other users can only read these questions. Also, users can simply use a compiler built in our website and compile/run their code. Users can save multiple codes. One user can’t see the other user's code.

• There are a lot of programming platforms out there each with their own contest, for one programmer it’s hard to keep a map of every contest date, time and duration. This project will help them to see all the contest information at a single place.

• This project uses the MERN stack :

  • Mongoose.js (MongoDB) : database
  • Express.js : backend framework
  • React.js : frontend library
  • Node.js : runtime environment

• Other tools and technologies used :

  • Bootstrap : layout and styles
  • Font Awesome : icons
  • Moneco Editor : code editor
  • Kontests : api for upcomming contests data

• Profile images store in Cloudinary

Functionality

• Register, Login / Logout
• Compile and Run your Code
• Nice Code editor
• Code Save and Sharing via link
• DSA questions
• Upcoming contest information
