Judge0 IDE

Quickstart

Judge0 IDE up and running quickly:

1. Setting Host and Port To ensure Judge0 IDE connects to the correct backend host, configure the defaultUrl in ide/js based on your environment:

   • Local Setup: If running Judge0 IDE locally, set defaultUrl to localhost:port.
   • Remote Setup: If deploying to a remote server, set defaultUrl to your server's address, e.g., remote:port.

   Adjusting this setting will allow the IDE to connect properly depending on whether it is running locally or remotely.

2. Start Judge0 IDE

   docker-compose up -d db redis
   sleep 10s
   docker-compose up -d
   sleep 5s

By default, the IDE web interface will open on port 8085. You can change this in docker-compose.yml. If you modify the port or host for Nginx, remember to also update the defaultUrl in ide/js.
