+ + + +## About The Project + +This is the server-side code of a Remote Code Executor. This is a project assigned by the Coding forum of my college and is similar to the Online IDEs of websites like CodeChef and Leetcode. + +Salient Features: + +- Code Sanitisation +- An individual Docker Container is created for every code posted on the API, so no code interferes with any other code +- All Async code so that the server can handle multiple requests without error + +### Built With + + nodejs + docker + + + +## Getting Started + +To get a local copy up and running follow these simple steps. + +### Prerequisites + +- npm + ```sh + npm install npm@latest -g + ``` +- docker + ```sh + curl -fsSL https://get.docker.com -o get-docker.sh + ``` + ```sh + sudo sh get-docker.sh + ``` + +### Installation +#### If you are on a Linux(preferably Ubuntu) Machine +1. Clone the repo + ```sh + git clone https://github.com/rajatmaheshwari2512/remote-code-exec + ``` +2. Install NPM packages + ```sh + npm install + ``` +3. To build the docker images + ```sh + cd Dockerfiles + ``` + ```sh + docker build -t cpp:v1 -f DockerCPP . + ``` + ```sh + docker build -t python:v1 -f DockerPython . + ``` + ```sh + docker build -t java:v1 -f DockerJava . + ``` +#### If you are on any other Machine +1. Clone the repo + ```sh + git clone https://github.com/rajatmaheshwari2512/remote-code-exec + ``` +2. Install NPM packages + ```sh + npm install + ``` +3. Build the Server's Dockerfile + ```sh + docker build -t rceserver:v1 . + ``` +4. Run the Docker Image + ```sh + docker run --privileged=true -v /var/run/docker.sock:/var/run/docker.sock -d -p 3000:3000 rceserver:v1 + ``` +5. Create a shell to the created Docker Container + ```sh + docker ps + ``` + ```sh + docker exec -it /bin/bash + ``` +6. Build the Images inside the Container + ```sh + cd Dockerfiles + ``` + ```sh + docker build -t cpp:v1 -f DockerCPP . + ``` + ```sh + docker build -t python:v1 -f DockerPython . + ``` + ```sh + docker build -t java:v1 -f DockerJava . + ``` + + +## Usage + +1. To run the server in dev mode use + ```sh + npm run dev + ``` +2. To run the server in production mode + ```sh + npm start + ``` +3. Note that dev mode uses nodemon so that the server can be changed and restarted easily + + + +## Roadmap + +See the [open issues](https://github.com/rajatmaheshwari2512/remote-code-exec/issues) for a list of proposed features (and known issues). + + + +## Contributing + +Contributions are what make the open source community such an amazing place to be learn, inspire, and create. Any contributions you make are **greatly appreciated**. + +1. Fork the Project +2. Create your Feature Branch (`git checkout -b feature/AmazingFeature`) +3.
