<!-- ABOUT THE PROJECT -->

## 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

<a href="https://nodejs.org" target="_blank"> <img src="https://devicons.github.io/devicon/devicon.git/icons/nodejs/nodejs-original-wordmark.svg" alt="nodejs" width="40" height="40"/> </a>
<a href="https://www.docker.com/" target="_blank"> <img src="https://devicons.github.io/devicon/devicon.git/icons/docker/docker-original-wordmark.svg" alt="docker" width="40" height="40"/> </a>

<!-- GETTING STARTED -->

## 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 <container_id> /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 EXAMPLES -->

## 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

<!-- ABOUT THE PROJECT -->

## 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

<a href="https://nodejs.org" target="_blank"> <img src="https://devicons.github.io/devicon/devicon.git/icons/nodejs/nodejs-original-wordmark.svg" alt="nodejs" width="40" height="40"/> </a>
<a href="https://www.docker.com/" target="_blank"> <img src="https://devicons.github.io/devicon/devicon.git/icons/docker/docker-original-wordmark.svg" alt="docker" width="40" height="40"/> </a>

<!-- GETTING STARTED -->

## 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 <container_id> /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 EXAMPLES -->

## 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

<!-- ABOUT THE PROJECT -->

## 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

<a href="https://nodejs.org" target="_blank"> <img src="https://devicons.github.io/devicon/devicon.git/icons/nodejs/nodejs-original-wordmark.svg" alt="nodejs" width="40" height="40"/> </a>
<a href="https://www.docker.com/" target="_blank"> <img src="https://devicons.github.io/devicon/devicon.git/icons/docker/docker-original-wordmark.svg" alt="docker" width="40" height="40"/> </a>

<!-- GETTING STARTED -->

## 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 <container_id> /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 EXAMPLES -->

## 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

<!-- ABOUT THE PROJECT -->

## 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

<a href="https://nodejs.org" target="_blank"> <img src="https://devicons.github.io/devicon/devicon.git/icons/nodejs/nodejs-original-wordmark.svg" alt="nodejs" width="40" height="40"/> </a>
<a href="https://www.docker.com/" target="_blank"> <img src="https://devicons.github.io/devicon/devicon.git/icons/docker/docker-original-wordmark.svg" alt="docker" width="40" height="40"/> </a>

<!-- GETTING STARTED -->

## 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 <container_id> /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 EXAMPLES -->

## 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

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

```
```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 <container_id> /bin/bash
```
6. Build the Images inside the Container
```sh
cd Dockerfiles
```
```sh

```
<!-- USAGE EXAMPLES -->

## 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
