rtcopy is a simple project that uses WebRTC and WebSockets to allow users to temporarily share files in a peer-to-peer (P2P) manner.

To create or access a virtual folder, go to a URL in the following format domain/folder/name/password or domain/folder/name, where name is the name of the virtual folder and pass is an optional password (if not provided, one will be automatically generated).

After accessing the link, the user will enter a page where they can:

• Share local files
• Download files shared by other users connected to the same folder

No file is ever stored on a central server. Once the tab is closed, all access to your local files is revoked and the session ends automatically.

Requirements: Node.js v22.14 or later.

1. Clone the repository:

git clone https://github.com/fcothiago/rtcopy.git

or with SSH.

git clone [email protected]:fcothiago/rtcopy.git

2. Navigate to project directory and use npm to install all the dependencies.

cd rtcopy
npm install

3. Run the project

node src/index.js

By default, the project will run in localhost:7777.

Some parameters of the project can be configured using environment variables. The list below summarizes all available configuration options:

• SERVER_PORT : Configures the port that the server will listen on (default 7777)
• SERVER_URL : The address used to access the project (default: localhost). If you are hosting the project on a platform, you must change this parameter, since each open tab needs to initiate a new WebSocket connection.
• CHUNK_SIZE_BYTES: Number of bytes to be read per data chunk from a file.
• CHUNK_COUNT: Number of chunks to be requested from a user at a time.
