Quickstart

Setup Lightning Charge, then:

# Install dependencies for EXIF extraction and preview generation
$ apt install exiftool ffmpeg graphicsmagick unoconv

# Install dependencies for node-canvas (see https://github.com/Automattic/node-canvas#installation)
$ apt install libcairo2-dev libjpeg8-dev libpango1.0-dev libgif-dev build-essential g++

# Install filebazaar
$ npm install -g filebazaar

# Prepare a directory with the files you wish to sell and cd to it
$ mkdir ~/ForSale && cd ~/ForSale

# Initialize the `_filebazaar.yaml` config file
$ filebazaar init

# Edit the config file (`charge_token` is required, `token_secret` is auto-generated)
$ edit _filebazaar.yaml

# Start filebazaar!
$ filebazaar

Configuration

FileBazaar's configuration options can be managed using the _filebazaar.yaml file or via environment variables. All config options are optional and have sane defaults except for charge_token and token_secret, which are required. See lib/config.js for more details.

Below is an example _filebazaar.yaml file:

  Media/: # (note the trailing slash)
    Books/Andreas/:
      Mastering-Bitcoin.pdf: 5 USD # /Media/Books/Andreas/Mastering-Bitcoin.pdf
      The-Internet-of-Money.pdf: 4 USD # /Media/Books/Andreas/The-Internet-of-Money.pdf

CLI

Initializing _filebazaar.yaml

You can use $ filebazaar init [directory] to initialize a new _filebazaar.yaml config file. A random token_secret will be added for you. If no [directory] is specified, the file will be created in the working directory.

Running FileBazaar

To start FileBazaar, run $ filebazaar [path]. You can either specify the path to the files directory or to the _filebazaar.yaml file. If no [path] is specified, defaults to the working directory.

File Preview

FileBazaar can currently generate previews for the following file types:

  • Images: a preview image will be generated by pixelating the left half of the image and adding watermark text using node-canvas and graphicsmagick (see example image).

  • Videos & audio: a preview will be generated by slicing off the first 30 seconds using ffmpeg.

  • Documents: a preview image of the first page of the document will be generated using unoconv (supports pdf, doc, docx, odt, and many others).

In addition, EXIF metadata will be extracted using exiftool and displayed for all file types.
