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. If you're accessing the web server remotely, you probably also want to set host and url. See lib/config.js for more details.

Below is an example _filebazaar.yaml file:

charge_url: http://localhost:9112
charge_token: API_TOKEN_CONFIGURED_IN_CHARGE

      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:

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