Bolt 🔩

Bolt is a simple and fast http proxy living in the Erlang VM. Bolt can be used as a SSL proxy to prevent mixed content warnings on secure pages or to bypass CORS. For example as a SSL image proxy or html proxy for client side website scraping.

Installation

1. Install dependencies with mix deps.get
2. Start Phoenix endpoint with mix phoenix.server

or

Usage

Pipe your requests through

http://example.com/?url=<url>

SSL

If you need to use your own certificate:

To launch your application with support for SSL, just place your keyfile and certfile in the priv directory and configure your router with the following options

# bolt/config/prod.exs
use Mix.Config

config :phoenix, Bolt.Endpoint,
  https: [port: 443,
          host: "example.com",
          keyfile: System.get_env("SOME_APP_SSL_KEY_PATH"),
          certfile: System.get_env("SOME_APP_SSL_CERT_PATH")],
  ...

When you include the otp_app option, Plug will search within the priv directory of your application. If you use relative paths for keyfile and certfile and do not include the otp_app option, Plug will throw an error.

You can leave out the otp_app option if you provide absolute paths to the files.

Example:

Path.expand("../../../some/path/to/ssl/key.pem", __DIR__)
