ssb-viewer

HTTP server for read-only views of SSB content. Serves content as web pages or as scripts for embedding in other web pages.

Install & Run

As a sbot plugin:

mkdir -p ~/.ssb/node_modules
cd ~/.ssb/node_modules
git clone ssb://%MeCTQrz9uszf9EZoTnKCeFeIedhnKWuB3JHW2l1g9NA=.sha256 ssb-viewer && cd ssb-viewer
npm install
sbot plugins.enable ssb-viewer
# restart sbot

Or standalone:

git clone ssb://%MeCTQrz9uszf9EZoTnKCeFeIedhnKWuB3JHW2l1g9NA=.sha256 ssb-viewer && cd ssb-viewer
npm install
./bin.js

Usage

To view a thread as a web page, navigate to a url like http://localhost:8807/%MSGID.

To embed a thread into another web page, load it as follows:

<script src="http://localhost:8807/%MSGID.js"></script>

To add more than the base styles, you can also load http://localhost:8807/static/nicer.css.

Routes

• /%msgid: web page showing a message thread
• /%msgid.js: script to embed a message thread
• /%msgid.json: message thread as JSON
• /&feedid: web page showing a complete feed
• /user-feed/&feedid: web page showing messages from followed users and channels of a feed
• /channel/#channel: web page showing messages in a specific channel

Query options

• noroot: don't include the root message in the thread
• base=...: base url for links that ssb-viewer can handle
• msg_base=...: base url for links to messages
• feed_base=...: base url for links to feeds
• blob_base=...: base url for links to blobs
• img_base=...: base url for embedded blobs (images)
• emoji_base=...: base url for emoji images

The *_base query options overwrite the defaults set in the config. The base option is a fallback instead of specifying the URLs separately. The base options are mostly useful for embedding, where the script is embedded on a different origin than where ssb-viewer is running. However, you may not need them, as the ssb-viewer embed script will detect the base where it is included from.

Config

To change ssb-viewer's default options, edit your ~/.ssb/config, to have properties like the following:

{
  "viewer": {
    "port": 8807,
    "host": "::"
  }
}

You can also pass these as command-line options to ./bin.js or sbot as, e.g. --viewer.port 8807.

• viewer.port: port for the server to listen on. default: 8807
• viewer.host: host address for the server to listen on. default: ::
• viewer.base: default base url for links that ssb-viewer can handle
• viewer.msg_base: base url for links to ssb messages
• viewer.feed_base: base url for links to ssb feeds
• viewer.blob_base: base url for links to ssb blobs
• viewer.img_base: base url for embedded blobs (images)
• viewer.emoji_base: base url for emoji images
• viewer.require_opt_in: whether to serve content from feeds that have not published a publicWebHosting about message. default: true
• viewer.disallowRobots: whether to direct search engines to not index the site. default: true
