ssb-ws v6.2.3

ssb-ws

Creates a web server for ssb clients

It is used by ssb clients, in scuttle-shell which is required for Patchfox, and in web projects like secret-islands.

Peers can replicate over ws, if a pub exposes a ws address and this enables sbot peers running in a browser (WIP).

Since ssb-ws creates a web server, it also exposes an interface that allows plugins to expose things over http. Blobs and emoji are provided via this plugin too.

usage

sbot plugins.install ssb-ws

best configured via connections config

"connections": {
  "incoming": {
    "ws": [{
      "scope": ["public", "local", "device"],
      "port": 9000,
      "transform": "shs",
      "http": true // serve http, see ws.use(handler)
    }]
  }
}

you can have more than one ws server if desired. you can also disable hosting of http handlers by setting web:false on the config item, connections.incoming.ws[N].web = false

Api

noauth

given the flexibility of multiserver, you may want to run this with noauth config locally. However this is not recommended until ssb-ws prevents dns rebinding attacks and websocket connections from locally open websites.

If used with a secure transport, that authenticates the client "transport": "shs" then this is not a problem.

ws.use(handler) - http handlers

sometimes you need to do http, but if every plugin that did that created it's own servers there would be mass panic. But never fear, with ssb-ws, you can add http handlers as connect style middleware.

Here is an example sbot plugin that adds a single route: to output the current sbot address.

require('scuttlebot')
  .use(require('ssb-ws'))
  .use({
    name: 'test123',
    version: '1.0.0',
    init: function (sbot) {
      sbot.ws.use(function (req, res, next) {
        if(req.url == '/get-address')
          res.end(sbot.getAddress('device'))
        else next()
      })
    }
  })

http hosting on a particular multiserver address can be disabled using {http:false} in the incoming multiserver config.
