Takes a particular sort of nested tree of methods and returns a version of that tree which has a scuttlebutt server injected into each method.

This pattern means you only need to inject a scuttlebot once, makes it easier to test your methods, and handles being able to inject different sorts of server for you.

Example usage

// methods.js
module.exports = {
  async: {
    publishPoll: function (server) {
      return function (opts, cb) {
        // check the opts before publishing
        const cleanOpts = clean(opts) 

        server.publish(cleanOpts, cb)
    // getPoll: (key, cb) => {}
  pull: {
    myPolls: function (server) {
      return function (opts) {
        const defaultQuery = { ... }
        const query = Object.assign({}, defaultQuery, opts)

    // openPolls: (opts) => {},
    // closedPolls: (opts) => {}

Injecting server once (somehwhere high-level):

const inject = require('scuttle-inject')
cosnt methods = require('./methods')

const scuttle = inject(methods, server)
// assume you're in a context where you have a server

Using the scuttle helper:

const opts = { ... }
scuttle.async.publishPoll(opts, cb)


inject(server, methods, pluginDeps)

  • server - a scuttlebot server, an ssb-client connection to a server, or an observeable which will resolve into a server connection (such as Patchcore's sbot.obs.connection)

  • methods - an Object nested at least 2 levels deep, where there must be one layer which specifies the type of method. Valid types are : sync, async, pull, obs

  • pluginDeps (optional) - an Array of plugins apis the scuttlebot must have for your methods to work. e.g. ['query'] will check that sbot.query has methods which are accessible.
