secret-stack-decorators

TypeScript or Babel decorators that make it possible to write secret-stack plugins in OOP style

Usage

npm install --save secret-stack-decorators

Only supports secret-stack >=6.2.0

In your TypeScript or Babel codebase, import plugin and muxrpc:

import {plugin, muxrpc} from 'secret-stack-decorators';
 
@plugin('1.0.0' /* version */)
class myplugin /* name */ {
  constructor(ssb, config) {
    /* init */
  }
 
  // This method will not show in the resulting plugin object
  privateMethod(x, y) {
    // ...
  }
 
  @muxrpc('sync') /* manifest: `shout: 'sync'` */
  shout = messsage => {
    // ...
  }
 
  @muxrpc('duplex', {anonymous: 'allow'}) /* manifest and permissions */
  communicate() {
    // ...
  }
}
 
module.exports = myplugin;

Example

Before:

var plugin = {
  name: 'ebt',
  version: '1.0.0',
  manifest: {
    replicate: 'duplex',
    request: 'sync',
    block: 'sync',
    peerStatus: 'sync'
  },
  permissions: {
    anonymous: {allow: ['replicate']}
  },
  init: function (sbot, config) {
    // INITIALIZATION CODE
 
    return {
      replicate: function (opts) { /* ... */ },
      request: function (id, other) { /* ... */ },
      block: function (id) { /* ... */ },
      peerStatus: function (id) { /* ... */ },
    }
  }
}

After:

@plugin('1.0.0')
class ebt {
  constructor(sbot, config) {
    // INITIALIZATION CODE
  }
 
  @muxrpc('duplex', {anonymous: 'allow'})
  replicate(opts) { /* ... */ }
 
  @muxrpc('sync')
  request(id, other) { /* ... */ }
 
  @muxrpc('sync')
  block(id) { /* ... */ }
 
  @muxrpc('sync')
  peerStatus(id) { /* ... */ }
}

API

@plugin(version: string)

This decorator should be placed on a class that is meant to be a secret-stack plugin. The version argument should be a string expressing a SemVer version.

Important: the name of the class is used as a string to register the plugin. class foo will be transformed to api.foo. This is why the class's name is usually lowercase.

@muxrpc(manifestType: string, permission?: object)

The manifestType argument is a string, should have the value 'sync' or 'async' or 'source' or 'sink' or 'duplex'. The optional permission object should have the shape {role: 'allow' | 'deny'}, i.e., the object's keys are names of roles (such as anonymous or master, etc), and the value can be either the string 'allow' or the string 'deny'.
