Installation

npm install wings4

or

yarn add wings4

Usage

import wings from 'wings4'
// const wings = require('wings4').default

let app = wings('http://localhost:3030')

let messagesSrvc = app.wingsService('messages')

messagesSrvc.on('dataChange', (messages) => {
  console.log(messages)
})

messagesSrvc.init()

app.wingsService(serviceName, params, config)

Returns a wingsService <object>

params.query <object>

Refer to Feathers Querying

/* example records
  [
    { text: 'Hello', read: true, roomId: 1, nested: { prop: 'xander' } },
    { text: 'World', read: false, roomId: 2, nested: { prop: 'ford' } }
  ]
*/

let serviceName = 'message'

let params = {
  query: {
    read: false,
    roomId: 2
  }
}

let messagesSrvc = app.wingsService(serviceName, params)

messagesSrvc.on('dataChange', (messages) => {
  console.log(messages)
  // [ { text: 'World', read: false, roomId: 2, nested: { prop: 'ford' } } ]
})

config <object>

let config = {
  debug: true,
  newDataPosition: 'start',
  paginate: true,
  channels: []
} 

let messagesSrvc = app.wingsService(serviceName, params, config)

config.channels <array> and channel <object>

Channels determine which records to receive that passes the prop === value .

/* example records
  [
    { text: 'Hello', read: true, roomId: 1, nested: { prop: 'xander' } },
    { text: 'World', read: false, roomId: 2, nested: { prop: 'ford' } }
  ]
*/

let config = {
  channels: [
    { prop: 'roomId', value: 2},
    { prop: 'nested.prop', value: 'ford'},
    { prop: 'nested', value: (val) => val.prop === 'ford' }
  ]
}

let messagesSrvc = app.wingsService(serviceName, params, config)

You may use dot notation in prop as reference into the object's property

reset(params, config)

set new params, config and triggers init method

let params = {
  query: {
    read: false,
    roomId: 2
  }
}

let config = {
  debug: true,
  newDataPosition: 'start',
  paginate: true,
  channels: []
}

messagesSrvc.reset(params, config)

loadMore()

loads more data based on $skip = ( page + 1 ) * $limit

messagesSrvc.loadMore()

loadAll()

loads all data based on ($skip = page $limit) pages

messagesSrvc.loadAll()

loadPage(page)

loads the based on $skip = page * $limit

messagesSrvc.loadPage(2)

destroy()

messagesSrvc.destroy()

Single Sign-On (Backend)

npm install feathers-sso

or

yarn add feathers-sso

// authentication.js
const { LocalStrategy } = require('@feathersjs/authentication-local');
const { expressOauth } = require('@feathersjs/authentication-oauth');
const Sso = require('feathers-sso')

module.exports = app => {
  const authentication = new AuthenticationService(app);

  authentication.register('jwt', new JWTStrategy());
  authentication.register('local', new LocalStrategy());
  authentication.register('sso', new Sso('http://localhost:3030'));

  app.use('/authentication', authentication);
  app.configure(expressOauth());
};

Single Sign-On (Frontend)

enables SSO to specific iframe parent host

// SSO login UI
app.enableSSO([
  'http://localhost:8080',
