Phoenix.Socket.V2.BERTSerializer (phoenix_socket_bert v1.2.0)

A serializer for Phoenix.Socket that encodes messages using BERT (Binary ERlang Term)

Fallback to Phoenix.Socket.V2.JSONSerializer for decoding messages that are not BERT encoded

Usage

Set the :serializer option in your Phoenix.Socket configuration:

endpoint.ex

socket "/live", Phoenix.LiveView.Socket,
  longpoll: [connect_info: [session: @session_options]],
  websocket: [
    connect_info: [session: @session_options],
    serializer: [{Phoenix.Socket.V2.BERTSerializer, "~> 2.0.0"}]
  ]

socket "/socket", Phoenix.Socket,
  websocket: [
    serializer: [{Phoenix.Socket.V2.BERTSerializer, "~> 2.0.0"}]
  ]

Import the phoenix_socket_bert in your app.js and add decode option to the LiveSocket configuration:

app.js

import { decode } from 'phoenix_socket_bert'
import { LiveSocket } from 'phoenix_live_view'
import { Socket } from 'phoenix'

let csrfToken = document.querySelector('meta[name="csrf-token"]').getAttribute('content')
let liveSocket = new LiveSocket('/live', Socket, {
  decode: decode,
  longPollFallbackMs: 2500,
  params: { _csrf_token: csrfToken }
})

liveSocket.connect()

let socket = new Socket("/socket", { decode: decode, params: { token: csrfToken } })
socket.connect()
