how to publish data in mqtt browerify code in at browser side

[shenhome]

const cmd = Buffer.alloc(32); cmd[0] = 0xA2; cmd[1] = 0x01; client.publish('topic, cmd);

Above code is ok when at node.js server. But it's not ok when doing the same thing at browser side. I tried to change buffer.alloc to new ArrayBuffer(32). It's also failed.

So how to make binary data exchange between browser and device?

weapp side:

import mybuffer from '../xx/xx/mybuffer'

const buf = mybuffer.Buffer.from([0xA2,0x01])

client.publish('topic, buf);

browser side:

<script src="./mybuffer.js"/>

const buf = mybuffer.Buffer.from([0xA2,0x01])

client.publish('topic, buf);

mybuffer.js generated with browserify

bracket-notation.js :

var BrowserBuffer = require('../').Buffer

module.exports.Buffer = BrowserBuffer

package.json:

"perf": "browserify perf/bracket-notation.js -s mybuffer > perf/mybuffer.js && open perf/index.html",
