ruleeeer updated AVRO-3322:
---------------------------
Attachment: image-2022-01-25-15-57-43-468.png
Description:
When I use avro in my browser, I find that I get the `Buffer is undefined error`
Later I traced the source code and found that Buffer is used directly in
`/etc/browser/avro.js` and `/lib/schema.js`, which is not a problem in the node
environment because the Buffer object is mounted globally, but it is a problem
in the browser environment because using buffer polyfill will not mount the
Buffer object globally, You need to declare `var Buffer =
require('buffer').Buffer` manually, so that it can be used in the browser
environment without affecting the node environment, which also gets its Buffer
from require('buffer').
