Cant't resolve fs after updating to 13.0.3 version

[spirosdi]

I am using file-type in an angular app. When running ng serve, I get the following:
ERROR in ./node_modules/strtok3/lib/FsPromise.js
Module not found: Error: Can't resolve 'fs' in /node_modules/strtok3/lib'
With v12 it works

And you did include (require) 'file-type/browser' instead of 'file-type' as described here @spirosdi?

[spirosdi]

ah right.. missing fs is now resolved. But I get a console error:

Just by including file-type/browser

[Borewit]

Some of the Node modules need to be polyfilled to make file-type work in the browser.

Install process:

npm i process

In polyfill.ts add:

import * as process from 'process';
(window as any).process = process;

You may need to add buffer as well:

npm i buffer

In polyfill.ts add:

import * as _buffer from 'buffer';
(window as any).Buffer = _buffer.Buffer;

Example: audio-tag-analyzer/blob/master/src/polyfills.ts
