Web3.js: `callbackify` from 'util' doesn't seem to be available in the browser

Created on 24 Sep 2020 · 5Comments · Source: ChainSafe/web3.js

When using Browserify 16.5.2, here's what I get from require('util'), as logged by console.log:
```
_extend: function _extend(origin, add)
debuglog: function debuglog(set)
deprecate: function deprecate(fn, msg)
format: function format(f)
inherits: function inherits(ctor, superCtor)
inspect: function inspect(obj, opts)
isArray: function isArray(ar)
isBoolean: function isBoolean(arg)
isBuffer: function isBuffer(arg)
isDate: function isDate(d)
isError: function isError(e)
isFunction: function isFunction(arg)
isNull: function isNull(arg)
isNullOrUndefined: function isNullOrUndefined(arg)
isNumber: function isNumber(arg)
isObject: function isObject(arg)
isPrimitive: function isPrimitive(arg)
isRegExp: function isRegExp(re)
isString: function isString(arg)
isSymbol: function isSymbol(arg)
isUndefined: function isUndefined(arg)
log: function log()
: Object { … }


`callbackify` is not available. Yet, `web3` attempts to use it here:

https://github.com/ethereum/web3.js/blob/866cb9917474e6618851960000db26e118589cd6/packages/web3-core-requestmanager/src/index.js#L23

This produces an error wen I try to use `web3` 1.3.0 in the browser:

Uncaught (in promise) TypeError: callbackify is not a function
send index.js:139
sendRequest index.js:609
send index.js:636
get_account eth.js:92
get_account eth.js:91
ensure_enabled eth.js:66
main main.js:458
async*[12]< main.js:614
o _prelude.js:1
r _prelude.js:1
_prelude.js:1
```

Please revise web3 to avoid the use of callbackify, or adjust it to source the function in a way that works with browserify.

you could bump the dependency for utli in a local build to 0.12 or downgrade web3 as suggested
