Buffer.concat undefined is not a function

[kkartunov]

Hi,

in node doing Buffer.concat(...) of array of Buffers works but in the browser I get Buffer.concat undefined is not a function.

The code is like this:

...
var bodyArr = []
bodyArr.push(new Buffer('bla bla'));
bodyArr.push(new Buffer('bla2 bla2'));

var body = Buffer.concat(bodyArr);
...
req.write(body);
req.end();

I use this to create a POST body for http.
What could be the reason of this error?
I did checked that Buffer constructor is present after browserify build. But it looks that .concat method is not?

Works for me. What version of browserify are you using?

[kkartunov]

6.3.2 the latest i think

Investigating deeper it looks that Buffer.concat() is defined indeed.
Sorry for misleading!
Dumping the array that needs to be concated I see one string item inside and multiple Uint8Array items. Could it be that the string breaks the code?

[feross]

Yeah, Buffer.concat takes only an array of Buffer objects, as defined by node.js. First convert the string to a Buffer and you'll be all good :)

Sure :) , thanks!
