converting buffer to string

Question

This is my data:

"buffer": {
        "type": "Buffer",
        "data": [
            8,
            4,
            18,
            32,
            203,
            243,
            203,
            190,
            254,
            80,
            185,
            227,
            225,
            187,
            114,
            219,
            243,
            87,
            83,
            254,
            248,
            95,
            139,
            1,
            26,
            198,
            149,
            158,
            30,
            44,
            146,
            237,
            166,
            70,
            199,
            9,
            26,
            32,
            138,
            251,
            102,
            14,
            230,
            244,
            102,
            250,
            142,
            53,
            210,
            190,
            9,
            23,
            169,
            98,
            14,
            156,
            148,
            99,
            168,
            204,
            145,
            108,
            191,
            223,
            189,
            58,
            202,
            61,
            52,
            254
        ]
    },

I want to convert it to a string. So far tried below mentioned things:

.toString()
.new String(buffer)
String.fromCharCode.apply(null, buffer)
buffer.map(c => String.fromCharCode(c)).join('') etc

Btw I have no access to data since when I try to access data it throws undefined so I pass the complete object which in this case is buffer to parse which is not returning the proper result. It is returning "\b Ì jQßô\f:l{Ê3DZz²ú_¿;t_ ¹ÐÇævËçÕ§MAjHríþ;!/Ýdãi",

Can someone help me with what it is that I am doing wrong?

which is not returning the proper result. So what is the proper result? Those numbers don't look like they'd result in readable ascii. — tkausl

@TienDuong I get the buffer as part of the response from fabric node js sdk when I call of its function. — prisoner_of_azkaban

There's no specific code as such. Its just a function call. let response = await channel.queryInfo(peer, true); Here's the function call if this helps — prisoner_of_azkaban

@tkausl yeah, I did not consider that possibility. It could be returning whatever i am getting right now. — prisoner_of_azkaban

You should pass the encoding to the .toString() function like in thew following example:

foo.toString('utf8');
