How to read binary data from Buffer node.js as number?

Question

Currently I am receiving a message with my udp server it arrives as <Buffer 43 31 07 55 56> this is supposed to be an ID 4331075556

• obj.toString() returns C1UV
• parseInt(obj) returns NaN
• JSON.stringify(obj) returns [67,49,7,85,86]

How can I convert <Buffer 43 31 07 55 56> to 4331075556?

Answer 1

you need to specify an additional argument in toString():

obj.toString('hex')
