buffer.readUIntLE()

buf.readUIntLE(offset, byteLength[, noAssert])

Reads byteLength number of bytes from the Buffer at the specified offset and interprets the result as an unsigned integer. Supports up to 48 bits of accuracy. For example:

const buf = Buffer.allocUnsafe(6);
buf.writeUInt16LE(0x90ab, 0);
buf.writeUInt32LE(0x12345678, 2);
buf.readUIntLE(0, 6).toString(16);  // Specify 6 bytes (48 bits)
// Returns: '1234567890ab'

buf.readUIntBE(0, 6).toString(16);
// Returns: ab9078563412

Setting noAssert to true skips validation of the offset. This allows the offset to be beyond the end of the Buffer.
