as-buffers provides some Buffer types for reading/writing string/bytes efficiently and simply.
There are 2 useful buffer classes here:
BytesBufferprovides bytes related/endian related methods.
StringBuffer(is forked from MaxGraey) provides string (UTF16) related methods.
let buf = BytesBuffer.wrap(new ArrayBuffer(0)); let val = 0x11 as i8; buf.writeNumberBE<i8>(val); let res = buf.readNumberBE<i8>(0); expect(res).toBe(val);
let buf = new StringBuffer(); buf.write("hello"); expect(buf.toString()).toBe("hello");
In addition to some safe methods, they also have some unsafe methods to improve performance. You need to pay attention to the buffer capacity and read/write offset.
