as-buffers
as-buffers
provides some Buffer types for reading/writing string/bytes efficiently and simply.
Usage
There are 2 useful buffer classes here: BytesBuffer
and StringBuffer
.
BytesBuffer
provides bytes related/endian related methods.StringBuffer
(is forked from MaxGraey) provides string (UTF16) related methods.
Write/Read bytes
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);
Write/Read string
let buf = new StringBuffer();
buf.write("hello");
expect(buf.toString()).toBe("hello");
More usages
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.
See unit tests and source comments.
