Code4bin Delphi | BEST ✧ |

Modern serverless platforms support custom runtimes. You can write a Delphi binary that reads from stdin or environment variables and writes JSON to stdout. Package this as a Lambda layer. The cold start time of a Code4Bin Delphi function is often under 10ms—significantly faster than Node.js or Python.

Let’s create a realistic Code4Bin.pas unit that you can drop into any Delphi project (10.3+ or modern Community Edition).

unit Code4Bin;
interface
uses
System.Classes, System.SysUtils;
type
TBinaryReaderHelper = class helper for TStream
private
function ReadByte: Byte; inline;
function ReadWord: Word; inline;
function ReadDWord: Cardinal; inline;
public
function ReadInt8: ShortInt;
function ReadUInt8: Byte;
function ReadInt32: Integer;
function ReadStringRaw(Length: Integer): string;
end; code4bin delphi
TBinaryWriterHelper = class helper for TStream
public
procedure WriteInt32(Value: Integer);
procedure WriteStringRaw(const Value: string);
end;
implementation
 TBinaryReaderHelper 
function TBinaryReaderHelper.ReadByte: Byte;
begin
Self.Read(Result, 1);
end; Modern serverless platforms support custom runtimes
function TBinaryReaderHelper.ReadInt32: Integer;
begin
Self.Read(Result, 4);
end;
function TBinaryReaderHelper.ReadStringRaw(Length: Integer): string;
var
Bytes: TBytes;
begin
SetLength(Bytes, Length);
Self.Read(Bytes[0], Length);
Result := TEncoding.ASCII.GetString(Bytes);
end;
 TBinaryWriterHelper 
procedure TBinaryWriterHelper.WriteInt32(Value: Integer);
begin
Self.Write(Value, 4);
end; This unit embodies the Code4Bin Delphi spirit: lightweight,
procedure TBinaryWriterHelper.WriteStringRaw(const Value: string);
var
Bytes: TBytes;
begin
Bytes := TEncoding.ASCII.GetBytes(Value);
Self.Write(Bytes[0], Length(Bytes));
end;
end.

This unit embodies the Code4Bin Delphi spirit: lightweight, type-safe, and directly mapped to binary I/O.

Before diving into the specifics of Code4Bin Delphi, it is essential to understand why a developer would choose Delphi for binary-first development in 2024.
