Encode String to Base64 using Delphi in TMS Web Core

Question

In FMX, I could use the System.NetEncoding unit for encoding and decoding Base64 Strings in Delphi, but this unit doesn't seem to be available in TMS Web Core:

[Error] uMain_web.pas(29): can't find unit "System.NetEncoding"

What is the TMS Web Core alternative for System.NetEncoding or for decoding/encoding Base64?

Answer 1

Unfortunately, System.NetEncoding isn't available for TMS Web Core.

In TMS Web Core, you can use window.btoa() and window.atob() though. btoa encodes and atob decodes.

var
  EncodedString: String;
  DecodedString: String;
begin
  EncodedString := window.btoa('Shaun Roselt'); // Encode String to Base64
  DecodedString := window.atob('U2hhdW4gUm9zZWx0'); // Decode Base64 String
end;
