I tried to port my Pyjs project to Brython recently, and it failed because Brython was terribly slow. Just loading library took more than 10 minutes and my web browser died due to memory problem in Brython. Beside speed, Brython seems to have a big problem in memory management. So, I had no choice but to coming back to Pyjs. I think that Brython may be good for a small-sized project, but not for a big project.
Pyjs has advantages compared to Brython as follows: 1. Pyjs compiles Python to Javascript offline. So, loading and execution speed is fast especially when source size is big. Brython converts Python source to Javascript during runtime. Theoretically, loading and compiling Python code is faster than loading compiled javascript code in the low speed Internet. But in reality, this conversion is very slow consuming a lot of memory when source size is big. 2. Python source code is not exposed to public The compiled Javascript by Pyjs is complicated enough to hide Python source. It is not perfect protection compared to compiled byte-code. But it is a lot better than most obfuscation software available for Python. If you use Brython, your source code is literally exposed to public. 3. Pyjs is designed to support MVC(Model-View-Controller) Thanks to MVC, You don't have to write HTML code and you can reuse existing module and class easily. Brython is designed mainly to replace Javascript, and you have to write html code undermining reusability and unreadability. 4. Pyjs has desktop solution Brython is a brwoser-only solution. On the other hand, Pyjs' desktop solution makes debugging easier though not perfect. I hope to see further improvement of Pyjs. Brython will not be able to replace Pyjs in the near future due to the fundamental differences listed above. Pyjs is the only solution for my project so far. 2016년 3월 1일 화요일 오후 7시 20분 54초 UTC+9, Adrien 님의 말: > > BTW Pyjamas is dead and pyjs is slowly dying.
