scorper

scorper is a micro and elegant web framework written in Nim

Build upon chronos and serveral excellent projects.

scorper will self contain manageable dependencies source code as much as posibble for accelerating development.

Compile flags

const HttpRequestBufferSize* {.intdefine.} = 2.Kb
const HttpHeadersLength* {.intdefine.} = int(HttpRequestBufferSize / 32) 
# 32 is sizeof MofuHeader
const gzipMinLength* {.intdefine.} = 20

Todos

• Parse http request streamingly.
• Parse form streamingly and lazyly.
• Send file and attachement streamingly.
• Http Basic auth, Bearer auth , Digest auth(planed).
• Serve static files (env:StaticDir)
• Parse JSON lazyly.
• cookies module.
• Parse JSON streamingly.
• Better error control flow.
• CLI tool generate object oriented controller and routes.
• Auto render response respect client accepted content type.
• Chuncked file upload handle for large file.

Conclusion

qps almost ten thousands faster than jester with stdlib. it even thousand faster than asynchttpserver

Limitations

the mofuparser use SIMD which relys on cpu support SSE or AVX instructions
