Crow supports Zlib compression using Gzip or Deflate algorithms.
HTTP compression is by default disabled in crow. Do the following to enable it:
CROW_ENABLE_COMPRESSION in your compiler definitions (
g++ main.cpp -DCROW_ENABLE_COMPRESSION for example) or
set(CROW_FEATURES compression) in
use_compression(crow::compression::algorithm) on your Crow app.
- When compiling your application, make sure that ZLIB is included as a dependency. Either through
-lz compiler argument or
find_package(ZLIB) in CMake.
3rd point is not needed for MSVC or CMake projects using
vcpkg.json and Crow's target already include zlib as a dependency.
For the compression algorithm you can use
And now your HTTP responses will be compressed.
Crow currently does not support Websocket compression.
Feel free to discuss the subject with us on GitHub if you're feeling adventurous and want to try to implement it. We appreciate all the help.
