The Lithium C++ Libraries

========================

Lithium's goal is to ease the development of C++ high performance HTTP APIs. As much effort is put into simplifying it's use as in optimizing its performances. According to the TechEmpower benchmark, it is one of the fastest web framework available.

It is a set of independent header only C++ libraries, each one of them can be used independently. Each library solves one problem and can be used separately.

A zero-cost compile time key/value map.

A JSON serializer/deserializer designed for ease of use and performances.

A set of tools to interact with SQL databases.

A http_client built around the libcurl library.

A library that eases the writing of web HTTP APIs.

The root of the lithium project. Used by all other libraries. You probably will not use this library directly but you can check the code if you want to know what is inside the s:: namespace.

You can either use the single header version of the libraries (does not provide the li_symbol_generator utility): https://github.com/matt-42/lithium/tree/master/single_headers

Or install the lithium project:

git clone https://github.com/matt-42/lithium.git
cd lithium;
mkdir build; cd build;
cmake .. -DCMAKE_INSTALL_PREFIX=_your_prefix_; make -j4 install;

- Linux: G++ 9.2, Clang++ 9.0
- Macos: Clang 11 (everything except http_backend that relies on epoll)
- Not supported anymore: Windows: MSVC 19
