About

Kore (https://kore.io) is an easy to use web application framework for writing scalable web APIs in C. Its main goals are security, scalability and allowing rapid development and deployment of such APIs.

Because of this Kore is an ideal candidate for building robust, scalable and secure web things.

Building Kore

Requirements

• openssl (latest is always the safest bet, right?) (note: this requirement drops away when building with NOTLS=1 NOHTTP=1)

Requirements for background tasks (optional)

• pthreads

Requirements for pgsql (optional)

• libpq

Normal compilation and installation:

# cd kore
# make
# make install

If you would like to build a specific flavor, you can enable those by setting a shell environment variable before running make.

• TASKS=1 (compiles in task support)
• PGSQL=1 (compiles in pgsql support)
• DEBUG=1 (enables use of -d for debug)
• NOTLS=1 (compiles Kore without TLS)
• NOHTTP=1 (compiles Kore without HTTP support)
• NOOPT=1 (disable compiler optimizations)

Example libraries

You can find example libraries under examples/.

The examples contain a README file with instructions on how to build or use them.

I apologize for unclear examples or documentation, I am working on improving those.
