详细介绍
facil.io is a C micro-framework for web applications. facil.io includes:
- A fast HTTP/1.1 and Websocket static file + application server.
- Support for custom network protocols for both server and client connections.
- Dynamic types designed with web applications in mind (Strings, Hashes, Arrays etc').
- Performant JSON parsing and formatting for easy network communication.
- A pub/sub process cluster engine for local and Websocket pub/sub.
- Optional connectivity with Redis.
facil.io provides high performance TCP/IP network services to Linux / BSD (and macOS) by using an evented design (as well as thread pool and forking support) and provides an easy solution to the C10K problem.
You can read more about facil.io on the facil.io website.
Important to Note
The master branch on the git
repo is the development branch and is likely to be broken at any given time (especially when working on major revisions, as I am at the moment).
Please select a release version for any production needs.
facil.io
Who's running on -
Iodine, a Ruby HTTP/Websockets Ruby application server is powered by
facil.io
- so everyone using the iodine server is running on facil.io. -
Are you using
facil.io
? Let me know!
An HTTP example
#include "http.h" /* the HTTP facil.io extension */
// We'll use this callback in `http_listen`, to handles HTTP requests
void on_request(http_s *request);
// These will contain pre-allocated values that we will use often
FIOBJ HTTP_X_DATA;
// Listen to HTTP requests and start facil.io
int main(int argc, char const **argv) {
// allocating values we use often
HTTP_X_DATA = fiobj_str_new("X-Data", 6);
// listen on port 3000 and any available network binding (NULL == 0.0.0.0)
http_listen("3000", NULL, .on_request = on_request, .log = 1);
// start the server
facil_run(.threads = 1);
// deallocating the common values
fiobj_free(HTTP_X_DATA);
}
// Easy HTTP handling
void on_request(http_s *request) {
http_set_cookie(request, .name = "my_cookie", .name_len = 9, .value = "data",
.value_len = 4);
http_set_header(request, HTTP_HEADER_CONTENT_TYPE,
http_mimetype_find("txt", 3));
http_set_header(request, HTTP_X_DATA, fiobj_str_new("my data", 7));
http_send_body(request, "Hello World!\r\n", 14);
}
facil.io
in your project
Using It's possible to either start a new project with facil.io
or simply add it to an existing one. GNU make
is the default build system and CMake is also supported.
facil.io
should be C99 compatible.
facil.io
Starting a new project with To start a new project using the facil.io
framework, run the following command in the terminal (change appname
to whatever you want):
$ bash <(curl -s https://raw.githubusercontent.com/boazsegev/facil.io/master/scripts/new/app) appname
You can review the script here. In short, it will create a new folder, download a copy of the stable branch, add some demo boiler plate code and run make clean
(which is required to build the tmp
folder structure).
Next, edit the makefile
to remove any generic features you don't need, such as the DUMP_LIB
feature, the DEBUG
flag or the DISAMS
disassembler and start development.
Credit to @benjcal for suggesting the script.
Notice: The master branch is the development branch. Please select the latest release tag for the latest stable release version.
Adding facil.io to an existing project
facil.io is a source code library, so it's easy to copy the source code into an existing project and start using the library right away.
The make libdump
command will dump all the relevant files in a single folder called libdump
, and you can copy them all or divide them into header ands source files.
It's also possible to compile the facil.io library separately using the make lib
command.
facil.io
as a CMake submodule
Using facil.io also supports both git
and CMake submodules. Credit to @OwenDelahoy (PR#8).
First, add the repository as a submodule using git
:
git submodule add https://github.com/boazsegev/facil.io.git
Then add the following line the project's CMakeLists.txt
add_subdirectory(facil.io)
More Examples
The examples folder includes code examples for a telnet echo protocol, a Simple Hello World server, an example for Websocket pub/sub with (optional) Redis, etc'.

Forking, Contributing and all that Jazz
The contribution guide can be found here.
Sure, why not. If you can add Solaris or Windows support to evio
and sock
, that could mean facil
would become available for use on these platforms as well.
If you encounter any issues, open an issue (or, even better, a pull request with a fix) - that would be great :-)
Hit me up if you want to:
-
Write tests... I always need more tests...
-
Help me write HPACK / HTTP2 protocol support.
-
Help me design / write a generic HTTP routing helper library for the
http_s
struct. -
If you want to help me write a new SSL/TLS library or have an SSL/TLS solution we can fit into
facil
(as source code)... Note: SSL/TLS solutions should fit both client and server modes. -
If you want to help promote the library, that would be great as well. Perhaps publish benchmarks or share your story.
-
Writing documentation into the
facil.io
website would be great. I keep the source code documentation fairly updated, but the documentation should be copied to thedocs
folder to get the documentation website up and running.
