Videur

======

Pronounced:  */vidœʀ/*

***experimental project***

Videur is a Lua library for OpenResty that will automatically parse

an API specification file provided by a web server and proxy incoming

Nginx requests to that server.

Videur takes care of rejecting requests that do not comply with the

specification definitions, such as:

- unknown GET arguments

- bad types or out of limits arguments

- missing authorization headers

- POST body too big

- too many requests per second on a given API

- etc..

To get a detailed list of rules that can be used,

look at the `Videur API Specification 0.1

document `_

Installation

------------

To install Videur, you need to have an OpenResty environment deployed.

Then you can run::

	make install

If you have a specific Lua lib directory, you can use the **LUA_LIB_DIR** and

**LUA_TREE** options.

This command will simply copy all the lua files of the Videur lib into

the OpenResty lib directory.

Usage

-----

Using Videur in Nginx is done in three directives.

First of all, you need to define a couple of Lua shared dicts:

- **cached_spec**, where Videur will store the API specification the backend provided

- **stats**, where Videur keeps track of the hits for its rate limiting feature

Then you need to set a **spec_url** variable with the URL of the API spec.

This URL should be a JSON document as defined in the `Videur API

Specification 0.1 document `_

Last, the **access_by_lua_file** directive needs to point to the

**dynamic_proxy_pass.lua** script from the Videur library.

Example::

    http {

        lua_shared_dict cached_spec 512k;

        lua_shared_dict stats 512k;

        server {

            listen 80;

            set $spec_url "http://127.0.0.1:8282/api-specs";

            access_by_lua_file "dynamic_proxy_pass.lua";

        }

    }
