Restify async JSON body parser

When using server.use(restify.bodyParser(), content is buffered being passed through to JSON.parse().

With very large JSON, this quickly becomes a bottleneck, hanging restify thread while parsing JSON.

This library parses application/json requests asynchronously to avoid blocking the main event loop. All other requests are left unchanged.

Request below a certain size are also sent to the default bodyParser for performance.

Usage

var restifyAsyncJsonBodyParser = require('restify-async-json-body-parser');

server.use(restifyAsyncJsonBodyParser());

As for any restify middleware, you can pass options. Those options will get forwarded to the default bodyParser if used.

In addition to those options, you may use minLength to set a default size (in bytes) before switching to asynchronous. Default is 2500.
