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());

Options

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.
