[nginx-announce] njs-0.4.1

[Dmitry Volyntsev]

Hello,

I'm glad to announce a new release of NGINX JavaScript module (njs).

This release extends http module.

Notable new features:
- raw headers API:
With the following request headers:
: Host: localhost
: Foo: bar
: foo: bar2
All 'foo' headers can be collected with the syntax:
: r.rawHeadersIn.filter(v=>v[0].toLowerCase() == 'foo').map(v=>v[1]);
the output will be:
: ['bar', 'bar2']

- TypeScript API definition:
: foo.ts:
: /// <reference path="ngx_http_js_module.d.ts" />
: function content_handler(r: NginxHTTPRequest) 
: {
:        r.headersOut['content-type'] = 'text/plain';
:        r.return(200, "Hello from TypeScript");
: }
: 
: tsc foo.ts --outFile foo.js
foo.js can be used directly with njs.
