    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.

    You can learn more about njs:
