[nginx-announce] njs-0.4.0

[Dmitry Volyntsev]

Hello,

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

This release focuses on extending http and stream modules.

Notable new features:
- js_import directive.
: nginx.conf:
:   js_import foo.js;
:   js_import lib from path/file.js;
: 
:   location / {
:       js_content foo.bar;
:   }
:
: foo.js:
:   function bar(r) {
:       r.return(200);
:   }
:
:   export default {bar};

- multi-value headers support in r.headersOut:
: foo.js:
:   function content(r) {
:        r.headersOut[‘Set-Cookie’] = [
:               ‘foo=111; Max-Age=3600; path=/’,
:               ‘bar=qqq; Max-Age=86400; path=/’
:        ];
:        
:        r.return(200);
:   }
