[nginx-announce] njs-0.7.10

[Dmitry Volyntsev]

Hello,

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

Notable new features:
- Fetch API extended support, including Headers() and Request()
     constructors:
: async function makeRequest(uri, headers) {
:     let h = new Headers(headers);
:     h.delete("bar");
:     h.append("foo", "xxx");
:     let r = new Request(uri, {headers: h});
:     return await ngx.fetch(r);
: }

- Extended WebCrypto API, most notably JWK support was added:
: async function importSigningJWK(jwk) {
:    return await crypto.subtle.importKey('jwk', jwk,
:                                         {name: "RSASSA-PKCS1-v1_5"},
:                                         true, ['sign']);
: }

- XML parsing module:
: const xml = require("xml");
: let data = `<note><to b="bar" a= "foo" 
 >Tove</to><from>Jani</from></note>`;
: let doc = xml.parse(data);
:
: console.log(doc.note.to.$text) /* 'Tove' */
: console.log(doc.note.to.$attr$b) /* 'bar' */
: console.log(doc.note.$tags[1].$text) /* 'Jani' */
