[nginx-announce] njs-0.7.0

[Dmitry Volyntsev]

Hello,

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

This release adds a bunch of long-awaited features.

Notable new features:
- async/await support:
- HTTPS support in Fetch API:
: async function content(r) {
:     let results = await Promise.all([ngx.fetch('https://nginx.org/'),
:                                      ngx.fetch('https://nginx.org/en/')]);
:
:     r.return(200, JSON.stringify(results, undefined, 4));
: }

- WebCrypto API support:
: async function host_hash(r) {
:     let hash = await crypto.subtle.digest('SHA-512', r.headersIn.host);
:     r.setReturnValue(Buffer.from(hash).toString('hex'));
: }
