njs-0.8.1

[Dmitry Volyntsev]

Hello,

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

Notable new features:
- Periodic code execution:
js_periodic direcrive specifies a content handler to run at regular 
interval.
The handler receives a session object as its first argument, it also has 
access
to global objects such as ngx.

: example.conf:
:  location @periodics {
:    # to be run at 1 minute intervals in worker process 0
:    js_periodic main.handler interval=60s;
:
:    # to be run at 1 minute intervals in all worker processes
:    js_periodic main.handler interval=60s worker_affinity=all;
:
:    # to be run at 1 minute intervals in worker processes 1 and 3
:    js_periodic main.handler interval=60s worker_affinity=0101;
:
:    resolver 10.0.0.1;
:    js_fetch_trusted_certificate /path/to/ISRG_Root_X1.pem;
:  }
:
: example.js:
:  async function handler(s) {
:    let reply = async ngx.fetch('https://nginx.org/en/docs/njs/');
:    let body = async reply.text();
:
:    ngx.log(ngx.INFO, body);
:  }
