    Hello,

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

    This release proceeds to extend the coverage of ECMAScript
    specifications.

    Notable new features:
    - Promises API for "fs" module.
    : var fs = require('fs').promises;
    : fs.readFile('/file/path').then(data => r.return(200, data));

    - detached r.subrequest(): Running a subrequest in the log phase
    : nginx.conf:
    : ...
    : js_set $js_log js_log;
    : ...
    : log_format subrequest_log "...$js_log";
    : access_log /log/path.log subrequest_log;
    :
    : nginx.js:
    : function js_log(r) {
    : r.subrequest('/_log', {detached:true});
    : return '';
    : }
