Specific Usage:

npm install -S nginx-conf Installation Tools

var NginxConfFile the require = ( 'Nginx-conf' ) .NginxConfFile;
 
// this api node provides the functionality to read and write files conf 
NginxConfFile.create ( '/etc/nginx.conf', function (ERR, conf) {
   IF (ERR ) { 
    the console.log (ERR); 
    return ; 
  } // read the value of each configuration by way _value

 
  the console.log (conf.nginx.user._value); // WWW WWW 
  the console.log (conf.nginx .http.server.listen._value); // one.example.com 

  // multiple submodules, modules, arranged in a plurality of such LOCATION server, accessible via the target array mode 
  console.log (conf.nginx.http .server.location [3] .root._value); // / spool / the WWW 

  // modify the configuration 
  create api // is synchronized to modify files for configuration changes and deletions be synced to disk

  Conf. on ( 'flushed', function () { 
    the console.log ( 'Writing to Disk Finished' ); 
  }); 

  // the listen to The flushed to the Determine When Event The new new Disk File has been flushed to 
  conf.nginx.events = 1000 .connections._value ; 

  // api this purpose is when the configuration changes are not written to disk 
  conf.die ( '/ etc / nginx.conf' ); 
  conf.nginx.events.connections._value = 2000; / / Change Remains local, Not in /etc/nginx.conf 

  // memory configuration file written to another 
  conf.live ( '/ etc / nginx.conf.bak' ); 

  // force the memory configuration brush disk 
  conf.flush (); 

  // add and remove instructions by _add and _remove
  conf.nginx.http._add('add_header', 'Cache-Control max-age=315360000, public');
  console.log(conf.nginx.http.add_header._value); //Cache-Control max-age=315360000, public

  conf.nginx.http._add('add_header', 'X-Load-Balancer lb-01');
  conf.nginx.http._add('add_header', 'X-Secure true');
  console.log(conf.nginx.http.add_header[0]._value); //Cache-Control max-age=315360000, public
  console.log(conf.nginx.http.add_header[1]._value); //X-Load-Balancer lb-01
  console.log(conf.nginx.http.add_header[2]._value); //X-Secure true

  conf.nginx.http._remove('the add_header'); // Removes the add_header [0] 
  conf.nginx.http._remove ( 'the add_header',. 1); // Removes the add_header [. 1] 

  // If only one command with a name, is to be expanded an attribute, table access by the array will be undefined 
  the console.log (conf.nginx.http.add_header._value); // X--the Load Balancer LB-01- 
  the console.log (conf.nginx.http.add_header [0 ]); // undefined 

  // Add a new module 
  conf.nginx.http._add ( 'Server' ); 
  conf.nginx.http.server._add ( 'the listen', '80' ); 

  // that'll something like the this Create: 
  / * 
    Server { 
      the listen 80; 
    } 
  * / 

  // multiple modules are accessed by way of an array
  conf.nginx.http._add('server');
  conf.nginx.http.server[1]._add('listen', '443');

  /*
    server {
      listen 80;
    }
    server {
      listen 443;
    }
  */

  // blocks with values:
  conf.nginx.http.server[1]._add('location', '/');
  conf.nginx.http.server[1].location._add('root', '/var/www/example.com');

  /*
    server {
      location / {
        root /var/www/example.com;
      }
    }
  */

  // lua blocks also work, but you can't put a mismatched "{" or "}" in a comment!
  conf.nginx.http.location._addVerbatimBlock('rewrite_by_lua_block', '{\n\
  ngx.say("this is a lua block!")\n\
  res = ngx.location.capture("/memc",\n\
    { args = { cmd = "incr", key = ngx.var.uri } }\n\
  )\n\
}');
});

 

This tool also supports changes to the comments

// read the annotations on the use configuration, so as to return the array 
the console.log (conf.nginx.events.use._comments.length); // . 1 
the console.log (conf.nginx.events.use._comments [0 ]); // use [kqueue | rtsig | epoll | / dev / poll | the SELECT | poll]; 

// Remove the comment 
conf.nginx.events.use._comments.splice (0, 1 ); 

// add comments 
conf. nginx.event.use._comments.push ( 'My new new Comment' ); 
the console.log (conf.nginx.events.use._comments.length); // . 1 
the console.log (conf.nginx.events.use._comments [0]); // My new new comment 

// Review Notes 
conf.nginx.event.use._comments [0] = 'Updated' ; 
the console.log (conf.nginx.events.use._comments [ 0]);//updated

Note the special circumstances

foo #comment
bar;

console.log(conf.nginx.foo._value); //bar
console.log(conf.nginx.foo._comments[0]); //comment
But if the comment comes after:

foo bar;
#comment
console.log(conf.nginx.foo._value); //bar
console.log(conf.nginx.foo._comments.length); //0
