Basic client not working

[timmeade]

i converted the basic client to es6 as that is what we use. Also our FS servers are not on localhost and this is just seeming to not work. Any help or thoughts are appreciated.

// const FS = require('esl');

const fsCommand = (cmd) => {
  const client = FS.client(() => {
    this.api(cmd)
      .then((res) => {
        console.log(res);
        // res contains the headers and body of FreeSwitch's response.
        // res.body.should.match(/\+OK/);
      })
      .then(() => {
        console.log('exit');
        this.exit();
      })
      .then(() => {
        console.log('end');
        client.end();
      });
  });
  // console.log(client);
  client.connect(8021, '10.2.20.21');
};

fsCommand('reloadxml');

@timmeade There are plenty of reasons this could fail (connectivity issues between the client and FreeSwitch, password different from default, etc.); running your script with DEBUG="*" in the environment should help diagnose.

interesting. that helped. Says the 'api' property is undefined.

i tried hardcoding the command and got the same thing.

this.api('reloadxml')

Ah, using the => shortcut won't work because it binds this inside your function.

Try for example

const fsCommand = function (cmd) {

etc.

Made no difference. I am using babel to transpose this, so curious what that would change.

[shimaore]

That's strange. Did you replace all the occurrences of => with function ()?

Basically => works as (function () {…}).bind(this). In the example you provided this means this.api tries to locate .api in your global (topmost) context.
