Render in nodejs not working #231

Hi there,

This looks like a great i18n lib. I have some issues regarding a nodejs script. I need to parse a ejs template and I am trying to integrate this lib into the project.
This is how my code looks like.

var path = require('path');
var ejs = require('ejs');

var i18next = require("i18next");
var Backend = require("i18next-node-fs-backend");

var i18nextOptions = {
    debug: true,
    load: ['en'],
    preload: ['en'],
    fallbackLng: 'en',
    backend: {
        loadPath: path.join(__dirname,'/locales/{{lng}}/{{ns}}.json'),
        addPath: path.join(__dirname,'/locales/{{lng}}/{{ns}}.missing.json')
    },
    getAsync:false,
    postProcess: true,
    saveMissing: true,
    saveMissingTo: path.join(__dirname,'/locales/en/missing.json')
}

i18next.use(Backend).init(i18nextOptions, function (err, result) {
    return result
})

var t = function(key, count) {
    if(count) {
        return i18next.t(key, {count: count})
    }
    return i18next.t(key);
};

var tpl = ejs.renderFile(path.join(__dirname, '/views/index.ejs'), {t:t, title: 'Title', message: 'This is a message'})

console.log(tpl)

Instead of getting the translations, I get only the keys. I have tried to do this:
console.log(i18next.t('key'))
but with no success. It still prints the key and not the value.

this is the output:

'<!DOCTYPE html>
<html>
   <head>
      <title>test ejs with i18next </title>
   </head>
  <body>
      <div id="greeting">
            Title   This is a message  hello   You_message
       </div>
    </body>
</html>'

where hello is a key name and You_message is also a key name.

Any suggestions? Thanks in advance.

Best,
cojok

PS: I forgot to put in the output of the debugger:

i18next::translator: missingKey undefined translation hello hello
i18next::translator: missingKey undefined translation You_message You_message

--> undefined is the language

init with lng: 'en' and check if it works -> after that have a look in eg. i18next-express-middleware and the language detector plugin there

Checked with lng: 'en' and it gives back the same error.
I am not using expressjs at all. This nodejs script will be part of a lambda function. I will have a look on the i18next-express-middleware language detector.
Funny is that my code works inside an expressjs app.

Thanks.

In this case i guess - and should have be seen that before:

missing comes before backendConnector:loaded

You're calling t function before the async loading of those files are done -> move render into the i18next.init callback
