Support for Hapi

[drewda]

Can i18n-node support the Hapi framework? If so, how about including an example?

I'm sure it will, as i18n is generally "framework agnostic". The examples provided show only a few of possible integrations.

In general i18n could get attached to any object, like so:

var anyObject = {
  __: i18n.__
};

i18n.configure({
  locales: ['en', 'de'],
  register: anyObject
});

anyObject.setLocale('en');
anyObject.__('Hallo'); // --> Hello

or, coul be used as middleware, by providing the common i18n.init(req, res) interface.

I am not familiar with hapi, but will take a look...

Thanks for your quick response and for the example code! On Aug 1, 2014 2:13 AM, "Marcus Spiegel" notifications@github.com wrote:

After fiddling around for some time i came up with this solution. So if anyone is interested here is the code. Basically it attaches the i18n interface to every view. Feedback welcome :)

var i18n = require('i18n'),
    extend = require('util')._extend;

exports.register = function(plugin, options, next) {

    // we need to check if a register object was defined,
    // since we have to attach it later to the request.response.source.context
    options.register = options.register || {};

    // Load settings and bind i18n interface to options.register
    i18n.configure(options);

    // Bind interface to global context
    // See: http://hapijs.com/tutorials/views#global-context
    plugin.ext('onPreResponse', function(request, reply) {
        var source = request.response.source;

        // Attach interface only if we got a view
        if (request.response.variety === 'view') {
            // Initialize i18n on request and response
            // Not quite sure if response is needed at all? Works fine without too
            i18n.init(request, request.response);
            // Use 'accept-language' header to guess language settings
            i18n.setLocale(i18n.getLocale(request));
            // Attach the interface to the view
            source.context = extend(source.context || {}, options.register);
        }

        reply();
    });

    next();
};

exports.register.attributes = {
    name: 'i18n'
};

thank you @davidspiess

note to myself: express hapi usage in examples
