I am trying to modify the way ember-i18n localizations are loaded. What I want to do is have the localizations in a separate file from the main app javascript file.
Ideally, the structure would remain the same as now. So I would have app/locales/fr/translations.js
and app/locales/de/translations.js
, each having content similar to this:
export default {
key: "value"
}
So I thought I need to write a custom addon, which would alter the build process. This addon would need to:
Ignore
app/locales
from final buildCompile all the translation files into one
Transpile the new file with babel
Copy the file in
dist/assets/translations.js
The combined translation file would look something like this:
export default {
fr: {
key: "value"
},
de: {
key: "value"
}
This way, I would be able to use and instance initializer and simply import and use this module:
import Translations from 'my-translations';
export function initialize(instance) {
const i18n = instance.lookup('service:i18n');
for(let lang in Translations) {
if(Translations.hasOwnProperty(tag)) {
i18n.addTranslations(tag, Translations[tag]);
}
}
}
Also, index.html
would be:
<script src="assets/vendor.js"></script>
<script src="assets/translations.js"></script>
<script src="assets/my-app.js"></script>
Well, I started writing the custom addon, but I got stuck. I managed to ignore the locales, and I wrote code that parses all the localizations, but I do not know how to write the new translations file in dist
. What hook do I neeed to use, to be able to write into dist
? Any help? Thank you so much.
Here is the code I wrote:
Stuff I use
var Funnel = require('broccoli-funnel');
var stew = require('broccoli-stew');
var fs = require('fs');
var writeFile = require('broccoli-file-creator');
var mergeTrees = require('broccoli-merge-trees');
preprocessTree: function(type, tree) {
if(type !== 'js') {return tree;}
var treeWithoutLocales = new Funnel(tree, {
exclude: ['**/locales/*/translations.js']
});
var translations = {};
var files = fs.readdirSync('app/locales');
files.forEach((tag) => {
if(tag !== 'fr') {return;}
let contents = fs.readFileSync('app/locales/' + tag + '/translations.js', 'utf8');
contents = contents.replace(/^export default /, '');
contents = contents.replace(/;$/, '');
contents = JSON.parse(contents);
translations[tag] = contents;
});
// Should do something with this .. how to write in dist? and when? I need it compiled with babel
var fileTree = writeFile('/my-app/locales/translations.js', 'export default ' + JSON.stringify(translations) + ';');
return treeWithoutLocales;
}
I am not sure if you actually asked a question; but here goes some kind of answer. Why complicate? Just use James Rosen's i18n addon used by a lot of projects.
