# FAQ
## Misc
### **i18next is awesome. How can I support the project?**
*There are a lot of ways to support us. Make a PR for a feature requested. Improve the documentation. Help others to get started. Spread the word.*
*You can support the future of i18next by using* [*Locize*](https://www.locize.com/?utm_source=i18next_com\&utm_medium=gitbook\&utm_campaign=how_to_faq)*. It’s our 'Localization as a Service' offering that funds the development of this open-source ecosystem. With our **Free plan**, you can now support the project even on smaller hobby sites at no cost, while benefiting from a professional translation workflow.*
## Loading issues
### **I don't see my translations!!!**
*Try setting* `debug: true` *on init and check the console log. There is rather sure a warning for unable to resolve the loadPath or invalid json. Check if the translation files are accessible via browser.*
## Translation
### **How to translate the resource files?**
For a quick and dirty machine translation you may have a look at [this free translator](https://translate.i18next.com).\
But in general we suggest to use a smart Translation Management Service like [locize](https://www.locize.com?utm_source=i18next_com\&utm_medium=gitbook\&utm_campaign=how_to_faq) to translate your i18next resources.
For professional translations we advice you to work with [human translators](https://www.locize.com/docs/guides/working-with-translators?utm_source=i18next_com\&utm_medium=gitbook\&utm_campaign=how_to_faq). Or at least proofread the results coming from machine translations.
### **How do i know which plural suffix i have to use?**
*On the* [*plural page*](/translation-function/plurals.md) *there is a tool to get them.*
*Or try* [*translation-check*](https://github.com/locize/translation-check)*, it shows an overview of your translations in a nice UI. It shows also the appropriate plural forms.*
*Or you use a smart translation management system, like* [*locize*](https://www.locize.com?utm_source=i18next_com\&utm_medium=gitbook\&utm_campaign=how_to_faq)*.*
### **Why are my plural keys not working?**
*Are you seeing this warning in the development console?*
> i18next::pluralResolver: Your environment seems not to be Intl API compatible, use an Intl.PluralRules polyfill. Will fallback to the compatibilityJSON v3 format handling.
*With v21 we* streamlined the suffix with the one used in the [Intl API](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/PluralRules/PluralRules).
*In environments where the* [*Intl.PluralRules*](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/PluralRules) *API is not available (like older Android devices), you may need to* [*polyfill*](https://github.com/eemeli/intl-pluralrules) *the* [*Intl.PluralRules*](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/PluralRules) *API.*\
\&#xNAN;*In case it is not available it will fallback to the* [*i18next JSON format v3*](/misc/json-format.md#i-18-next-json-v3) *plural handling. And if your json is already using the new suffixes, your plural keys will probably not be shown.*
*tldr;*
```shell
npm install intl-pluralrules
```
```javascript
import 'intl-pluralrules'
```
### How should the language codes be formatted?
*Theoretically, you're not bound to any specific language code format, but if you want to make use of all the in built language features, like proper* [*pluralization*](/translation-function/plurals.md) *and correct* [*fallback resolution*](/principles/fallback.md#language-fallback)*, we strongly suggest to use the following iso norm (BCP 47 language tag):*
`lng-(script)-REGION-(extensions)`\
\
\&#xNAN;*i.e.*
* *en, en-US or en-GB*
* *zh, zh-HK or zh-Hant-HK*
*Other examples are listed here:* [*https://www.iana.org/assignments/language-tags/language-tags.xhtml*](https://www.iana.org/assignments/language-tags/language-tags.xhtml)
*And more information about the format can be found here:* [*https://www.w3.org/International/articles/language-tags/*](https://www.w3.org/International/articles/language-tags/)
{% hint style="info" %}
As soon as you use the dash character `-` the language codes are tried to be formatted with `Intl.getCanonicalLocales`.
{% endhint %}
## Process
### **How do I keep overview over my translation progress?**
*Try* [*translation-check*](https://github.com/locize/translation-check)*, it shows an overview of your translations in a nice UI. Check which keys are not yet translated.*
*If you need more, it might be time to use a* [*translation management tool*](https://www.locize.com?utm_source=i18next_com\&utm_medium=gitbook\&utm_campaign=how_to_faq)*.*
### **How to handle with changes in e2e tests?**
*For e2e tests a good tactic is to set language to* `cimode` *on init. This will set i18next to always return the key on calling* `i18next.t`*. Want to add the namespace to returned value change* `appendNamespaceToCIMode: true` *on init.*
### **How to use i18next in serverless environments?**
Due to how serverless functions work, you cannot guarantee that a cached version of your data is available. Serverless functions are short-lived, and can shut down at any time, purging any in-memory or filesystem cache. This may be an acceptable trade-off, but sometimes it isn't acceptable.
Because of this we suggest to not use a remote backend and to download the translations and package them with your serverless function.
