js-translation.json generation incomplete

[AlexandreKhayrullin]

Preconditions

The Magento used is the "develop" branch.
PHP: PHP 7.0.10-1+deb.sury.org~xenial+1

Steps to reproduce

1. Install a locale pack on Magento (in this case, the locale is es_ES)
2. Set Magento in production mode.
3. Display a UiComponent on frontend using the installed locale

Expected result

1. The texts on the UiComponent are correctly translated

Actual result

1. The texts remain in English (or, rather, use the translation keys)

It seems that the generation of js-translation.json is inconsistent between developer and production modes.
In production mode, the JSON either contains very few values (see js-translation.production.json in the attached ZIP file) or just an empty array. In developer mode, the JSON contains a lot more strings (see js-translation.developer.json in the attached ZIP file) , enough to make the UiComponents translatable.

I have the same issue with ar-json - not always Arabic files are generated in the JSON.

We expect that updating the CSV file should also update the Knockout JS files and Magento translation but it does not - this include local storage translation API

Have the same issue with a clean Magento 2 install with a valid language pack. It's missing a lot of translations.

I've tested and problem persists also in Version 2.1.6

I found the problem mostly in Checkout

[PascalBrouwers]

Same problem here. I used the workaround explained here: #2056 (comment)

[Tristan-N]

Also having trouble with this situation. Especially with the "Place order now" button. Can't get it translated. Not using CSV, not using complete language packs and inline translation doesn't work either.

[PascalBrouwers]

I just had it in developer mode too. This happens so often now that I remove the js-translation.json and run setup:static-content:deploy for my local language every time a translation doesn't work.

[cjohansson]

We have created a work-around with a custom script which converts all .csv files to js-translation.json files and then manually rewrite requests to js-translation.json in our web-server to our custom files and it works everytime.

[Tristan-N]

@PascalBrouwers Thank you for the information, but that didn't work for me either. It's both in dev mode and in prod mode. I am wondering; does this issue occur in the checkout too? For me it's only in the checkout. Do you use a custom OneStepCheckout by for example Hungersoft or Magestore?

[PascalBrouwers]

We do have Magestore OSC, but it doesn't matter where the translation is when the entire js-translation.json file is empty :)

[Tristan-N]

Ah, i found out that the translations in our Magestore OSC broke because of $t('string') weren't the same as the data-bind in the span. I solved it by matching the data-binds (see screenshot). Maybe it might help you too.

Same issue here, $t translations work fine in developer mode, but fails in production mode

[Khaleel]

@cjohansson please can you share this solution of making a custom json file as I was considering doing the same. I would really appreciate it - is it a module or snippet that you can opensource?

[shanavas786]

rm pub/static/<area>/<vendor>/<theme>/<lang>/js-translation.json
setup:static-content:deploy <lang> --theme=<vendor>/<theme>

generated proper js-translation.json for <lang>, and translations work fine.

Any update on this issue?

[LiamKarlMitchell]

A problem in 2.3 it seems.
