# TL;DR

Use GNU gettext format and i18next flow.

# Iteration

$ brew install gettext # convert .pot to .po
$ npm install -g i18next-conv # convert .po to .json

Edit index.html
Add data-i18n attribute
This is msgid
(Caution: Remove period from msgid!)

Add msgid + msgstr to _build/translation.pot

$ msgmerge -U _build/translation.en.po _build/translation.pot
$ msgmerge -U _build/translation.ja.po _build/translation.pot

Translate *.po

$ i18next-conv -l ja -s ./_build/translation.ja.po -t ./locales/ja/translation.json
$ i18next-conv -l en -s ./_build/translation.en.po -t ./locales/en/translation.json

Done!
