Prerequisites
Your app must be prepared for localization.
You'll need an existing Lokalise project. Specifically, you'll require the project ID that can be found in the project settings.
A read/write Lokalise API token is required. Learn how to work with the API tokens in the corresponding article.
The Lokalise CLI tool must be installed.
In order to run the Lokalise CLI tool from grunt, you will need to set up the grunt-exec package.
Uploading to Lokalise
$ lokalise2 \
--token <token> \
--project-id <project_id> \
file upload \
--file "myapp/locale/en/\*.json" \
--lang-iso en
Downloading from Lokalise
When the translations are done, you'll need to download the language files from Lokalise:
$ lokalise2 \
--token <token> \
--project-id <project_id> \
file download \
--format json \
--original-filenames=true \
--unzip-to "myapp/locale/"
Run a similar command for all other project languages.
