1. Preparation

1. Run npm install.
2. For good measure, in the package.json, run this check:
   1. Look for occurrences of GETTEXT_DOMAIN=.
   2. Check that, after the "=" there is the current plugin's text domain (e.g. sitepress for wpml-core). If not, fix it.
3. Check that the .gitignore file of the project contains this line: /locale/jed/**/*.po.

Note that, since WPML-Core embeds Translation Management as a Composer plugin, in package.json, you must have two occurrences of GETTEXT_DOMAIN: one for Core and another for TM.

2. Generating or updating the POT files

Run npm run strings:update-pot.

This command will generate or update the POT files for each JS app in /locale/jed/pot.

You can send these files for translation.

3. Updating the translations

1. Save the completed translations in /locale/jed/po.
2. Run npm run strings:jed to generate the JED files in /locale/jed.
3. Test the translations.
4. Commit the changes.

4. Additional notes

When committing the changes, you should only commit the POT and JED files (respectively, ``/locale/jed/pot/.potand/locale/jed/.json`).
