reactifex

reactifex

Helper utility designed to make it easy to upload react-intl extracted messages to transifex, with support for ICU plurals and translator comments.

There are two modes of usage - compilation and comment pushing.

Compilation mode

In this mode, messages that have been extracted by babel-plugin-react-intl (into individual files) are combined. The resulting json is suitable to upload to Transifex and matches their specified KEYVALUEJSON format.

usage: $(npm bin)/reactifex <input_folder> <output_file>

• input_folder corresponds to the messagesDir option used by babel-plugin-react-intl
  • note that reactifex assumes folder structure based on this default
• output_file will be suitable for upload to transifex

Comment pushing

This mode is why I wrote this library in the first place - I wanted the ability to use comments as PO files do, but none of the tools I found to convert react-intl messages to PO files were able to properly handle ICU pluralization. By keeping everything in a js context with KEYVALUEJSON, plurals work correctly and we now have comment support for translators (by default, Transifex's KEYVALUEJSON file format does not allow for comments to be included with strings for translation).

Note that tests for this mode aren't included, as it relies on Transifex's API being up and responsive.

Usage is a little complicated, I'm sorry about that; you're going to be running this server-side as a series of bash commands. Do note that I assume $SECRET_USER and $SECRET_PWD env vars exist for basic auth purposes. See Transifex's API Introduction for more details on authentication. Here's an example, written as it would be in the Makefile of a project that makes use of reactifex:

tx_url1 = https://www.transifex.com/api/2/project/<project>/resource/<resource>/translation/<default_language_code>/strings/
tx_url2 = https://www.transifex.com/api/2/project/<project>/resource/<resource>/source/
push_translations:
    ./node_modules/reactifex/bash_scripts/get_hashed_strings.sh $(tx_url1)
    $$(npm bin)/reactifex <input_folder> --comments
    ./node_modules/reactifex/bash_scripts/put_comments.sh $(tx_url2)

• tx_url1 and tx_url2 are just variables as defined by the Transifex API documentation, extracted for readability.

• First, bash_scripts/get_hashed_strings.sh is called with a url argument. This will populate bash_scripts/hashmap.json with data about the strings in your resource, including the all-important string_hash.

• Next, the main reactifex script (node js) runs with an additional --comments flag, and no output file. This has the effect of gathering up all your babel-plugin-react-intl extracted messages with their comments attached. From there, it's simple enough to match up each message with its string_hash, and makes it possible to generate bash_scripts/put_comments.sh (a series of curl requests, one per message)

• Finally, bash_scripts/put_comments.sh is run with the base PUT url as an argument (we generated the specific string_hash portion in the previous step), updating translator comments for each message on Transifex via their API.
