# Extract translation keys from code and maintain locale catalogs with i18next-parser

Use i18next-parser when an agent needs to scan a codebase, find translation calls, and update locale resource files as part of localization maintenance. This is a bounded catalog-maintenance workflow, not a generic i18n platform listing.

## Prerequisites

Node.js, source code using i18next translation patterns

## Installation

Use the upstream install or setup path that matches your environment:
- This project is no more maintained as of September 2025. Please use [i18next/i18next-cli](https://github.com/i18next/i18next-cli) instead that does everything you might need and more. Just run npx i18next-cli migrate-...
- yarn global add i18next-parser
- npm install -g i18next-parser
- yarn add -D i18next-parser

Requirements and caveats from upstream:
- 9.x is tested on Node 18, 20 and 22.
- 8.x is tested on Node 16, 18 and 20.
- 7.x is tested on Node 14, 16 and 18.

Basic usage or getting-started notes:
- ### CLI
- You can use the CLI with the package installed locally but if you want to use it from anywhere, you better install it globally:
- i18next 'app/**/*.{js,hbs}' 'lib/**/*.{js,hbs}' [-oc]
