Gettext Extractor

A flexible and powerful Gettext message extractor with support for JavaScript, TypeScript, JSX and HTML

It works by running your files through a parser and then uses the AST (Abstract Syntax Tree) to find and extract translatable strings from your source code. All extracted strings can then be saved as .pot file to act as template for translation files.

Unlike many of the alternatives, this library is highly configurable and is designed to work with most existing setups.

For the full documentation check out the Github Wiki.

Installation

Note: This package requires Node.js version 6 or higher.

Getting Started

Let's start with a code example:

const { GettextExtractor, JsExtractors, HtmlExtractors } = require('gettext-extractor');

let extractor = new GettextExtractor();

extractor
    .createJsParser([
        JsExtractors.callExpression('getText', {
            arguments: {
                text: 0,
                context: 1
            }
        }),
        JsExtractors.callExpression('getPlural', {
            arguments: {
                text: 1,
                textPlural: 2,
                context: 3
            }
        })
    ])
    .parseFilesGlob('./src/**/*.@(ts|js|tsx|jsx)');

extractor
    .createHtmlParser([
        HtmlExtractors.elementContent('translate, [translate]')
    ])
    .parseFilesGlob('./src/**/*.html');

extractor.savePotFile('./messages.pot');

extractor.printStats();

A detailed explanation of this code example and much more can be found in the Github Wiki.
