## Notice
There is a major breaking change since v1.0, and the API interface and options are not compatible with v0.x.
Checkout [Migration Guide](https://github.com/i18next/i18next-scanner/wiki/Migration-Guide) while upgrading from earlier versions.
## Features
* Fully compatible with [i18next](https://github.com/i18next/i18next) - a full-featured i18n javascript library for translating your webapplication.
* Support [react-i18next](https://github.com/i18next/react-i18next) for parsing the Trans component
* Support [Key Based Fallback](https://www.i18next.com/principles/fallback#key-fallback/) to write your code without the need to maintain i18n keys. This feature is available since [i18next@^2.1.0](https://github.com/i18next/i18next/blob/master/CHANGELOG.md#210)
* A standalone parser API
* A transform stream that works with both Gulp and Grunt task runner.
* Support custom transform and flush functions.
## Installation
```sh
npm install --save-dev i18next-scanner
```
or
```sh
npm install -g i18next-scanner
```
## Usage
### CLI Usage
```sh
$ i18next-scanner
Usage: i18next-scanner [options]
Options:
-V, --version output the version number
--config Path to the config file (default: i18next-scanner.config.js)
--output Path to the output directory (default: .)
-h, --help output usage information
Examples:
$ i18next-scanner --config i18next-scanner.config.js --output /path/to/output 'src/**/*.{js,jsx}'
$ i18next-scanner --config i18next-scanner.config.js 'src/**/*.{js,jsx}'
$ i18next-scanner '/path/to/src/app.js' '/path/to/assets/index.html'
```
Globbing patterns are supported for specifying file paths:
* `*` matches any number of characters, but not `/`
* `?` matches a single character, but not `/`
* `**` matches any number of characters, including `/`, as long as it's the only thing in a path part
* `{}` allows for a comma-separated list of "or" expressions
* `!` at the beginning of a pattern will negate the match
_Note: Globbing patterns should be wrapped in single quotes._

### Standard API
```js
const fs = require('fs');
const Parser = require('i18next-scanner').Parser;
const customHandler = function(key) {
parser.set(key, '__TRANSLATION__');
};
const parser = new Parser();
let content = '';
// Parse Translation Function
// i18next.t('key');
content = fs.readFileSync('/path/to/app.js', 'utf-8');
parser
.parseFuncFromString(content, customHandler) // pass a custom handler
.parseFuncFromString(content, { list: ['i18next.t']}) // override `func.list`
.parseFuncFromString(content, { list: ['i18next.t']}, customHandler)
.parseFuncFromString(content); // use default options and handler
// Parse Trans component
content = fs.readFileSync('/path/to/app.jsx', 'utf-8');
parser
.parseTransFromString(content, customHandler) // pass a custom handler
.parseTransFromString(content, { component: 'Trans', i18nKey: 'i18nKey', defaultsKey: 'defaults' })
.parseTransFromString(content, { fallbackKey: true }) // Uses defaultValue as the fallback key when the i18nKey attribute is missing
.parseTransFromString(content); // use default options and handler
// Parse HTML Attribute
//
content = fs.readFileSync('/path/to/index.html', 'utf-8');
parser
.parseAttrFromString(content, customHandler) // pass a custom handler
.parseAttrFromString(content, { list: ['data-i18n'] }) // override `attr.list`
.parseAttrFromString(content, { list: ['data-i18n'] }, customHandler)
.parseAttrFromString(content); // using default options and handler
console.log(parser.get());
console.log(parser.get({ sort: true }));
console.log(parser.get('translation:key', { lng: 'en'}));
```
### Transform Stream API
The main entry function of [i18next-scanner](https://github.com/i18next/i18next-scanner) is a transform stream. You can use [vinyl-fs](https://github.com/wearefractal/vinyl) to create a readable stream, pipe the stream through [i18next-scanner](https://github.com/i18next/i18next-scanner) to transform your code into an i18n resource object, and write to a destination folder.
Here is a simple example showing how that works:
```js
const scanner = require('i18next-scanner');
const vfs = require('vinyl-fs');
const sort = require('gulp-sort');
const options = {
// See options at https://github.com/i18next/i18next-scanner#options
};
vfs.src(['/path/to/src'])
.pipe(sort()) // Sort files in stream by path
.pipe(scanner(options))
.pipe(vfs.dest('/path/to/dest'));
```
Alternatively, you can get a transform stream by calling createStream() as show below:
```js
vfs.src(['/path/to/src'])
.pipe(sort()) // Sort files in stream by path
.pipe(scanner.createStream(options))
.pipe(vfs.dest('/path/to/dest'));
```
### Gulp
Now you are ready to set up a minimal configuration, and get started with Gulp. For example:
```js
const gulp = require('gulp');
const sort = require('gulp-sort');
const scanner = require('i18next-scanner');
gulp.task('i18next', function() {
return gulp.src(['src/**/*.{js,html}'])
.pipe(sort()) // Sort files in stream by path
.pipe(scanner({
lngs: ['en', 'de'], // supported languages
resource: {
// the source path is relative to current working directory
loadPath: 'assets/i18n/{{lng}}/{{ns}}.json',
// the destination path is relative to your `gulp.dest()` path
savePath: 'i18n/{{lng}}/{{ns}}.json'
}
}))
.pipe(gulp.dest('assets'));
});
```
### Grunt
Once you've finished the installation, add this line to your project's Gruntfile:
```js
grunt.loadNpmTasks('i18next-scanner');
```
In your project's Gruntfile, add a section named `i18next` to the data object passed into `grunt.initConfig()`, like so:
```js
grunt.initConfig({
i18next: {
dev: {
src: 'src/**/*.{js,html}',
dest: 'assets',
options: {
lngs: ['en', 'de'],
resource: {
loadPath: 'assets/i18n/{{lng}}/{{ns}}.json',
savePath: 'i18n/{{lng}}/{{ns}}.json'
}
}
}
}
});
```
## API
There are two ways to use i18next-scanner:
### Standard API
```js
const Parser = require('i18next-scanner').Parser;
const parser = new Parser(options);
const code = "i18next.t('key'); ...";
parser.parseFuncFromString(code);
const jsx = 'Default text';
parser.parseTransFromString(jsx);
const html = '
';
parser.parseAttrFromString(html);
parser.get();
```
#### parser.parseFuncFromString
Parse translation key from JS function
```js
parser.parseFuncFromString(content)
parser.parseFuncFromString(content, { list: ['_t'] });
parser.parseFuncFromString(content, function(key, options) {
options.defaultValue = key; // use key as the value
parser.set(key, options);
});
parser.parseFuncFromString(content, { list: ['_t'] }, function(key, options) {
parser.set(key, options); // use defaultValue
});
```
#### parser.parseTransFromString
Parse translation key from the [Trans component](https://github.com/i18next/react-i18next)
```js
parser.parseTransFromString(content);
parser.parseTransFromString(context, { component: 'Trans', i18nKey: 'i18nKey' });
// Uses defaultValue as the fallback key when the i18nKey attribute is missing
parser.parseTransFromString(content, { fallbackKey: true });
parser.parseTransFromString(content, {
fallbackKey: function(ns, value) {
// Returns a hash value as the fallback key
return sha1(value);
}
});
parser.parseTransFromString(content, function(key, options) {
options.defaultValue = key; // use key as the value
parser.set(key, options);
});
```
#### parser.parseAttrFromString
Parse translation key from HTML attribute
```js
parser.parseAttrFromString(content)
parser.parseAttrFromString(content, { list: ['data-i18n'] });
parser.parseAttrFromString(content, function(key) {
const defaultValue = key; // use key as the value
parser.set(key, defaultValue);
});
parser.parseAttrFromString(content, { list: ['data-i18n'] }, function(key) {
parser.set(key); // use defaultValue
});
```
#### parser.get
Get the value of a translation key or the whole i18n resource store
```js
// Returns the whole i18n resource store
parser.get();
// Returns the resource store with the top-level keys sorted by alphabetical order
parser.get({ sort: true });
// Returns a value in fallback language (@see options.fallbackLng) with namespace and key
parser.get('ns:key');
// Returns a value with namespace, key, and lng
parser.get('ns:key', { lng: 'en' });
```
#### parser.set
Set a translation key with an optional defaultValue to i18n resource store
```js
// Set a translation key
parser.set(key);
// Set a translation key with default value
parser.set(key, defaultValue);
// Set a translation key with default value using options
parser.set(key, {
defaultValue: defaultValue
});
```
### Transform Stream API
```js
const scanner = require('i18next-scanner');
scanner.createStream(options, customTransform /* optional */, customFlush /* optional */);
```
#### customTransform
The optional `customTransform` function is provided as the 2nd argument for the transform stream API. It must have the following signature: `function (file, encoding, done) {}`. A minimal implementation should call the `done()` function to indicate that the transformation is done, even if that transformation means discarding the file.
For example:
```js
const scanner = require('i18next-scanner');
const vfs = require('vinyl-fs');
const customTransform = function _transform(file, enc, done) {
const parser = this.parser;
const content = fs.readFileSync(file.path, enc);
// add your code
done();
};
vfs.src(['/path/to/src'])
.pipe(scanner(options, customTransform))
.pipe(vfs.dest('path/to/dest'));
```
To parse a translation key, call `parser.set(key, defaultValue)` to assign the key with an optional `defaultValue`.
For example:
```js
const customTransform = function _transform(file, enc, done) {
const parser = this.parser;
const content = fs.readFileSync(file.path, enc);
parser.parseFuncFromString(content, { list: ['i18n.t'] }, function(key) {
const defaultValue = '__L10N__';
parser.set(key, defaultValue);
});
done();
};
```
Alternatively, you may call `parser.set(defaultKey, value)` to assign the value with a default key. The `defaultKey` should be unique string and can never be `null`, `undefined`, or empty.
For example:
```js
const hash = require('sha1');
const customTransform = function _transform(file, enc, done) {
const parser = this.parser;
const content = fs.readFileSync(file.path, enc);
parser.parseFuncFromString(content, { list: ['i18n._'] }, function(key) {
const value = key;
const defaultKey = hash(value);
parser.set(defaultKey, value);
});
done();
};
```
#### customFlush
The optional `customFlush` function is provided as the last argument for the transform stream API, it is called just prior to the stream ending. You can implement your `customFlush` function to override the default `flush` function. When everything's done, call the `done()` function to indicate the stream is finished.
For example:
```js
const scanner = require('i18next-scanner');
const vfs = require('vinyl-fs');
const customFlush = function _flush(done) {
const parser = this.parser;
const resStore = parser.getResourceStore();
// loop over the resStore
Object.keys(resStore).forEach(function(lng) {
const namespaces = resStore[lng];
Object.keys(namespaces).forEach(function(ns) {
const obj = namespaces[ns];
// add your code
});
});
done();
};
vfs.src(['/path/to/src'])
.pipe(scanner(options, customTransform, customFlush))
.pipe(vfs.dest('/path/to/dest'));
```

Example Usage:
```
transform: function customTransform(file, enc, done) {
'use strict';
const parser = this.parser;
const contexts = {
compact: ['compact'],
max: ['Max'],
};
const keys = {
difficulty: { list: ['Normal', 'Hard'] },
minMax: { list: ['Min', 'Max'] },
};
const content = fs.readFileSync(file.path, enc);
parser.parseFuncFromString(content, { list: ['i18next.t', 'i18n.t'] }, (key, options) => {
// Add context based on metadata
if (options.metadata?.context) {
delete options.context;
const context = contexts[options.metadata?.context];
parser.set(key, options);
for (let i = 0; i < context?.length; i++) {
parser.set(`${key}${parser.options.contextSeparator}${context[i]}`, options);
}
}
// Add keys based on metadata (dynamic or otherwise)
if (options.metadata?.keys) {
const list = keys[options.metadata?.keys].list;
for (let i = 0; i < list?.length; i++) {
parser.set(`${key}${list[i]}`, options);
}
}
// Add all other non-metadata related keys
if (!options.metadata) {
parser.set(key, options);
}
});
done();
```
