Ngx-extract-i18n-merge-json NPM

Angular JSON extract i18n and merge

Based on ngx-extract-i18n-merge by @daniel-sc.

This extends Angular CLI to improve the i18n extraction and merge workflow. New/removed translations are added/removed from the target translation files. Additionally, translation files are normalized (pretty print, sorted by id) so that diffs are easy to read (and translations in PRs might actually get reviewed ;-) ).

Install

Prerequisites: i18n setup with defined target locales in angular.json - as documented here.

ng add ngx-extract-i18n-merge-json

Usage

ng extract-i18n # this replaces and extends the original builder

Configuration

In your angular.json the target extract-i18n that can be configured with the following options:

Name	Default	Description
`browserTarget`	Inferred from current setup by `ng add`	A browser builder target to extract i18n messages in the format of `project:target[:configuration]`. See https://angular.io/cli/extract-i18n#options
`outputPath`	Inferred from current setup by `ng add`	Path to folder containing all (source and target) translation files.
`targetFiles`	Inferred from current setup by `ng add`	Filenames (relative to `outputPath` of all target translation files (e.g. `{"fr-FR": "messages.fr.json", "de-DE": "messages.de.json"`).
`sourceLocale`	Undefined	If this is set (to one of the `targetFiles` locales), new translations in that target file won't include the `newPrefix` prefix).
`sourceFile`	`messages.json`. `ng add` tries to infer non default setups.	Filename (relative to `outputPath` of source translation file (e.g. `"translations-source.json"`).
`newPrefix`	This prefix will be added to all new translations (e.g. `@new`).
`removeIdsWithPrefix`	`[]`	List of prefix strings. All translation units with matching `id` attribute are removed. Useful for excluding duplicate library translations.
`collapseWhitespace`	`true`	Collapsing of multiple whitespaces/line breaks in translation sources and targets.
`trim`	`false`	Trim translation sources and targets.
`includeContext`	`false`	Whether to include the context information (like notes) in the translation files. This is useful for sending the target translation files to translation agencies/services. When `sourceFileOnly` the context is retained only in the `sourceFile`.
`newTranslationTargetsBlank`	`false`	When `false` (default) the "target" of new translation units is set to the "source" value. When `true`, an empty string is used. When `'omit'`, no target element is created.
`builderI18n`	`"@angular-devkit/build-angular:extract-i18n"`	The builder to use for i18n extraction. Any custom builder should handle the same options as the default angular builder (browserTarget, outputPath, outFile, format, progress).
`verbose`	`false`	Extended/debug output - it is recommended to use this only for manual debugging.
