Extract translatable (ngx-translate) strings and save as a JSON or Gettext pot file. Merges with existing strings if the output file already exists.


Install the package in your project: npm install @biesbjerg/ngx-translate-extract --save-dev Add an extract script to your project's package.json: ``` "scripts": { "extract": "ngx-translate-extract --input ./src --output ./src/assets/i18n/.json --clean --sort --format namespaced-json" } ``` You can now run npm run extract to extract strings.

Extract examples

Extract from dir and save to file ngx-translate-extract -i ./src -o ./src/i18n/strings.json Extract from multiple dirs ngx-translate-extract -i ./src/folder-a ./src/folder-b -o ./src/i18n/strings.json Extract and save to multiple files ngx-translate-extract -i ./src -o ./src/i18n/{da,en,fr}.json or ngx-translate-extract -i ./src -o ./src/i18n/da.json ./src/i18n/en.json ./src/i18n/fr.json or (update only) ngx-translate-extract -i ./src -o ./src/i18n/*.json or (update only)

Custom indentation

By default, tabs are used for indentation when writing extracted strings to json formats: ngx-translate-extract -i ./src -o ./src/i18n/en.json --format-indentation $'\t' If you want to use spaces instead, you can do the following: ngx-translate-extract -i ./src -o ./src/i18n/en.json --format-indentation ' '

Mark strings for extraction using a marker function

If, for some reason, you want to extract strings not passed directly to TranslateService, you can wrap them in a custom marker function. ```ts import { } from '@biesbjerg/ngx-translate-extract'; ('Extract me'); ``` Add the marker argument when running the extract script: ngx-translate-extract ... -m _ Modify the scripts arguments as required.
