Element Translate

element-translate-ng is a translation abstraction layer. It can be used with

• ngx-translate
• Angular localize
• Other frameworks in the future

See here for details how it works and how to use it.

Usage

Install the library as follows:

npm install --save @siemens/element-translate-ng

An important part of the library is the extraction of translatable keys as a TypeScript interface as well as extracting a JSON messages file with default translations. The extraction happens on compiled files. I.e. make sure to run the build first. Then, to run these extractions

npx update-translatable-keys

By default, this will pick of the configuration from a file element-translate.conf.json. To use a different config file, pass as the only argument to the command.

The config file looks like this

{
  "files": "dist/@simpl/**/fesm2022/**/*.mjs",
  "configs": [
    {
      "name": "element",
      "locationPrefix": "projects/element-ng",
      "keysFile": "projects/element-ng/translate/si-translatable-keys.interface.ts",
      "keysInterfaceName": "SiTranslatableKeys",
      "messagesFile": "dist/@siemens/element-ng/template-i18n.json"
    }
  ]
}

• files is a glob pattern for defining the files to scan
• configs is an array of configs. For mono-repos building multiple libraries, they can be separated into different configs. All keys are required:
  • name is a unique name
  • locationsPrefix defines the path prefix of the source files, important to distinguish between different libraries in a mono-repo
  • keysFile defines the path of the generated TypeScript interfaces file
  • keysInterfaceName defines the name of the TypeScript interface
  • messagesFile defines the path of the generated messages JSON file

Testing

Run npm run translate:test to perform the unit tests via Karma. You can set a seed for running the tests in a specific using an environment variable: SEED=71384 npm run translate:test
