@siemens/element-translate-ng¶

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
