trnsltr - a translation caching service backed by DeepL

trnsltr is a translation caching service that stores already translated data in (currently) Redis. Words and texts that are not already in cache are going to be send to the DeepL API, will be translated, stored in cache and then being returned.

It brings a separate Vue.js frontend and a Slim Framework based backend.

Backend

Configuration

The backend configuration can be done via environment variables, easily to be changed in a .env file. You can check the .env.example file for configuration vars.

Redis

• REDIS_HOST: default 127.0.0.1
• REDIS_PORT: default 6379
• REDIS_DATABASE: default 0

If you are fine with the default you can remove all REDIS_* config keys from your .env file.

DeepL

• DEEPL_HOST: default https://api.deepl.com
• DEEPL_API_TOKEN [provide your API token]

JWT (Json Web Tokens) For authentication JWT (Json Web Tokens) are used. Please specify a strong secret to encrypt the token.

• APP_API_SECRET: default secret

A requirement for this to work is a working database connection to some users table where all your users are saved. When this is set up, you can use the /auth/token route to get a valid token.

If you want to generate a new users table you can run

$ vendor/bin/phinx migrate

Example for getting a token:

$ curl -d "email=john.doe@example.com&password=test123" -X POST http://trnsltr.localhost:8081/auth/token

Response:

{
    "status":"Success",
    "token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6MSwiZW1haWwiOiJobEBpbnF1ZW5jZS5jb20ifQ.qVLAR8MtHKxg38sCu7sWRZVjLdsd4eONHah4_HcrnHE"
}

Frontend

You can run frontend and backend separately. To configure where your backend is reachable create a .env file in your frontend/ folder or copy the .env.example file.

The variable VUE_APP_API_URL is the url to the backend API. Under which URL you run the frontend is totally up to you.

For authentication against the backend please generate a valid token

VUE_APP_API_URL=localhost
VUE_APP_API_TOKEN=abc123
