Kraftwerk Speak Server

Setup

You need Google Application Default Credentials (ADC) to authenticate with @google-cloud/text-to-speech. See the GoogleCloud documentation about this

In the end you'll get a JSON file from Google to which you needd to set a environment variable GOOGLE_APPLICATION_CREDENTIALS with absolute path to the ADC file.

Redis for caching

The server caches the responses with redis. To have a local instance running, you can just start one with docker-compose:

$ docker-compose up -d

Install node dependencies with pnpm

$ pnpm install
$ pnpm run speak-server:serve:dev
