Enviroment variables

You can use .env configuration file to configure Content Element Kit runtime and pass configuration to the content element backend.

There are two types of enviroment variables:

• Content Element Kit variables, used to configure service ports, end-user URLs and runtimes.

• TCE_ prefixed variables; variable names will be casted into camelCase and exposed within config property of HookServices:

  export function beforeSave(element: Element, services: HookServices) {
    const { config } = services;
    // Will print out TCE_ prefixed env variables
    console.log(config);
    return element;
  }

Initialize configuration file by running:

cp .env.example .env

This will create .env file with the following values:

# Service ports
PREVIEW_RUNTIME_PORT=8001
EDIT_RUNTIME_PORT=8002
DISPLAY_RUNTIME_PORT=8003
SERVER_RUNTIME_PORT=8004

# External urls
PREVIEW_RUNTIME_URL=http://localhost:8001
EDIT_RUNTIME_URL=http://localhost:8002
DISPLAY_RUNTIME_URL=http://localhost:8003
SERVER_RUNTIME_URL=http://localhost:8004

# AI service configuration
# If AI_UI_ENABLED is set to true, the AI service will be enabled and model
# id and secret key must be provided.
AI_UI_ENABLED=
AI_MODEL_ID=
AI_SECRET_KEY=

# Content Element env variables; TCE_ prefix is required
# Will be loaded to the server runtime
TCE_TEST=123

Port configuration!

Upon changing the service runtime ports, make sure that external url has the matching port (or is pointing to service).
