RosaeNLG node.js Server
Install & Run the server
mkdir my-rosaenlg-server
cd my-rosaenlg-server
npm init --yes
npm install rosaenlg-node-server
npx rosaenlg-serverSet the port using environment variable ROSAENLG_PORT. Default is 5000.
By default, templates are not saved permanently: the server is empty when it starts, you can upload templates and render them, but they are lost when the server is shut down.
To save templates, you must provide a path to the disk by setting the environment variable ROSAENLG_HOMEDIR.
Templates will be saved when uploaded (as json files), and reloaded when the server restarts.
You can also push new templates directly on the disk (using CI or whatever) and ask the server to reload them, without having to restart the server.
The server is provided without any security so you should only use it in a microservice architecture, and never make it publicly visible.
Documentation, swagger, OpenAPI
When running the server, the documentation is directly available: http://HOST/api-docs
Packaging the templates
RosaeNLG templates are typically developped on a node.js environment, as RosaeNLG is primarly a JavaScript library. Once the templates are developped, you can package them in a JSON package (instead of having multiple .pug files, which is not practical), deploy them on RosaeNLG Java Server and render texts.
To package the templates, use the Gulp RosaeNLG plugin.
