How the browser client works
The original ldf-client library is written for the Node.js environment. The browserify library makes it compatible with browsers.
(Optional) Running in a Docker container
If you want to rapidly deploy this widget as a microservice, you can build a Docker container as follows:
$ docker build -t ldf-client-widget .
Next, configure your widget by creating a
settings.json file in your working directory based on the example.
Next, create a
queries directory in which you should insert the queries that will be present by default in the widget, as is done here.
After that, you can run your newly created container by mounting your current folder to the Docker container:
$ docker run -p 3000:3000 -it --rm -v $(pwd)/:/tmp/ ldf-client-widget
