AllenNLP Demo

This repository contains the AllenNLP demo.

Here is an example for how to manually build the Docker image and run the demo on port 8000.

$ export GIT_HASH=`git log -1 --pretty=format:"%H"`
$ docker build -t allennlp/demo:$GIT_HASH .
$ docker run -p 8000:8000 allennlp/demo:$GIT_HASH

Development

To run the demo for development, you will need to:

1. Create a fresh environment:

   conda create -n allennlp-demo python=3.6
   source activate allennlp-demo
   pip install -r requirements.txt
   

   Note that this will install the latest released version of AllenNLP - to use a version which you have been working on, run python setup.py install in the root of your clone of allennlp.

2. Build the frontend and start a development frontend service

   ./scripts/build_demo.py
   cd demo
   npm run start
   

   This will start a frontend service locally, which will hot refresh when you make changes to the JS.

3. Start a separate backend service

   ./app.py
   

   Normally, the backend server would manage the frontend assets as well - the JS has a special hack for if it is running on port 3000 (which it does by default if you are running the unoptimized JS using npm run start), it will look for the backend service at port 8000. Otherwise, it serves the backend and the frontend from the same port.
