nta_flask

Flask restful API for the nta_app backend

This app is normally deployed as a submodule using docker-compose or kubernetes with the full QED application available at https://github.com/quanted/qed

Development Deployment

For development purposes it can be deployed locally from the home directory of this repo by changing line 14 of flask_nta.py to import 'dsstox_rest' rather than 'nta_flask.dsstox_rest'

To deploy locally, run the following commands from the top directory in the repo

$ export FLASK_APP=flask_nta.py
$ flask run

The application will come up on http://127.0.0.1:5000/. To test the application, POST the following request to http://127.0.0.1:5000/rest/ms1/batch/1

{
   "search_by":"mass",
   "query": [
       500,
       600
   ],
   "accuracy":1
}
