NLP-API

This hopes to cover some Natural Language Processing use-cases through a rest api.
This is intended to start as a presidential-inaugural-address collection, with some nlp processing applied to the speech text.

Use A MongoDB Datastore

This is expected to connect to a mongodb data store.
Setup some env vars: i think for now i'd recommend your.env file.

MONGO_AUTH=false
MONGO_DB_HOST=<your-mongo-hostname>
MONGO_DB_PORT=<your-mongo-port>
MONGO_DB_USER=<your-db-username>
MONGO_DB_PW=<your-db-pw>
SERVER_PORT=<a-port-for-the-api>

• server_port can be a port you'd like to use to expose the api on. The default port, expressed in the code, is 3000

Run With Docker

• cd into this directory & build the api image: something like docker build -t nlp-api:1 .
• run the image as a container: something like docker run --name nlp --env-file <>your.env -p 3000:3000 nlp:1

Getting Data Into The DB

Here's some thoughts on loading data into the db

Authentication

A series of "handshakes" are provided so that a browser, as well as a user, can be authenticated to "use" the api.

Authenticating a browser

2 network requests are in effect to provide jwt auth for the browser:

• app/init
  • client should provide the expected id query param
  • api returns a jwt
• app/allow-access
  • client should provide the jwt from the previous request in an authorization header as a bearer value
  • api returns a different jwt
  • client should use this jwt to start the user-login workflow

Authenticating a user

• /users/email
  • client should use the jwt from the previous api
  • client should pass the user's email address as req.body param
• /users/pw
  • client should use the same jwt from the previous apis
  • client should pass the user's email address && password as req.body param
  • api returns a new jwt that the client can use throughout the api usage (per jwt matching user+app criteria etc)
