{
  "keys": ["tab"], 
  "command": "expand_abbreviation_by_tab", 

  // put comma-separated syntax selectors for which

// the main app file
import express from "express";
import loadDb from "./loadDb"; // dummy middleware to load db (sets request.db)
import authenticate from "./authentication"; // middleware for doing authentication
import permit from "./authorization"; // middleware for checking if user's role is permitted to make request

const app = express(),
      api = express.Router();

// first middleware will setup db connection
