azure-function-express

Allows Express usage with Azure Function

Description

Connect your Express application to an Azure Function handler, and make seamless usage of all middlewares you are already familiar with.

Usage

In your index.js:

const createAzureFunctionHandler = require("azure-function-express").createAzureFunctionHandler;
const express = require("express");

// Create express app as usual
const app = express();
app.get("/api/:foo/:bar", (req, res) => {
  res.json({
    foo  : req.params.foo,
    bar  : req.params.bar
  });
});

// Binds the express app to an Azure Function handler
module.exports = createAzureFunctionHandler(app);

Make sure you are binding req and res in your function.json:

{
  "bindings": [{
    "authLevel" : "anonymous",
    "type"      : "httpTrigger",
    "direction" : "in",
    "name"      : "req",
    "route"     : "foo/{bar}/{id}"
  }, {
    "type"      : "http",
    "direction" : "out",
    "name"      : "res"
  }]
}

You can have a single function.json that matches all HTTP routes with binding "route": "{*segments}". And let Express handles routing.
