## Description

[Connect](https://github.com/senchalabs/connect) your [Express](https://expressjs.com) application to an [Azure Function handler](https://docs.microsoft.com/en-us/azure/azure-functions/functions-reference-node), and make seamless usage of [all middlewares](http://expressjs.com/en/guide/using-middleware.html) you are already familiar with.

## Usage

In your `index.js`:

```js
const createHandler = require("azure-function-express").createHandler;
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 = createHandler(app);
```

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

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

To allow Express handles all HTTP routes itself you may set a glob star route in a single root `function.json`:

```json
{
  "bindings": [{
    "authLevel" : "anonymous",
    "type"      : "httpTrigger",
    "direction" : "in",
    "name"      : "req",
    "route"     : "{*segments}"
  }, {
    "type"      : "http",
    "direction" : "out",
    "name"      : "res"
  }]
}
```

Note that `segments` is not used and could be anything. See [Azure Function documentation](https://github.com/Azure/azure-webjobs-sdk-script/wiki/Http-Functions).

All examples [here](/examples/).

## Log via context

The [log function](https://docs.microsoft.com/en-us/azure/azure-functions/functions-reference-node#writing-trace-output-to-the-console) is the only [context](https://docs.microsoft.com/en-us/azure/azure-functions/functions-reference-node#context-object) function made available. You can access through `req.context.log`:

```js
app.get("/api/hello-world", (req, res) => {
  req.context.log({ hello: "world" });
  ...
});
```
