Type definitions for Azure Functions

This package contains type definitions for using TypeScript with Azure Functions.

These typings are for common objects that will be passed to your Azure Functions function code. Azure Functions supports TypeScript development, but does not support directly running TypeScript code without transpilation.

Read more on configuring entry points in your Azure Functions function app.

Install

Because this package only contains TypeScript type definitions, it should be saved under devDependencies.

npm install @azure/functions --save-dev

Usage

import { AzureFunction, Context, HttpRequest } from "@azure/functions";

const index: AzureFunction = async function (context: Context, req: HttpRequest) {
    context.log('JavaScript HTTP trigger function processed a request.');
    if (req.query.name || (req.body && req.body.name)) {
        context.res = {
            status: "200",
            body: "Hello " + (req.query.name || req.body.name)
        };
    } else {
        context.res = {
            status: 400,
            body: "Please pass a name on the query string or in the request body"
        };
    }
}

export { index };

Versions

Versioning of @azure/functions is tied to the version of the Azure Functions Node.js Worker the types were generated from. You can find the Azure Functions Node.js Worker version of a given Function Runtime Version here. It is recommended that you take the latest version available.

Getting Started with Azure Functions

If you are getting started with Azure Functions, you can follow this tutorial to create and deploy your first JavaScript function. We recommend that you use Visual Studio Code and the Azure Functions extension.

The Azure Functions developer guide and the JavaScript-specific developer guide are good resources to gain an understanding of more Azure Functions concepts.

README

io-functions-commons

Common code across Azure functions of project IO.

To release a new package on GitHub and npm:

yarn release-it <minor|major|patch>

Upgrading from 13.x to 14.x

Version 14.x is the first version that uses italia-utils 5.x,
a major upgrade to the package that generates the provided Typescript definitions.

This translates in the fact that you must upgrade italia-utils to a version >= 5.x
if you want to upgrade your deps using io-functions-common 14.x.

@types/mime

Author: Unknown

does SPID login work without this?

I guess the result of this call can be cached using appcache, what about this?

+      log.error(`static|Error retrieving static file asset|error:%s`, err);
+      return next(err);
+    }


It's not clear to me why we introduced this behaviour. Besides that, we can put this in a middleware function (req, res, next)=>void and we can give this chunk an explicit meaning.

This logic is required because the express default static folder (ref) doesn't work inside Azure functions. Here we emulate what static middleware does. We can create a specific middleware, but this code will be used only on this endpoint.

we can just move it in a function declared inside the same module

Fixed in 94282ce
