In preparation for Chrome’s Not Secure flag, which will update the indicator to show Not Secure when a site is not accessed over https, we wanted people to be able to test whether their site would pass. If you read our previous blog post about the existing misconceptions around using https, and preparing your site, you may have noticed a small fiddle, allowing you to test which sites will be deemed “Secure”. In preparation for the blog post itself, one of our PMs approached me asking for help making this fiddle come to life. It was a simple ask: we need an endpoint which runs logic to see if a given domain will automatically redirect to https.

The logic and requirements turned out to be very simple:
Make a serverless API endpoint
Input: domain (e.g. example.com)
Output: “secure” / “not secure”

Logic:

if http://example.com redirects to https://example.com
	Return “secure”
Else
	Return “not secure”

One additional requirement here was that we needed to follow redirects all the way; sites often redirect to http://www.example.com first, and only then redirect to https. That is an additional line of code I was prepared to handle.

I’ve done some Continue reading

Our Workers platform can be used for a ton of useful purposes: for A/B (multivariate) testing, storage bucket authentication, coalescing responses from multiple APIs, and more. But Workers can also be put to use beyond "HTTP middleware": a Worker can effectively be a web application in its own right. Given the rise of 'chatbots', we can also build a Slack app using Cloudflare Workers, with no servers required (well, at least not yours!).

What are we Building?

We're going to build a Slack bot (as an external webhook) for fetching the latest stock prices.

This Worker could also be adapted to fetch open issues from GitHub's API; to discover what movie to watch after work; anything with a REST API you can make query against.

Nevertheless, our "stock prices bot":

• Uses the Alpha Vantage API to fetch stock prices
• Caches a map of the top equities to their public identifiers, so you can request /stocks MSFT as a shorthand.
• Leverages Cloudflare's cache to minimize the need to hit the API on every invocation, whilst still serving recent price data.

Using the cache allows you to improve your bot's response times across all invocations of your Worker. It's also polite Continue reading

Our newest data center is now live in Tel Aviv, Israel! This expands our global network even further to span 135 cities across 68 countries.

High-Tech in Israel

Although Israel will only be turning 70 this year, it has a history so rich we’ll leave it to the textbooks. Despite its small size, and young age, Israel is home to one of the largest tech scenes, often referred to as Start-up Nation.

Haifa’s Matam technology park houses a few tech giants’ offices including Intel, Apple, Elbit, Google, IBM, Microsoft, Yahoo, Philips and more. Meanwhile, Tel Aviv serves a true hipster capital, with a high concentration of great coffee shops to serve its many startup employees and founders.

Some brag-worthy Israeli inventions include flash drives, Waze and cherry tomatoes. This is due to Israel’s excellent education. Israel is home of the top universities in the world, bringing Israel to be one of the top five nations in scientific publication per capita output. Israel also has one of the highest PhD and MD degrees per capita, and among of the highest nobel laureates per capita as well. Israeli mothers, your nagging has paid off.
