To utilise some features of modern browsers, you need to be operating over a secure https connection. By default, the NextJS development server runs on http.

Here’s how:

• Generate a certificate for localhost
• Add the certificate to keychain
• Update server.js to use the certificate and require https
• Update package.json scripts

Generate a Certificate for localhost

You can create a certificate using OpenSSL with this command:

openssl req -x509 -out localhost.crt -keyout localhost.key \
  -days 365 \
  -newkey rsa:2048 -nodes -sha256 \
  -subj '/CN=localhost' -extensions EXT -config <( \
   printf "[dn]\nCN=localhost\n[req]\ndistinguished_name = dn\n[EXT]\nsubjectAltName=DNS:localhost\nkeyUsage=digitalSignature\nextendedKeyUsage=serverAuth")

This command will generate the certificate and the key:

TL;DR

These are the Principles of Architecture at ResponseTap. They are used to guide everything we build in the ResponseTap Engineering team:

1. Serverless First. Cloud-First. AWS First.
2. Configure First. Write Code Second.
3. Simplicity is better than complexity.
4. Massively Scalable. Event-Driven.
5. What we build will fail. We embrace those failures.
6. Services are modular, isolated and single purpose.
7. Services provide an interface and are ignorant of how they are consumed.
8. Change is sought but challenged.
9. Business logic is ephemeral, preferably stateless and computed late.
10. Principle of Least Privilege.

Read on to find out why each of these principles has been chosen.

Registering and validating custom email addresses in Route53 and Simple Email Service (SES) doesn’t need to be difficult. But there is almost no documentation to show you how to do this easily. Here’s a simple solution.

Buying a Custom Domain via the Route53 console on AWS is really easy. They cost anything from $9 up. With help from some good documentation, you can be set up in a matter of minutes.

Once you have your domain, you can get up and running with a static website quickly as well. As static websites become more and more popular there are lots…

Setting up any personal machine is mostly about personal choice. The following are suggestions, based on my opinion. But, there’s lots of stuff here, see if you can find something that helps you. ✌️

Especially for my friend, Mark stevens.

Upgrade OS

Recent releases of Catalina have been somewhat problematic. Upgrading has caused some known issues with Wifi config, for instance. So before you go installing lots of tools and changing lots of configuration: upgrade to the latest OS Version.

A fundamental principle of building systems in a serverless world is that your functions should do their job as quickly as possible. The longer functions run, the more they cost.

Regardless of what your Lambda functions are doing, in the majority of use cases, a big slice of the processing time will be spent sending data somewhere else.

If the goal is super-fast Lambdas; and sending data costs so much time, we should be trying to make this action as efficient as possible. The solution is batching data before sending.

I suspect the majority of contributors on Medium are like me. I’ve written this post for those people, sharing my experience over the past four months. I’ve learned a few things that have helped me write better, more quickly and with more fun.

This article isn’t the first Medium post about writing on Medium! There are so many it is a cliche. But many of these great stories are aimed at writers or aspiring writers.

I don’t consider myself a writer. Nor do I aspire to be a serious writer.

For me, writing is a hobby. It’s not part of…

If you’ve never used Continuous Delivery before, it can be an ominous prospect!

All those tools, all that tech, where do I even start!?

That is precisely how I felt when I first encountered Continuous Delivery. Like most things in Software Engineering (and life), the hardest step can be the first. That’s why I’ve written this guide to get you from rookie to continuous delivery in minutes! I’ve provided all the code and config that you’ll need.

What is Continuous Integration (CI) and Continuous Delivery (CD)?

Continuous Integration — a development practice that requires developers to integrate code into a shared repository several times a day. Each check-in is…

A reliable, safe place to store your code is essential. Whether you are working alone or as part of a large team, source control will help you to manage your code.

When developing a new product, Software Engineers need to focus on the product. Concentrating on maintaining other services, like source control or delivery pipeline platforms is a waste of their time. AWS CodeCommit is a managed service, which means that Engineers do not have to spend time on maintaining or configuring it. It just works.
