Git fast-forward merge - why you should turn it off | Better Dev
We investigate what is Git fast-forward merge mode behavior, how does it affect repository history and why one should think about disabling it.| Better Dev .blog
I thought minimizing Lambda function code was a best practice for Lambda optimization - it's even recommended by AWS in a not-so-old blog post. Turns out, I was wrong.| Better Dev
Integration testing for serverless Event-Driven Architecture is as necessary as it is time-consuming. Boilerplate code to write, long waiting for tests completion, tedious debugging. But no more.| Better Dev
AWS re:Invent 2023 ended, so let's look at the most interesting announcements for serverless and more. There are exciting features to try and, maybe more importantly, features to avoid!| Better Dev
With some creativity, we can use Lambda Response Streaming to dynamically show status updates, like the progress of long-running processes. And with proper TypeScript types and generator functions, we can write clean, dynamic content streaming Lambda with composable payload enrichers that will impress your work colleagues (if they are into this stuff).| Better Dev
Lambda Response Streaming allows sending incremental responses, but those response chunks can arrive long after you write them. They are buffered in a rather unexpected way, delaying all messages you stream. But there is a workaround to force the stream to flush.| Better Dev
I recently created a CDK library provisioning a CI/CD pipeline for serverless apps on AWS. Having finished the "regular" JS library, it took me a day to convert it to a "proper" CDK Construct library. Not long, and I learned a lot. Here are my thoughts and tips.| Better Dev
CDK generates Logical IDs used by the CloudFormation to track and identify resources. In this post, I'll explain what Logical IDs are, how they're generated, and why they're important. Understanding this will help you avoid unexpected resource deletions and baffling "resource already exists" errors during deployment.| Better Dev
Security is not convenient. That's probably why the CDK, by default, uses AdministratorAccess Policy to deploy resources. But we can easily change it and increase the security of our AWS account, following the least privilege principle with a minimal additional burden.| Better Dev
After some time, I accumulated enough articles to share. They are about cloud, tech, programming, and work, and also include two games, a petition, and a survey.| Better Dev
Have you ever been stuck deciding between SQS, SNS, Kinesis Streams, and EventBridge? Struggled to pick the right one for your use case? If the answer is "yes", I've got you covered with a simple decision tree to help you make the right decision.| Better Dev
In need to backup my personal files in the cloud, I wrote a script that archives the data into the Amazon S3 bucket. After some fine-tuning and solving a bunch of edge-cases, it's limited mainly by the disk read and my internet upload speed. And it costs me only $3.70 per TiB per month.| Better Dev
The simplicity of setting up a Kinesis trigger for a Lambda function may be deceptive. There are pitfalls that can cause problems we will spot only later, in the production environment. I learned about some of them the hard way, so let's say I speak from the experience.| Better Dev
Two articles about the Blockchain on today's list. Both are not in favor, I'm afraid. Apart from this, some tools, work thoughts and advice, and again an article so weird I couldn't categorize it.| Better Dev
Can you have a website with a CMS on AWS and not pay just for its existence? I looked at Amazon Lightsail, headless WordPress, and Webiny CMS but found none of those suitable. So I choose Prismic – a SaaS headless CMS, and Gatsby to create the site. Yes, I needed to make a pipeline to build my website after content changes. But when I did it, I got a website with CMS hosted at no cost.| Better Dev
AWS can overwhelm with the number of services. Especially if multiple services seem to do a very similar job. Let's look at the cloud-native AWS messaging services – the SQS, SNS, Kinesis, and EventBridge. What are the differences and when to use which one?| Better Dev
Here we are again, with selected content from all over the internet about tools, tech, cloud, programming, work, and a single article I couldn't categorize. Probably because I'm still in shock after reading it.| Better Dev
I know my coworkers and teammates are reading this, and probably my boss as well. But let's risk it.| Better Dev
There are two reasons to optimize AWS Lambda functions performance. First is money – you pay for the Lambda execution duration. The quicker you do the job, the less you pay. The second is latency – the quicker you do the job, the shorter your client waits for the result. It's a known fact that the decrease of latency improves sales, user engagement, and client satisfaction – so we could argue it's also the money, in the end.| Better Dev
Two months after the previous edition, I gathered enough interesting resources to share them. In this edition, you will find content about HTTP, WebDev, versioning, tech, and problem solving.| Better Dev
The new version of AWS SDK for JavaScript / TypeScript / Node.js came with a few significant improvements. But does "General Availability" mean "ready for the production"? How to use it? And how to unit test our code using it? Let's take a look at it.| Better Dev
Logging in AWS Lambda functions is simple. You just print the message, and it's sent to the CloudWatch Logs. And everything is fine until you get a surprisingly big bill for the CloudWatch usage, or you need to actually debug some live system. Here are my tips for logging in AWS Lambda, based on my experience with real-live, big-scale functions running on production.| Better Dev
Welcome to the first issue of Things I Found Interesting – an irregular series of links to, well, interesting content. Below are eleven articles and resources on various software-related topics, which I stumbled upon in the last several weeks.| Better Dev
Buckle up, for some of you this may be controversial, but maybe for some others – obvious. This is how to prevent a problem causing your application to out of the sudden stop behaving correctly, or, even more funny, stop behaving correctly only on one developer's computer. We can solve this with one two simple tricks.| Better Dev
Here I show three ways to create Amazon Athena tables. More importantly, I show when to use which one (and when don't) depending on the case, with comparison and tips, and a sample data flow architecture implementation. Also, I have a short rant over redundant AWS Glue features. All in a single article. Enjoy.| Better Dev
Bash scripts. Almost anyone needs to write one sooner or later. Almost no one says "yeah, I love writing them". And that's why almost everyone is putting low attention while writing them.| Better Dev
There are multiple articles on how to host a static website or Single Page Application (SPA) on AWS. But they rarely go into the topic of setting up the environment variables for the frontend application.| Better Dev
Developers, like all specialists, discover and collect their favorite tools over time. Having a good, proven set of tools makes the work easier and more pleasant. We can focus on getting the job done. Sometimes eliminating minor inconveniences or improving a small element of everyday activity makes the greatest impact on the comfort of work.| Better Dev
Amazon API Gateway provides an option to export the API schema as an OpenAPI Specification. With it, we can display our REST API as an interactive website. But we do not get a public URL to that specification file which we could use as a source for an interactive page like Swagger. Instead, we can only get the file from the AWS Console, CLI, or SDK.| Better Dev
Many of the scripts and executables allow providing some command line arguments. They may be required or optional. There are flags, that are just switches changing command behavior. There are, of course, arguments with values. And there are so-called positional arguments – parameters given in some order without any extra indications.| Better Dev
Git allows us to define aliases, which are basically our own commands we can use. They may be just a calls for other commands with parameters, or even shell scripts. Possibilities are unlimited.| Better Dev
How many times did you try to make git push for a newly created branch to the remote repository, only to get a strange "no upstream branch" error? Here I will show how to change Git configuration with a single command to get rid of it for good.| Better Dev
