Hi Folks,

Last week was a big week for me and the team at Platformatic– we finally launched v1.0.0, and I could not be more excited to share it all with you!

This launch is important because it includes features I was desperate to have during my many years as a software consultant. What we released last week would have saved me countless hours, headaches, and deployment errors. While I can’t turn back the clock, I look forward to seeing others in my position have access to Platformatic and avoid these issues. So, what did we ship?

1. Breaking Change Detector: Offers a view of a change's impact on the public API level of your microservices ecosystem and which teams it will affect. The detector maps out dependencies and interactions with OpenTelemetry. I recorded a demo showing you how it works We looked at why a tool like this is essential, how it can help enterprise teams, and how it works in more detail here.
2. Stackables: Take your configurations, package them into shareable modules, and publish them on your internal npm registry, enabling teams in your organization to access and utilize the same core configuration. Check out the demo I recorded on how to use them or took a look at how Stackables work and how they can benefit your development team.
3. Platformatic open source goes 1.0.0, which means no breaking changes for a while.

Hi Folks,

As I'm writing this, I have been working hard for the Platformatic v1.0.0 launch on Tuesday, the 26th of September (tomorrow as you are reading this). Register to be part of the excitement!

I wrote a (research) paper!

After almost 10 years of defending my Ph.D., I would have never imagined that. I got back to writing a research paper as part of my startup. As part of our business research in Platformatic, Luca Maraschi and I identified a critical problem every adopter of a microservice system had: catch a breaking change in one microservice before it could cause downtime in others. We knew we had to build something new, and we identified an algorithm and an architecture to map the complete network of microservices in a system and calculate a percentage of risk.

Hi Folks!

As I write this, I'm on a plane to London, where I will spend the entire week working with my co-founder, Luca Maraschi. Since I last wrote, there has been quite a bit of news.

Bun 1.0

Bun hit the 1.0 release, and I'm both excited and disappointed. I really like what Jarred Sumner is building with Bun, but I'm a bit frustrated by their compatibility claim with Node.js. In my experience, it's not a drop-in replacement, and many inner details differ. This results in many random issues over my repos asking for fixes for Bun incompatibilities while people try it out. I would have preferred if they waited for calling a 1.0 to reach greater compatibility with the ecosystem.

Hi Folks! The last few weeks have been incredibly busy. In this edition I include a brief explanation of Logging - the process of creating log lines as a byproduct of an application. Read up!

I’ve included all last releases for modules, barred Platformatic… which we released multiple times per week, working hard to fix all bugs for old and upcoming features!

The dangers of Logging

Hi Folks, Adventures in Nodeland has officially become a biweekly newsletter! You'll receive news from the Fastify ecosystem every two weeks - with some leeway while I'm traveling.

Let's recap what happened since the last edition!

Videos

Have you ever wondered what technical principles inspire the Fastify community? Check out my latest video https://youtu.be/43X1VqlZTQ8.

Hi Folks,

A lot happened in the last few weeks! This edition of Adventures in Nodeland includes three talks I delivered in the latest spring 2023 season, the recordings of two live streams, many releases, two articles I have authored, and many interesting articles I've read that I have found very useful.

Talks

In this talk that Luca Maraschi and I delivered last June at JSNation, we explore the story of backend APIs and the good and bad of every generation of technologies. We also launched a few new things, doing a live release on stage! Watch the end of the video; you can't miss it. It starts at 20:48: portal.gitnation.org/contents/apis-are-evolving-again.

Hi Folks,

Two weeks have passed since the last Adventures in Nodeland edition. I have been swamped catching up with my backlog, and it is not getting shorter. I'm currently at 100+ notifications on GitHub to process: if you have been waiting for me for anything, let me know.

This newsletter explains one of the questions I got asked the most: "What test framework do you recommend," and I've been trying to answer. Then it includes a couple of video links as well as quite a lot of releases and articles.

What do I look for in a Node.js testing framework?

Hi Folks,

The last few weeks have been beyond hectic. Last week we launched the new features of Platformatic at JSNation 2023 in Amsterdam. I will cover all the details and a few notable articles and releases. Let us know!

Hi Folks,

As I write those lines, I'm on a short flight between Bologna and Amsterdam for the week. Soon, I'll be keynoting JSNation with my Co-Founder and CEO Luca Maraschi, announcing the whole scale of Platformatic goals to the world. While we have been shipping weekly releases and constant improvement, we seldom presented the tech world with our goal. We are unveiling the new things we worked on in the last few months. On June 1st, we are releasing something new that was not possible before with Node.js.

Register at https://papilio.platformatic.dev/launch-signup to for all details.

Hi Folks, I was in Vancouver last week to meet the OpenJS crowd at Open Source Summit and Platformatic Co-Founder Luca Maraschi! It has been a blast of a week - despite being busy, quite a few things happened anyway, so here is the usual newsletter format!

Videos

Should you build a monolith? Should you go for microservices? How about adopting an architecture that can scale well in complexity? Check out my latest talk: building a modular monolith with Fastify at: https://portal.gitnation.org/contents/building-a-modular-monolith-with-fastify.

I’ve been working on a new Pull Request for Node.js Core during my latest stream: vm.NodeReam. Here is the current status of work in PR 47855.

Hi Folks,

This edition of Adventures in Nodeland was put together in Schipol, on my way to Open Source Summit North America 2023, where I would participate in a panel on creating Open Source communities, a topic I spoke about before.

This edition includes my commentary on a recent article from the AWS team, many releases, and a couple of exciting articles.

Was serverless a lie?

Hi Folks,

Almost two weeks have passed since the last update. Things are hectic at Platformatic between conferences, new features, and bug fixing. This edition links everything we released in the last two weeks, including two essential security updates for @fastify/csrf-protection and @fastify/passport.

Platformatic

In the last two weeks, we have published much Platformatic content. We have introduced the new platformatic deploy command. We have published a new guide on how to integrate Platformatic with Auth0 and Next.js, building a secure frontend with a secure backend. We have released our interviews: * Luca’s interview * my interview Last but not least, here is an article explaining why we are building Platformatic: “The Business case for extensible APIs”.

Hi Folks,

A couple of weeks have passed since the last issue of Adventures in Nodeland. I’m sorry I could not send you an update sooner. I have been traveling to Verona for JSDay and Berlin for NodeCongress. I overextended myself - I should have known better after many years of travel. As a result, this newsletter slipped for almost two weeks and a half. It’s now packed with information and links!

Node.js v20 is now available

Node.js 20 is now available!, and it’s packed with new features:

Hi Folks,

Last week was the first organized "launch week" of Platformatic. As a result, we published articles, videos, and even a conference talk! It was truly unique.

Please look at the recap blog post we put together. Here you can find the announcement video with Luca and myself as well.

Upcoming Node.js CFPs

Hi Folks!

This edition of Adventures in Nodeland is special. We have reached the 100th mark. Thank you for being so supportive and following me on this journey!

Platformatic Launch Week Recap

This week we made our cloud available to everyone for free. This includes:

Hi Folks,

In this edition you will find only a few releases - the TODO list for modules to be released is growing! I have been quite busy preparing for next week.. as we will unveil our next step.

Platformatic Launch Week

Hi Folks!

This weekend of turmoil for the startup world ended well. This is the best outcome for all our industry, so I'm glad everyone would be able to meet payroll, and there would be no layoff due to the SVB crack.

Videos

In this live stream, we finished the porting to PostgreSQL and implemented the election algorithm. Our progress is visible at https://github.com/platformatic/unscalable-queue-system/pull/39.

Hi Folks, Last week I have been traveling to visit one of the first companies to adopt Platformatic. I'm excited! Nevertheless, this issue covers the usual batch of releases and articles. Check them out!

Videos

What if I told you Fastify has first-class typescript support, allowing for typed requests and replies? And you could use those types to validate the incoming data, avoiding potential security and consistency issues.

In my latest youtube tutorial, Type-Safe Fastify I show how to integrate @sinclair/typebox with Fastify using @fastify/type-provider-typebox!

Hi Folks,

I’m writing these lines en route to the first on-site meeting with a company using Fastify and Platformatic. I’m excited that we are moving fast. In this edition, we cover quite a few things: first, I will be talking about an app that I love. Then, we cover the latest Node.js core release, finishing with new videos and articles.

We are also planning some big news for Platformatic. Subscribe to our newsletter at platformatic.dev or join our discord.

Thanks for reading!

Hi folks,

Last week has been incredibly busy with all the security updates as well as new content, and a new Platformatic release. As usual, let me know what you think!

Videos

Last Monday, I paired with Matthew Phillips of the Astro team to build together fastify-astro. We got almost all the features of the development mode working! Check out the video; there are quite a few tricks that you can use in your code too!

Hi Folks,

Last week I visited Milan for a Platformatic team retreat! It was a great experience, and we planned several features for Platformatic! I also spoke at the “Milano Frontend” meetup, presenting Platformatic DB!

fastify-astro

Hi Folks, in this edition of Adventures in Nodeland, you can find a few new releases (Platformatic, Mercurius, Pino, and Fastify), as well as many interesting articles with my brief comment. Even if it’s unrelated, I’ve spent the last weekend with my daughter Zoe (you can find a shot I took at the park) - while I should have likely gone to FOSDEM. I’m happy I stayed home because we had such a great time.

Videos

Last week I streamed twice about the Unscalable Queue System:

• Unscalable Queue System - Part 8
• Unscalable Queue System - Part 9

Hi Folks,

In this edition of Adventures in Nodeland, I’ll try to do my part and help folks in need after the massive layoffs in tech. I also include the links to my latest videos in case you missed them, with two streams and a new tutorial. Rember to scroll down to releases and articles too, as there are a few notable links!

Fastify Jobs

In the latest few weeks, many companies laid off staff. I’m happy to use my platform to help folks find a relevant job. Here is a list of companies that I vetted, and they are all seeking Fastify experience. Check them out:

Hello folks! Here are the latest adventures in Nodeland, between building a small microservice live, many releases, and a few exciting articles!

Videos

I keep streaming the building of Unscalable Queue System:

• Part 5 - retries and authentication
• Part 4 - retries
• Part 3 - PR testing with Platformatic Cloud.
• Part 2 - project now works.
• Part 1 - project creation

Hi Folks!

This edition of Adventures in Nodeland is packed! The most exciting piece is the live stream I did with Kent C. Dodds on fixing the memory leaks on his website, check it out. I’m also announcing a new Fastify course at JSDay 2023. There are also a lot of releases, including a security vulnerability in mercurius.

Videos

This week I helped my friend Kent debug the memory leak to his website. You can read the full article at https://kentcdodds.com/blog/fixing-a-memory-leak-in-a-production-node-js-app, as well as watch our debugging session live on YouTube: https://www.youtube.com/watch?v=vkys6Wk-jYk.

Hello everyone, I’ve never done one of those “my year in review” blog posts, but this year has brought many changes that I’m grateful for, and I would like to celebrate with you. I’m writing these lines while traveling with my family from Portugal.

2022 has been a busy and exciting year, culminating in the founding Platformatic, a new platform that helps developers build, deploy, and scale their applications.

Since its launch, Platformatic has garnered a lot of attention from businesses and developers alike, and we’ve been fortunate to work with excellent developers that are testing it out! I’m proud of the team we’ve grown and our progress; there is much more to come. In the last few weeks, we launched Platformatic Cloud: we aim to revolutionize how you all deploy the backend APIs for your frontends ;).

In addition to Platformatic, I’ve been focused on continuing my work as a speaker and author, sharing my insights and experiences with audiences worldwide. I’ve had the opportunity to speak at several conferences and events, and I’m always grateful for the opportunity to share my knowledge with others. My most significant success was the “Lead by example” award I received at OpenJS World in Austin.

Hi Folks,

I’m sorry I couldn’t send an edition of Adventures in Nodeland last week. Last week was extremely busy. My family went to London from the 8th to the 12th of December. On our way home, we had a travel nightmare: British Airways canceled our flight from London to Bologna. We had to figure out an alternative travel plan to get back home asap, as Zoe was starting to get sick. We crossed the Channel on a Eurostar train and flew out from Paris! What an adventure! On the 14th I traveled to Malaga for WeyWeyWeb, a unique Yey Yey conference! There I demoed Platformatic Cloud on stage for the first time.

Platformatic Cloud

I’m incredibly proud of the work my team at Platformatic did in the last few months. Since the announcement of Platformatic DB, we have been focusing on building our cloud. You can read the announcement on our blog or watch the demo.

Hi Folks, we had a flurry of releases last week. Platformatic v0.8.0 includes some exciting features. The Fastify community also started a complete rewrite of all the typings to support the new TypeScript nodenext resolution.

Node.js Backend Master Class

Next week, I will do a Node.js Backend Masterclass, teaching how to structure Node.js applications (link on the image).

Hi Folks, last week has been exciting. I traveled to London to speak at HalfStack and Modern Frontends Live. I’ve met a lot of old friends, as well as met a few folks I only talked to online.

HalfStack was like attending a full-day concert of your local band. Thanks Dylan for organizing it, I would definitely recommend everybody to attend.

I was disappointed by Modern Frontends Live. I expected the talks to be recorded (and live-streamed), so many people could watch them, but the organizers let us down. Take a moment to read Jo Frachetti‘s review. On the bright side, the speaker lineup of the conference was stellar, and I met so many internet-only friends there. I hope to spend more time with them at future events.

Issue #84 - A new home

Hi Folks,

I’ve migrated my newsletter from Revue to buttondown.email. This has three benefits: I can write the editions in Markdown. Secondly, the layout will be minimal, reducing the email length and improving readability. Thirdly, I’m now paying for a service I use, which is a great feeling.

This newsletter will stay free. If you want to support my work, please donate via my GitHub Sponsors page.

Hi Folks, as I’m writing these notes, Twitter is laying off people and promising to close Revue by the end of the year. This will be the last email on the platform until I can transfer my newsletter to a new home! Hopefully, you’ll be receiving a newsletter next Monday!

Announcements

Last week we shipped Platformatic v0.5.0, check out the announcement blog post:

Hey Folks! As I’m writing this I’m in Ortigia in Sicily waiting for my daughter to wake up. I’m grateful of every moment I can pass with her. Brace yourself for a CRITICAL OpenSSL release - we would need to update all our Node.js installs next week!

OpenSSL November Security Release | Node.js

OpenSSL is releasing a CRITICAL security fix the 1st of November. A Node.js security release will follow thereafter.

Hey Folks! I’ve just landed home 🛬 from an amazing trip to Ireland for the OpenJS Collaborator Summit and NodeConf.eu. While traveling, I skipped editing an edition last week - this edition has quite a few more releases than I would normally do! As usual, feel free to ping me for questions.

Launching Platformatic DB 🚀 with Matteo Collina & Luca Maraschi (JS Party #245)

Patformatic co-founders Matteo Collina & Luca Maraschi join Amal & Chris to discuss their just-announced (and we mean just announced) open source database tool: Platformatic DB!

It’s a daemon that can turn any PostgreSQL, MySQL, MariaDB, or SQLite database into a REST and GraphQL endpoint. What makes it special is that it allows massive customization thanks to the flexibility of Fastify plugins.
