Бекэнд на fastify для няшных котят (aura8)

Мы разработали приложение, где пользователь может свайпать картинки, и с учетом лайков пользователя мы генерируем новые картинки. Ниже рассказ, с чем интересным мы столкнулись во время разработки этого приложения.

RE: https://chaos.social/@christopherkunz/115967169847516672

I also heard this week from @mcollina that the #fastify project had - in January alone - seen 50% of the total number of vulnerability reports submitted than in the whole of 2025. When you hear things like that it's not surprising that @bagder 's #curl project has taken the decision to stop using this service. A shame that it's come to this 😥 #security

Curious how Fastify keeps a high‑performance HTTP server stable under load? This breakdown of the “blueprint lock” shows the core idea behind its design.

Универсальный Backend for Frontend для всех платформ RUTUBE

У аббревиатуры BFF кроме Backend for Frontend есть и другая расшифровка — Best Friends Forever. И в контексте статьи это только отчасти шутка. Общение фронтенда и бэкенда не всегда происходит гладко (опустим тот факт, что существует множество мемов о противостоянии фронтендеров и бекендеров): клиент запрашивает данные, бэкенд отдаёт то, что запросили, но часто данных сильно больше, чем нужно, а это значит, что запрос будет возвращаться дольше, фронтенд будет отрисовываться тоже дольше и всё это отразится на опыте конечного пользователя. А что если между фронтендом и бэкендом построить мостик, который распределит нагрузку и сделает всех дружелюбнее? Примерно в этом и состоит суть паттерна BBF, а в статье разберём подробнее: зачем его внедрять и какую роль он играет в масштабировании современных сервисов; как мы реализуем этот подход в рамках RUTUBE, какой профит он нам даёт; почему мы отказались от GraphQL; в чём отличия от API Gateway и как вообще проектировать такие сервисы.

NEST.js — уродливый монстр или мощный энтерпрайз?

Если, когда вы смотрите на NEST.js вас гнетёт необъяснимая тоска. Если вы не можете понять воодушевления и радости от использования декораторов. Если рассмотрение очередного NEST-инструмента вызывает лёгкое недоумение — не стесняйтесь, вы не одиноки. NEST.js – это фреймворк для написания REST серверов под Node.js на языке TypeScript, который потом транспилируется в JavaScript. Он написан поверх библиотеки Express (или Fastify – можно выбрать) и привносит модные концепции – Inversion of Control, Dependency Injection и т. п. в мир JavaScript. Нередко описание этого инструмента сопровождается восторженным настроением. Как мне кажется, эта восторженность несколько преувеличена, сложность излишняя, а чудо-сила отсутствует. Некоторые неудобства вынудили нас отказаться от его использования после нескольких лет разработки.

Безопасное взаимодействие с API: от ошибок к стабильности

Каждый frontend-разработчик сталкивался с ошибкой вида TypeError: Cannot read property 'name' of undefined . Это часть целого класса ошибок в JavaScript, возникающих из-за несоответствия фактического формата данных ожидаемому. В этой статье расскажу, как избавиться от подобных проблем и добиться стабильности, внедрив три ключевых шага: API-слой , Backend-for-Frontend (BFF) и проверку с помощью Zod .

Hi!

I'm Adrian, a FullStack #Developer looking for a job either in #Québec (or from it if you allow for remote work). I already have a permanent and open visa

I have experience building and maintaining web apps and APIs, designing systems, doing #DevOps and a bit of #BigData, #MachineLearning and #IoT

I'm experienced using #Elixir, #Phoenix, #LiveView, #NodeJS, #TypeScript, #Fastify, #Express and #Python ; and on the DevOps side in CI/CD pipelines (either #GithubActions and Gitlab CI/CD), #Docker and a bit of #Kubernetes

I was tasked with a lot of the #innovation happening in my previous company, researching tools, librairies, patterns or general technologies either for our own #DeveloperExperience or for our products

I also wrote a lot of technical and non technical documentation and internal presentations, and even participated in a few meetups. You can read some of my writing on my blog: https://blog.adrianc.eu

You might also have seen me on a few Elixir-related Discord servers, or even Bluesky (@adrianc.eu) and Twitter ; either sharing tech news, helping people, reading in book clubs or just chatting

I’m open to full-time right now, contracting work can be discussed.

I'm looking for any developer position, not only #ElixirLang, even though it represents most of my experience. And if the technology you're using isn't on my resume, give me a chance! I'm a fast learner and I might anyway have studied it in class :P

DM me for more info, like github link, my resume or anything :)

Boosts, responses and DM welcome, of course!

If you're seeing Dependabot PRs on Node projects named "Bump find-my-way and fastify" today and were not already on Fastify v5, be aware you'll need to update your Fastify config/usage (see https://fastify.dev/docs/latest/Guides/Migration-Guide-V5).

The `find-my-way` (indirect for me) update requires Fastify v5 apparently and that broke several projects which weren't on Fastify v5 yet. Luckily (well, intentionally, obv) the breakages were caught by CICD in dev.

Updating the Fastify logger constructor config has allowed the web server to start now. I'm using a parent logger so this meant adding:
`loggerInstance: parentLogger` to the Fastify instantiation, e.g. the last property in:
```
const fastify = Fastify({
trustProxy: true,
keepAliveTimeout: 3600000,
loggerInstance: parentLogger
});
```
Tests now pass locally, 🤞for the same on Cloud Build!

Dependabot raised a PR against on of my Node projects this morning and the build failed. The PR was to move to Fastify 5 (from 4.x).

I pulled the branch down and sure enough the web server no longer starts. I'd spotted Fastify 5 now requires Node 20+ but I'm already on that.

Time to dig in to the migration guide: https://fastify.dev/docs/latest/Guides/Migration-Guide-V5/

Fastify 5 est officiellement de sortie ! 🎉

Un excellent framework back-end que j'adore toujours autant utiliser. Léger, plein de plugins officiels, avec un rythme d'évolution soutenable et un grand soin apporté à la facilité de mise à jour et à l'expérience de développement.

Гонка за скоростью: сравнение производительности ведущих фреймворков JavaScript в веб-разработке. Fastify, Express, Koa

Недавно я задался вопросом «Какой JS фреймворк самый быстрый». Я обратился с этим запросом в гугл и нашел очевидный ответ «это fastify!». Но почему именно он?. Я практически сразу наткнулся на статью, результаты которой меня немного расстроили, так как в качестве дополнительной нагрузки на endpoint автор использовал вычисление ряда Фибоначчи, что, по моему мнению, не раскрывает всей сути сравнения. Тогда я решил провести собственное исследование.

I'll say the toys I've built with #fastify seem to allow for this setup very easily. #remix is slowly adding these features (route centric of course lol, but thats fine) and you can build it more or less with anything. Nice to have it baked in though.

FYI – I’m available for #coaching / #teaching / conference talks / shorter #freelancing gigs (1-2 days at a time)

I’m right now primarily focusing on my own projects but happy to share my experience with others + never wrong to refill the wallet a bit.

#openToWork

[1/2]

I think I've found my #SPA #SSG #SSR holy grail:

- #Preact with no build step (#ESM only)
- HTM for JSX-like syntax
- preact-render-to-string for server-side rendering
- preact-router for all of the routing
- Preact's `hydrate` method

On the server (I use #koa, but #Fastify or #Express work too) routes can either serve

- pre-rendered static markup
- pre-rendered app routes that get hydrated on the client (switching to client-side rendering)
- fully client-side rendered apps

Hop nouveau petit projet pour tester le tout.

@mcollina #npmRelease #fastify (adding hashtags makes it easier to follow, and so far I'm the only one using #npmRelease, would be nice to get some traction for such a one as I would love to find releases from people I don't yet follow here. That and #newNpmModule for any new modules)
