It is!! I think we can shave off at least 60h of ci per month 💸

And it's not a "simple" vite repo, in that repo we have:
- @astro.build
- @storybook.js.org with @vitest.dev addon
- @vitest.dev with browser mode, and unit mode
- And a couple of vite frontend apps

Well done to the Rolldown team! 👏

Nicolas Beaussart @beaussan.io · 16d

Like every couple of weeks, I try @rolldown.rs @vite.dev on PayFit's frontend codebase, but this time, it's all green 🎉

And the stats are pretty impressive, from 2m builds down to 8s ! All of that, with nearly no config change (just a polyfill plugin). Maybe it's time to run it in prod 🎉

There is a hidden rule in Cobol that says, if you are called Nicolas, then you must be good with legacy codebases :p

I've loved the digital edition, but I always like a physical editions of the books I've enjoyed a lot!

If you have to deal with legacy codebase, this book is full of actionable and useful tips!

Thanks a lot @nicoespeon.com for writing this!

Isaac is an awesome person, very knowledgeable and now, on the market! If you run large monorepos, or codebases in general, I'm sure he will be able to help you out!

Isaac Mann @mannisaac.bsky.social · Aug 11

I'm offering free 30 minute @nx.dev configuration assessments! DM me with details about your repo and I'll send you a scheduling link.

Last week, I was laid off by Nx, so I get to do what I enjoy doing for now. I'll keep going until I don't want to any more.

Nicolas Beaussart @beaussan.io · Aug 10

Is there a tool to help you find such costly imports within a codebase?

Nicolas Beaussart @beaussan.io · Aug 9

I wanted to use the oxc prettier plugin at work, with also this plugin, I guess I'll prepare a troubleshooting guides for that 😅

Thanks for finding this!

- Nx sync nx.dev/concepts/syn...
- Nx conformance nx.dev/blog/nx-clou...
- And Nx polygraph to help us untangle our poly monorepo 😅 nx.dev/ci/recipes/e...

I can go in depth in any of the features if you need! :D

Turborepo is great, but scaling a monorepo requires more from my experience

Sync Generators

Learn how to use Nx sync generators to maintain repository state and update configuration files based on the project graph before tasks are run.

Nicolas Beaussart @beaussan.io · Jul 25

Overall, there is a feature overlap between the two, but for me, what is key differences:
- nx agents nx.dev/ci/features/...
- nx task inference that allows us to centralise and distirbute tasks configurations nx.dev/concepts/inf...
- Generators and executors nx.dev/blog/tailori...

Distribute Task Execution (Nx Agents)

Learn how to use Nx Agents to distribute task execution across multiple machines, optimizing CI pipeline speed and efficiency through intelligent task allocation.

Nicolas Beaussart @beaussan.io · Jul 25

And a looooot of change management to merge all repo into one big frontend monorepo 😅

Nicolas Beaussart @beaussan.io · Jul 25

And the rest was uniforming the stack (from 6 -> 1 bundler), tooling, configs so that caching can be configured the same way across each library within the mono

Nicolas Beaussart @beaussan.io · Jul 25

The articles stays high level, since it's based on the interview that was high level 😅

Few things that helped a lot:
- Splitting tasks across runners on nx agents saved us around 1h on ci
- nx cloud caching is saving us around 100 days of ci monthly

Nicolas Beaussart @beaussan.io · Jul 24

And that 2h was from last October!

Now we are at 20 minutes from branch pushed to deployed!

Including merge, dev, staging, e2e and prod deployment 😍

Nx @nx.dev · Jul 24

PayFit achieved incredible results with a strategic approach to introducing monorepos in their organization.

✅ 5 days → 2 hours deployment time
✅ 75% faster coding
✅ 100% of teams now want to migrate back
