🤔 What if there were a conference without talks? Just hanging out with OSS maintainers & builders, seeing what they’re working on, and learning cool stuff by actually talking to people. 🤯 What if hallway track turned into the whole event! 💡 @tannerlinsley.com is exploring it. Interested? ⬇️

It was a pleasure to be able to speak and share what I had learnt while reducing the bundle size of AG Grid.

With an Angular app that includes an Angular lib I am seeing different bundle sizes based on changes in the versions used. Lib 17 + app 19 smaller than lib 18 + app 19 But lib 20 + app 20 is significantly smaller than both. No code changes, just package.json Is this expected / known about?

I am in the process of evaluating the changes in React performance between v18 and v19. Prod fairly stable. Dev 19 is significantly slower. I know we should never measure performance in Dev but in reality a lot of developers are doing just that! Has anyone else noticed this?

I used JS private members for a long time, because they are awesome and really private. But I haven't thought about that the bundler can mangle the names, because they are private! All makes sense now... Thank you, @scooper.dev youtu.be/B8qrGmAbJFU

Smart Bear would have failed had I not listened to what customers were really saying. And almost always they were saying it via tech support, not via interviews, not via reviews, not via feature-submission forms. Support == product development

Tech Support is sales

Tech support isn’t just troubleshooting; it’s the face of your company. Which means it’s your brand, your positioning, and when it’s excellent, it is sales.

Does anyone know of a tool that can run over a Typescript code base and suggest possibly unused public methods? What to automate the process of finding unused methods following code changes with the aim of minimal bundle size. (I don't fancy doing find for 500 that are marked public...)

Stephen Cooper @scooper.dev · 30/01/2025

I am relieved to see this view point expressed from a testing authority as this is what we have started telling people in support. I can't imagine the time that has been lost to unexpected test failures, especially when "it works fine in my browser" www.epicweb.dev/why-i-won-t-...

I spent yesterday converting a load of AG Grid Angular examples to use signals. I love the DX and how easy it has become to enable OnPush with confidence. computed - the way you can just use signals and let Angular take care of the dependency updates is 🔥! Good work @angular.dev team!

Some excellent additional information concerning ref callbacks

Stephen Cooper @scooper.dev · 05/12/2024

Is this a trade off for speed of build times with esbuild becoming the default in v19? Or is this offset by people using deferable components and hydration?

110

Stephen Cooper @scooper.dev · 03/12/2024

Anyone experienced a different bundle size output with the new Angular esbuild builder as opposed to the webpack one? Validating an Angular 19 app importing AG Grid and get very different bundle size outputs. Looks like a difference in tree shaking capabilities.

Busy writing codemods for the next major release of AG Grid so that we can land some of the biggest changes in a major yet. And when I say biggest, these changes will enable some of the smallest bundle sizes yet. Looking like a possible 40% reduction based on the features actually used!

Today I learnt that @vuejs.org can, (what feels like magic) take a Typescript interface and turn that into property coercions for a component's properties! I had to double check it, I hadn't seen this before as part of a framework, User Types -> Actual Code

Being able to test types is such a great feature, especially within library development.

There are such pros and cons working exclusively on library code. Pro - you get to go deep on optimisations and it's justified Con - you can't always be sure you aren't going to break some users
