React build is so slow that netlify killed the deployment

[airoude]

As the title says. I upgraded react-scripts to v4 and the build time went from ~6min to ~13min. Now netlify kills the deployment. On my local env the build takes ~4min, what can I do to reduce the build. I know the internet is swarming with cra slow builds but none of them are actually helpful.

I’m using

• node: v14.12 (also on Netlify)
• yarn: v1.22.5 (also on Netlify)
• craco/craco: V5.7.0
• typescript: V4.0.2
• react-scripts: v4.0

hey there, sorry to be slow to respond.

I have a few general resources for you as far as optimizing your build goes:

[Support Guide] How long should Netlify builds take?

The only universal answer to this is: it varies. More detail would probably be helpful, right? Below we explain which factors affect the lengths of builds on Netlify One key factor is the site itself. Larger sites will take longer to build than smaller ones, and things like images and video can impact this (if those assets need to be downloaded or processed during build). Another factor is the static site generator (SSG) being used (if any). The performance of SSGs varies widely…

[Support Guide] How can I optimize my Netlify build time?

If you are interested in learning more about how our bots approach building sites, these three articles are a great place to start: How our Build Bots build sites The last major upgrade to our build environment and perhaps least-loved but most useful, how to debug your builds So you might think, it’s great that Netlify builds every commit from my repos…but isn’t that a bit wasteful? The answer is, it depends, but we can at least give you some best practices for limiting waste. Maybe …

one thing we can also do is bump your deploy time up to 30 mins if you have a credit card on file. would that be helpful? that way you can at least deploy for now.
