firebase 主机中的数据传输被认为是什么？

Question

What I considerd data transfare in firebase hosting according to docs

Data transfer (GB/month) — The amount of data transferred to end users from our CDN. Every Hosting site is automatically backed by our global CDN at no charge

So is when a user go to my domain and firebase send the user my web site that lets say for the sake of argument has 100mb so each 10 requests will cost me 0.15 usd according the pricing on fire base?

Data transfer $0.15/GB

My current concern that my react build folder has the size of 3mb since it has too many pngs in it … so will I pay for the transfare of this build folder to end client each time a Client call this site?

Yes, you are charged on the data downloaded from CDN/server .

It'll be best to optimise and compress your images to reduce costs and also loading speed.

Some static assets should get cached locally so the next time user loads the site it might load them from cache instead of the server. So it won't be 3 MB always.

You can get rough estimate of the data being loaded in the network tab of browser console.
