// If you are using it in rollup or others support rollup plugin system you can import 'adapter' from package.
// Then use it with adapter(analyzer())

DEBUG

If you're using vite you can get the logs with vite build --debug and then extreact the part relevant to analyze plugin. Or using cross-env to setup ANALYZE_DEBUG=true in your local. env.

Why i get the chunk size is empty?

If you're use a plugin that break the sourcemap it will affect the analyze plugin. I know it's stupid, But is the way to get the size close to the actual size. Like @vitejs/plugin-legacy don't prvide the correctly sourcemap for legacy chunk. For some reason, no analysis will be provided for those module.

Why when i specify analyzerMode as static and set openAnalyzer as false don't create a liviing server?

I don't want to add new option to control living server.

For vite based framework or library!!!

If you're using vitepress or remix or qwik and etc who based on the vite framework. Normally it will run two vite instance during build phase. So you should ensure that analyzerMode as server.(If you pass static or json for the analyzerMode i can't promise the final result.) Like vitpress will remove something (I don't know why? Maybe it's run with race?)
