README
> [!WARNING]
> Vite's enable minify by default.There for you will see that the parsed size is larger than actual size.This is because the bundle info
> provide by rollup isn't compressed.(If you care about this problem you can choose anothr plugins.)

### 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?)
### Integrated
Integrate this plugin into your rollup/vite tool. The following is a list of exposed APIs.
```ts
// For integrate it as custom analyzer
// Returns the HTML string
declare function renderView(analyzeModule: Module[], options: RenderOptions): Promise
// Create a static living server.
declare function createServer(): CreateServerContext
declare function openBrowser(address: string): void
declare function injectHTMLTag(options: InjectHTMLTagOptions): string
declare class SSE {
private activeStreams
serverEventStream(req: http.IncomingMessage, res: http.ServerResponse): void
sendEvent(event: string, data: string): void
private removeStream
}
// example
const server = createServer()
server.get('/', async (c) => {
let html = await renderView(data, { title: 'Vite Bundle Analyzer', mode: 'parsed' })
c.res.writeHead(200, { 'Content-Type': 'text/html', 'Cache-Control': 'no-cache' })
c.res.write(html)
c.res.end()
})
server.listen(3000)
// If you want set this plugin in rollup output plugins. you should wrapper plugin `generateBundle` by your self.
const { api, generateBundle, ...rest } = analyzer()
const data = []
const myAnalyzerPlugin = {
...reset,
api,
async generateBundle(...args) {
await generateBundle.apply(this, args)
data.push(api.processModule())
}
}
// .... your logic
```
