go-echarts-assets is the turn key solution for hosting go-echarts javascript assets.
It can be placed as it is into your server and its gh-pages acts as the default content delivery host when you evaluate go-echarts for web purposes.
i.e.
On page usage
page := components.NewPage()
page.AssetsHost = "https://cdn.jsdelivr.net/npm/echarts@5.4.3/dist/"
On single chart usage
bar := charts.NewBar()
bar.SetGlobalOptions(
charts.WithInitializationOpts(opts.Initialization{
AssetsHost: "https://cdn.jsdelivr.net/npm/echarts@5.4.3/dist/",
}),
)
