Guys, will a 150kb minified js package for frontend slow my site down? How large is too large for a frontend script?

Hmm, probably not too bad. I like to compare my scripts to jquery which is about 90kb. If you really want to test it though, try using an add-on to throttle your net speed and try it out.

Edit: in chrome you can do it under the network tab of the dev tools.

Oh I forgot to mention, this package won't be the only js I'm using, I'm adding it on top of my custom scripts and other packages

Depends. What does this package give you for 150kb?

@uselesshero multiple variations of interactive charts, though in the meantime I only need the line chart

Are you caching it client-side?
