Hey, author here. I'm very open to ideas to reduce bloat. It's 140 SLOC and ~1.1kb gzipped without lodash/throttle. I considered writing my own throttle, but wanted something more battle-tested.

Does Rollup produce a more efficient bundle in your experience?

[nathancahill]

Not sure why I was downvoted, I think it's a valid point. To prove it, here's the functionality of your library in ES5 with a naive throttle function: https://gist.github.com/nathancahill/f7ea239306737f2075a94de...

Minified (1.49kb) and gzipped (677b).

Whether lodash functions should be used instead of naive functions is up for debate. My opinion is if the lodash functions are 5x the size of the entire library, it's probably best to not include it, or to include it as a build option (if the user's project already includes lodash for example).

No worries, lodash/debounce can be reduced further with babel+webpack plugins.

Assuming the current setup of babel+webpack the difference between your naive version is just ~0.5 kB.

[nathancahill]

Which still doubles the size of the library: ~0.6kb to ~1.1kb. So while it's just half a kilobyte, do that over and over, with nested dependencies and it really adds up.

Just use https://www.npmjs.com/package/lodash.throttle

[Heqx]

Can you point me to an explanation of the differences between the 'lodash.throttle' module and importing 'lodash/throttle'?

[jdd]

lodash.throttle is a standalone zero-dependency package of just the throttle module. The `lodash` package is a collection of modules one of which is `lodash/throttle`.

You can generally get smaller bundles using `lodash/xyz` modules over the `lodash.xyz` packages because of plugins like:

https://github.com/lodash/babel-plugin-lodash

https://github.com/lodash/lodash-webpack-plugin

Though in the future lodash-webpack-plugin may support `lodash.xyz` packages too.

You should get about the same results using a bundler. Perhaps the lodash.throttle package is for reducing `npm install` time or reducing bloat if you check in your node modules?

[nathancahill]

OP is using that already.

[andreasklinger]

rollup can only load the functions of lodash you actually use into your bundle

[tdumitrescu]

So can lodash. That's what the author is doing here by using

  import throttle from 'lodash/throttle';

rather than

  import { throttle } from 'lodash';
