Super slow about babel-loader

[jamiebuilds]

@jmeas mind trying to compile them without webpack and timing it?

$ npm install -g 6to5
$ { time ( 6to5 src/**/*.js -d dist ) } 2>&1

real 0m0.818s
user 0m0.725s
sys 0m0.070s

but I think it's an inaccurate number...it only picked up some of the files in src for whatever reason.

[jamiebuilds]

Yeah, there's no way that's right. Can you see if you can get a more accurate number?

[jamesplease]

I tried; no dice.

The build becomes basically instant when I don't use the last suggestion in the "Usage" part of the README.

tl;dr, do not default to loading all .js files with 6to5. I'm thinking that each and every module that imports, say, Backbone, will cause the library to be compiled with 6to5, which adds up quickly.

[jamesplease]

So, I thought that the above was the solution, but I'm honestly not too sure. Gonna open for the discussion to continue. Has anyone else had speed issues, or is it just me?

[Couto]

Weird, I've never noticed any slowness, at least significative.

Anyway my computer has been completely broke, so I had to getting it fixed, and I've been accumulating issues as a consequence.
Luckily it should be ready by next saturday, when I will take the time to measure this and check all the other issues.

Sorry for the inconvenience.

The solution is to not build the node modules. #5 resolves it, but it's pretty specific and not configurable (for instance, there's no option to toggle the behavior, nor a way to expand it to, say, bower components).

[jamesplease]

The best solution is probably to use the exclude option:

{test: /\.js$/, exclude: /node_modules/, loader: '6to5-loader'}
