Uglify or Minimify the standard js files

[juliomatcom]

Hello,
Sorry, this is not a real issue, just a concern, what do you suggest to minimify or uglify the js files without the semicolons ? any package or some thing in the comunity?

Thank you

I would stay away from any minification tool or uglify tool that does not ensure correct ASI during its transform. Semicolons are a necessary for those types of tools to work. So the answer is... any of them (that work presumably)!

Personally I would look for one that works well with my build step via browserify e.g. https://github.com/hughsk/uglifyify (not I have not used this or endorse it, but it looks like something I would try out).

Does that answer your question?

Any modern minification tool would suffice. Most today would parse based on
AST. These two are what most would use:

• uglifyjs
• Closure compiler

Is possible to get the original ASI that use javascript engine with some api ?
I would give a try to this libs
There is any mailing list to send or share the results.. a mailing about standard js ?

Thanks

I have not heard of a module or API that lets you patch in directly to V8's ASI capabilities. Googling, I came across http://blog.izs.me/post/2353458699/an-open-letter-to-javascript-leaders-regarding which actually addresses your first question:

Yes, [ASI is] quite safe, and perfectly valid JS that every browser understands. Closure compiler, yuicompressor, packer, and jsmin all can properly minify it. There is no performance impact anywhere.

We have https://github.com/Flet/semistandard for people working on projects that need semicolons for political or style reasons. Not sure if that helps.

If you come up with anything cool that you want to share just open up an issue or hop onto #standard on freenode.

All the popular minification tools will work just fine on code that passes standard. No need to worry.
