feat: update to `uglify-es` #63

Hartorn · 2017-06-30T00:06:32Z

@michael-ciniawsky @hulkish @graingert : Here is the new PR.

This PR is about moving to uglify-es (following of #55, due to messy chained rebase/push-force, etc...)

Here is a quick sum up of the modifications, please ask for precisions if needed.

Uglify now expose a single high level function minify(code, options), which go through all the steps of minification (parse, compress, mangle, output)
it does not throw errors anymore, ~~so the try-catch is not needed (test if there is an error key in the return of the function)~~
it is possible to get the warnings in the result also, so it is not needed anymore to mingle with AST_NODE warn_function
it is possible to give a filter for comments, so we can hook on that for exporting comments
it is possible to give a preamble in the output, ~~so we can use that for the banner thing (License file, comments, ...)~~

Basically, we do not need to use any other function than minify from uglify, it is mainly about giving proper options, handle the source maps and output.

I did not had time to update the docs, I will do in the next days.

TODO :

[ ] Update the documentation
[ ] Add new test for the new functionnalities

# Conflicts: # src/index.js

…class

# Conflicts: # package.json

… eslint

* Putting back try-catch (wrong asset handling) * Adding banner for comments after being sure comments are presents * Correcting filter extraction * Correcting error handling

@hulkish Honestly, I'm not so familiar with unit testing like this. I corrected the existing ones (only the configuration given to the plugin). I might need help on this, if anyone wants to lend a hand :)

michael-ciniawsky · 2017-06-30T00:27:33Z

I take care of the docs in #61 after this PR :)

cc @hulkish for Unit testing

hulkish · 2017-06-30T00:34:30Z

@Hartorn sure, you wanna give me access to your fork and ill add the test.

hulkish · 2017-06-30T00:43:16Z

@Hartorn Nvm, I see you've already included your updates to the tests: https://github.com/webpack-contrib/uglifyjs-webpack-plugin/pull/63/files

This looks good to me, 👍 🌮

Hartorn · 2017-06-30T00:48:09Z

@hulkish @michael-ciniawsky Already invited you both to my fork, maybe it will be useful.

I pushed the modifications to the package-lock, did not pay attention the repo was in npm 5.
Build should be all good

@hulkish I thought you were talking about adding new cases for uglify-es options.
I might still need to add a check on source map (the one inside uglifyOptions must be ignored, we only care about the one in options).
Thanks for checking :) 👍

We need to find a way to avoid the options nesting

test/all-options.test.js

@@ -33,6 +27,14 @@ describe('when applied with all options', () => {
          return `License information can be found in ${licenseFile}`;
        },
      },
+      uglifyOptions: {


Possible to keep the individual options in the top level e.g via filter() ?

I felt like they were too many options to keep them at top level. (https://github.com/mishoo/UglifyJS2/tree/harmony#minify-options-structure)
That way, I thought it was easier to understand what's coming from the plugin, or what's coming from UglifyJs, and so easier to read the docs according to the need.

hmm.. I basically agree 😛, but uglifyOptions is too verbose (but no better idea atm, just complaining :D). What's your opinion on removing warningFilters && extractComments ? 🙃 What is especially the usecase for warningFilters?

warningFilters : I think it can be used by some people to filter for example on node_modules and still see warnings about their code, maybe to check dead code presence, or optimisation.

extractComment: It is for copyright/license reason I think => that way, the file you load is still small, plus a preamble redirecting to another file containing all the copyrights/licenses.

src/index.js

+      parse: parse || {},
+      compress: compress || {},
+      // eslint-disable-next-line no-undefined
+      mangle: mangle === undefined || mangle === null ? true : mangle,


mangle == null is idiomatic

@graingert I don't understand this. What you mean is that I should not test mangle === null but only mangle === undefined ? true : mangle ?

mangle === undefined || mangle === null is the same as mangle == null

Thks for the explanation.

michael-ciniawsky · 2017-06-30T01:11:43Z

What are the uglifyOptions defaults atm => new UglifyJSPlugin() ?

⚠️ Please wait with the next beta release I quickly finish the docs PR :)

joshwiens · 2017-07-06T03:06:36Z

@jdalton @graingert ...

joshwiens · 2017-07-06T03:11:42Z

For all involved, this is staying on a beta tag at minimum, until the test suite is reliable. I personally wouldn't have merged this yet given Tobias should have looked at it & we didn't answer the performance question though I do understand everyones desire to get this in master.

@Hartorn - Please see my comment in #67

The latest version of striptags is causing the build task to fail because it uses ES6, which is not supported by the version of Uglify that Webpack is using. As soon as [1] is published to a main release and Webpack updates to use that release, we should be able to upgrade striptags to the latest version. [1] webpack-contrib/uglifyjs-webpack-plugin#63

See webpack-contrib/uglifyjs-webpack-plugin#63 and https://github.com/mishoo/UglifyJS2/tree/harmony for more information about this. Fix angular#7532

openjck · 2018-02-23T01:42:37Z

This hasn't been released yet, has it?

edit: Apologies. Answered my own question. Yes, it has been released.
