Hi,
I've run into an issue where my templates.js has bad syntax when i use brunch b -m.

I have a file called templates.js which is my generated jade templates, and if I call uglify on this, it minifies fine (with the default settings)...

Is brunch doing something different that would cause this behavior to be different?

The un-compressed templates file is here: https://dl.dropbox.com/u/120257/templates.js

Cheers,
Chris

I tried the following, but my copyright notice is always stripped in the minified app.js.

In application.coffee I tried adding ! and @license to the comment:

###!
@license app.js
Copyright 2014 blah...
###

In brunch-config.coffee I tried the following options:

exports.config:
  plugins:
    uglify:
      comments: 'all'
      preamble: '# hello'

Getting below error for below code:

CBM-Demo>brunch build --production
31 Jul 22:02:37 - error: JS minification failed on www/js/app.js: Unexpected token: operator (>) (line: 216, col: 64, pos: 5307)

code sample

ages[0] = _.chain(source).map('age1').map(x => { return parseInt(x) }).filter(x => { return !isNaN(x) && x > 0; }).value();
ages[1] = _.chain(source).map('age2').map(x => { return parseInt(x) }).filter(x => { return !isNaN(x) && x > 0; }).value();

Strangely, the prepublish script did not run when I just did git release 1.7.3. I subsequently did npm run-script prepublish, but I downloaded the latest version of the module from the npm registry and saw that the compiled lib/index.js was an old version. I then did npm publish --force to correct this.

This may have impacted other prior releases as well. I'm not quite sure which version of the compiled js I was looking at, but I'm pretty sure it did not include the 1.7.2 changes.

@paulmillr any idea what's going on here?

Hello,

What about supporting ES6, e.g. including uglify-es?

This would help using other libs that require ES6, e.g. @yaga/leaflet-ng2.

Thanks, JC

I want Uglify to ignore app.js but minify vendor.js and lib.js (app.js will be run through Closure using after-brunch)

However, using config.plugins.uglify.ignored = /app.js/ gives me an error when I do brunch build --production

error checking ignores files to uglify:TypeError: Object {"version":3, "file":"../game/js/app.js", "sources":["app/source1.js", "app/source2.js"], "names":[], "mappings":";;;;;... ...AACA, "sourcesContent":["....;"]} has no method 'toJSON'

I am using"
uglify-js-brunch v1.7.7
brunch v1.7.13 (I have in fact also installed brunch using npm install -g brunch/brunch which should be a more up to date version?)

Relevant bits of config:

exports.config =
files:
javascripts:
joinTo:
'js/app.js': /^app/
'js/lib.js': /^bower_components/
'js/vendor.js': /^vendor/

plugins:
uglify:
mangle: true
compress: true
ignored: /app.js/

Possible to rename the app.js minifyed like app.min.js ?

It is difficult to use this with angularjs without being able to pass options. For instance with jade you allow some: https://github.com/brunch/jade-brunch/blob/master/src/index.coffee#L18

The main option need to allow uglifyjs to work with angularjs is --no-mangle.

Able to build this project (that uses react-native-web) in dev.

But when I run yarn deploy, I get the entitled error.

Looked around online to no avail...

OK, ran PORT=4000 MIX_ENV=prod mix phx.server and my app was working fine (NOT getting the error from the Phoenix deploy guide).

So any idea why I'm getting 404s for all static assets when I actually deploy? My assumption is because of this build error...

When using uglify-js-brunch with the following configuration (from config.coffee):

exports.config =
  plugins:
    uglify:
      mangle:
        except: [ "require" ]

With the following command line:

brunch build --optimize

I get the following error.

error: JS minify failed on public/javascripts/app.js: TypeError: Cannot assign to read only property 'except' of [object Object]

I'm using node v0.10.5, brunch 1.6.3, and uglify-js-brunch 1.5.1.

Hi,

it seems that Uglify doesn't work very well with D3JS (v3.0) and also with RickShaw.

When uglified there is an error for RickShaw:

"Uncaught TypeError: undefined is not a function "

Best regards

Running brunch build works fine, but when running brunch watch it executes the initial compilation well but when I edit a file and save it brunch throws errors.

When I edit a CSS file I get this error:

After errors I have to rerun brunch watch because it gets killed by the error, although it doesn't make sense because on the next run it crashes again, always.

Any ideas? Thanks!

I've recently upgraded Brunch and related libraries (e.g., uglify-js-brunch) to 1.7.x. When pushing to Heroku, I get the error pasted below. Any clues on how I can go about fixing this?

If I remove uglify-js-brunch from my package.json, then it'll work on Heroku.

Thanks!

This plugin doesn't work correctly under the current Brunch version (at this time, 2.0.2).

I'm new to Brunch, but from some exploration it looks like the plugin API has changed significantly- for example, the args argument being passed to the optimize function is now a promise instead of an object.

Hello,

I'm running into a problem: I recently wanted to compress my JS files so I installed the plugin. Apparently, it's not working for some reason (same thing with brunch-clean-css). Could you please open my eyes on what I am doing wrong, please?

Here is my package.json

{
  "dependencies": {
    "javascript-brunch": "1.7.1",
    "css-brunch": "1.7.0",
    "coffee-script-brunch": "1.8.0",
    "stylus-brunch": "1.8.0",
    "jade-brunch": "1.8.1",
    "uglify-js-brunch": "1.7.7",
    "clean-css-brunch": "1.7.1",
    "coffeelint-brunch": "1.7.0"
  }
}

And my config.coffee:

module.exports.config =
    files:
        javascripts:
            joinTo:
                'javascripts/app.js': /^app/
                'javascripts/vendor.js': /^vendor/
            order:
                # Files in `vendor` directories are compiled before other files
                # even if they aren't specified in order.
                before: [
                    'vendor/scripts/jquery-1.11.0.js'
                    'vendor/scripts/underscore-1.5.2.js'
                    'vendor/scripts/backbone-1.1.0.js'
                    'vendor/scripts/backbone.babysitter.js'
                    'vendor/scripts/backbone.projections.js'
                ]

        stylesheets:
            joinTo: 'stylesheets/app.css'
            order:
                before: ['vendor/styles/normalize.css']
                after: ['vendor/styles/helpers.css']

        templates:
            defaultExtension: 'jade'
            joinTo: 'javascripts/app.js'

    plugins:
        uglify:
            mangle: false
            compress:
                global_defs:
                    DEBUG: false
        cleancss:
            keepSpecialComments: 0
            removeEmpty: true

I think this could come from the fact I'm using Coffee to write JS and Stylus to write CSS (for clean-css' case) but I didn't manage to 1°) be 100% sure it's the reason 2°) found a solution for that.

Thank you in advance!

I followed the instructions present in the README of this repo, but I still can't generate a production ready build. I get the following warning: It looks like you're using a minified copy of the development build of React. When deploying React apps to production, make sure to use the production build which skips development warnings and is faster. See https://fb.me/react-minification for more details.

Here is my entire webpack.config.js

`

};`

When setting optimize = true and sourceMaps = true I'm getting an error

./node_modules/brunch/lib/fs_utils/generate.js:199
          json = optimizedMap.toJSON();

TypeError: Object {"vers.....MAAO,GAGX,MAAO"} has no method 'toJSON'

This is for the latest version: 1.7.6

I made a little plugin to build typescript with brunch (https://www.npmjs.com/package/brunch-typescript). For a personal project, I want build and uglify but I have an error with compression. So strange, because when I execute manually uglify-js, I don't have fail.

'use strict';

exports.config = {
    paths: {
        'public': 'dist',
        'watched': [
            'src'
        ]
    },
    files: {
        javascripts: {
            joinTo: {
                'dest.js': 'my/source.ts'
            }
        },
    },
    plugins: {
        uglify: {
            mangle: true
        }
    }
};

My package.json :

{
    "dependencies": {
        "brunch": "1.8.*",
        "brunch-typescript": "1.5.*",
        "uglify-js-brunch": "1.7.*"
    }
}

Probably it's obvious, but do you have an idea how to accomplish this with this module? Thanks.
