Refactoring, env, closing a bunch of issues #53

Comments are too length and extra. Code is pretty self-explanatory.

Maybe better to leave a link to related issues? Just an reminder why this code shouldn't be removed.

Yeah, please do.

Extensions? Parent dirs?

Yeah, thought about it.

I don't want to duplicate whole resolution logic from Babel. Maybe we could reuse it somehow?

Not sure, it is not in the public API afaik, but it may be worth exposing.

However, I don't see it blocking from merging this PR. Some time later.

I'm gonna dig a bit in Babel's sources. I'll keep you updated.

@shvaikalesh here's a little bit complex resolution. What do you think?

loganfsmyth · 2017-03-10T19:03:25Z

Generally I think the Babel team as a whole has mixed feelings about enabling plugins/presets by default like this FYI, but it seems like that has already been released as a feature, right?

Given that, the currently-used approach (in babel-loader and babel-register) to resolving the config is the following:

const OptionManager = require('babel-core').OptionManager;

const opts = new OptionManager().init({
    // whatever options you'd pass to Babel normally.
});

// Check both, not just `plugins`.
const hasConfig = 
  (opts.plugins && opts.plugins.length > 0) ||
  (opts.presets && opts.presets.length > 0);

if (!hasConfig) {

}

It's an ugly API but please do not try to hardcode this. If we fix bugs or add new config methods like the newly-landed for 7.x .babelrc.js, your code will just break again.

denysdovhan · 2017-03-11T10:36:17Z

@shvaikalesh reasonable notice from Babel's Slack:

Actually, this PR could be easily resolved by removing these lines:

-if (!opts.presets) {
-     opts.presets = ['latest'];
-     // ['env', opts.env]
-}

Unfortunately, it would break backward compat.

paulmillr · 2017-03-11T12:07:29Z

I don't understand why "having defaults" is a bad idea. Brunch is all about simplicity and no bullshit. We don't want users to write configs when the program can think for them instead.

denysdovhan · 2017-03-11T13:35:02Z

@paulmillr okay. Anyway, I'm gonna find a better solutions. Will update my PR soon.

@loganfsmyth don't we run the risk using some kind of internal APIs? Probably, you would like to change Babel's internal API and then we will find ourselves in the situation when our users get broken builds.

loganfsmyth · 2017-03-11T18:54:32Z

don't we run the risk using some kind of internal APIs? Probably, you would like to change Babel's internal API and then we will find ourselves in the situation when our users get broken builds.

I'm not sure what you mean? The point of the OptionManager API is to get just the data you're asking about.

shvaikalesh · 2017-03-12T03:17:28Z

Agreed with Paul here. We should have cool defaults, like babel-preset-env. Related: #54

denysdovhan · 2017-03-13T08:54:39Z

I'm not sure what you mean?

@loganfsmyth OptionManager is an internal API, isn't it? That means you wouldn't warn us when you change that API.

loganfsmyth · 2017-03-13T09:02:20Z

It definitely won't break in 6.x and I'm planning to specifically leave a dummy class of export class OptionManager { init(opts){ ...call internal api... } } in 7.x for backward-compatibility because we want the transition from 6.x to 7.x to be as seamless as possible for people.

It's used by babel-register and babel-loader, which are both independent of babel-core, so any change to it at this point would also break those, which is a no-go for us.

why return Assertion to mocha?

Does Mocha care about what is returned?

Anyway, yeah, that's not a good practice. Gonna add curly brackets around it.

denysdovhan · 2017-03-26T15:12:44Z

Now babel-brunch uses env, detects UglifyJS and sets corresponding target if it's needed. At this point, it should be enough to fix #52, #54 and #41.

@shvaikalesh @paulmillr what do you think about targets options for babel-brunch proposed by @yavorsky? (#53 (comment))

require('uglify-js-brunch')

JS is not Ruby. 0 is falsy.

JS is not Ruby. 0 is falsy.

Correct me if I'm wrong, and it's not immediately clear, but this should work because @denysdovhan is checking length > 0.

I suggest wrapping the comparison check in parens so it is more obvious that you're using a comparison operator.

const hasConfig = babelConfig.presets && (babelConfig.presets.length > 0) || babelConfig.plugins && (babelConfig.plugins.length > 0);

@millerized @shvaikalesh is right. Doesn't matter. This should work too:

const hasConfig = babelConfig.presets && babelConfig.presets.length || babelConfig.plugins && babelConfig.plugins.length;

millerized · 2017-03-29T02:40:41Z

Hi @denysdovhan. I would offer to help contribute and get this past the finish line, but it looks like you are almost there.

I am looking forward to using brunch with env support – great work! 🍻
