Intro

Babel is a tool that helps you write code in the latest version of JavaScript. When your supported environments don't support certain features natively, Babel will help you compile those features down to a supported version.

In

// ES2020 nullish coalescing
function greet(input) {
  return input ?? "Hello world";
}

Out

function greet(input) {
  return input != null ? input : "Hello world";
}

Try it out at our REPL.

broccoli-babel-transpiler's Issues

Virus threat detected in one of babel-core files

Hi,

I am running an ubuntu machine with COMODO Antivirus installed. I have working on a project written in EmberJS using ember-cli and facing an issue: the antivirus program has detected 2 threats in following files:
EMBER_PROJECT/node_modules/ember-cli-babel/node_modules/broccoli-babel-transpiler/node_modules/babel-core/node_modules/core-js/modules/core.log.js

EMBER_PROJECT/node_modules/ember-cli-babel/node_modules/broccoli-babel-transpiler/node_modules/babel-core/node_modules/core-js/library/modules/core.log.js

Further description I am getting is: "Heur.Dual.Extensions"

Any idea what is going on here?
Thanks in advance
Pavol

Unknown option: direct.presets

I'm attempting to use it like so:

const babel = require('broccoli-babel-transpiler');
const apps = babel('src', {
    presets: [ 'react', 'es2015' ]
});

And am seeing the following error:

ReferenceError: [BABEL] Foo.js: Unknown option: direct.presets
    at Logger.error (C:\inetpub\wwwroot\MyProject\node_modules\broccoli-babel-transpiler\node_modules\babel-core\lib\transformation\file\logger.js:58:11)

    at initializePromise (C:\inetpub\wwwroot\MyProject\node_modules\rsvp\dist\rsvp.js:588:5)

Ideally, I'd like to reuse my .babelrc file which happens to contain presets information, but this plugin fails on that as well (with a similar error, Unknown option: .babelrc.presets). So this seems like a reasonable step in that direction.

seemingly pointless try/catch

Use absolute path while importing own modules

So we can use import config from 'config' in every file in every directory inside app/webroot/es6/.

// ember-cli-build.js
var browserify = require('broccoli-browserify')
var babelTranspiler = require('broccoli-babel-transpiler')

module.exports = function() {

  // Watch the tree with babel
  var js = babelTranspiler('app', {
    filterExtensions: ['js']
  });

  // Convert it to ES5
  js = browserify(js, {
    entries: [
      './webroot/es6/main.js'
    ],
    outputFile: 'js/app.js'
  });

  ...

}

Confusing error message for non-parallelizable plugin

Babel accepts plugins as (among other things) either a string denoting a module to require, or a tuple containing that string and optionally some configuration for that plugin. It will also accept a singleton array with just the module path as a sort of degenerate version of the second case, i.e.

plugins: [
  '/path/to/some/plugin.js',
  ['/path/to/some/plugin.js', { config: true }],
  ['/path/to/some/plugin.js']
]

For the third entry, the parallelization logic interprets that plugin as ['/path/to/some/plugin.js', undefined], and since undefined isn't JSON-serializable, the plugin is considered unparallelizable. That's easy enough to work around, but the error message we got with throwUnlessParallelizable turned on looked like:

[broccoli-persistent-filter:Babel > [Babel: ember-data]: Babel: ember-data] was configured to `throwUnlessParallelizable` and was unable to parallelize a plugin.
plugins:
1: name: unknown, location: unknown

If the relevant plugin path had been included in that output, it would have helped with tracking down the source of the problem.

.babelrc changes do not bust cache

When using a .babelrc (or similar) config file for babel, changes to this file to not bust the persistent cache, causing compiled outputs to not change.

Not sure the best way to handle this as https://babeljs.io/docs/en/config-files lists various techniques babel goes through to find config file, but it could be as simple as including their hash in the cache key.

Option to turn off extension stripping on the moduleId

The latest versions of es6-module-loader and SystemJS ave stopped adding .js on to module names and paths without extensions. The Broccoli plugin does this:

if (options.moduleId === true) {
    options.moduleId = replaceExtensions(this.extensionsRegex, options.filename);
  }

Which strips the extension from the filename. An option to turn off that stripping might be handy given the current state of popular loaders.

There is a way of fixing it if you only have one known extension to deal with via Babel's getModuleId function which broccoli-babel-transpiler will pass through to Babel's transform function if set This worked for me, but is only useable when you are not transpiling a tree with a mix of extensions.

var moduleTree = babelTranspiler(es6Tree, {
    sourceMap: 'inline'
    ,modules: 'system'
    ,moduleIds: true
    ,moduleId: true
    ,getModuleId: function (name) {
        return name+".js";
    }
});

Module names "unknown"

This compiles es6 files fine, but I can't figure out how to actually use the files in an app. My thought was to require the main module manually, as an entry point into the compiled code. However I couldn't figure out what it was named. I thought it would be the relative file path of the file, but it did not seem to be that.

Also I noticed that if I enable the amdModuleIds option in 6to5, it says "unknown" for all of the module IDs.

define("unknown", ["exports"], function (exports) {
    // etc.
});

Update to latest babel

So according to the npm message, 5.3.0 is much faster, so if we can could we use that here?

Example Project

hey,

I've been having a hard time getting a workflow for getting my code to incrementally transpile from es6 to es5. I can get gulp or grunt to work but not very cleanly, I can't find any example projects that work as is.

For example on this homepage you have this example code:

var esTranspiler = require('broccoli-babel-transpiler');
var scriptTree = esTranspiler(inputTree, options);

What does inputTree have to be? I'm finding broccoli documentation in general obtuse or when not to be geared more towards front end devs. I'm building a purely atom-shell (now electron) app.

Could someone point me to an example app that does takes a src folder and transpiles it using this module to a lib folder. Ideally with it rebuilding things as I change them. I assume that's how broccoli serve is supposed to work.

Any help would be appreciated,
Francois

Version 6.1.4 not tagged "latest" on npm

Perhaps this is intentional, in which case please close this, but I just ran "npm install --save broccoli-babel-transpiler" and ended up being surprised that it installed version 5.7.4, rather than 6.1.4.

$ npm dist-tag ls broccoli-babel-transpiler
latest: 5.7.4
next: 7.0.0-beta.2
old: 5.5.1

sourceMap idea

the YPT guys @caridy and @ericf may want to chime in.

i believe the two approaches are likely:

• by convention expect a sibling .map file: mmun/broccoli-es6-module-transpiler@72985d1
• generate inline source maps

I like the last one the best, as it prevents the dual file path.

Would love to hear your thoughts.

Babel options "only" and "ignore" are not respected

Babel accepts an array of glob or regex of paths for only, but those options do not appear to be respected when passed to the plugin.

module.exports = require('broccoli-babel-transpiler')('src', {
  browserPolyfill: true,

If I remove that option, everything builds just fine, but doesn't run in the browser (require is undefined).

Use filter that provides stable outputPaths

We need to update this to use https://github.com/caitp/cauliflower-filter so that the output paths are consistent.

we need to likely add this feature (or make it tested upstream)

This is likely due to the fact that Babel 7's options validate before running. The workers needed to be pooled based on Babel version.

tests fail on recent versions of babel -

Inline source map issue

Hi. Sorry if this is a dumb question, but how do I get the sourcemaps to appear? Currently I have:

var appJs = esTranspiler(appTree, {
  sourceMap: 'inline'
});

but this doesn't work even though sourcemap is the only valid option name I've found. sourceMap: true doesn't work either. It's doing everything else fine.

fails without options.filename

Imports conflict with local variables

I'm using Ember CLI, with ember-cli-babel which in turn uses this addon. This may want to be opened as an issue in babel itself?

I have the following in my app:

import {
  updateMeeting
} from 'minutebase/use-cases/meeting';

export function setupAgenda(meeting) {
  return updateMeeting(meeting);
};

Which appears to be being transpiled to:

define('minutebase/use-cases/agenda', ['exports', 'ember', 'minutebase/use-cases/meeting'], function (exports, Ember, meeting) {
  'use strict';

  exports.setupAgenda = setupAgenda;

  function setupAgenda(meeting) {
    return meeting.updateMeeting(meeting);
  }
});

Notice that there's an imported meeting and a local meeting which tramples on it so meeting.updateMeeting is undefined.

browserPolyfill option does not work

I was trying the option browserPolyfill option but it does not work but when i write my own logic in my Brocfile.js to merge the browser-polyfill.js file it works as expected.

Picked the logic to copy file from here: https://hacks.mozilla.org/2015/06/es6-in-depth-babel-and-broccoli/

code:

babelCorePath = require.resolve('broccoli-babel-transpiler');

babelCorePath = babelCorePath.replace('index.js', 'node_modules/babel-core/');

var projFiles = babel('src', {
    filterExtensions: [ 'es6'],
    browserPolyfill: true
});

var babelCoreTree = funnel(babelCorePath, {
    files: ['browser-polyfill.js']
});

projFiles = mergeTrees([projFiles, babelCoreTree]);

out-dated link in the description

"Broccoli plugin transpile ES6 to readable ES5 https://github.com/very-geek/broccoli-6to5-transpiler"

only the owner can update this.

Question: alpha state?

Hey 👋

The last alpha was released on the 5th of Jan.
I am waiting for an update of babel core, because of a vulnerability.
Could you give me an update please?

Thanks 🙂

Polyfill missing in output due to bad path handling

In the lines quoted here, the plugin constructs a path to @babel/core in order to fetch the browser polyfill into the broccoli pipeline:

broccoli-babel-transpiler/index.js

Lines 64 to 65 in 7c4a334

	var babelCorePath = require.resolve('@babel/core');
	babelCorePath = babelCorePath.replace(/\/babel-core\/.*$/, '/babel-core');

On one of my development systems, this fails because npm installs @babel/core into ./node_modules/@babel/core; as a result, the path returned by require.resolve() no longer matches /\/babel-core\/.*$/ -- and my other development system is a Windows 10 machine, where require.resolve() returns a path separated with backslashes.

Improve parallel errors further

fix: a plugin of the form: [serializable, nonSerializable] will incorrectly display serializable as the problem, not nonSerializable

save usedHelpers meta

Save the babel meta to a json file so that a babel helpers module can be compiled later. Maybe even add an import babelHelpers from 'babel-helpers'; in a source map friendly way so that a helpers module can be built when the app is packaged.

Importing relative modules

Hi,
I currently have a simple setup to transpile multiple files into a single file inside a folder (pretty common 💃 ). Everything works well, except when I try to import a file into another one, and the compiled file get's messed up since it is still referencing to the relative path instead of having it imported and transpiled.

Someone knows a way to fix this?
Thanks!

Can't supply sourcemap source file name

It looks like the plugin is setting the sourcemap source file name to the relative path, with no ability to customize that.

It would be nice if we could supply our own function in the options hash that would return the sourcemap source file name. In my use case, I've got several nodes that were funneled down to some subtree of the original source, and then compiled, but I can reconstruct the correct source file prefix at design-time.

Happy to submit a PR, but wanted to test the waters in case I was missing something first.

Is Node 0.12 still supported in v5.x?

If yes, then broccoli-persistent-filter -> async-disk-cache ^1.2.1 -> username ^2.3.0 breaks Node 0.12 compatibility.

Drilling down, the problem is caused by babel-runtime not having a "main" key in its package.json. In "babel-code-frame/lib/index.js" we have:

var _interopRequireDefault = require("babel-runtime/helpers/interop-require-default")["default"];

... so we shouldn't have to have the "main" key. This seems like a weakness in hash-for-dep depending on node-resolve which requires a "main" file. This seems to have nothing to do with babel-6 per se. I'll look into reporting and patching downstream (it would seem that resolve takes a filter... hash-for-dep is just using the "main" file to hash it and not actually load it, so we could insert a fake main if package.json is read but is missing "main").

I thought I'd report here in case someone who actually understands the code has a better idea. This seems like something that would break quite often actually, so I'm wondering if I'm overlooking something.

Update babel-7 branch with latest changes on master.

cache corruption side channels: plugins needs to be taken into account when deriving cache keys

1. hashForDep https://github.com/stefanpenner/hash-for-dep of the given plugin (if its an NPM package) this should become part of the plugin subclasses cache key
2. per transform cache key, basically (ideally) the result of options we pass to babel and the babel plugin on each transform.

Some Side-channel examples: hbs-template-compilter provides a template + defeaturify step provides features.json

warn/error if duplicate plugins provided

ember-engines/ember-engines#596 leads me to believe we should try and detect this failure mode and warn asap...

cache not documented (or disable-able)?

I was having an issue with imports in index.js

givanse/broccoli-babel-examples#4

and found that resolveModuleSource wasn't being called. When I upgraded this package from 5.4.5 to 5.5.0, I found that resolveModuleSource was called... once. However, before I could do any debugging it stopped working again. Incidentally, I fiddled with another option and got resolveModuleSource to run again. I am guessing that it is caching values in global location (hmm... perhaps ~/.babel.json?)

However, this isn't documented anywhere I can find, nor can I find out how to turn off global cache so I can debug resolveModuleSource. Probably I will be able to continue flipping irrelevant switches to invalidate cache and debug enough to fix my problem, but this seems a suboptimal solution.
