Broken by recent commit to babel? #2

jbcpollak · 2016-02-17T23:50:57Z

Is it just me or does this commit break this library?

https://github.com/babel/babel/pull/3303/files

now I get something like this:

ERROR in ./lib/index.js
Module build failed: TypeError: Falsy value found in plugins
    at /.../node_modules/babel-core/lib/transformation/file/options/option-manager.js:187:15

....

@jbcpollak are you using NPM 2, or 3?

jbcpollak · 2016-02-21T00:49:44Z

Npm 3!

Yeah I think this is an issue with require-relative and npm 3.

akhilshastri · 2016-03-15T14:12:35Z

Hi, I m facing the same issue "TypeError: Falsy value found in plugins", any updates for it..?

developit · 2016-03-15T15:31:57Z

@akhilshastri I have some work locally to fix this, but it's not working yet.

developit · 2016-03-29T15:54:44Z

Anyone having this issue, please try installing modify-babel-preset@beta (2.0.1). Thanks.

crostonj · 2016-04-06T19:02:52Z

Has this been addressed? I am having the same issue.

developit · 2016-04-06T19:09:42Z

@crostonj Have you tried 2.0.1 (npm install modify-babel-preset@beta)?

crostonj · 2016-04-06T19:43:20Z

I installed it before I posted this question and I still get the error. Do I have configure it somehow? I am trying to use it with webpack and get the error when I try to compile the bundle.

developit · 2016-04-06T20:20:05Z

There isn't really configuration, no. Can you paste your call to modifyBabelPreset()?

crostonj · 2016-04-06T20:26:35Z

I guess that is the trick, I am not sure how to integrate it into the webpack.config to build the bundle.

Here is my current config:

var path = require('path');
var webpack = require('webpack');

var schema = require('./src/data/schema.json').data;
var babelRelayPlugin = require('babel-relay-plugin');

module.exports = {
  entry: "./src/main.js",
  output: {
    path: __dirname + "/public",
    filename: "bundle.js"
  },
  module: {
    loaders: [
      { 
          test: /\.js$/, 
          exclude: /node_modules/,
          loader: 'babel-loader',
          query: {
            presets: ['react', 'es2015', 'stage-0'],
            plugins: [
               babelRelayPlugin(schema)
                ]
          }
      }
    ]
  }
};

this is the error I get when I run webpack:

Typically this module is used to create a babel preset that is derived from another babel preset. If you're using it inline, I believe you should be able to do something like this in your webpack.config.babel.js:

import modifyBabelPreset from 'modify-babel-preset';

module.exports = {
  // .. in your babel configuration parameters:
  module: {
    loaders: [
      {
        test: /\.jsx?/,
        exclude: /node_modules/
        loader: 'babel',
        query: {
          plugins: modifyBabelPreset('es2015', {
            // example: reconfigure jsx transform:
            'transform-react-jsx': { pragma: 'h' }
          }).plugins
        }
      },
      // ..etc
    ]
  }
};

crostonj · 2016-04-07T17:06:30Z

Continuing on this today:

var path = require('path');
var webpack = require('webpack');
var modifyBabelPreset = require('modify-babel-preset');
var schema = require('./src/data/schema.json').data;
var babelRelayPlugin = require('babel-relay-plugin');


module.exports = {
    entry: "./src/main.js",
    output: {
        path: __dirname + "/public",
        filename: "bundle.js"
    },
    module: {
        loaders: [{
            test: /\.js$/,
            exclude: /node_modules/,
            loader: 'babel-loader',
            query: {
                presets: ['react', 'es2015', 'stage-0'],
                plugins: [
                    modifyBabelPreset('es2015').plugins,
                    babelRelayPlugin(schema)
                ]
            }
        }]
    }
};

and I get the following error:

developit · 2016-04-07T17:40:46Z

Plugins has to be a flat Array - try this:

var path = require('path');
var webpack = require('webpack');
var modifyBabelPreset = require('modify-babel-preset');
var schema = require('./src/data/schema.json').data;
var babelRelayPlugin = require('babel-relay-plugin');


module.exports = {
    entry: "./src/main.js",
    output: {
        path: __dirname + "/public",
        filename: "bundle.js"
    },
    module: {
        loaders: [{
            test: /\.js$/,
            exclude: /node_modules/,
            loader: 'babel-loader',
            query: {
                presets: ['react', 'es2015', 'stage-0'],
                plugins: [].concat(
                    modifyBabelPreset('es2015').plugins,
                    [
                      babelRelayPlugin(schema)
                    ]
                )
            }
        }]
    }
};

developit · 2016-06-21T01:08:00Z

Closing this since I'm fairly certain it's an issue that arises when plugins that do not exist are referenced. Please re-open if this is still an issue for you!

mykhailo-ivankiv · 2016-07-14T16:19:19Z

Hi. I have the same problem with babelRelayPlugin.
I have tried to use modifyBabelPreset but it do not work at my environment.

node -v = v6.1.0, npm -v = 3.9.0
package.json:

...
"webpack": "^2.1.0-beta.17",
"babel-loader": "^6.2.4",
"babel-relay-plugin": "^0.9.2",
"modify-babel-preset": "^2.0.3",
...

Error

@neformal13 hmm - can you post how you're invoking modify-babel-preset?

adam-26 · 2016-09-26T17:15:51Z

FYI: I found this error also occurs if you have an EMPTY presets: [] array in a preset. I haven't checked to see if the same occurs with an empty plugins:[] array, but I'd avoid having any empty arrays to be safe.

Would be nice if babel could handle this condition :)
