Keystone + React: 'import' et 'export' peuvent apparaître uniquement avec 'sourceType: module'

Question

Après la mise à jour des dépendances du projet, j'ai commencé à faire face à l'erreur. Browserify a du mal à analyser mon code JS, qui est écrit en ES6. Browserify semble s'attendre à ES5.

Je ne comprends pas, pourquoi le sourceType: module semble être le problème ici.

Source:

var babelify = require('babelify'); 
var browserify = require('browserify-middleware'); 
var keystone = require('keystone'); 
var importRoutes = keystone.importer(__dirname); 

// Setup Route Bindings 
exports = module.exports = function(app) { 

    app.use('/js', browserify('./client/scripts', { 
     transform: [babelify.configure({ 
      extensions: ['es6'], 
      plugins: ['object-assign'] 
     })] 
    })); 

}; 

La même chose se produit, lorsque l'omission babelify du code ci-dessus:

var browserify = require('browserify-middleware'); 
var keystone = require('keystone'); 
var importRoutes = keystone.importer(__dirname); 

// Setup Route Bindings 
exports = module.exports = function(app) { 

    app.use('/js', browserify('./client/scripts')); 

}; 

console serveur:

Le problème était d'une valeur incorrecte dans extensions: ['es6'], ce qui était nécessaire était de mettre le réel sion des fichiers JS extensions: ['.js'].

Le code de travail:

var babelify = require('babelify'); 
var browserify = require('browserify-middleware'); 
var keystone = require('keystone'); 
var importRoutes = keystone.importer(__dirname); 

// Setup Route Bindings 
exports = module.exports = function(app) { 

    app.use('/js', browserify('./client/scripts', { 
     transform: [babelify.configure({ 
      extensions: ['.js'], 
      plugins: ['object-assign'] 
     })] 
    })); 

};
