Je ne sais vraiment pas d'où vient mon code. Je viens de réparer tous les tests unitaires après un mois de développement non tdd.
Existe-t-il un moyen de diagnostiquer cela?
UglifyJs ne prend pas en charge ES6. L'erreur est très probablement la syntaxe abrégée de la méthode. Par exemple:
const obj = {
method() {
// ...
}
};
Quand il voit la parenthèse d'ouverture, il s'attendait à la place à deux points, comme ceci:
const obj = {
method: function() {
// ...
}
};
Existe-t-il un moyen de diagnostiquer cela?
Il vous indique la ligne exacte de votre morceau, alors jetez-y un œil. Dans le message d'erreur que vous avez publié, il est:
[1.350b2d8a46d91e3c0911.chunk.js:20075,15]
^ ^ ^
filename line column
Ensuite, vous pouvez simplement rechercher dans votre projet un identifiant que vous voyez. Si vous ne souhaitez pas rechercher l'ensemble du projet, vous pouvez exécuter webpack avec le --display-chunks drapeau. Cela montrera quels modules sont inclus dans les morceaux respectifs, vous n'avez donc qu'à les examiner.
Au lieu d'avoir à remplacer toute la syntaxe raccourcie, vous pouvez dire à babel de transpiler la syntaxe raccourcie avec le plugin babel transform-es2015-shorthand-properties .
Pour mémoire: les tests unitaires ne trouveront pas de telles erreurs.

L'erreur indique qu'il attend un deux-points plutôt qu'une parenthèse ouvrante, donc le problème concerne probablement la déclaration d'une fonction comme celle-ci:
var foo = {
bar() {
console.log('Something');
}
}
et cela devra être changé en
var foo = {
bar: function() {
console.log('Something');
}
}
Modification des préréglages de es2015 à env dans .babelrc l'a corrigé pour moi. Babel a changé babel-preset-es2015 en babel-preset-env. Consultez ce lien - http://babeljs.io/env
{
"presets": [
- "es2015",
+ "env",
"react"
],
}
