TypeError: Impossible de lire la propriété «webpackJsonp» de non défini

J'ai une application React (app A), créée il y a environ 2 ans à l'aide de create-react-app, et elle est éjectée. L'application est exportée en tant que module commonjs2 et expédiée dans un package NPM, pour être utilisée dans un projet next.js (application B).

Tout s'est bien passé jusqu'à ce que je mette à jour certains packages dans l'application A, qui contiennent des composants génériques que nous utilisons. L'erreur lors de l'importation dans l'application B était que la fenêtre n'était pas définie, probablement en raison de SSR.

J'ai résolu cela dans la configuration du webpack de l'application A en utilisant globalObject: 'this'.

Maintenant, lorsque j'essaie d'importer l'application A dans l'application B, le message d'erreur est:

TypeError: Cannot read property 'webpackJsonp' of undefined

Je suppose que quelque part quelque chose essaie d'appeler window['webpackJsonp']?

J'ai déjà essayé de modifier le webpackJsonpFunction, mais comme prévu, il essaiera simplement d'obtenir une propriété différente de undefined.

Toute aide serait grandement appréciée!

Géré pour résoudre ce problème. Le problème était que, après une mise à jour de certaines dépendances dans l'application A, webpack créait des morceaux à charger de manière asynchrone à l'aide de jsonp, spécifiquement pour la date-fnsdépendance.

La solution était dans la configuration du webpack:

target: 'node'

Cible par défaut web, permettant ainsi la création de blocs asynchrones.

De plus, j'ai également dû utiliser LimitChunkCountPluginpour empêcher le webpack de créer des morceaux.

plugins: [
    new webpack.optimize.LimitChunkCountPlugin({
        maxChunks: 1
    })
]
