NextJS Webpack Version 5 Build Error

[someyoungideas]

I am currently using NextJS with this webpack plugin within the next.config.js. When I attempt to update to use webpack version 5 with NextJS I get the following build error.

(node:74857) UnhandledPromiseRejectionWarning: Error: Entry pages/_app depends on /Users/redacted/Projects/nextjs-antddayjs-webpack5/node_modules/antd-dayjs-webpack-plugin/src/init-dayjs-webpack-plugin-entry.js, but this entry was not found

I just bumped into the same error.

@iamkun Could you see?

i have same issue in nextjs webpack 5

[FreyrThorv]

👍 Same issue here. Are there any plans to update this plugin to support Webpack 5?

For now it's easy to continue using Webpack 4 but the next major version of NextJS will force users onto Webpack 5. This means users will need to chose between removing this (amazing!) plugin or live with being stuck on version 10 of NextJS.

@someyoungideas @icflorescu @AkramiPro @FreyrThorv Next.js v 11 is able to exclude moment locales, so in my project I just delete this plugin and my bundle size is not increased

Any update on this issue please? I dont want to use moment as it is deprecated.

You can use this solution:

I can confirm that this works. Too bad I spent the time setting up the plugin only to find it not working 😩

Thanks @tientran0019 🙏

If you're using typescript, you can go w/ this (source):

import { Dayjs } from 'dayjs';
import dayjsGenerateConfig from 'rc-picker/lib/generate/dayjs';
import generatePicker from 'antd/lib/date-picker/generatePicker';
import 'antd/lib/date-picker/style/index';

const DatePicker = generatePicker<Dayjs>(dayjsGenerateConfig);

export default DatePicker;

---

Caveat -- if you take the code from antd's own Replace Moment.js section, they're already using ES module imports:

import generatePicker from 'antd/es/date-picker/generatePicker'; vs. import generatePicker from 'antd/lib/date-picker/generatePicker';

import 'antd/es/date-picker/style/index'; vs. import 'antd/lib/date-picker/style/index';

For some reason, these modules aren't transpilable -- not even w/ next-transpile-modules.

So, import from lib instead -- just like in the top example.

This solution does not support localisation...
