Redoc does not work with nextjs

[tm1000]

Between release 53 and 54. Redoc suddenly broken with any system that is using webpack 5 and nextjs (v2.0.0-rc.53...v2.0.0-rc.54)

See:

• ModuleNotFoundError: Module not found: Error: Can't resolve 'core-js/es/promise' in '/Users/me/project/node_modules/redoc/bundles' #1645
• upgrade breaks redoc from 2.0.0-rc.48 to 2.0.0-rc.51 #1575

It looks like redoc is including webpack and perhaps being bundled twice. The "standalone" version of Redoc (used in React) should not be bundled/compiled. The bundling should be left to upstream. What appears to be happening is that the bundle is assuming "WEB" only while nextjs is both NODE and WEB

I was just about to open exactly the same ticket!

@tremby you can sort of fix with with a NextJS Webpack5 workaround:

Im not sure of the implications of doing so

For my specific usage I had to do this (next.config.js):

const settings = {
	webpack(config, options) {
		if (config.resolve.fallback) {
			config.resolve.fallback.fs = false;
		}

		return config;
	},
};
settings.future = {
	webpack5: true,
};

module.exports = settings;

What's strange is that redoc is already doing this:

redoc/webpack.config.ts

Line 50 in c09cf9d

fs: false,

Thanks. But I'm still using webpack 4 for now, and have worked around the problem in the mean time by using rc 53.

[tm1000]

For webpack 4 you do something like:

const settings = {
	webpack(config, options) {
		if (config.node.fs) {
			config.node.fs = false;
		}

		return config;
	},
};

module.exports = settings;
