Error: Can't resolve `http`

[ratasorin]

Hello,

I am trying to use rewiremock alongside storybook to mock the behavior of some functions used by React components. Storybook uses webpack5. When trying to npm run storybook I get two errors:

First error: (http polyfill)

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
        - add a fallback 'resolve.fallback: { "http": require.resolve("stream-http") }'
        - install 'stream-http'
If you don't want to include a polyfill, you can use an empty module like this:
        resolve.fallback: { "http": false }

I will attach my storybook config:

Storybook config:

import type { StorybookConfig } from "@storybook/react-webpack5";
import path from "path";

const config: StorybookConfig = {
  stories: [...],
  addons: [...],

  webpackFinal: async (config) => {
    if (config.resolve) {
      config.plugins?.push(new (require('rewiremock/webpack/plugin'))());

      config.resolve.alias = {
        ...config.resolve.alias,
        "@src": path.resolve(__dirname, "../src"),
        "@mocks": path.resolve(__dirname, "../src/mocks"),

        "@security/Can$": path.resolve(
          __dirname,
          "../src/mocks/_security/Can.tsx"
        ),
        "@services/ticket.service$": path.resolve(
          __dirname,
          "../src/mocks/_services/ticket.service.ts"
        ),

        "@services": path.resolve(__dirname, "../src/_services"),
        "@store-types": path.resolve(__dirname, "../src/store/types"),
        "#types": path.resolve(__dirname, "../src/types"),
        "@scss": path.resolve(__dirname, "../src/scss"),
        "@assets": path.resolve(__dirname, "../src/assets"),
        "@security": path.resolve(__dirname, "../src/_security"),

        "@utils/user$": path.resolve(__dirname, "../src/mocks/utils/user.ts"),
        "@utils": path.resolve(__dirname, "../src/utils"),

        "@shared": path.resolve(__dirname, "../src/shared"),
        "@components": path.resolve(__dirname, "../src/components"),
        "@form-validation": path.resolve(__dirname, "../src/FormValidation"),
      };
    }

    config.optimization = {
      ...config.optimization,
      moduleIds: "named"
    }

    return config;
  },

  framework: {
    name: "@storybook/react-webpack5",
    options: {},
  },
  docs: {},
};
export default config;

I will also attach the second error:

Second error:

Error: Unexpected token 'if'

  - node:vm:116 new Script
    node:vm:116:7

  - index.js:513 HtmlWebpackPlugin.evaluateCompilationResult
    [ui]/[html-webpack-plugin]/index.js:513:22

  - index.js:1105 
    [ui]/[html-webpack-plugin]/index.js:1105:23

  - task_queues:95 process.processTicksAndRejections
    node:internal/process/task_queues:95:5

  - async Promise.all

  - async Promise.all

I should mention I also use CRA for react. I read that I should make some configurations to my .babelrc, but is there a way to do that only for the Storybook config?

What is my configuration missing, that's causing the issue?

I would appreciate a lot if someone could create a complete demo repository for react + storybook + rewiremock

Webpack is a little 🤒 right now, but there is a solution found at https://github.com/theKashey/rewiremock/issues/134

Speaking of react + storybook - I would recommend something I am using myself - https://github.com/albertogasparin/react-magnetic-di/tree/master

Thank you! This looks very promising! I will give it a try!
