How disable eslint-loader of storybook's webpack?

When using Storybook for frontend development, it employs its internal webpack configuration to process various resources. If the project integrates ESLint for code quality and style enforcement, it typically incorporates it into webpack via the eslint-loader. However, during development, you may occasionally need to temporarily disable ESLint checks to accelerate development and debugging.

To disable the eslint-loader in Storybook's webpack configuration, follow these steps:

1. Access Storybook's custom webpack configuration: In the Storybook configuration directory (typically the .storybook directory), create or modify the main.js file.

2. Modify webpack configuration:

   • Use the webpackFinal property to customize the webpack configuration.
   • Iterate through the rules array to locate the rule containing the eslint-loader.
   • Modify or remove this rule, or set its enforce property to false.

Here is an example configuration demonstrating how to disable the eslint-loader in Storybook's webpack configuration:

javascript
// .storybook/main.js
module.exports = {
  // Other configurations

  webpackFinal: async (config) => {
    // Find and disable eslint-loader
    config.module.rules = config.module.rules.map(rule => {
      if (rule.use && rule.use.some(use => use.loader && use.loader.includes('eslint-loader'))) {
        // You can choose to set enforce: false or directly remove this rule
        rule.enforce = false;
      }
      return rule;
    });

    // Return the modified configuration
    return config;
  },
};

In this example, we iterate through all webpack rules to identify a rule using the eslint-loader. If found, we disable it by setting the enforce property to false. You may also choose to modify it differently or completely remove the rule.

After this configuration, when you run Storybook, it will use the modified webpack configuration, and the eslint-loader will no longer perform code quality checks. This can accelerate development, particularly during debugging and in early development stages. Of course, it is recommended to re-enable ESLint checks before code submission to ensure code quality.

The method to disable the ESLint loader in Storybook primarily involves customizing Storybook's webpack configuration. Storybook allows us to extend or modify the built-in webpack configuration through the .storybook/main.js file. Here is one possible method to disable the ESLint loader:

1. Open the .storybook/main.js file: This is the core configuration file for Storybook.
2. Add or modify the webpackFinal configuration: In this configuration, we can modify the default webpack configuration.
3. Modify the rules array to exclude the ESLint loader: In the webpack configuration, all loaders are defined in the rules array. We need to iterate through this array and remove all entries related to ESLint.

Below is a specific implementation example:

javascript
module.exports = {
  webpackFinal: (config) => {
    // Locate and remove the ESLint loader
    config.module.rules = config.module.rules.filter(
      rule => rule.use && rule.use.some(use => use.loader && use.loader.includes('eslint-loader'))
    );

    return config;
  },
};

In this example:

• We first access the rules array within the webpack configuration object.
• We use the filter method to filter this array. We check the use property of each rule object to see if it contains an object with a loader name including 'eslint-loader'.
• If found, the rule is excluded from the final array, thereby effectively disabling the ESLint loader.

This configuration allows Storybook to skip ESLint checks during the build process, which may be useful for rapid prototyping or debugging in certain situations.
