How to ignore typescript errors with webpack?

@dana 

To ignore TypeScript errors with webpack, you can use the ignoreErrors option in the ts-loader configuration. Here are the steps to do it:

1. Install the necessary packages:

1

npm install --save-dev typescript ts-loader

1. Create a tsconfig.json file in the root directory of your project. This file specifies the TypeScript compiler options. You can modify it based on your requirements.
2. Create or update your webpack configuration file (webpack.config.js) to include the ts-loader configuration. Here's an example:

module.exports = {
  // Other webpack configuration options...
  module: {
    rules: [
      {
        test: /.tsx?$/,
        exclude: /node_modules/,
        use: [
          {
            loader: 'ts-loader',
            options: {
              transpileOnly: true, // Enables transpilation without type checking
              ignoreDiagnostics: [ /* Array of error codes to ignore */ ],
            },
          },
        ],
      },
    ],
  },
  resolve: {
    extensions: ['.tsx', '.ts', '.js'],
  },
  // Other webpack configuration options...
};

1. In the options object of ts-loader, set transpileOnly to true. This option enables transpilation without type checking.
2. In the options object of ts-loader, specify the ignoreDiagnostics array to list the error codes that you want to ignore. You can find the list of TypeScript compiler error codes in the TypeScript documentation. For example, to ignore error code 6133 and 6139, you can set ignoreDiagnostics: [6133, 6139].
3. Run webpack to build your project, and it will ignore the specified TypeScript errors.

Note: Ignoring TypeScript errors should be used with caution, as it can lead to potential bugs and issues in your code. It's recommended to fix the errors rather than ignoring them if possible.
