Error ts1343: the ‘import.meta’ meta-property is only allowed when the ‘–module’ option is ‘es2020’, ‘es2022’, ‘esnext’, ‘system’, ‘node16’, or ‘nodenext’.

Error: TS1343: The ‘import.meta’ meta-property is only allowed when the ‘–module’ option is ‘es2020’, ‘es2022’, ‘esnext’, ‘system’, ‘node16’, or ‘nodenext’.

Description: This error occurs when using the ‘import.meta’ syntax, which allows accessing meta-information about the module, but the ‘–module’ option in TypeScript compiler is not set to one of the supported values.

Solution: To resolve this error, you need to specify the correct ‘–module’ option value in your TypeScript configuration.

1. If you are using TypeScript version 4.4 or above, you can set the ‘–module’ option to ‘es2020’, ‘es2022’, ‘esnext’, ‘system’, ‘node16’, or ‘nodenext’ in your ‘tsconfig.json’ file. For example:

{
  "compilerOptions": {
    "module": "es2020",
    ...
  }
}

2. If you are using an older version of TypeScript that does not support the above options, you can transpile your code to a compatible module format using a bundler, like webpack or Rollup. These bundlers can handle the ‘import.meta’ syntax and produce the appropriate output.

Here is an example of using webpack to compile your TypeScript code:

// webpack.config.js
const path = require('path');

module.exports = {
  mode: 'production',
  entry: './src/index.ts',
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist'),
  },
  module: {
    rules: [
      {
        test: /\.tsx?$/,
        use: 'ts-loader',
        exclude: /node_modules/,
      },
    ],
  },
  resolve: {
    extensions: ['.tsx', '.ts', '.js'],
  },
};

Make sure you have installed webpack and the required loaders (e.g., ‘ts-loader’) as dev dependencies. Then, you can build your project using the following command:

webpack

This will transpile your TypeScript code and produce the output bundle file in the specified output path.
