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.
- 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",
...
}
}
- 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.
