JSON

Rspack has built-in support for JSON, and you can import JSON files directly.

Default import

json

{
  "foo": "bar"
}

import json from './example.json';
console.log(json.foo); // "bar"

In non-.mjs non-strict ESM files, you can directly import properties from JSON.

json

{
  "foo": "bar"
}

import { foo } from './example.json';
console.log(foo); // "bar"

Rspack supports import attributes, and you can use import attributes to import JSON:

import json from './example.json' with { type: 'json' };
import('./example.json', { with: { type: 'json' } });
