 - Direct support for meta framework files based on TS Plugin without a parser. (e.g., Vue, MDX)

-- Supports HTTP URL import, no need to add dependencies in package.json.

-### Import Rules from HTTP URL
-
-You can directly import rules from other repositories using HTTP URLs. This allows you to easily share and reuse rules across different projects.
-
-Here's an example of how to import a rule from a HTTP URL:
-
-```diff
-import { defineConfig } from '@tsslint/config';
-
-export default defineConfig({
-	rules: {
-		'no-console': (await import('./rules/noConsoleRule.ts')).create(),
-+ 		'no-alert': (await import('https://gist.githubusercontent.com/johnsoncodehk/55a4c45a5a35fc30b83de20507fb2bdc/raw/5f9c9a67ace76c0a77995fd71c3fb4fb504a40c8/TSSLint_noAlertRule.ts')).create(),
-	},
-});
-```
-
-In this example, the `no-alert` rule is imported from a file hosted on GitHub. After saving the config file, you will notice that `alert()` calls are now reporting errors in the editor.

 ### Modify the Error
 
 While you cannot directly configure the severity of a rule, you can modify the reported errors through the `resolveDiagnostics()` API in the config file. This allows you to customize the severity of specific rules and even add additional errors.
