bug: logLevel enum is not exported

[5im0n]

Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

v8.x

Current Behavior

The release of Ionic 8.5.0 introduced the logLevel option in IonicConfig.

However, the LogLevel enum is not exported by the @ionic/core module.
As a result, we are unable to use LogLevel.OFF (or any other value from LogLevel) when defining the logLevel property in IonicConfig.

We can't configure it

import { IonicConfig, LogLevel } from '@ionic/core'; // Error LogLevel  is not exported

export const ionicConfig: IonicConfig = {
  logLevel: LogLevel.OFF,
  mode: 'md',
  spinner: 'lines',
  swipeBackEnabled: false,
};

Expected Behavior

The LogLevel enum should be properly exported by @ionic/core, allowing developers to set the logLevel in IonicConfig without any import issues.

import { IonicConfig, LogLevel } from '@ionic/core';

const config: IonicConfig = {
  logLevel: LogLevel.OFF, // ✅ This should work without any import issues
  mode: 'md',
  spinner: 'lines',
  swipeBackEnabled: false,
};

Steps to Reproduce

1. Install or upgrade to @ionic/core version 8.5.0.
2. Import LogLevel from @ionic/core in a TypeScript file.
3. Define logLevel: LogLevel.OFF inside IonicConfig.
4. Observe that TypeScript raises an error due to LogLevel not being exported.

Thank you @brandyscarney for the resolution! 🙏

However, there's a small issue with the way LogLevel is exported in @ionic/core. It's currently declared as a const enum, which causes problems when using the isolatedModules option in tsconfig.json.

According to the TypeScript documentation, const enums are not supported with isolatedModules enabled:
https://www.typescriptlang.org/docs/handbook/enums.html#const-enum-pitfalls

For example, the following code will fail to compile:

import { IonicConfig, LogLevel } from '@ionic/core';

export const ionicConfig: IonicConfig = {
  logLevel: LogLevel.ERROR, // ❌ Error: Cannot access ambient const enums when 'isolatedModules' is enabled
};

Would it be possible to switch LogLevel to a regular enum instead of a const enum in the package?

Thanks again
