SaelixCode 753b0c3539 fix(logs): use monotonic _id key to prevent O(n) DOM mutations on scroll
key={idx} with a shifting .slice(-300) window meant every new log arrival
caused React to update all 300 existing DOM nodes (index 1 became 0, 2
became 1, etc.), even though only one entry actually changed.

The proposed content-hash fix (timestamp + containerName + message.substring)
carries a real collision risk: chatty containers emitting identical lines at
the same millisecond produce duplicate keys, triggering undefined React
reconciliation behaviour.

Fix: add a _id: number field to LogEntry, stamped client-side with a
monotonic counter (logIdRef) at the point of ingestion — once in the SSE
onmessage handler and once in the polling setLogs path. React now tracks
data identity rather than position, so the slice window can shift without
touching the 299 unchanged DOM nodes.

React + TypeScript + Vite

This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

React Compiler

The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.

Expanding the ESLint configuration

If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:

export default defineConfig([
  globalIgnores(['dist']),
  {
    files: ['**/*.{ts,tsx}'],
    extends: [
      // Other configs...

      // Remove tseslint.configs.recommended and replace with this
      tseslint.configs.recommendedTypeChecked,
      // Alternatively, use this for stricter rules
      tseslint.configs.strictTypeChecked,
      // Optionally, add this for stylistic rules
      tseslint.configs.stylisticTypeChecked,

      // Other configs...
    ],
    languageOptions: {
      parserOptions: {
        project: ['./tsconfig.node.json', './tsconfig.app.json'],
        tsconfigRootDir: import.meta.dirname,
      },
      // other options...
    },
  },
])

You can also install eslint-plugin-react-x and eslint-plugin-react-dom for React-specific lint rules:

// eslint.config.js
import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'

export default defineConfig([
  globalIgnores(['dist']),
  {
    files: ['**/*.{ts,tsx}'],
    extends: [
      // Other configs...
      // Enable lint rules for React
      reactX.configs['recommended-typescript'],
      // Enable lint rules for React DOM
      reactDom.configs.recommended,
    ],
    languageOptions: {
      parserOptions: {
        project: ['./tsconfig.node.json', './tsconfig.app.json'],
        tsconfigRootDir: import.meta.dirname,
      },
      // other options...
    },
  },
])
