Walkthrough

Replaced all uses of window.* accessors with globalThis.* in the service worker registration file to reference location, origin, URL resolution, event binding, and reload behavior.

Changes

Cohort / File(s) Change Summary
Service worker global accessors
templates/react-ts/template/src/serviceWorker.ts
Replaced window.location.hostname/href/origin, window.addEventListener('load', ...), and window.location.reload() with globalThis.location.hostname/href/origin, globalThis.addEventListener('load', ...), and globalThis.location.reload() respectively. Verify URL/origin checks and event binding usages.

1-42: LGTM, but consider customizing the styles.

The CSS styles in the file look good. They are standard styles that are commonly used in React applications and do not contain any obvious issues.

However, the styles seem to be based on a template or boilerplate. Consider customizing the styles to match the specific design and requirements of your application.

apps/react-vite/tsconfig.node.json (1)

1-10: LGTM!

The tsconfig.node.json file is correctly configured for a Node.js environment used by Vite.

components/react/lib/index.ts (1)

9-9: LGTM!

The dynamic import of the tsParticles module is a good optimization that allows for the module to be loaded only when the initParticlesEngine function is invoked, potentially improving performance by reducing the initial load time of the module.

apps/react-vite/.eslintrc.cjs (1)

1-18: LGTM!

The .eslintrc.cjs file is correctly configured for a React application using Vite.

  • It extends recommended configurations and enables additional plugins for TypeScript and React.
  • The react-refresh/only-export-components rule is correctly configured to allow constant exports.
  • The ignorePatterns property is correctly configured to ignore the dist directory and the .eslintrc.cjs file itself.
apps/nextjs/package.json (1)

13-19: LGTM!

The changes to the @tsparticles dependencies look good. The removal of @tsparticles/preset-big-circles, the addition of @tsparticles/configs and tsparticles, and the version upgrade of @tsparticles/engine are consistent with the PR summary.

apps/react-vite/tsconfig.json (1)

1-25: LGTM!

The tsconfig.json file looks good. The compiler options are appropriately configured for a modern React application using Vite. The strict type checking options will help catch potential issues. The include and references options are also set correctly.

components/react/lib/Particles.tsx (1)

11-21: LGTM!

The changes to the useEffect hook introduce a more efficient loading strategy for the tsParticles module. By dynamically importing the module within an async function, the initial rendering of the component is not blocked. The overall functionality remains intact, and the particlesLoaded callback is still invoked with the loaded container.

The code changes are approved.

apps/react-vite/package.json (1)

1-31: LGTM!

The package.json file is a standard configuration file for a React application using Vite. The dependencies and devDependencies are necessary for the application to function properly.

The code changes are approved.

apps/react-vite/README.md (1)

1-30: LGTM!

The README.md file provides helpful information about the React + TypeScript + Vite template and instructions for expanding the ESLint configuration.

The code changes are approved.

apps/react-vite/src/App.tsx (1)

1-72: LGTM!

The code changes in this new file are approved. The React component is well-structured and follows best practices. It correctly initializes the particles engine, loads the full package, and renders the Particles component with appropriate options. The component also properly manages the particles initialization state using the useState and useEffect hooks.

apps/nextjs/pages/index.js (4)

4-4: LGTM!

The import statement for configs from @tsparticles/configs is correct and follows the proper syntax.


5-5: LGTM!

The import statement for loadFull from tsparticles is correct and follows the proper syntax.


13-13: LGTM!

The change from loadBigCirclesPreset to loadFull is appropriate as it suggests a shift from a specific preset to a more comprehensive loading function. The await keyword is used correctly to wait for the loadFull function to complete before proceeding.


92-92: LGTM!

The change from options={options} to options={configs.basic} is a good improvement as it suggests that the particle configuration is now being sourced from a centralized configuration file. This change enhances maintainability and flexibility by allowing for easier updates to particle settings through the configuration file.

This PR updates the repository to version 3.0.1, focusing on dependency upgrades, performance improvements through dynamic imports, and adding a new Vite-based React application template. The main changes include updating @tsparticles packages from 3.0.2 to 3.2.2, implementing dynamic loading for the tsParticles engine in React components to improve code splitting, and replacing window references with globalThis in the service worker for better cross-environment compatibility.

Key Changes:

  • Updated @tsparticles dependencies from 3.0.2/3.0.0 to 3.2.2 across all packages
  • Implemented dynamic imports in React components to enable lazy loading of the tsParticles engine
  • Replaced window with globalThis in serviceWorker.ts for improved cross-environment compatibility
  • Added new react-vite application with TypeScript and Vite configuration
  • Removed Slack communication channel from README

🧹 Nitpick comments (1)
templates/react-ts/template/src/serviceWorker.ts (1)

42-42: Consider semantic clarity: window vs globalThis for browser-specific APIs.

While globalThis.addEventListener('load', ...) is functionally correct in browser contexts, the load event is specific to the window object. Service worker registration inherently requires a browser window context, so using window.addEventListener would be more semantically explicit about the execution environment.

This is not a functional issue, but it may affect code readability and intent clarity.

31-40: Changes look correct for URL construction and origin validation.

The migration to globalThis.location.href (line 33) and globalThis.location.origin (line 35) is functionally correct. These changes maintain the expected behavior for validating that the service worker and page are served from the same origin.


124-124: Migration to globalThis.location.reload() is consistent.

The change from window.location.reload() to globalThis.location.reload() is functionally correct and consistent with the other location API updates throughout the file.

🌐 Web query:

globalThis browser compatibility ES2020 support

💡 Result:

globalThis (part of the ES2020/ECMAScript proposal) is widely supported in modern browsers: Chrome 71+, Firefox 65+, Safari 12.1+, Edge 79+ and Node.js 12+; Internet Explorer does not support it. Use a polyfill (or core-js/es-shims) for older browsers. [1][2][3]


Remove globalThis references; revert to window for ES5 compatibility.

The TypeScript configuration explicitly targets es5 (compilerOptions.target), but globalThis is an ES2020 feature with no support in Internet Explorer or older browser versions. Using globalThis breaks compatibility with the declared target. Additionally, service worker registration code runs exclusively in the browser window context, where window is universally available and more appropriate than globalThis. Revert the changes on lines 14, 16, 18, 33, 35, 42, and 124 to use window instead.
