react-resizable-panels
React components for resizable panel groups/layouts
react-resizable-panels provides accessible, flexible split-view layouts for React without wrestling low-level pointer math yourself. It models layouts as “groups” of panels separated by resize handles, supporting horizontal or vertical orientation and mixed min/max constraints that prevent panels from collapsing unexpectedly. The library focuses on smooth interactions: dragging, double-clicking to reset, and keyboard resizing for users who rely on accessibility features. It also supports snapping, collapsed states, and layout persistence so your app can remember user preferences between sessions. Because the API is component-based, you can nest groups, render custom panel contents, and style handles to match your design system. Under the hood, it keeps measurement logic reliable across reflows and React 18 rendering patterns, making it suitable for IDE-like UIs, data dashboards, and inspector panes. -

Night Owl
VS Code dark theme for contrast for nighttime coding
Night Owl is a theme for Visual Studio Code designed by Sarah Drasner to provide a comfortable, high-contrast coding environment especially optimized for late-night development sessions and users who prefer dark themes. It also includes a “Light Owl” variant for daytime or brighter environments, giving users a consistent visual identity whether coding at night or day. The color palette is carefully chosen, with accessibility in mind (including better visibility for color-blind users) and optimal contrast for readability and long working sessions. The theme supports syntax highlighting across many languages and file types in VS Code, and has become a popular choice in the developer community. The repository is maintained as an open-source project, allowing users to inspect color choices, customize the theme further, or contribute new variants. Night Owl’s popularity reflects how much the developer experience can benefit from thoughtful UI design—it’s more than aesthetics. -

Styled Components
Visual primitives for the component age
Visual primitives for the component age. Use the best bits of ES6 and CSS to style your apps without stress. Utilising tagged template literals (a recent addition to JavaScript) and the power of CSS, styled-components allows you to write actual CSS code to style your components. It also removes the mapping between components and styles, using components as a low-level styling construct could not be easier! Alternatively, you may use style objects. This allows for easy porting of CSS from inline styles, while still supporting the more advanced styled-components capabilities like component selectors and media queries. styled-components is compatible with both React (for web) and React Native, meaning it's the perfect choice even for truly universal apps! If you're using tooling that has babel-plugin-macros set up, you can switch to the styled-components/macro import path instead to gain the effects of the babel plugin without further setup. -

Synthwave ’84 (VSCode Theme)
Synthwave inspired colour theme for VS Code
synthwave-vscode is a visual theme extension for Visual Studio Code that gives the editor a retro, neon-drenched look reminiscent of 1980s synthwave aesthetics. It applies a dark base palette with bold accent colors, glowing highlights, and sharp contrasts to bring an edgy, stylized atmosphere to coding sessions. Syntax highlighting is tuned to balance readability with dramatic flair, ensuring code elements don’t get lost while preserving the cool visual vibe. The theme also includes optional “neon glow” effects on UI elements, cursor styles, and sidebars for users who want a more immersive style. Many users choose it to inject personality into their development environment—especially in late-night coding sessions. Because it’s just a theme, it can be layered with other UI tweaks or paired with complementary icon packs and UI themes in VS Code. -
