FAQPage Schema

How do I set up a modern JavaScript project with Vite and the latest ES2024 features?▼

Set up a modern JavaScript project by creating a new Vite application using the vanilla template, then leverage ES2024 features like Set operations and Promise.withResolvers. This provides an up-to-date tooling environment for Node.js, Bun, or Deno.

Does this support backend development with Fastify, Express, and Hono on Node.js 22 LTS?▼

Yes, it supports backend development across Node.js 22 LTS, Bun 1.x, and Deno 2.x. You can build high-performance APIs using frameworks like Fastify, Express, and Hono within these contemporary JavaScript runtime environments.

What's the best way to configure ESLint 9 and Biome for linting a Node.js API?▼

The best way to configure linting is by utilizing ESLint 9 and Biome directly within your Node.js project workflow. These tools ensure code quality and consistency across your JavaScript API and web application codebase.

How do I run tests using Vitest or Jest in a Bun or Deno runtime environment?▼

Run tests by integrating Vitest or Jest into your Bun 1.x or Deno 2.x project configuration. This Skill facilitates contemporary testing workflows, ensuring your JavaScript applications are validated across multiple supported runtimes.

Can I use modern JavaScript bundlers like esbuild and Rollup with Vite?▼

Yes, you can use Vite alongside modern bundlers like esbuild and Rollup. This Skill supports contemporary development workflows, allowing efficient building and bundling of JavaScript APIs and web applications using these tools.

What are the limitations when developing JavaScript applications for multiple runtimes like Node.js, Bun, and Deno?▼

Developing across Node.js 22 LTS, Bun 1.x, and Deno 2.x requires managing runtime-specific API differences despite shared ES2024+ support. Ensure your chosen backend framework, like Express or Hono, is fully compatible with your specific target runtime.
