What it is
Svelte is a compiler for building web applications. You write components in a declarative style, and Svelte converts them ahead of time into efficient JavaScript that updates the page's DOM directly. It is aimed at making web interfaces simpler to write while keeping the output lightweight.
- Build a single-page web application with reusable components
- Create interactive widgets or dashboards for a website
- Explore the Svelte tutorial and docs on svelte.dev to learn component-based web development
Great for
- Developers who want to build interactive websites with less boilerplate
- Teams building web apps who prefer a compiler-based approach
- Learners exploring how modern component frameworks work
Not ideal for
- People who need a no-code tool, since Svelte requires writing code
- Projects that must rely only on long-established tooling, because the README gives little detail on ecosystem maturity for this use
How to get it
- 1
Install with a package manager
You'll need: Node.js
Install the svelte package (per the npm package reference in the README badges)
npm install svelte - 2
Run it
- Install Node.js
- Follow the getting-started guide at https://svelte.dev
- Create a component file and run the project's dev server as described in the docs
- 3
Get the most out of it
- Read the official tutorial at svelte.dev for guided examples
- Check the roadmap at svelte.dev/roadmap to see upcoming work
- Join the Discord chat at svelte.dev/chat to ask questions
Downloads
Strengths
- MIT licensed and open source
- Compiles components to JavaScript that surgically updates the DOM, per the README
- Large community with an active Discord chat and a public roadmap
Trade-offs
- The README is short and defers most detail to the external website and docs
- Some setup details and requirements are not stated in the provided README
- Being a compiler-based approach, understanding the build step takes some learning
