rollup-plugin-svelte-hot

library1.0.0-8jsnpmunverified

Rollup plugin for compiling Svelte components with built-in Hot Module Replacement (HMR) support. Version 1.0.0-8, pre-release, requires Rollup >= 2.0.0 and Svelte >= 3.5.0. Supports both Rollup and Nollup bundlers. Unlike standard rollup-plugin-svelte, this plugin adds HMR capabilities, making it suitable for development workflows. Maintained by rixo, with TypeScript definitions included. Release cadence is irregular, with multiple alpha/beta tags.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import svelte from 'rollup-plugin-svelte-hot'

✗ const svelte = require('rollup-plugin-svelte-hot')

ESM exports default function. CJS require() works in Node.js, but ESM is preferred for bundlers.

svelte

✓ import { svelte } from 'rollup-plugin-svelte-hot'

✗ import { rollupPluginSvelte } from 'rollup-plugin-svelte-hot'

Named export 'svelte' is also available, same as default.

hotOptions

✓ import { hotOptions } from 'rollup-plugin-svelte-hot'

Optional helper for setting HMR options, TypeScript typed.

Minimal Rollup config with svelte-hot, HMR, dev server, and production minification.

import svelte from 'rollup-plugin-svelte-hot'; import resolve from '@rollup/plugin-node-resolve'; import commonjs from '@rollup/plugin-commonjs'; import livereload from 'rollup-plugin-livereload'; import { terser } from 'rollup-plugin-terser'; const production = !process.env.ROLLUP_WATCH; export default { input: 'src/main.js', output: { sourcemap: true, format: 'iife', name: 'app', file: 'public/build/bundle.js' }, plugins: [ svelte({ dev: !production, css: css => css.write('public/build/bundle.css'), hot: production ? false : {} }), resolve({ browser: true, dedupe: ['svelte'] }), commonjs(), !production && livereload('public'), production && terser() ] };

Debug

Known issues

breakingRequires rollup >= 2.0.0 and svelte >= 3.5.0

fix

Upgrade rollup and svelte to meet minimum versions.

affects: <0.10

deprecatedNollup dependency is optional since v0.14.1; may be removed in future.

fix

Explicitly install nollup if using Nollup.

affects: >=0.14.1

gotchaEnsure 'svelte' is deduplicated in @rollup/plugin-node-resolve to avoid multiple Svelte instances.

fix

Add 'dedupe: ['svelte']' to resolve options.

affects: all

gotchaHMR only works in 'dev' mode; set 'hot' to false or omit in production.

fix

Use 'const production = !process.env.ROLLUP_WATCH' and conditionally enable hot.

affects: all

gotchaCSS output with HMR: writes a blank CSS file; suppresses warning with Nollup.

fix

Upgrade to 0.11.2+ or ignore blank CSS file.

affects: <=0.11.2
