rollup-plugin-http-resolve

library4.0.1-alpha.0jsnpmunverified

A Rollup plugin that resolves imports via HTTP(S) URLs, enabling bundling of code from CDNs like esm.sh or unpkg. Current version 4.0.1-alpha.0 has irregular release cadence (last release ~2022). Key differentiator: it allows Rollup to fetch and bundle dependencies directly from HTTP sources, with optional caching and fallback to CDN resolution. Requires Node.js 14+. Written in TypeScript with built-in types.

Code

Verified usage

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

httpResolve

✓ import { httpResolve } from 'rollup-plugin-http-resolve'

✗ const httpResolve = require('rollup-plugin-http-resolve')

ESM-only package; CommonJS require will fail. Use dynamic import() if needed.

HttpResolveOptions

✓ import type { HttpResolveOptions } from 'rollup-plugin-http-resolve'

✗ import { HttpResolveOptions } from 'rollup-plugin-http-resolve'

Type-only import; do not use at runtime.

Shows basic usage: resolve a remote HTTP import with optional cache and CDN fallback.

import { httpResolve } from 'rollup-plugin-http-resolve'; import { rollup } from 'rollup'; async function bundle() { const bundle = await rollup({ input: 'https://example.com/module.js', plugins: [ httpResolve({ cache: new Map(), fallback(id) { if (!id.startsWith('.')) { return `https://esm.sh/${id}`; } } }) ] }); const { output } = await bundle.generate({ format: 'es' }); console.log(output[0].code); } bundle();

Debug

Known issues

breakingRequires Rollup >=2.0; compatibility with Rollup 3.x is untested.

fix

Ensure Rollup version is >=2.0 and <4.0.0, or test with Rollup 3.x.

affects: >=4.0.0-alpha

deprecatedVersion 4.0.1-alpha.0 is an alpha release and may have unstable APIs.

fix

Use 3.x stable versions if available, or pin to known working alpha.

affects: 4.0.1-alpha.0

gotchaESM-only package; CommonJS require throws error.

fix

Use dynamic import() or convert project to ESM.

affects: >=4.0.0-alpha

gotchaHTTP imports are not cached by default; may cause repeated network requests.

fix

Provide a cache Map in options to avoid redundant fetches.

affects: >=1.0.0

Errors

Common errors & fixes

Error [ERR_REQUIRE_ESM]: require() of ES Module not supported.

Using CommonJS require() to load an ESM-only package.

fix

Use dynamic import: const { httpResolve } = await import('rollup-plugin-http-resolve');

TypeError: httpResolve is not a function or does not provide a plugin.

Incorrect import (default import instead of named import) or mismatched Rollup version.

fix

Use named import: import { httpResolve } from 'rollup-plugin-http-resolve';
