rollup-plugin-auto-transform

library1.0.2jsnpmunverified

An automatic transform plugin for Rollup that mimics Browserify's transform resolution by reading the `browserify.transform` key in package.json. As of version 1.0.2 (stable, single release), it simplifies applying Browserify transforms (e.g., brfs, envify) to Rollup bundles without manual configuration. Unlike manual plugin arrays, it reads transforms from package.json automatically, reducing setup duplication. No active development since 2017; considered feature-complete for its narrow use case. Alternative: use Rollup plugins directly or @rollup/plugin-commonjs for broader compatibility.

Verified usage

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

default

✓ import autoTransform from 'rollup-plugin-auto-transform'

✗ const { autoTransform } = require('rollup-plugin-auto-transform')

The package exports a single function as default. Named export is incorrect.

autoTransform (named import attempt)

✓ import autoTransform from 'rollup-plugin-auto-transform'

✗ import { autoTransform } from 'rollup-plugin-auto-transform'

Only default export exists; named import will be undefined.

CommonJS require

✓ const autoTransform = require('rollup-plugin-auto-transform')

✗ const { default: autoTransform } = require('rollup-plugin-auto-transform')

In CJS, require returns the default export directly.

TypeScript import

✓ import autoTransform from 'rollup-plugin-auto-transform'

No type definitions are bundled; use @types or inline type if needed.

Shows how to use the plugin to automatically apply Browserify transforms defined in package.json to a Rollup bundle.

import autoTransform from 'rollup-plugin-auto-transform'; import { rollup } from 'rollup'; const bundle = await rollup({ input: 'src/index.js', plugins: [ autoTransform() ] }); const { output } = await bundle.generate({ format: 'esm' }); console.log(output[0].code);

Debug

Known issues

deprecatedPackage is no longer actively maintained; last release in 2017.

fix

Consider using direct Rollup plugins (e.g., @rollup/plugin-commonjs, rollup-plugin-babel) or @rollup/plugin-node-resolve for better compatibility.

affects: >=1.0.0

gotchaTransforms must be listed under 'browserify.transform' in package.json; other keys are ignored.

fix

Ensure your package.json has a 'browserify.transform' array. Example: { "browserify": { "transform": ["brfs"] } }

affects: >=1.0.0

gotchaTransforms are applied globally, not per-file; may cause unexpected behavior with non-Browserify transforms.

fix

Review each transform's compatibility with Rollup. Some Browserify transforms rely on Node.js streams or other Browserify internals.

affects: >=1.0.0

Errors

Common errors & fixes

Cannot find module 'rollup-plugin-auto-transform'

Package not installed or import path incorrect.

fix

Run `npm install rollup-plugin-auto-transform` and ensure import is correct: `import autoTransform from 'rollup-plugin-auto-transform'`

TypeError: autoTransform is not a function

Using named import instead of default import.

fix

Use default import: `import autoTransform from 'rollup-plugin-auto-transform'` instead of `import { autoTransform } from...`

Error: Could not resolve 'your-transform' from .../

Transform package not installed but listed in package.json.

fix

Install the transform package (e.g., `npm install brfs`) or remove it from 'browserify.transform'.
