rollup-to-nej

library1.3.0jsnpmunverified

A build tool that transforms Vue single-file components (.vue) and ES module code into NEJ-style AMD modules with NEJ.define() wrappers. Current version 1.3.0. Provides a command-line interface (roll, rollup) and programmatic API (doRollup). Supports alias mapping to avoid bundling common modules, comment removal, and external Babel helpers. It is a niche tool for projects migrating from Vue/ESM to the NEJ module system, with no active development observed since 2020.

Code

Verified usage

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

default export of rollup-to-nej

✓ const doRollup = require('rollup-to-nej');

✗ import doRollup from 'rollup-to-nej';

Package does not provide ESM exports; use CommonJS require even in Node.js ESM modules.

doRollup.build

✓ doRollup.build('vue', { input: 'raw', output: 'src' });

✗ doRollup('vue', { input: 'raw', output: 'src' });

The main export is not a function; access the build method on the exported object.

CLI commands

✓ roll build vue -i raw -o src

✗ rollup-to-nej build vue

CLI is invoked via the 'roll' binary, not the package name. Use npx roll ... or install globally.

Programmatic build using the API: bundles .vue and .js files from 'raw' to 'src' with NEJ.define wrapping, aliases, and option to remove comments.

const doRollup = require('rollup-to-nej'); doRollup.build('vue', { input: 'raw', output: 'src', alias: { '@nej': './src', 'vueSrc': '../../' }, removeComments: true, externalHelpers: false });

Debug

Known issues

breakingDeprecated and unmaintained: no updates since 2020. May not work with modern Rollup or Vue versions (>2.x).

fix

Consider migrating to Vite or webpack with NEJ plugins if needed.

affects: >=1.0

gotchaThe CLI binary is named 'roll' (not 'rollup-to-nej' or 'rollup'). Installing globally or using npx requires exact command.

fix

Use 'npx roll build vue ...' or install globally with 'npm i -g rollup-to-nej'.

affects: >=1.0

gotchaAlias syntax requires careful quoting: -s @nej=./src (no spaces around =). Using @ inside aliases (e.g., @**) is not recommended.

fix

Always quote or escape values that contain special shell characters, e.g., -s "@nej=./src".

affects: >=1.0

deprecatedThe generated code includes a 'normalizeComponent' function from vue-component-compiler, which may not be compatible with Vue 3 or NEJ updates.

fix

Manually review and adjust output for target environment.

affects: >=1.0

Errors

Common errors & fixes

Error: Cannot find module 'rollup-to-nej'

Package not installed or incorrectly required (e.g., using import instead of require).

fix

Install via 'npm install rollup-to-nej' and use 'const doRollup = require('rollup-to-nej');'

roll: command not found

CLI binary 'roll' not in PATH; package not installed globally or not used via npx.

fix

Use 'npx roll ...' or install globally: 'npm i -g rollup-to-nej'.

SyntaxError: Unexpected token '<'

Input file is a .vue template but the tool expects JavaScript; missing proper .vue file extension or configuration.

fix

Ensure input files have .vue extension and the 'vue' preset is used: 'roll build vue -i ...'
