rollup-plugin-variables

library0.1.1jsnpmunverified

A Rollup plugin that replaces custom markers (e.g., [[VARIABLE]]) in source files with values from a separate variables file (JS, JSON, or TXT). Stable version 0.1.1. Low activity; last release in 2019. Key differentiator: allows externalizing environment-specific values without a full-fledged env replacement plugin. Limited to rollup.

Verified usage

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

default

✓ import variables from 'rollup-plugin-variables'

✗ const variables = require('rollup-plugin-variables')

ESM default import is only supported; CommonJS require may work if using a bundler

variables

✓ import variables from 'rollup-plugin-variables'

✗ import { variables } from 'rollup-plugin-variables'

Named export does not exist; use default import

None (type import)

✓ import type { RollupOptions } from 'rollup'; import variables from 'rollup-plugin-variables';

No dedicated type exports; types inferred from Rollup

Configures Rollup to replace [[variables]] with values from env.js during build.

// rollup.config.js import variables from 'rollup-plugin-variables'; export default { input: 'src/index.js', output: { file: 'dist/bundle.js', format: 'iife' }, plugins: [ variables({ fileName: 'env.js', format: 'js', marker: '[[]]' }) ] };

Debug

Known issues

gotchaDefault marker is [[]]; double brackets required.

fix

Ensure source files use [[VARIABLE_NAME]] syntax, or configure marker option.

affects: >=0.1.0

gotchaVariables file must export an object (module.exports = ...) when format is 'js'.

fix

Use module.exports = { KEY: 'value' } in .js file; for .json use JSON object directly.

affects: >=0.1.0

deprecatedPlugin is in maintenance mode; no updates expected.

fix

Consider migrating to @rollup/plugin-replace or similar.

affects: >=0.1.0

gotchaNested markers (e.g., [[[VAR]]]) not supported; will cause undefined replacement.

fix

Use flat variable names without nested brackets.

affects: >=0.1.0

Errors

Common errors & fixes

Error: Cannot find module './env.js'

Variables file path is resolved relative to rollup.config.js; file missing or incorrect.

fix

Ensure env.js exists in the same directory as rollup.config.js or provide absolute path via fileName option.

TypeError: variables is not a function

Using named import { variables } instead of default import.

fix

Use default import: import variables from 'rollup-plugin-variables'.

The marker format 'invalid' is not supported.

Marker option string or function must return a valid format like '[[]]' or '{{}}'.

fix

Use supported marker format: '[[]]', '{{}}', or another string with matching brackets.
