library2.0.1jsnpmunverified

interpolate-loader is a Webpack loader for interpolating require results within files, such as JSON manifest files. The current stable version is 2.0.1, which requires Webpack >=3.0.0. It replaces template placeholders like {{...}} with resolved Webpack module outputs, enabling dynamic injection of metadata, file references, or resource URLs. Key differentiators include customizable prefix/suffix delimiters and compatibility with companion loaders like prop-loader and extricate-loader.

interpolate-loader

✓ import interpolateLoader from 'interpolate-loader';

✗ const interpolateLoader = require('interpolate-loader');

ESM import works in Webpack config; CommonJS require is also acceptable in Node.js.

Shows how to use interpolate-loader in a Webpack configuration to process a JSON manifest file and interpolate placeholders.

// webpack.config.js module.exports = { entry: 'extricate-loader!interpolate-loader!manifest.json', output: { filename: 'manifest.json' }, module: { rules: [ { test: /\.html$/, use: [ { loader: 'file-loader', options: { name: '[name].[ext]' } }, 'extricate-loader', 'html-loader' ] } ] }, plugins: [ new (require('inert-entry-webpack-plugin'))() ] };

Debug

Known issues

breakingv2.0.0 requires Webpack >=3.0.0, breaking compatibility with Webpack <3.

fix

Upgrade Webpack to version 3.0.0 or later.

affects: >=2.0.0

breakingv1.0.0 drops support for Node <4 and requires Webpack >=2.0.0.

fix

Update Node.js to version 4+ and Webpack to 2+.

affects: >=1.0.0 <2.0.0

gotchaThe loader uses default prefix {{ and suffix }}, but custom delimiters must include both prefix and suffix in query string.

fix

Use query format: interpolate-loader?prefix=(*&suffix=*).

affects: >=1.0.0

Errors

Common errors & fixes

Module not found: Error: Can't resolve 'interpolate-loader'

interpolate-loader is not installed as a dev dependency.

fix

Run npm install --save-dev interpolate-loader

Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.

Using Webpack 4+ with modern module rules syntax, but loader is configured incorrectly.

fix

Ensure rule uses 'use' array with loader strings or objects, e.g., { test: /\.json$/, use: 'interpolate-loader' }
