jest-raw-loader

library1.0.1jsnpmunverified

Jest transformer that imports files as raw strings, mimicking webpack-contrib/raw-loader for testing. Current stable version 1.0.1 (last release Jul 22, 2018; long-term maintenance unclear). It reads file content and returns it as a module exporting the string. Simple configuration via Jest's transform option. Unlike other loaders, it directly replaces file imports with their raw content, useful for testing components that import .graphql, .md, or .txt files. No updates since 2018, so may not support newer Jest versions.

Verified usage

jest-raw-loader

✓ // package used as Jest transformer in config, not directly imported

✗ const rawLoader = require('jest-raw-loader')

This is a Jest transformer, not a module to import. Configure via jest.transform in package.json or jest.config.js.

jest.transform

✓ "jest": { "transform": { "\\.graphql$": "jest-raw-loader" } }

✗ "jest": { "transform": { "\\.graphql$": "jest-raw-loader/index.js" } }

Specify the module name directly, not path to index.js.

Raw file import

✓ import content from './example.graphql'; // content is a string

✗ const content = require('./example.graphql'); // works but CJS

After configuring, imports of matched files return the raw string. Use ESM or CJS as needed.

Configure Jest to import .graphql and .md files as raw strings, then verify in a test.

// package.json { "jest": { "transform": { "\\.graphql$": "jest-raw-loader", "\\.md$": "jest-raw-loader" } }, "devDependencies": { "jest-raw-loader": "^1.0.1" } } // example.test.js import graphqlContent from './schema.graphql'; test('returns raw string', () => { expect(typeof graphqlContent).toBe('string'); expect(graphqlContent).toContain('type Query'); });

Known issues

breakingjest-raw-loader may not work with Jest 27+ due to changes in transformer API (sync vs async).

fix

Use a more maintained transformer like jest-transform-raw, or configure Jest custom transformer manually.

affects: <=1.0.1

deprecatedPackage has not been updated since 2018; consider it in maintenance mode.

fix

Evaluate alternatives if you need active maintenance or newer Jest support.

affects: >=0.0.0

gotchaTransform configuration uses regex patterns, not globs. Backslashes in JSON must be double-escaped.

fix

Use "\\.graphql$" (escaped backslash and dot) instead of ".graphql".

affects: >=0.0.0

Errors

Common errors & fixes

Cannot find module 'jest-raw-loader'

Package not installed or not in devDependencies.

fix

Run 'npm install --save-dev jest-raw-loader'

TypeError: Transformer is not a function

Jest version incompatible (Jest 27+ expects async transformer).

fix

Upgrade to a compatible transformer or downgrade Jest to <=26.

Invalid regular expression: /\\.graphql/: \ at end of pattern

Mis-escaped regex in JSON configuration.

fix

Use double backslashes: "\\.graphql$"
