jest-transform-stealthy-require

Transforms stealthy-require calls into jest.isolateModules()

Motivation

The purpose of this module is to address Jest + stealthy-require compatibility issue which causes issues like Unable to expose method "then" on modules that depend on stealthy-require.

Getting started

Installation

1npm install --save-dev jest-transform-stealthy-require

Jest configuration

For request-promise/request-promise-native issue

Jest

jest.config.js

1const { requestPromise } = require('jest-transform-stealthy-require/dist/presets');
2
3module.exports = {
4  // ...
5  transform: {
6    ...requestPromise.transform
7  },
8  transformIgnorePatterns: [requestPromise.transformIgnorePattern]
9};

Jest + babel-jest

jest.config.js

1const { requestPromise } = require('jest-transform-stealthy-require/dist/presets');
2
3module.exports = {
4  // ...
5  transform: {
6    ...requestPromise.transform,
7    "^.+\\.[t|j]sx?$": "babel-jest"
8  },
9  transformIgnorePatterns: [requestPromise.transformIgnorePattern]
10}

Jest + ts-jest

jest.config.js

1const { requestPromise } = require('jest-transform-stealthy-require/dist/presets');
2const { defaults: tsjPreset } = require('ts-jest/presets');
3// [OR] const { jsWithTs: tsjPreset } = require('ts-jest/presets');
4// [OR] const { jsWithBabel: tsjPreset } = require('ts-jest/presets');
5
6module.exports = {
7  // ...
8  transform: {
9    ...requestPromise.transform,
10    ...tsjPreset.transform
11  },
12  transformIgnorePatterns: [requestPromise.transformIgnorePattern]
13}

For other cases

The transformer can be used to replace stealthy-require calls in arbitrary modules. Simply specify the file pattern to for the modules that you would like to transform in your Jest config:

jest.config.js

1
2module.exports = {
3  // ...
4  transform: {
5    'my_pattern_to_module_to_transform': 'jest-transform-stealthy-require'
6  }
7};
