jest-config

Opinionated jest config for my projects.

Usage

• Install config file:

npm install --D @levibostian/jest-config

If you need to set multiple preset options in Jest (example if you are using ts-jest), you need to install those dependencies yourself:

npm install --D ts-jest

• In your jest.config.js file, setup Jest to use the present. The code sample below allows you to use 2 preset options for Jest. Jest only allows 1 string for preset in the jest config file so we do a manual merge instead.

/* eslint-disable */

const tsPreset = require("ts-jest/jest-preset")
const customPreset = require("@levibostian/jest-config/jest-preset")

// If you want to override any settings, feel free! This is just an object like any other in a jest config file. 
module.exports = {
  ...tsPreset,
  ...customPreset  
}

Note: This project is currently setup with only 1 config file: jest-preset.js. I write all of my projects in Typescript with tsc with the same set of defaults. In the future, if I decide to make another configuration for something like Javascript, I may create a new jest preset and you will need to use a long form to find this config. Something like this: ./node_modules/@levibostian/jest-config/javascript/node.js
