presets

presets holds every preset as a plain config object. Each value is the same object the @repobuddy/jest/presets/<name> entry exports as its default.

import { presets } from '@repobuddy/jest'

Use it to read a preset’s values or to spread one into a config. To apply a preset, the preset key with the entry path is the usual way.

Behavior

Importing the main entry evaluates every preset. ts, tsWatch, jsdomTs, and jsdomTsWatch read package.json from the working directory, and every preset except watch checks for the source folder there.
The values are shared objects. Copy before you change one: { ...presets.tsEsm, roots: ['<rootDir>/lib'] }.

Examples

Read a preset’s moduleNameMapper and extend it:

import { presets } from '@repobuddy/jest'

export default {
  ...presets.tsEsm,
  moduleNameMapper: {
    ...presets.tsEsm.moduleNameMapper,
    '^#utils$': '<rootDir>/src/utils.ts',
  },
}

The single-preset entry gives the same object:

import tsEsm from '@repobuddy/jest/presets/ts-esm'
