#### BREAKING CHANGES
- By default, `ts-jest` will use `sourceMap` option from your `tsconfig`. If users want to have sourcemap on, they need to set `sourceMap: true` in `tsconfig`.
- follow Jest support Node engines ([#2478](https://togithub.com/kulshekhar/ts-jest/pull/2478)) ([1fecf7f](https://togithub.com/kulshekhar/ts-jest/commit/1fecf7ff92a5f1a0cc6ea1d27026f9f54a3d5ead))
- add `exports` field to `package.json`, see https://nodejs.org/api/packages.html#packages_package_entry_points ([#2467](https://togithub.com/kulshekhar/ts-jest/pull/2467)) ([d3aba3e](https://togithub.com/kulshekhar/ts-jest/commit/d3aba3e103f85b3a42d0e2ecaea9d3457917319e))
- `ts-jest` custom AST transformer function signature has changed to
import type { TsCompilerInstance } from 'ts-jest/dist/types'
export function factory(compilerInstance: TsCompilerInstance) {
//...
}
- One is currently using `pathRegex` should use `exclude` with `glob` patterns.
- If one currently relies on type check for `js` files, please set `checkJs: true` in your tsconfig.
- Now both `isolatedModules: true` and `isolatedModule: false` codes are in one single class `TsCompiler` which is an instance created in `TsJestCompiler` based on config option `compiler` with value `typescript` or `ttypescript`.
- **config:** `packageJson` config option is not used in internal `ts-jest` so this option is now removed.
- **config:** One is defining ast transformers in `jest.config.js`/`package.json` should change to
// jest.config.js
module.exports = {
//...
globals: {
'ts-jest': {
astTransformers: {
before: ['your_before_transformer_path'],
after: ['your_after_transformer_path'],
afterDeclarations: ['your_afterDeclarations_transformer_path'],
}
}
}
}
or
// package.json
{
"jest": {
"globals": {
"ts-jest": {
"astTransformers": {
"before": ["your_before_transformer_path"],
"after": ["your_after_transformer_path"],
"afterDeclarations": ["your_afterDeclarations_transformer_path"]
}
}
}
}
}
- One currently refers type in `jest.config.js`
/** @typedef {import('ts-jest')} */
module.exports = {
//...
}
should change to
/** @typedef {import('ts-jest/dist/types')} */
module.exports = {
//...
}
- Remove possibilities to import `mocked`, `createJestPreset`, `pathsToModuleNameMapper` from package entry. One should change to
import { mocked, createJestPreset, pathsToModuleNameMapper } from 'ts-jest/utils'
- **config:** One currently uses `tsConfig` should change to `tsconfig` in your `jest.config.js` or `package.json`.
#### [26.5.6](https://togithub.com/kulshekhar/ts-jest/compare/v26.5.5...v26.5.6) (2021-05-05)
##### Code Refactoring
- refactor(config): show warning message for `sourceMap: false` ([#2557](https://togithub.com/kulshekhar/ts-jest/pull/2557)) ([cf60990](https://togithub.com/kulshekhar/ts-jest/commit/cf609900e2c5937755123bd08ca2c5f2ff5e0651)).

By default, `ts-jest` will use `sourceMap` option from your `tsconfig`. If users want to have sourcemap on, they need to set `sourceMap: true` in `tsconfig`. - follow Jest support Node engines ([#2478](https://togithub.com/kulshekhar/ts-jest/pull/2478)) ([1fecf7f](https://togithub.com/kulshekhar/ts-jest/commit/1fecf7ff92a5f1a0cc6ea1d27026f9f54a3d5ead)) - add `exports` field to `package.json`, see https://nodejs.org/api/packages.html#packages_package_entry_points ([#2467](https://togithub.com/kulshekhar/ts-jest/pull/2467)) ([d3aba3e](https://togithub.com/kulshekhar/ts-jest/commit/d3aba3e103f85b3a42d0e2ecaea9d3457917319e)) - `ts-jest` custom AST transformer function signature has changed to import type { TsCompilerInstance } from 'ts-jest/dist/types' export function factory(compilerInstance: TsCompilerInstance) { //... } - One is currently using `pathRegex` should use `exclude` with `glob` patterns. - If one currently relies on type check for `js` files, please set `checkJs: true` in your tsconfig. - Now both `isolatedModules: true` and `isolatedModule: false` codes are in one single class `TsCompiler` which is an instance created in `TsJestCompiler` based on config option `compiler` with value `typescript` or `ttypescript`. - **config:** `packageJson` config option is not used in internal `ts-jest` so this option is now removed. - **config:** One is defining ast transformers in `jest.config.js`/`package.json` should change to // jest.config.js module.exports = { //... globals: { 'ts-jest': { astTransformers: { before: ['your_before_transformer_path'], after: ['your_after_transformer_path'], afterDeclarations: ['your_afterDeclarations_transformer_path'], } } } } or // package.json { "jest": { "globals": { "ts-jest": { "astTransformers": { "before": ["your_before_transformer_path"], "after": ["your_after_transformer_path"], "afterDeclarations": ["your_afterDeclarations_transformer_path"] } } } } } - One currently refers type in `jest.config.js` /** @typedef {import('ts-jest')} */ module.exports = { //... } should change to /** @typedef {import('ts-jest/dist/types')} */ module.exports = { //... } - Remove possibilities to import `mocked`, `createJestPreset`, `pathsToModuleNameMapper` from package entry. One should change to import { mocked, createJestPreset, pathsToModuleNameMapper } from 'ts-jest/utils' - **config:** One currently uses `tsConfig` should change to `tsconfig` in your `jest.config.js` or `package.json`. #### [26.5.6](https://togithub.com/kulshekhar/ts-jest/compare/v26.5.5...v26.5.6) (2021-05-05) ##### Code Refactoring - refactor(config): show warning message for `sourceMap: false` ([#2557](https://togithub.com/kulshekhar/ts-jest/pull/2557)) ([cf60990](https://togithub.com/kulshekhar/ts-jest/commit/cf609900e2c5937755123bd08ca2c5f2ff5e0651)).Configuration
