[Compare Source](https://togithub.com/TypeStrong/ts-node/compare/v10.7.0...v10.8.0)
Questions about this release? Ask in the official discussion thread: [#1767](https://togithub.com/TypeStrong/ts-node/issues/1767)
**Added**
- Added support for `module=NodeNext`, `module=Node16`, `.mts`, `.cts`, `.mjs`, and `.cjs` file extensions ([#1414](https://togithub.com/TypeStrong/ts-node/issues/1414), [#1694](https://togithub.com/TypeStrong/ts-node/issues/1694), [#1744](https://togithub.com/TypeStrong/ts-node/issues/1744), [#1745](https://togithub.com/TypeStrong/ts-node/issues/1745), [#1727](https://togithub.com/TypeStrong/ts-node/issues/1727), [#1717](https://togithub.com/TypeStrong/ts-node/issues/1717), [#1753](https://togithub.com/TypeStrong/ts-node/issues/1753), [#1757](https://togithub.com/TypeStrong/ts-node/issues/1757)) [@cspotcode](https://togithub.com/cspotcode)
- For best results, enable `experimentalResolver` ([docs](https://typestrong.org/ts-node/docs/options#experimentalresolver))
- See TypeScript's official documentation: https://www.typescriptlang.org/docs/handbook/esm-node.html
- enables mixed-mode projects with both ESM and CommonJS
- enables all supported file extensions in TypeScript 4.7
- Obeys package.json "type"
- Added ability to include file extensions in CommonJS imports ([#1727](https://togithub.com/TypeStrong/ts-node/issues/1727), [#1753](https://togithub.com/TypeStrong/ts-node/issues/1753)) [@cspotcode](https://togithub.com/cspotcode)
- Enables consistency with ESM, where file extensions are often mandatory
- Resolves from emitted to source file extensions ([#1727](https://togithub.com/TypeStrong/ts-node/issues/1727), [#1753](https://togithub.com/TypeStrong/ts-node/issues/1753)) [@cspotcode](https://togithub.com/cspotcode)
- Must enable `experimentalResolver`, will be enabled by default in a future version ([docs](https://typestrong.org/ts-node/docs/options#experimentalresolver))
- Typechecker requires importing the *emitted* file extension; ts-node resolves correctly to the *source* file. E.g. `import "./foo.js"` will execute `foo.ts` See also: [TypeScript issue #37582](https://togithub.com/microsoft/TypeScript/issues/37582)
- If typechecking is disabled, you can also use *source* file extensions. E.g. `import "./foo.ts"`
- Added `experimentalSpecifierResolution` ([#1727](https://togithub.com/TypeStrong/ts-node/issues/1727), [#1753](https://togithub.com/TypeStrong/ts-node/issues/1753)) [@cspotcode](https://togithub.com/cspotcode)
- the same as Node's `--experimental-specifier-resolution` ([Node docs](https://nodejs.org/dist/latest-v18.x/docs/api/esm.html#customizing-esm-specifier-resolution-algorithm))
- can also be specified in `tsconfig.json` for convenience, to avoid the CLI flag
- allows omitting file extensions in ESM imports, plus a few other CommonJS-style conveniences
- Adds `diagnostics` property to `TSError`, with array of TypeScript diagnostic objects from the compiler ([API docs](https://typestrong.org/ts-node/api/classes/TSError.html)) ([#1705](https://togithub.com/TypeStrong/ts-node/issues/1705), [#1706](https://togithub.com/TypeStrong/ts-node/issues/1706)) [@paulbrimicombe](https://togithub.com/paulbrimicombe)
**Changed**

- Internal change to ESM loader for compatibility with forthcoming node versions: returns `shortCircuit: true` ([#1714](https://togithub.com/TypeStrong/ts-node/issues/1714), [#1715](https://togithub.com/TypeStrong/ts-node/issues/1715)) [@cspotcode](https://togithub.com/cspotcode)
- Performance: Optimize filesystem stat calls in ESM loader and new CommonJS resolver ([#1758](https://togithub.com/TypeStrong/ts-node/issues/1758), [#1759](https://togithub.com/TypeStrong/ts-node/issues/1759)) [@cspotcode](https://togithub.com/cspotcode)

- Correctly suppress "Custom ESM Loaders" warning on newer node versions where the warning's prose changed ([#1701](https://togithub.com/TypeStrong/ts-node/issues/1701)) [@cspotcode](https://togithub.com/cspotcode)
- Fixed REPL bug where function signatures could not be entered across multiple lines ([#1667](https://togithub.com/TypeStrong/ts-node/issues/1667), [#1677](https://togithub.com/TypeStrong/ts-node/issues/1677)) [@d9k](https://togithub.com/d9k)
- REPL treats unparenthesized object literals as objects, instead of as block scopes ([#1697](https://togithub.com/TypeStrong/ts-node/issues/1697), [#1699](https://togithub.com/TypeStrong/ts-node/issues/1699)) [@jhmaster2000](https://togithub.com/jhmaster2000)

**Added**
- Adds `--esm` flag, option, and `ts-node-esm` binary ([#1258](https://togithub.com/TypeStrong/ts-node/issues/1258), [#1655](https://togithub.com/TypeStrong/ts-node/issues/1655))
- Enables full `esm` support; no need for `--loader` nor `NODE_OPTIONS`
- Use shebang `#!/usr/bin/env ts-node-esm`, run `ts-node --esm`, or add to your tsconfig.json: `"ts-node": {"esm": true}`
**Changed**
- Unflag ESM json modules on node >=17.5.0 ([#1661](https://togithub.com/TypeStrong/ts-node/issues/1661), [#1665](https://togithub.com/TypeStrong/ts-node/issues/1665)) [@Jamesernator](https://togithub.com/Jamesernator)

Questions about this release? Ask in the official discussion thread: [#1666](https://togithub.com/TypeStrong/ts-node/issues/1666)
**Added**
- Adds workaround for extensionless entrypoints with ESM loader ([#1649](https://togithub.com/TypeStrong/ts-node/issues/1649), [#1654](https://togithub.com/TypeStrong/ts-node/issues/1654))
- You can now combine tools such as `mocha` with `--loader ts-node/esm`, where previously node would throw `[ERR_UNKNOWN_FILE_EXTENSION]`
- node has a bug where combining `--loader` with an extensionless entrypoint causes this error [nodejs/node#33226](https://togithub.com/nodejs/node/issues/33226)
- Some tools, for example `mocha`, have an extensionless entrypoint. ([source](https://togithub.com/mochajs/mocha/blob/547ffd73535088322579d3d2026432112eae3d4b/package.json#L37), [source](https://togithub.com/mochajs/mocha/blob/547ffd73535088322579d3d2026432112eae3d4b/bin/mocha))
- Combining `NODE_OPTIONS=--loader ts-node/esm` with these tools causes this error. [mochajs/mocha#4645](https://togithub.com/mochajs/mocha/issues/4645)
- node intends to fix this bug in a future release: [nodejs/node#41711](https://togithub.com/nodejs/node/issues/41711)
- In the interim, we have implemented a workaround in ts-node.
- Adds support for target "ES2022" in `moduleTypes` overrides ([#1650](https://togithub.com/TypeStrong/ts-node/issues/1650))
**Fixed**
- Fixed bug where `--swc` and other third-party transpilers did not respect `moduleTypes` overrides ([#1651](https://togithub.com/TypeStrong/ts-node/issues/1651), [#1652](https://togithub.com/TypeStrong/ts-node/issues/1652), [#1660](https://togithub.com/TypeStrong/ts-node/issues/1660))
- Fixed bug where node flags were not preserved correctly in `process.execArgv` ([#1657](https://togithub.com/TypeStrong/ts-node/issues/1657), [#1658](https://togithub.com/TypeStrong/ts-node/issues/1658))
- This affected `child_process.fork()`, since it uses `process.execArgv` to create a similar child runtime.
- With this fix, `child_process.fork()` will preserve both node flags and `ts-node` hooks.
- Fixed compatibility TypeScript 4.7's API changes ([#1647](https://togithub.com/TypeStrong/ts-node/issues/1647), [#1648](https://togithub.com/TypeStrong/ts-node/issues/1648))

Questions about this release? Ask in the official discussion thread: [#1634](https://togithub.com/TypeStrong/ts-node/issues/1634)
**Added**
- Eliminate "Emit Skipped" errors ([#693](https://togithub.com/TypeStrong/ts-node/issues/693), [#1345](https://togithub.com/TypeStrong/ts-node/issues/1345), [#1629](https://togithub.com/TypeStrong/ts-node/issues/1629))
- Avoids all "Emit Skipped" errors by performing a fallback `transpileOnly`-style transformation.
- Does not affect typechecking. Type errors are still detected and thrown.
- Fallback has the same limitations as `isolatedModules`. This will only affect rare cases such as using `const enums` with `preserveConstEnums` disabled.
- Fixes [#693](https://togithub.com/TypeStrong/ts-node/issues/693)
- Graduate swc transpiler out of experimental; add `swc: true` convenience option ([docs](https://typestrong.org/ts-node/docs/transpilers)) ([#1487](https://togithub.com/TypeStrong/ts-node/issues/1487), [#1536](https://togithub.com/TypeStrong/ts-node/issues/1536), [#1613](https://togithub.com/TypeStrong/ts-node/issues/1613), [#1627](https://togithub.com/TypeStrong/ts-node/issues/1627))
- `"swc": true` or `--swc` will use swc for faster execution
- This feature is no longer marked "experimental." Thank you to everyone who filed bugs!
- swc transpiler attempts to load `@swc/core` or `@swc/wasm` dependencies from your project before falling-back to global installations ([#1613](https://togithub.com/TypeStrong/ts-node/issues/1613), [#1627](https://togithub.com/TypeStrong/ts-node/issues/1627))
- global fallback only occurs when using a global installation of ts-node
- Add support for TypeScript's `traceResolution` output ([docs](https://www.typescriptlang.org/tsconfig/#traceResolution)) ([#1128](https://togithub.com/TypeStrong/ts-node/issues/1128), [#1491](https://togithub.com/TypeStrong/ts-node/issues/1491)) [@TheUnlocked](https://togithub.com/TheUnlocked)
- Support import assertions in ESM loader ([docs](https://nodejs.org/dist/latest-v17.x/docs/api/esm.html#import-assertions)) ([#1557](https://togithub.com/TypeStrong/ts-node/issues/1557), [#1558](https://togithub.com/TypeStrong/ts-node/issues/1558), [#1559](https://togithub.com/TypeStrong/ts-node/issues/1559), [#1573](https://togithub.com/TypeStrong/ts-node/issues/1573)) [@Pokute](https://togithub.com/Pokute), [@geigerzaehler](https://togithub.com/geigerzaehler)
- Allows importing JSON files from ESM with the requisite flag ([docs](https://nodejs.org/dist/latest-v17.x/docs/api/esm.html#json-modules))
- `ts-node -vvv` also logs absolute paths to `ts-node` and `typescript`, to make it more obvious when you're accidentally using globally-installed versions ([#1323](https://togithub.com/TypeStrong/ts-node/issues/1323), [#1620](https://togithub.com/TypeStrong/ts-node/issues/1620))
- Add swc target "es2022" ([#1535](https://togithub.com/TypeStrong/ts-node/issues/1535), [#1540](https://togithub.com/TypeStrong/ts-node/issues/1540))
- When you have target es2022 in tsconfig, will use swc's es2022 target
**Changed**
- Initialize TypeScript compiler before starting REPL prompt ([#1498](https://togithub.com/TypeStrong/ts-node/issues/1498)) [@TheUnlocked](https://togithub.com/TheUnlocked)
- Improves responsiveness for first line of REPL input
- Use `v8-compile-cache-lib` to load typescript
- improves startup time ([#1339](https://togithub.com/TypeStrong/ts-node/issues/1339), [#1603](https://togithub.com/TypeStrong/ts-node/issues/1603))
- Support both `--camelCase` and `--hyphen-case` for all CLI flags; update documentation to use `--camelCase` ([#1598](https://togithub.com/TypeStrong/ts-node/issues/1598), [#1599](https://togithub.com/TypeStrong/ts-node/issues/1599))
- Not a breaking change; CLI continues to accept both forms
- Make `TSError` `diagnosticText` property non-enumerable to prevent it from being logged below the stack ([#1632](https://togithub.com/TypeStrong/ts-node/issues/1632))
**Fixed**
- Fix [#1538](https://togithub.com/TypeStrong/ts-node/issues/1538): REPL inputs fail to transpile via swc ([#1538](https://togithub.com/TypeStrong/ts-node/issues/1538), [#1541](https://togithub.com/TypeStrong/ts-node/issues/1541), [#1602](https://togithub.com/TypeStrong/ts-node/issues/1602))
