Added
--project

Added
- Added support for
module=NodeNext
,module=Node16
,.mts
,.cts
,.mjs
, and.cjs
file extensions (#1414, #1694, #1744, #1745, #1727, #1717, #1753, #1757) @cspotcode- For best results, enable
experimentalResolver
(docs) - 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"
- For best results, enable
- Added ability to include file extensions in CommonJS imports (#1727, #1753) @cspotcode
- Enables consistency with ESM, where file extensions are often mandatory
- Resolves from emitted to source file extensions (#1727, #1753) @cspotcode
- Must enable
experimentalResolver
, will be enabled by default in a future version (docs) - Typechecker requires importing the emitted file extension; ts-node resolves correctly to the source file. E.g.
import "./foo.js"
will executefoo.ts
See also: TypeScript issue #37582 - If typechecking is disabled, you can also use source file extensions. E.g.
import "./foo.ts"
- Must enable
- Added
experimentalSpecifierResolution
(#1727, #1753) @cspotcode- the same as Node's
--experimental-specifier-resolution
(Node docs) - 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
- the same as Node's
- Adds
diagnostics
property toTSError
, with array of TypeScript diagnostic objects from the compiler (API docs) (#1705, #1706) @paulbrimicombe
Changed

.type
command was not showing any type information when using TypeScript nightly builds (#1761, #1762) @cspotcode - Correctly suppress "Custom ESM Loaders" warning on newer node versions where the warning's prose changed (#1701) @cspotcode
- Fixed REPL bug where function signatures could not be entered across multiple lines (#1667, #1677) @d9k
- REPL treats unparenthesized object literals as objects, instead of as block scopes (#1697, #1699) @jhmaster2000
- Fixed bug where
preferTsExts
combined with third-party transpiler hooks could disruptnyc
code coverage (#1755) @cspotcode - Fixed bug where
file://
URLs in stack traces did not always use percent-encoding (#1738, #1726, #1729) @cspotcode - Fixed bug where v8-compile-cache-lib did not correctly unhook itself (#1717, #1718, #1719) @cspotcode
- This internal dependency is used to speed up loading the TypeScript compiler
Docs

v10.7.0
Questions about this release? Ask in the official discussion thread: #1680
Added
- Adds
--esm
flag, option, andts-node-esm
binary (#1258, #1655)- Enables full
esm
support; no need for--loader
norNODE_OPTIONS
- Use shebang
#!/usr/bin/env ts-node-esm
, runts-node --esm
, or add to your tsconfig.json:"ts-node": {"esm": true}
- Enables full
Changed
- Unflag ESM json modules on node >=17.5.0 (#1661, #1665) @Jamesernator
- no longer requires
--experimental-json-modules
- no longer requires
- Lazy-load dependencies to improve startup responsiveness. (#1676)
Fixed
- Fixed bug where "compiler", "transpiler", and swc backend would not resolve relative to the tsconfig.json that declared them (#1662, #1655)

v10.6.0...v10.7.0
https://github.com/TypeStrong/ts-node/milestone/11
v10.6.0
Questions about this release? Ask in the official discussion thread: #1666
Added
- Adds workaround for extensionless entrypoints with ESM loader (#1649, #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 - Some tools, for example
mocha
, have an extensionless entrypoint. (source, source) - Combining
NODE_OPTIONS=--loader ts-node/esm
with these tools causes this error. mochajs/mocha#4645 - node intends to fix this bug in a future release: nodejs/node#41711
- In the interim, we have implemented a workaround in ts-node.
- You can now combine tools such as
- Adds support for target "ES2022" in
moduleTypes
overrides (#1650)
Fixed
- Fixed bug where
--swc
and other third-party transpilers did not respectmoduleTypes
overrides (#1651, #1652, #1660) - Fixed bug where node flags were not preserved correctly in
process.execArgv
(#1657, #1658)- This affected
child_process.fork()
, since it usesprocess.execArgv
to create a similar child runtime. - With this fix,
child_process.fork()
will preserve both node flags andts-node
hooks.
- This affected
- Fixed compatibility TypeScript 4.7's API changes (#1647, #1648)
v10.5.0...v10.6.0
https://github.com/TypeStrong/ts-node/milestone/9
v10.5.0
Questions about this release? Ask in the official discussion thread: #1634
Added
- Eliminate "Emit Skipped" errors (#693, #1345, #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 usingconst enums
withpreserveConstEnums
disabled. - Fixes #693
- Avoids all "Emit Skipped" errors by performing a fallback
- Graduate swc transpiler out of experimental; add
swc: true
convenience option (docs) (#1487, #1536, #1613, #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, #1627)- global fallback only occurs when using a global installation of ts-node
- Add support for TypeScript's
traceResolution
output (docs) (#1128, #1491) @TheUnlocked - Support import assertions in ESM loader (docs) (#1557, #1558, #1559, #1573) @Pokute, @geigerzaehler
- Allows importing JSON files from ESM with the requisite flag (docs)
ts-node -vvv
also logs absolute paths tots-node
andtypescript
, to make it more obvious when you're accidentally using globally-installed versions (#1323, #1620)- Add swc target "es2022" (#1535, #1540)
- When you have target es2022 in tsconfig, will use swc's es2022 target
Changed
- Initialize TypeScript compiler before starting REPL prompt (#1498) @TheUnlocked
- Improves responsiveness for first line of REPL input
- Use
v8-compile-cache-lib
to load typescript - Support both
--camelCase
and--hyphen-case
for all CLI flags; update documentation to use--camelCase
(#1598, #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)
Fixed
- Fix #1538: REPL inputs fail to transpile via swc (#1538, #1541, #1602)
- Fix #1478: REPL erroneously logged
undefined
for all inputs after the first when using swc transpiler (#1478, #1580, #1602) - Fix #1389: In
--showConfig
output, emit accuratemoduleTypes
paths resolved relative to thetsconfig.json
which declared them (#1389, #1619) - Fix: Remove indentation from
ts-node --help
output (#1597, #1600) - Fix #1425: Merged definitions correctly into
tsconfig.schemastore-schema.json
(#1425, #1618) - Fix: Allow disabling
"use strict"
emit in SWC transpiler (#1531, #1537) - Fix: Add missing
ERR_UNKNOWN_FILE_EXTENSION
constructor; was throwingERR_UNKNOWN_FILE_EXTENSION is not a constructor
(#1562) @bluelovers - Fix #1565: entrypoint resolution failed on node v12.0.x and v12.1.x (#1565, #1566) @davidmurdoch
Docs

env -S
flag for shebangs (docs) (#1448, #1545) @sheeit, @chee - Suggest
skipIgnore
when you want to compile files in node_modules (docs) (#1553) @webstrand - Fix typo in
moduleTypes
on options page (docs) (#1630, #1633)
Misc
- Adds experimental
experimentalResolverFeatures
option, but it does not do anything yet (#1514, #1614)
v10.4.0...v10.5.0
https://github.com/TypeStrong/ts-node/milestone/4
v10.4.0
Added
- Adds support for targets "es2020" and "es2021" to swc transpiler (#1521)
- Adds automatic target downgrade when using older versions of swc (#1521)
- If tsconfig specifies es2020, but your version of swc only supports up to es2019, ts-node will automatically switch to es2019 instead of throwing an error
