v10.8.0...v10.8.1
github.com/TypeStrong/ts-node/milestone/14

Questions about this release? Ask in the official discussion thread

Added

• Added support for module=NodeNext, module=Node16, .mts, .cts, .mjs, and .cjs file extensions (#1414, #1694, #1744, #1745, #1727, #1717, #1753, #1757)

  • For best results, enable experimentalResolver (docs)

  • See TypeScript's official documentation: 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, #1753)

  • Enables consistency with ESM, where file extensions are often mandatory

• Resolves from emitted to source file extensions (#1727, #1753)

  • 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 execute foo.ts See also: TypeScript issue #37582

  • If typechecking is disabled, you can also use source file extensions. E.g. import "./foo.ts"

• Added experimentalSpecifierResolution (#1727, #1753)

  • 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

• Adds diagnostics property to TSError, with array of TypeScript diagnostic objects from the compiler (API docs) (#1705, #1706)

Changed

• Renames option experimentalResolverFeatures to experimentalResolver (docs)

• Internal change to ESM loader for compatibility with forthcoming node versions: returns shortCircuit: true (#1714, #1715)

Fixed

• Fixed bug where REPL .type command was not showing any type information when using TypeScript nightly builds (#1761, #1762)

• Correctly suppress "Custom ESM Loaders" warning on newer node versions where the warning's prose changed

• Fixed REPL bug where function signatures could not be entered across multiple lines (#1667, #1677)

• REPL treats unparenthesized object literals as objects, instead of as block scopes (#1697, #1699)

• Fixed bug where preferTsExts combined with third-party transpiler hooks could disrupt nyc code coverage

• Fixed bug where file:// URLs in stack traces did not always use percent-encoding (#1738, #1726, #1729)

• Fixed bug where v8-compile-cache-lib did not correctly unhook itself (#1717, #1718, #1719)

  • This internal dependency is used to speed up loading the TypeScript compiler

Docs

• Many docs improvements

v10.7.0...v10.8.0
github.com/TypeStrong/ts-node/milestone/12

Questions about this release? Ask in the official discussion thread

Added

• Adds --esm flag, option, and ts-node-esm binary (#1258, #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

  • Enables reusable tsconfig.json shared via node module to include necessary dependencies

v10.6.0...v10.7.0
github.com/TypeStrong/ts-node/milestone/11

Questions about this release? Ask in the official discussion thread

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.

• Adds support for target "ES2022" in moduleTypes overrides

Fixed

• Fixed bug where --swc and other third-party transpilers did not respect moduleTypes 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 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, #1648)

v10.5.0...v10.6.0
github.com/TypeStrong/ts-node/milestone/9

Questions about this release? Ask in the official discussion thread

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 using const enums with preserveConstEnums disabled.

  • Fixes #693

• 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)

• Support import assertions in ESM loader (docs) (#1557, #1558, #1559, #1573)

  • Allows importing JSON files from ESM with the requisite flag (docs)

• 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, #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

  • Improves responsiveness for first line of REPL input

• Use v8-compile-cache-lib to load typescript

  • improves startup time (#1339, #1603)

• 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

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 accurate moduleTypes paths resolved relative to the tsconfig.json which declared them (#1389, #1619)

• Remove indentation from ts-node --help output (#1597, #1600)

• Fix #1425: Merged definitions correctly into tsconfig.schemastore-schema.json (#1425, #1618)

• Allow disabling "use strict" emit in SWC transpiler (#1531, #1537)

• Add missing ERR_UNKNOWN_FILE_EXTENSION constructor; was throwing ERR_UNKNOWN_FILE_EXTENSION is not a constructor

• Fix #1565: entrypoint resolution failed on node v12.0.x and v12.1.x (#1565, #1566)

Misc

• Adds experimental experimentalResolverFeatures option, but it does not do anything yet (#1514, #1614)

v10.4.0...v10.5.0
github.com/TypeStrong/ts-node/milestone/4

Added

• Adds support for targets "es2020" and "es2021" to swc transpiler

• Adds automatic target downgrade when using older versions of swc

  • 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

Changed

• Improves types and API docs for creatEsmHooks (API docs) (#1506, #1529)

Fixed

• Fix #1526: data URL handling in new ESM loader hooks API (#1526, #1529)

v10.3.1...v10.4.0
github.com/TypeStrong/ts-node/milestone/8

Fixed

• Add version check to use new loader hooks API for node >=16.12.0

v10.3.0...v10.3.1
github.com/TypeStrong/ts-node/milestone/7

Questions about this release? Ask in the official discussion thread

Added

• Declare types for node builtin modules within REPL so you do not need to import them (#1424, #1500)

  • Node REPL exposes builtin modules as globals; typechecker now understands this

  • Typechecking should no longer raise errors when using builtins without first importing

  • For example: util.promisify(setTimeout)(1000) or fs.readFileSync('example.txt')

• Add createEsmHooks() function to create ESM loader hooks (API docs)

  • Can be used to compose our loader hooks with another loader or additional logic

• register() accepts a ts-node Service (API docs)

  • register(options) is still supported; no breaking changes

• Add support for Node.js's new loader hooks API (#1372, #1457, #1007)

  • Node.js has changed their loader hooks API

  • ts-node is compatible with all node versions, detects your node version and exposes the correct hooks API

  • Node's new API currently only available in node v17 nightly builds

  • Node will eventually backport the changes to node 16, and may also be backport to 14 and 12

• Add --emit to --help output (#1400, #1484)

Changed

• When ts-node is registered and other libraries require('source-map-support'), they will be redirected to @cspotcode/source-map-support

  • See complete description in Fixed section below

Fixed

• Fix #1440, #1441, #1438, #1495: Incorrect stack traces when third-party libraries use source-map-support instead of @cspotcode/source-map-support (#1440, #1441, #1438, #1495, cspotcode/node-source-map-support#23, #1496, #1497)

  • When ts-node is registered and other libraries require('source-map-support'), they will be redirected to @cspotcode/source-map-support

  • ts-node uses @cspotcode/source-map-support for the fixes and enhancements listed here: @cspotcode/source-map-support changelog

  • To ensure correct stack traces, all libraries must share a compatible sourcemap support implementation

• Fix #1363: REPL may erroneously combine previous input with next input, eval both as a single statement (#1363, #1480)

  • For example, entering 100 on first line and * 2 on second line would erronously be interpreted as 100 * 2

  • REPL now ensures both lines are separate statements, both when typechecking and when evaluating

• Fix #1488: Node may log "circular dependency" warning when using allowJs (#1488, #1489)

• Fix #1301: Filter empty strings from TS_NODE_IGNORE and TS_NODE_IGNORE_DIAGNOSTICS; treat empty environment variable as empty array (#1301, #1483)

  • TS_NODE_IGNORE= ts-node ./example.ts will disable default ignore rules; will compile files in ./node_modules

Docs

• Update VSCode debug configuration (Docs)

• Update ESM-related messaging to clarify that experimental status is due to Node.js, not ts-node

• Refer to ts-node consistently

v10.2.1...v10.3.0
github.com/TypeStrong/ts-node/milestone/5

Fixed

• Fixes #1426: Do not import typescript outside of configuration/project loading (#1433, #1426)

  • We take care to load your project's version of typescript, falling back to a globally-installed version if necessary.

  • 10.2.0 introduced a bug where we did not do this consistently, causing global or npx installations of ts-node to attempt loading typescript relative to themselves, not your project.

  • This failed if typescript was not globally installed or npx did not install peer dependencies.

v10.2.0...v10.2.1
github.com/TypeStrong/ts-node/milestone/6

Questions about this release? Ask in the official discussion thread

Added

• Adds top-level await support to REPL (#1383, #245)

  • can be disabled with --no-experimental-repl-await, experimentalReplAwait, or TS_NODE_EXPERIMENTAL_REPL_AWAIT (CLI docs, API docs)

• Setting "pretty": false disables pretty formatting of diagnostics even when stdout is a TTY (#1418, #1420)

  • Applies to ts-node's pretty option, not to be confused with TypeScript's pretty option

• Ignores diagnostics which are annoying in an interactive REPL (#1396, #1120, #729, #850, #469)

  • For example, when you input const foo = 1 in the REPL, foo is unused. We ignore the resulting diagnostic foo is declared but its value is never read

  • Diagnostics are only ignored in the REPL

  • Diagnostics for non-REPL files imported by the REPL will still be shown

• Logged stack traces are colorized to match vanilla node's behavior (#1412, #1405)

Fixed

• Fix #1397: SWC transpiler should emit ECMAScript imports and exports when configuration dictates (#1409, #1397)

  • Enables SWC transpiler to be used alongside --loader

• Fix #1403: source-map-support breaks rendering of node errors (#1405, #1403)

• Fix #1410: rendering of async stack frames should include async annotations (#1405, #1410)

• Fix #1411: wrong order of process 'exit' event and logging unhandled exception (#1405, #1411)

• Fix #1419: Should not throw require.resolve error when @types/node peerDependency is missing (#1419, #1422)

v10.1.0...v10.2.0
github.com/TypeStrong/ts-node/milestone/2

Questions about this release? Ask in the official discussion thread

Added

• Add "moduleType" option to override module type -- CommonJS or ECMAScript -- on select files. (docs) (#1342, #1371, #1376)

  • Useful when a configuration file, for example webpack.config.ts, must execute as CommonJS but the rest of the project is ESM

  • selectively overrides package.json "type" and tsconfig.json "module"

  • akin to .cjs and .mjs extensions, but for .ts and .tsx files

• Implement "extends" support for "ts-node" options in tsconfig.json (#1328, #1356)

  • "ts-node": {} options will be parsed from extended tsconfigs

  • allows sharing and deduplicating ts-node configuration

• Un-deprecate scope and scopeDir; add both to CLI and tsconfig.json options; un-deprecate TS_NODE_SCOPE env var; add TS_NODE_SCOPE_DIR env var (docs) (#1346, #1367)

Changed

• Improve error messages thrown by native ESM loader hooks (#1357, #1373)

  • messages more closely match node; are more descriptive

• Emit "ts-node" object at the top of --showConfig output instead of the bottom

Fixed

• Fix #1282: Set correct globals in [stdin], [eval], and <repl> contexts

  • More closely align ts-node's behavior with vanilla node

  • Affects the interactive REPL, piping to stdin, and ts-node -e

  • Matches node's behavior for globals __filename, __dirname, module and sub-fields of module, exports, and builtin module aliases fs, etc

• Fix #1343: Set swc option keepClassNames to true

• #1387: REPL outputs 'use strict' after first empty line of input

Docs

• Update ESM docs to say that env vars are supported with node --loader ts-node/esm (docs)

Breaking changes are prefixed with [BREAKING]

Added

• Adds --show-config to log the resolved configuration (docs) (#1100, #1243)

• Bundle and re-export @tsconfig/node* configurations for convenience (docs) (#1202, #1236, #1313)

• Default to appropriate @tsconfig/node* configuration based on node and typescript versions (docs) (#1202, #1236, #1313)

• Automatically reference @types/node; use globally-installed @types/node if not locally installed (#1240, #1257)

• Add swc integration and new --transpiler option to use third-party transpilers for a massive speed boost on large codebases (docs) (#779, #1160)

• Add --cwd-mode and ts-node-cwd to resolve config file relative to cwd, not entrypoint script

Changed

• breaking

  **** Make --script-mode default behavior; resolve tsconfig relative to entrypoint script instead of cwd (#949, #1197, #1155)

  • In most cases this change will have no noticeable effect

  • Primarily benefits portable shell scripts on your $PATH, because ts-node will respect the script's local tsconfig.json

  • Use --cwd-mode or ts-node-cwd if you need legacy behavior

• breaking

  **** ignore rules evaluate relative to tsconfig.json directory, otherwise cwd

• breaking

  **** Remove support for node 10. Minimum supported version is node 12

• Rename --dir to --cwd; rename TS_NODE_DIR to TS_NODE_CWD

  • --dir and TS_NODE_DIR are deprecated but still parsed for backwards-compatibility

  • --dir effectively changed the working directory of ts-node; renaming makes this behavior more obvious

Deprecated

• deprecated

  Deprecate TS_NODE_SCOPE

• deprecated

  Deprecate --dir and TS_NODE_DIR

Removed

• breaking

  **** Internal APIs removed from type declarations

  • Removed DEFAULTS, normalizeSlashes, parse, split

  • This aligns our behavior with vanilla node

• breaking

  **** Fix #1225: compiler is loaded relative to tsconfig.json instead of entrypoint script

  • In most cases this change will have no noticable effect

• Fix #1217: REPL not always using passed stdout and stderr

• Fix #1220: ts-node ./index may execute the wrong file extension because tsconfig search poisons the require.resolve cache

• Fix #1322: Sourcemaps fail for filenames with spaces or other characters which are percent-encoded in URLs (#1160, #1330)

• Fix #1331: Resolution of node builtin modules in ESM loader fails on node >=12.20.0, <13
