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) @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 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 (#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 accurate moduleTypes paths resolved relative to the tsconfig.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 throwing ERR_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

Misc

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