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"
• 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 execute foo.ts See also: [TypeScript issue #37582](microsoft/TypeScript#37582)
  • If typechecking is disabled, you can also use source file extensions. E.g. import "./foo.ts"
• 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
• Adds diagnostics property to TSError, with array of TypeScript diagnostic objects from the compiler (API docs) (#1705, #1706) @​paulbrimicombe

Changed

• Renames option experimentalResolverFeatures to experimentalResolver (docs) (#1727) @​cspotcode
• Internal change to ESM loader for compatibility with forthcoming node versions: returns shortCircuit: true (#1714, #1715) @​cspotcode
• Performance: Optimize filesystem stat calls in ESM loader and new CommonJS resolver (#1758, #1759) @​cspotcode
• Performance, maintenance: Upgrade source-mapper dependency "@​cspotcode/source-map-support"
  • Switches to "trace-mapping" for underlying source-map parsing (#1729) @​cspotcode

Fixed

• Fixed bug where REPL .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

• 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
