TypeScript 6.0 release notes breaking changes

💡 Result:

TypeScript 6.0, released on March 23, 2026, serves as a significant transition release designed to prepare developers for TypeScript 7.0, which will introduce a native port of the compiler [1][2][3]. While TypeScript 6.0 maintains API compatibility with version 5.9, it introduces several breaking changes and deprecations [1][2]. Important Migration Note: To ease the transition, deprecations in TypeScript 6.0 can be temporarily ignored by setting "ignoreDeprecations": "6.0" in your tsconfig.json [1][2][4]. However, these options will be removed entirely in TypeScript 7.0 [1][5]. Key Breaking Changes and Default Shifts: - Strict Mode: "strict" now defaults to true [1][2][6]. - Module Format: "module" now defaults to "esnext" [3][6]. - ECMAScript Target: "target" now defaults to "es2025" [3][6]. - Module Resolution: "moduleResolution" now defaults to "bundler" [3]. The "classic" resolution strategy is removed entirely [6]. - Type Defaults: "types" now defaults to an empty array ([]) [1][2][6]. - Project Root: "rootDir" now defaults to the directory containing your tsconfig.json, rather than the computed source root [3][6][5]. - Library Imports: "noUncheckedSideEffectImports" now defaults to true [3][6]. - Import Settings: "esModuleInterop" and "allowSyntheticDefaultImports" are now always enabled [2][6]. Deprecated Features: The following features are deprecated and will be removed in TypeScript 7.0 [1][2]: - target: "es5" [1][2][6] - --moduleResolution node (use "node10" or "bundler" instead) [1][2][5] - --moduleResolution classic [1][2][6] - --downlevelIteration [2] - --baseUrl [2][5] - --esModuleInterop false and --allowSyntheticDefaultImports false [2] - --alwaysStrict false [2][5] - outFile [2][5] - asserts keyword on imports [2][5] - no-default-lib directives [2][5] Additionally, using AMD, UMD, or System module formats will now trigger compiler errors [6]. Specifying files via the command line when a tsconfig.json exists is also now an error [5].

TypeScript 6.x bump breaks web typecheck—fix baseUrl deprecation in tsconfig first.

TypeScript 6.0 introduces breaking changes/deprecations, and with "typescript": "~6.0.3" the web build fails in web/tsconfig.app.json(28,5) with TS5101 (“Option 'baseUrl' is deprecated… Specify 'ignoreDeprecations': '6.0' to silence”). Update web/tsconfig.app.json to migrate away from baseUrl (or add "ignoreDeprecations": "6.0" as an unblocker) so npm run typecheck / make check-web passes.

Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

In `@web/package.json` at line 83, The tsconfig currently triggers TS5101 because
"baseUrl" is deprecated under TypeScript 6.0; open the project's
tsconfig.app.json and under "compilerOptions" either remove/migrate the
"baseUrl" usage (replace with explicit "paths" mappings if needed) or add the
temporary unblocker "ignoreDeprecations": "6.0" so the typecheck passes; ensure
you update the "baseUrl" key and/or add "ignoreDeprecations" in the same
"compilerOptions" object to resolve the error.
