error TS5110: Option 'module' must be set to 'NodeNext'

when option 'moduleResolution' is set to 'NodeNext'.

Not confirmed yet · posted

Cause

since TS 5.2 node16/nodenext resolution is accepted only with a matching Node module setting; module esnext, commonjs or the default no longer pair with it.

Fix

risk: low

// code that Node runs directly (the tsc output is executed by node):-  "module": "ESNext",+  "module": "NodeNext",      // implies moduleResolution NodeNext; drop that line// code a bundler consumes (Vite, webpack, esbuild): keep "module": "ESNext"// and set "moduleResolution": "Bundler" instead

Don’t try

"moduleResolution": "node" (node10) — silences TS5110 but ignores package.json "exports"; node10 is deprecated in TS 6.0 and rejected by TS 7.0.

pin TypeScript back to 5.1 — only hides the mismatch the 5.2 check exposed (Node-style resolution with non-Node emit); TS 6 and 7 enforce the same rule.
