error TS2688: Cannot find type definition file for '@cloudflare/workers-types/2023-07-01' — v5 removed dated entrypoints

Fix

Recommended — generate types matching your compatibility_date/flags and bindings:

npx wrangler types          # writes worker-configuration.d.ts (also generates Env)

// tsconfig.json — before
{ "compilerOptions": { "types": ["@cloudflare/workers-types/2023-07-01"] } }
// after
{ "compilerOptions": { "types": ["./worker-configuration.d.ts"] } }
// with nodejs_compat also install @types/node and add "node"
{ "compilerOptions": { "types": ["./worker-configuration.d.ts", "node"] } }

Then remove imports from @cloudflare/workers-types in Worker code and re-run wrangler types whenever bindings or the compatibility date change. Minimal fix if you keep the package (e.g. for a shared library): use the undated "@cloudflare/workers-types" entrypoint, which works on both v4 and v5.

Symptom

After a dependency bump of @cloudflare/workers-types from 4.x to 5.x (often a Dependabot/Renovate PR), tsc fails:

error TS2688: Cannot find type definition file for '@cloudflare/workers-types/2023-07-01'.
  Entry point of type library '@cloudflare/workers-types/2023-07-01' specified in compilerOptions

Many templates and older answers put a dated path (e.g. 2022-11-30, 2023-03-01, 2023-07-01) in tsconfig.json compilerOptions.types.

Cause

@cloudflare/workers-types v5 (Cloudflare changelog 2026-07-03) "simplifies the package to expose only the latest runtime types". Only two entrypoints remain: @cloudflare/workers-types (latest compatibility date + stable flags) and @cloudflare/workers-types/experimental. Dated entrypoints were removed. Date-pinned types now come from wrangler types (runtime type generation in Wrangler v4).

Verify

npx tsc --noEmit passes; worker-configuration.d.ts declares your Env bindings.
