## Error

```text
error TS2688: Cannot find type definition file for '@cloudflare/workers-types/2023-07-01'.
```

## 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).

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

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

```jsonc
// 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.

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