Property 'default' does not exist on type 'CacheStorage'

I am seeing a typescript error for let response = await caches.default.match(req); which shows Property 'default' does not exist on type 'CacheStorage'. ts(2339) It seems to be using the CacheStorage definition from /node_modules/typescript/lib/lib.dom.d.ts instead of @cloudflare/workers-types

My tsconfig is pretty simple:

{
  "compilerOptions": {
    "target": "ES2020",
    "module": "CommonJS",
    "lib": [
      "ES2020"
    ],
    "types": [
      "@cloudflare/workers-types"
    ]
  }
}

{
  "compilerOptions": {
    "target": "ES2020",
    "module": "CommonJS",
    "lib": [
      "ES2020"
    ],
    "types": [
      "@cloudflare/workers-types"
    ]
  }
}

The suggestion mentioned here https://discord.com/channels/595317990191398933/779390076219686943/1014614267858788412 to switch lib did not resolve my issue 😥

Unfortunately that does not resolve my issue either

Try reloading VSCode. Sometimes the TS server gets stuck…

u0•2y ago

Issue still persists with a reload of VSCode, restarted my language servers as well. Maybe it would be helpful to look at my repo? Specific lines are at https://github.com/udiaca/u0.vc/blob/e7b61c6a9a4626aa7ba32cbe2a8748db69bd5839/functions/opt/%5B%5Bpath%5D%5D.ts#L5-L14 and https://github.com/udiaca/u0.vc/blob/investigate-caches-default/src/utils/caches.ts

Ok, found your issue... Do you want it as a PR to your repo?

u0•2y ago

Whatever is easiest, maybe type out here so other people can find in discord search?

Hello, I’m Allie!•2y ago

So the main issue is that you didn't have an include field in your tsconfig, which applies the types to the directory.

u0•2y ago

not sure I follow, not having an include defined within the tsconfig should have the following behaviour:

Specifies a list of glob patterns that match files to be included in compilation. If no 'files' or 'include' property is present in a tsconfig.json, the compiler defaults to including all files in the containing directory and subdirectories except those specified by 'exclude'. Requires TypeScript version 2.0 or later.

I added an "include": ["**/*"] but still see a type error within VSCode

Checked out your changes, restarted VSCode

Hello, I’m Allie!•2y ago

What node version are you on? Also, try a clean node_modules install

u0•2y ago

node --version
v16.15.1

node --version
v16.15.1

Okay, will remove node_modules and reinstall everything

Hello, I’m Allie!•2y ago

Probably isn't the issue, but it is working on v19.0.0. Let me try downgrading...

u0•2y ago

I upgraded to node 18.12.0 and 19.0.0 but I still see this error 🤷

Hello, I’m Allie!•2y ago

Can you replicate it on a different device? I got the issue to pop up, but only before I changed the tsconfig.

u0•2y ago

Hmmm, with your tsconfig changes and the following devcontainer, "image":"mcr.microsoft.com/devcontainers/typescript-node:16-bullseye" the error goes away. Wonder what's up with my environment. Thank you for all of your help @HardAtWork 🥂
