`@types/bun` still conflicts with `@types/node` #8761

lgarron · 2024-02-07T19:06:39Z

What version of Bun is running?

1.0.25+a8ff7be64

What platform is your computer?

Darwin 23.2.0 arm64 arm

What steps can reproduce the bug?

mkdir /tmp/bun-node-types && cd /tmp/bun-node-types
bun init --yes
bun add @types/node @types/bun typescript
echo "{}" > tsconfig.json # Remove `skipLibCheck`
bun x tsc

What is the expected behavior?

TypeScript runs successfully.

What do you see instead?

Same issues as well

yolmcore · 2024-05-09T01:09:04Z

I got the error as well on Mac OS with @types/bun latest

KatFishSnake · 2024-05-13T18:27:47Z

Any workaround in a meantime? Would love to use bun:test 🙏

cc @Jarred-Sumner

polRk · 2024-06-02T12:44:59Z

Also different type for URL. i cant use URL with fetch...

Argument of type URL is not assignable to parameter of type string | Request | URL

This is a workaround for oven-sh/bun#8761 to allow our types to build.

piscopancer · 2024-07-14T07:55:02Z

still a bug

magick93 · 2024-08-07T02:26:55Z

I'm getting the same issues with a project that doesnt even use bun but is part of a pnpm / turborepo project, which includes a project that uses bun.

Does anyone have a solution?

michealroberts · 2024-08-20T16:49:22Z

Same issues in a very basic TypeScript project with bun ...

Joeghanoe · 2024-08-25T19:26:53Z

Same issue here, unable to use bun:test because of this... :(

cquasar · 2024-09-23T14:17:31Z

Also having trouble with it

lifenautjoe · 2024-10-03T15:09:09Z

Still happening :-(

Ollie1700 · 2024-10-14T12:12:21Z

~~We migrated to Bun on an older project that still builds with tsc -b on the build scripts. Adding tests folder to exclude in tsconfig.json worked for us:~~

Scratch that... As long as it's installed in node_modules the build fails ☹️

lgarron · 2024-11-14T23:44:55Z

This issue has gotten more severe, as it seems TypeScript now ships with @types/node built-in. So this now reproduces even if you don't explicitly include @types/node in your project:

mkdir /tmp/bun-node-types && cd /tmp/bun-node-types
bun init --yes
bun add @types/bun typescript
echo "{}" > tsconfig.json # Remove `skipLibCheck`
bun x tsc

As using tsc for type-checking can be rather important, this makes it really painful to use bun for any non-trivial project. This is the kind of thing that would be an immediate deal-breaker for me if I wasn't already a fan of bun's other benefits.

This issue has gotten more severe, as it seems TypeScript now ships with @types/node built-in. So this now reproduces even if you don't explicitly include @types/node in your project:

Actually, it's now even worse than I thought. Even "types": ["@types/bun"] and "skipLibCheck": true fail to prevent the issue. So the repro is now just:

mkdir /tmp/bun-node-types && cd /tmp/bun-node-types
bun init --yes
bun add @types/bun typescript
bun x tsc

It is literally impossible to use the TypeScript compiler and bun in the same repo using the default configuration from bun init.

@Jarred-Sumner, @nektro: Apologies for the direct ping, but I'd really appreciate a signal about what bun plans to do about this. This is no longer possible to work around at the level of individual projects.

alii · 2024-11-22T21:03:03Z

@lgarron are you able to put together a small reproduction repo? Copying those commands exactly above but not seeing any errors from TypeScript.

lgarron · 2024-11-22T23:02:57Z

@lgarron are you able to put together a small reproduction repo? Copying those commands exactly above but not seeing any errors from TypeScript.

Woah, it looks like that one is fixed with the latest versions!

But the original repro still holds:

mkdir /tmp/bun-node-types && cd /tmp/bun-node-types
bun init --yes
bun add @types/node @types/bun typescript
echo "{}" > tsconfig.json # Remove `skipLibCheck`
bun x tsc
