Please fill in this template.

Use a meaningful title for the pull request. Include the name of the package modified.
Test the change in your own code. (Compile and run.)
Add or edit tests to reflect the change.
Follow the advice from the readme.
Avoid common mistakes.
Run npm test <package to test>.

Select one of these and delete the others:

If adding a new definition:

The package does not already provide its own types, or cannot have its .d.ts files generated via --declaration
If this is for an npm package, match the name. If not, do not conflict with the name of an npm package.
Create it with dts-gen --dt, not by basing it on an existing project.
Represents shape of module/library correctly
tslint.json should contain { "extends": "@definitelytyped/dtslint/dt.json" }, and no additional rules.
tsconfig.json should have noImplicitAny, noImplicitThis, strictNullChecks, and strictFunctionTypes set to true.

If changing an existing definition:

Provide a URL to documentation or source code which provides context for the suggested changes: <>
If this PR brings the type definitions up to date with a new version of the JS library, update the version number in the header.

If removing a declaration:

If a package was never on Definitely Typed, you don't need to do anything. (If you wrote a package and provided types, you don't need to register it with us.)
Delete the package's directory.
Add it to notNeededPackages.json.

types/node/http.d.ts

+        'content-disposition'?: string | undefined;
+        'content-encoding'?: string | undefined;
+        'content-language'?: string | undefined;
+        'content-length'?: string | undefined;


number often used for 'content-length'

thanks, fixed

Semigradsky · 2023-09-22T04:47:03Z

types/node/http.d.ts

-    interface OutgoingHttpHeaders extends NodeJS.Dict<OutgoingHttpHeader> {}
+    interface OutgoingHttpHeaders extends NodeJS.Dict<OutgoingHttpHeader> {
+        accept?: string | undefined;
+        'accept-charset'?: string | undefined;


string[] can be used almost with all headers

Is the same applied to IncomingHeaders? If so, I propose we match them, because as of right now, most incoming headers accept only string.

See https://github.com/nodejs/node/blob/31e727db7e0f57bd71d35ce8c1cf378bab309b0f/test/parallel/test-http-server-multiheaders2.js#L32-L45 for multiple allowed headers list

Is the same applied to IncomingHeaders?

Not sure, they can be received as joined string. Need testing

Looks like only string for IncomingHeaders: https://github.com/nodejs/node/blob/31e727db7e0f57bd71d35ce8c1cf378bab309b0f/test/parallel/test-http-multiple-headers.js#L23-L29

@skwee357 Unfortunately, this pull request currently has a merge conflict 😥. Please update your PR branch to be up-to-date with respect to master. Have a nice day!

types/node/http.d.ts

+        'content-disposition'?: string | undefined;
+        'content-encoding'?: string | undefined;
+        'content-language'?: string | undefined;
+        'content-length'?: string | number | undefined;


This assumption is dangerously wrong. headers are usually strings and have to be casted manually.

In examples and tests Node.js team often use number for 'content-length'. The same in real world. Not sure that need to break it.

Do you have a link?

In examples:

https://nodejs.org/dist/latest-v20.x/docs/api/http.html#responsewriteheadstatuscode-statusmessage-headers

https://nodejs.org/dist/latest-v20.x/docs/api/http2.html#http2streamrespondwithfdfd-headers-options

In tests:

https://github.com/nodejs/node/blob/c829c03df2451212d1d6d28e867579e5d5e4a06e/test/async-hooks/test-http-agent-handle-reuse-serial.js#L63

https://github.com/nodejs/node/blob/c829c03df2451212d1d6d28e867579e5d5e4a06e/test/parallel/test-http-allow-content-length-304.js#L11

https://github.com/nodejs/node/blob/c829c03df2451212d1d6d28e867579e5d5e4a06e/test/parallel/test-http-client-spurious-aborted.js#L14

and many others...

Ok, it will converted to string internally...

+        'sec-websocket-version'?: string | undefined;
+        server?: string | undefined;
+        'set-cookie'?: string[] | undefined;


Imho set-cookie can be also a single string.

Apologies for the back-and-forth. I'm not focused recently

Semigradsky · 2023-09-27T05:45:46Z

@skwee357 Looks good! 👍 Currently you added it for Node.js v20 and TypeScript > 4.8

Need to add also

to folder types/node/ts4.8 for TypeScript <= 4.8
to folders types/node/v18, types/node/v18/ts4.8, types/node/v16, types/node/v16/ts4.8 for other Node.js versions

Ready to merge

JandenMa · 2023-09-29T18:52:58Z

It is not compatible with the header type of aws4. It broke our deployment. 😔 @mhart

skwee357 · 2023-09-30T00:03:58Z

@JandenMa I apologize for that.
My understanding is that aws4 expects accept header to be a string, rather than string[]?

As pointed out by @Semigradsky here https://github.com/nodejs/node/blob/31e727db7e0f57bd71d35ce8c1cf378bab309b0f/test/parallel/test-http-server-multiheaders2.js#L32-L45 accept header could be an array.

As a temporary solution, maybe you can force cast it to satisfy the problematic package? I would also suggest opening an issue / PR to the problematic package.

JandenMa · 2023-09-30T04:47:31Z

@skwee357 Thanks for your response.
I think aws4 depends on the old @types/node version.
And no worries I use resolutions to force indirect dependencies to install 18.18.0, it works for now.
Could you let me know when the problematic package is upgraded or resolved?

Semigradsky · 2023-09-30T08:43:50Z

@JandenMa what the type HeadersInit?

JandenMa · 2023-09-30T08:53:24Z

@Semigradsky

Semigradsky · 2023-09-30T09:04:16Z

Ok, looks like aws4 is okay and just HeadersInit from lib.dom.d.ts and ...HttpHeaders from @types/node incompatible. How you use these headers then? Maybe you not need type HeadersInit here.

JandenMa · 2023-09-30T09:10:41Z

Well I use the createHttpLink from the @apollo/client for signable requests, the options of fetch argument requires RequestInit type, and the headers of options requires HeadersInit type. @Semigradsky

Semigradsky · 2023-09-30T09:41:20Z

Do you use node-fetch? Or 'native' fetch from Node.js?

JandenMa · 2023-09-30T09:41:43Z

native one~

Semigradsky · 2023-09-30T10:01:20Z

In this case looks like issue should be gone after #66824 when you will use types from @types/node instead of fetch from lib.dom.d.ts.

JandenMa · 2023-09-30T10:10:14Z

Hmmm I don't think that's what I can control though.
The issue I think from aws4.sign, the headers from it that seems different type from the @types/node change. But I could be wrong.

Semigradsky · 2023-09-30T10:12:09Z

No, they are the same, see

DefinitelyTyped/types/aws4/index.d.ts

Line 38 in 5d599be

headers?: OutgoingHttpHeaders;

JandenMa · 2023-09-30T10:20:42Z

Oh, it refers to the same type.
Alright, I will try to import types from @types/node instead of lib.dom.d.ts (global) when #66824 is merged. That's what you meant right?
Btw, could you let me know after merging?

JandenMa · 2023-09-30T10:31:42Z

Thank you @Semigradsky 😋
