I never found Deno compelling enough compared to Node.

Bun was promising, but as long as they don't fix their http GET implementation to accept the request body, its broken for me.

Note: Many real world tools like Elasticsearch's GET /_search with a JSON query DSL is one example. It breaks Axios. Many custom infrastructure tools expect it.

Advertising as node compatible and having this breaking change is undesirable. Hope it gets fixed soon.

You shouldn't be sending a body with a GET request. Sounds like your code is broken.

▲

No. There are use cases for GET with body. Curl allows it. Node allows it. Bun doesn't.

There may be use-cases (and the RFC allows ignoring the SHOULD clause with enough reasoning), but GET does not have a request body as per specification, and a LOT of things drop it because of that (most notably - nginx! Also applies to HAProxy and Apache HTTP server afaik, but also a bunch of load balancers)

no.

Wrong.

Hint: Elasticsearch, GraphQL, Axios, etc..

GraphQL uses POST for queries.

		Many GraphQL clients/libraries use GET with body to workaround hitting URL query limitations like length, etc. Spec is not the same as compatibility.

Enabling the GET implementation to "accept the request body" would literally be the opposite of fixing it. The broken thing here is your expectation. You are looking for POST (or possibly PUT).

You would be surprised how many technologies expect GET with a body. In practical backend engineering, tools like Elasticsearch, GraphQL, complex query engines, and legacy internal APIs rely on GET with a body every day. Apparently even axios messes up on curl GET requests with a body as mentioned in the associated github issue.

Perhaps the broken thing might be how you expect existing softwares to break so that your expectation can be satisfied. You should look at GET more closely.

There is a reason curl allows to send GET requests with a body. There is a reason node allows to receive GET requests with a body.

A request body in a GET is not standard HTTP. Refusing to handle non-standard requests might be inconvenient, but it's an eminently defensible choice.

I understand why you'd want it, and that's why RFC10008 introduces QUERY as a GET-with-body alternative.

	▲	elendilm an hour ago \| parent \| next [-]
		QUERY, added in 2026, does not resolve existing or legacy applications. Sticking to RFC is one thing. Advertising as node compatible is completely different altogether. Many people cannot see the difference. Atleast a flag would suffice as that would ensure existing infrastructure tooling doesn't break while keeping the RFC spec folks happy.

		Technically every http method can have a body? But the specification says the semantics are undefined on get and any compliant implementation is free to ignore it.

It was funny a few years ago, when I had to grade students answering a quiz about web services. There was a question about which components were necessary for a valid GET request. The required answer was a list of 4-5 components, such as the "GET" verb, the URI, the HTTP version, etc.

And it was rather controversial that some listed a body as necessary for a GET request, and doing my research I came to find out that a "request body" was often quite undesirable and perhaps contrary to the RFC standards, and sending a "body" in a GET could result in undefined or unpredictable behavior. But it's all in good fun.

They just implement the fetch api from the web, does the fetch api allow get’s to have a body?

▲

Node allows it. Curl allows. Not having it is a breaking change and undesirable for node compatibility.

If you need bug-for-bug node compatibility you should be using node.

	▲	elendilm an hour ago \| parent [-]
		Your "bug-for-bug" compatibility ensures Axios, Elasticsearch, many GraphQL implementations, etc. works. Hence I will use node as mentioned in my original comment. You should use bun :)

A body is technically allowed on any http request but it doesn’t mean anything on a get, a server is free to ignore it, anything in the middle is free to strip it, etc.
