[![Go Report Card](https://goreportcard.com/badge/git.ailur.dev/ailur/jsFetch)](https://goreportcard.com/report/git.ailur.dev/ailur/jsFetch) [![Go Reference](https://pkg.go.dev/badge/git.ailur.dev/ailur/jsFetch.svg)](https://pkg.go.dev/git.ailur.dev/ailur/jsFetch)
The API is exactly the same as net/http.
The API is exactly the same as net/http.
## Important note
It is common for it to return the error "Failed to fetch" with the error ERR_H2_OR_QUIC_REQUIRED in Chromium-based browsers. To fix this, you are able to modify the request to set `request.DisableStreamedClient` to `true`. This is because Chromium has a method of upload ReadableStream data that requires HTTP/2 or QUIC to be enabled for security reasons.
