Use the fetch available in the environment instead of cross-fetch #389
Description
For cloudflare workers and deno where there is fetch available in the environment already, currently we need initialise the client like this
const supabase = createClient(
"https://yyy.supabase.co", "xxx", {
fetch: fetch.bind(globalThis),
}
);Instead we should use the following algorithm to get fetch
- Use the custom fetch option when provided
- Use the global fetch if available
- else use cross-fetch
With Node implementing the fetch standard soon, fetch is a global we can reasonably assume the existence of in most envionments and only load cross-fetch as a polyfill. cross-fetch also assumes the presence of XMLHttpRequest which leads to a lot of errors.
Client libraries to update
- storage-js
- postgrest-js
- realtime-js (doesn't use fetch)
- gotrue-js
