This SDK is intended to be used in JavaScript runtimes that support ECMAScript 2020 or newer. The SDK uses the following features:
- Web Fetch API
- Web Streams API and in particular
ReadableStream
- Async iterables using
Symbol.asyncIterator
Runtime environments that are explicitly supported are:
- Evergreen browsers which include: Chrome, Safari, Edge, Firefox
- Node.js active and maintenance LTS releases
- Currently, this is v18 and v20
- Bun v1 and above
- Deno v1.39
- Note that Deno does not currently have native support for streaming file uploads backed by the filesystem (issue link)
The following tsconfig.json
options are recommended for projects using this
SDK in order to get static type support for features like async iterables,
streams and fetch
-related APIs (for await...of
,
AbortSignal
, Request
, Response
and
so on):
{
"compilerOptions": {
"target": "es2020", // or higher
"lib": ["es2020", "dom", "dom.iterable"],
}
}
While target
can be set to older ECMAScript versions, it may result in extra,
unnecessary compatibility code being generated if you are not targeting old
runtimes.
