Failed to import - fetch-blob

[talentlessguy]

Failing module

• GitHub: https://github.com/node-fetch/fetch-blob
• npm: https://www.npmjs.com/package/fetch-blob

import { Blob } from 'https://esm.sh/fetch-blob'

Error message

After running deno run I get this:

/* esm.sh - error */
throw new Error("[esm.sh] " + "Could not resolve \"stream/web\"");
export default null;

Additional info

• esm.sh version: v53
• Deno version: 1.14

The line causing this issue: https://github.com/node-fetch/fetch-blob/blob/0e074572462f2df71c2507f187f164c61376257e/streams.cjs#L7

The module that needs to be added to polyfills: https://nodejs.org/api/webstreams.html#webstreams_web_streams_api

I can see now it is working

curl https://esm.sh/fetch-blob

shows

/* esm.sh - [email protected] */
export * from "https://cdn.esm.sh/v53/[email protected]/es2021/fetch-blob.js";
export { default } from "https://cdn.esm.sh/v53/[email protected]/es2021/fetch-blob.js";

Cheers

@Stradivario do named exports (i.e. Blob) work as well?

[Stradivario]

As far as i can see yes :)

[talentlessguy]

@Stradivario try with deno run

new error now on v55:

➜ deno eval 'import { Blob } from \'https://esm.sh/fetch-blob\''

blocked by this on v57: denoland/std#1519 (not esm.sh bug)

[talentlessguy]

main module is now importing fine on v58 but fetch-blob/from.js breaks because of worker_threads:
