Install node modules

cd app

npm install

Set region and endpoint in SeaweedUploaderS3API.ts

and then to pack and run the app:

npx snowpack dev --polyfill-node

to fix: Uncaught SyntaxError: The requested module '/_snowpack/pkg/@aws-crypto.sha1-browser.v2.0.0.js' does not provide an export named 'Sha1' (at @aws-sdk.client-s3.v3.170.0.js:22:10)

Navigate to: \s3-multipart-error\app\node_modules\.cache\snowpack\build\@aws-crypto\[email protected]\@aws-crypto\sha1-browser.js

At the bottom of the file change:

export { Ie11Sha1, WebCryptoSha1, build as __moduleExports };

to:

export { Ie11Sha1, WebCryptoSha1 as Sha1, build as __moduleExports };

Do the same for Sha256 module in first @aws-crypto folder
