Toolkit can run in web browser (e.g. vscode.dev), avoid nodejs APIs

[justinmk3]

Toolkit currently doesn't support "web" version of vscode, https://vscode.dev

Considerations

• https://code.visualstudio.com/blogs/2021/10/20/vscode-dev#_extensions

  For example, change https://github.com/microsoft/vscode to https://vscode.dev/github.com/Microsoft/vscode. If you are not on GitHub or Azure DevOps, support for additional repository hosting services can be provided through extensions, just like on the desktop.

• Need to avoid direct interaction (nodejs api) with the OS
  • fileystem in favor the "virtual fs" (VFS) layer
  • network (use vscode api for http requests instead)
• Could help with "minimum trust". #1823

What can AWS Toolkit do with/without "compute"?

• without compute: we can make SDK calls and network requests, so features like these can work, in theory:
  • AWS Explorer
  • Language services (LSP, JSON-schema)
• with compute: we can use features that require a filesystem and operating system:
  • SAM CLI
  • Docker

Getting credentials when running in browser

• @aws-sdk/credential-providers fromWebToken()
• https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/webpack.html#webpack-configuring
• import { fromWebToken } from "@aws-sdk/credential-providers";
  • causes: Module not found: Error: Can't resolve 'path' in '.../node_modules/@aws-sdk/credential-providers/node_modules/@aws-sdk/shared-ini-file-loader/dist-es'
• import { fromWebToken } from "@aws-sdk/credential-providers/dist-es/fromWebToken";
  • or import { fromWebToken } from "@aws-sdk/credential-provider-web-identity";
  • causes: Module not found: Error: Can't resolve 'fs' in '.../node_modules/@aws-sdk/credential-provider-web-identity/dist/es'
• import { fromWebToken } from "@aws-sdk/credential-provider-web-identity/dist/es/fromWebToken";
  • works but requires rewriting glue code from https://github.com/aws/aws-sdk-js-v3/blob/main/packages/credential-providers/src/fromWebToken.ts
