Add client libraries for NestJS backend and Axios frontend

[Copilot]

Implements client modules to consume the storage service from both NestJS microservices and frontend applications (React, Vue, Angular).

Implementation

NestJS Backend Client (src/client/nestjs/)

• StorageClientModule with sync/async registration supporting ConfigService
• StorageClientService providing typed methods for all API operations
• Uses @nestjs/axios with RxJS observables

Axios Frontend Client (src/client/axios/)

• StorageClient class for browser environments
• Helper methods for file uploads and multipart uploads
• Authentication support via setAuthToken() and setHeaders()

Shared Types (src/client/shared/)

• Common TypeScript interfaces for requests/responses across both clients
• 15+ typed interfaces covering all API operations

Usage

NestJS:

@Module({
  imports: [
    StorageClientModule.register({
      baseUrl: 'http://localhost:4000',
    }),
  ],
})
export class AppModule {}

Frontend:

const client = new StorageClient({ baseUrl: 'http://localhost:4000' });

const object = await client.createObject({
  namespace: 'documents',
  name: 'file.pdf',
  contentType: 'application/pdf',
  sizeBytes: 1024000,
});

await client.uploadFile(object.uploadUrl, file);

Package Exports

Added clean import paths via package.json exports:

• @pnstack/nestjs-storage-service/client/nestjs
• @pnstack/nestjs-storage-service/client/axios
• @pnstack/nestjs-storage-service/client/shared

Security

Updated axios to v1.12.2 to patch DoS and SSRF vulnerabilities (CVE-2024-xxxxx).

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• scarf.sh

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

implement client module for both backend microservice nestjs and frontend with axios in shared module
