Data processing

This library allows processing documents/files using Generative AI.

It currently provides a single functionality that summarizes PDFs sent to an API

Summary

Enabling the summary is super easy. All you need to do apart from the standard file interceptor is to add the provided pipe and to request a SummaryEnrichedFile which will inject the file along with the summary in your controller's function.

import {

  Controller,
  Post,

  UsePipes,
} from '@nestjs/common';
import {
  SummaryEnrichedFile,
  AISummarizeDocumentPipe,
} from 'nestjs-generative-ai';
import { FileInterceptor } from '@nestjs/platform-express';

@Controller()
export class AppController {
  @Post('/file')
  @UseInterceptors(FileInterceptor('file'))
  @UsePipes(AISummarizeDocumentPipe)
  async uploadFile(@UploadedFile() file: SummaryEnrichedFile) {
    return file.summary;
  }
}
