npm install @angular/core

import { Component } from '@angular/core';
import { LocalStorageService } from 'ngstorage';

@Component({
  selector: 'app-storage',
  template: `
    <button (click)="storePdf()">存储PDF</button>
  `
})
export class StorageComponent {
  constructor(private storage: LocalStorageService) {}

  storePdf() {
    // 读取PDF文件，可以使用File API或其他相关库
    const pdfFile = ...;

    // 将PDF文件存储到PouchDB中
    this.storage.set('pdf', pdfFile);
  }
}

import { Component } from '@angular/core';
import { LocalStorageService } from 'ngstorage';
import PouchDB from 'pouchdb';

@Component({
  selector: 'app-storage',
  template: `
    <button (click)="storePdf()">存储PDF</button>
  `
})
export class StorageComponent {
  private pouchDB: PouchDB.Database;

  constructor(private storage: LocalStorageService) {
    this.pouchDB = new PouchDB('pdfs');
  }

  storePdf() {
    // 读取PDF文件，可以使用File API或其他相关库
    const pdfFile = ...;

    // 将PDF文件转换为Base64编码的字符串
    const pdfData = btoa(pdfFile);

    // 将PDF文件存储到PouchDB中
    this.pouchDB.put({
      _id: 'pdf',
      data: pdfData
    }).then(() => {
      console.log('PDF文件已存储到PouchDB中');
    }).catch((error) => {
      console.error('存储PDF文件时出错：', error);
    });
