angular - Ionic 3 中的 Algolia Instantsearch.js

我正在尝试在我的 Ionic 3 应用程序中使用来自 Algolia 的 instantsearch.js 库。这是我遵循的教程。

https://angularfirebase.com/lessons/angular-full-text-search-with-algolia-frontend-part-1/

这是我得到的错误

_WEBPACK_IMPORTED_MODULE_3_instantsearch_js__.instantsearch is not a function

我已经使用以下命令通过 npm 导入了它。

npm install instantsearch.js --save

SearchPage.ts

import { Component } from '@angular/core';
import { IonicPage, NavController, NavParams } from 'ionic-angular';
import { ALGOLIA_CONFIG } from './../../app/app.algolia.config';
import * as instantsearch from 'instantsearch.js';

@IonicPage()
@Component({
  selector: 'page-search',
  templateUrl: 'search.html',
})
export class SearchPage {

  search: any;

  constructor(public navCtrl: NavController, public navParams: NavParams) {
  }

  ionViewDidLoad() {
    console.log('ionViewDidLoad SearchPage');
    console.log(ALGOLIA_CONFIG);
    console.log(instantsearch)
    this.search = instantsearch(ALGOLIA_CONFIG);
    // search box widget
    this.search.addWidget(
      instantsearch.widgets.searchBox({
        container: '#search-box',
        autofocus: false,
        placeholder: 'Search for actors',
        poweredBy: true
      })
    );

    // initialize hits widget
    this.search.addWidget(
      instantsearch.widgets.hits({
        container: '#hits',
        templates: {
          empty: 'No results',
          item: `<img src=https://image.tmdb.org/t/p/w300{{image_path}} width="50px">
                <strong>Result {{objectID}}</strong>:
                {{{_highlightResult.name.value}}}`
        },
        escapeHits: true
      })
    );

    this.search.addWidget(
      instantsearch.widgets.stats({
        container: '#stats'
      })
    );

    this.search.addWidget(
      instantsearch.widgets.pagination({
        container: '#pagination',
        maxPages: 20,
      })
    );

    this.search.addWidget(
      instantsearch.widgets.analytics({
        pushFunction: (query, state, results) => {
          console.log(query)
          console.log(state)
          console.log(results)
        }
      })
    );

    this.search.start();
  }

}

搜索.html

<ion-header>

  <ion-navbar>
    <ion-title>Search</ion-title>
  </ion-navbar>

</ion-header>


<ion-content padding>
  <h1>Test Algolia</h1>

  <div id="search-box">
    <!-- SearchBox widget will appear here -->
  </div>
  <div id="stats">
    <!-- stats widget will appear here -->
  </div>
  <div id="hits">
    <!-- Hits widget will appear here -->
  </div>
  <div id="pagination">
    <!-- pagination widget will appear here -->
  </div>
</ion-content>

我也试过在没有/es 的情况下导入它。

这是 console.log(instantsearch) 的输出

最佳答案

您可以尝试以这种方式导入即时搜索吗:

import instantsearch from 'instantsearch.js/es';
import { searchBox } from 'instantsearch.js/es/widgets';

这样，它将导入唯一需要的模块，并且应该可以在 Angular2/Ionic 应用程序中工作。

如果你想了解更多关于如何在 Angular2/Ionic 应用程序中集成 Instantsearch.js，你应该在这里阅读我们的集成指南:https://community.algolia.com/instantsearch.js/v2/guides/angular-integration.html

我们也在积极努力发布 angular-instansearch 库，这将在接下来的几个月内实现。如果您有兴趣加入 Beta 计划，请填写此文件:https://docs.google.com/forms/u/2/d/e/1FAIpQLSeqEHS0VjnNlaKMp7Cm0y7pRe2pLz-39y3-cEAs5o-H0-HD6A/viewform?usp=send_form
