Google Image Fetcher is a JavaScript library that simplifies the process of fetching and saving images from Google Search using the Custom Search JSON API.
Frontend developers often face the challenge of sourcing images for their websites when there is no graphic designer available on the team. This JavaScript library aims to solve that problem by providing an easy-to-use solution for fetching and downloading images from Google.
You can use this library without any prior knowledge of JavaScript programming, making it accessible to both developers and non-developers.
After following the steps outlined below, you'll be able to download images based on your query and view the image URLs in the terminal.

└── README.mdYou can install the library using npm:
npm install google-image-fetcher-
Create a new JavaScript (.js) file in your project folder.
-
Copy and paste the following code into your .js file:
const GoogleImageFetcher = require('google-image-fetcher'); // Create an instance of GoogleImageFetcher (no need to pass API Key and CX ID here) const imageFetcher = new GoogleImageFetcher(); // Define the query and the save folder (optional) const query = 'YOUR_QUERY'; const saveFolder = 'YOUR_FOLDER_NAME'; // Call the fetchImages method to fetch and save images imageFetcher.fetchImages(query, saveFolder);
-
Replace
YOUR_QUERYwith the desired image search query andYOUR_FOLDER_NAMEwith the name of the folder where you want to save the downloaded images. This folder will be created in your project's current directory.
Now you're ready to use the library to fetch and save images.
In a React application, you would typically use JavaScript modules and ES6 imports instead of require. Here's the equivalent code for your example using ES6 imports in a React component:
import React, { useEffect } from 'react';
import GoogleImageFetcher from 'google-image-fetcher';
const YourComponent = () => {
useEffect(() => {
// Create an instance of GoogleImageFetcher (no need to pass API Key and CX ID here)
const imageFetcher = new GoogleImageFetcher();
// Define the query and the save folder (optional)
const query = 'YOUR_QUERY';
const saveFolder = 'YOUR_FOLDER_NAME';
// Call the fetchImages method to fetch and save images
imageFetcher.fetchImages(query, saveFolder);
// Make sure to include any necessary dependencies in the dependency array
}, []);
return (
<div>
{/* Your React component content */}
</div>
);
};
export default YourComponent;In this code:
- We're using the
importstatement to importGoogleImageFetcherfrom the 'google-image-fetcher' package. - Inside a functional component (
YourComponent), we use theuseEffecthook to run code when the component mounts. This is similar to the code you provided that runs when the module is imported. - We create an instance of
GoogleImageFetcherand then callfetchImageswith your desiredqueryandsaveFolder. This code will execute when the component is mounted due to the empty dependency array[]. - You can replace
<div>{/* Your React component content */}</div>with your actual component content.
Remember to include any necessary dependencies in the dependency array of the useEffect hook to ensure the code runs only when those dependencies change. If you need to execute the code in response to specific events or user actions, you can adjust the useEffect accordingly.
In an Angular application, you would follow a different structure and syntax compared to React. Here's how you can integrate the code for fetching images using google-image-fetcher into an Angular component:
Assuming you have an Angular project set up, follow these steps:
-
Import and Use in an Angular Component:
Create an Angular component where you want to use
google-image-fetcher. Import the library and use it in your component's TypeScript file. Below is an example of how to do this:// Import statements import { Component, OnInit } from '@angular/core'; import { GoogleImageFetcher } from 'google-image-fetcher'; @Component({ selector: 'app-image-fetcher', template: ` <div> <!-- Your Angular component content --> </div> `, }) export class ImageFetcherComponent implements OnInit { constructor() {} ngOnInit() { // Create an instance of GoogleImageFetcher (no need to pass API Key and CX ID here) const imageFetcher = new GoogleImageFetcher(); // Define the query and the save folder (optional) const query = 'YOUR_QUERY'; const saveFolder = 'YOUR_FOLDER_NAME'; // Call the fetchImages method to fetch and save images imageFetcher.fetchImages(query, saveFolder); } }
In this code:
- We import the
GoogleImageFetcherclass from the 'google-image-fetcher' package. - We create an Angular component (
ImageFetcherComponent) where we useGoogleImageFetcherinside thengOnInitlifecycle hook, which runs when the component initializes. - We define the
queryandsaveFoldervariables with your desired values. - We create an instance of
GoogleImageFetcherand call thefetchImagesmethod to fetch and save images. - You can replace the template content with your actual Angular component content.
- We import the
-
Add the Component to Your Angular Module:
Make sure to add your
ImageFetcherComponentto the declarations array of your Angular module (e.g.,app.module.ts) to make it available for use in your application.import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { AppComponent } from './app.component'; import { ImageFetcherComponent } from './image-fetcher.component'; // Import your component @NgModule({ declarations: [AppComponent, ImageFetcherComponent], // Add your component here imports: [BrowserModule], bootstrap: [AppComponent], }) export class AppModule {}
-
Include in Template:
Include your
ImageFetcherComponentin the template of another Angular component or in your Angular routing configuration as needed.
Now, your Angular component is set up to use google-image-fetcher. When you navigate to the component or use it in your application, the code inside ngOnInit will be executed to fetch and save images.
Before using the library, make sure to obtain an API Key and CX ID from the Google Custom Search JSON API. Replace the values in the code with your actual credentials.
